Andlandl: stk1160 limitations

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] or GM7113 (Philips SAA7113 compatible video decoder chips)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing (2 chip stk1160 Easycaps) audio capturing is done by the STK1160 chips built-in 8 bit ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip (currently not supported by the stk1160 driver)

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===

==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports:
* V4L2 video capturing
* audio capturing via ALSA (only the 48000Hz Easycap is supported)

====== Enable sound capture ======

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the '''snd_usb_audio''' module.

On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the '''Line''' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

===== Limitations =====

====== AC'97 audio only ======

The stk1160 module only supports audio capturing from the CVBS + S-Video Easycap with builtin AC'97 chip (3 chip stk1160 Easycap; 48000Hz model). Adding support for the 8 bit ADC in the stk1160 chip is planned in the future.

If you have the 4 CVBS model or the CVBS + S-Video model without AC'97 chip the dmesg messages look like this:
# dmesg
[12677.625434] usb 2-2: new high-speed USB device number 8 using ehci-pci
[12677.740513] usb 2-2: New device Syntek Semiconductor USB 2.0 Video
Capture Controller @ 480 Mbps (05e1:0408, interface 0, class 0)
[12677.740517] usb 2-2: video interface 0 found
[12678.217418] stk1160: driver ver 0.9.5 successfully loaded
[12678.220618] '''AC'97 0 access is not valid [0x0], removing mixer.'''
[12678.220623] stk1160: registers to NTSC like standard
[12678.221681] stk1160 2-2:1.0: V4L2 device registered as video1
In this case you maybe can get some crappy sound through the '''Controlle''' soundcard created by the '''snd_usb_audio''' module, but if you want to capture hight quality sound you need to plug in the audio source to the Line in plug of your built-in soundcard. (You only need to change the number of the sound device in the capturing program if you want to watch/ record video with sound.)

====== Framescaling is not supported ======

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.
This is important for some programs where setting width and height of the video stream (e.g. Zonemeinder) is necessary. Other settings than 720x576 PAL or 720x480 NTSC may cause proplems with those programs.

====== Known issue ======

Easycap devices which have the gm7113 video decoder chip (saa7113 clone) inside don't work on stk1160 but do work
on the legacy easycap driver. This issue will be solved in kernel 3.11 (expected).

===== Sourcecode =====

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use the s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The eascap module supports audio from the 48000Hz and the 8000Hz models.

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

If you encounter audio problems while capturing you need to specify the correct audiorate of your model (48000 or 8000) in the capturing program.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the legacy easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-16T07:54:55Z

Andlandl: stk1160 limitations

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] or GM7113 (Philips SAA7113 compatible video decoder chips)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing (2 chip stk1160 Easycaps) audio capturing is done by the STK1160 chips built-in 8 bit ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip (currently not supported by the stk1160 driver)

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===

==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports:
* V4L2 video capturing
* audio capturing via ALSA (only the 48000Hz Easycap is supported)

====== Enable sound capture ======

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the '''snd_usb_audio''' module.

On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the '''Line''' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

===== Limitations =====

====== AC'97 audio only ======

The stk1160 module only supports audio capturing from the CVBS + S-Video Easycap with builtin AC'97 chip (3 chip stk1160 Easycap; 48000Hz model). Adding support for the 8 bit ADC in the stk1160 chip is planned in the future.

If you have the 4 CVBS model or the CVBS + S-Video model without AC'97 chip the dmesg messages look like this:
# dmesg
[12677.625434] usb 2-2: new high-speed USB device number 8 using ehci-pci
[12677.740513] usb 2-2: New device Syntek Semiconductor USB 2.0 Video
Capture Controller @ 480 Mbps (05e1:0408, interface 0, class 0)
[12677.740517] usb 2-2: video interface 0 found
[12678.217418] stk1160: driver ver 0.9.5 successfully loaded
[12678.220618] '''AC'97 0 access is not valid [0x0], removing mixer.'''
[12678.220623] stk1160: registers to NTSC like standard
[12678.221681] stk1160 2-2:1.0: V4L2 device registered as video1
In this case you maybe can get some crappy sound through the '''Controlle''' soundcard created by the '''snd_usb_audio''' module.

====== Framescaling is not supported ======

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.
This is important for some programs where setting width and height of the video stream (e.g. Zonemeinder) is necessary. Other settings than 720x576 PAL or 720x480 NTSC may cause proplems with those programs.

====== Known issue ======

Easycap devices which have the gm7113 video decoder chip (saa7113 clone) inside don't work on stk1160 but do work
on the legacy easycap driver. This issue will be solved in kernel 3.11 (expected).

===== Sourcecode =====

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use the s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The eascap module supports audio from the 48000Hz and the 8000Hz models.

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

If you encounter audio problems while capturing you need to specify the correct audiorate of your model (48000 or 8000) in the capturing program.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the legacy easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-15T17:54:06Z

Andlandl: stk1160 audio limitations

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] or GM7113 (Philips SAA7113 compatible video decoder chips)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip (currently not supported by the stk1160 driver)

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports:
* V4L2 video capturing
* audio capturing via ALSA (only the 48000Hz Easycap is supported)

===== Framescaling is not supported =====

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.
This is important for some programs where setting width and height of the video stream (e.g. Zonemeinder) is necessary. Other settings than 720x576 PAL or 720x480 NTSC may cause proplems with those programs.

===== Sourcecode =====

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use the s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== Stk1160 audio support =====

The stk1160 module only supports audio capturing from the CVBS + S-Video Easycap with builtin AC'97 chip (3 chip Easycap; 48000Hz model). Adding support for the 8 bit ADC in the stk1160 chip is planned in the future

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

====== Enable sound capture ======
On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

Te eascap module supports audio from the 48000Hz and the 8000Hz models.

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

If you encounter audio problems while capturing you need to specify the correct audiorate of your model (48000 or 8000) in the capturing program.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the legacy easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-03T11:38:43Z

Andlandl:

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports:
* V4L2 video capturing
* audio capturing via ALSA only

===== Framescaling is not supported =====

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.
This is important for some programs where setting width and height of the video stream (e.g. Zonemeinder) is necessary. Other settings than 720x576 PAL or 720x480 NTSC may cause proplems with those programs.

===== Sourcecode =====

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use the s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== Stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

====== Enable sound capture ======
On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the legacy easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-03T10:15:33Z

Andlandl: swap stk1160 and easycap driver information

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports video capturing and audio capturing via ALSA only.

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use the s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

====== Enable sound capture ======
On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the old easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-03T10:13:07Z

Andlandl:

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).

The stk1160 module supports video capturing and audio capturing via ALSA only.

Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use th s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

====== Enable sound capture ======
On a fresh installed system, or if you have installed the driver by yourself, you once (!) need to enable sound capture from '''stk1160-mixer''' in the mixer settings.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the '''Controlle''' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-03T10:07:52Z

Andlandl:

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).
The stk1160 module supports video capturing and audio capturing via ALSA.
Unlike the legacy easycapdriver the stk1160 driver doesn't support framescaling.

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use th s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the old easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2013-06-03T10:01:55Z

Andlandl:

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== stk1160 driver ====
The stk1160 driver is in the mainline kernel since version 3.7. It is the successor of the legacy easycap driver (see below).
The stk1160 module supports video capturing and audio capturing via ALSA.
This driver doesn't suffer from the limitations of the easycap driver. The stk1160 module replaces the easycap module in the 3.7 kernel release.

If you want to use the stk1160 driver under previous kernels (3.2, 3.4 or 3.6 kernel only !), you can get the sourcecode frome here:

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

Select the svideo2_for_3.2 version if you want to use th s-video input of yout stk1160 device.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

==== legacy easycap driver ====
The easycap driver is part of the kernel from 2.6.38 up to 3.6.x and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the old easycapdriver has been replaced by the stk1160 driver.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver. The stk1160 module replaces the easycap module in the 3.7 kernel release.

If you want to use the stk1160 driver in the 3.2, 3.4 or 3.6 kernel, you can get the sourcecode frome here:

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the old easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2012-11-06T11:54:12Z

Andlandl:

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing [http://ubuntuforums.org/showthread.php?t=924504&page=3 patches] for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In the 3.7 kernel release the old easycapdriver has been replaced by the stk1160 driver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-27T10:28:46Z

Andlandl: Capturing format

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Video capturing up to 720x576px @ 25fps (PAL) and 720x480px @ 30fps (NTSC)
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[https://github.com/ezequielgarcia/stk1160-standalone/zipball/for_v3.2 stk1160 sourcecode-zipball for kernel 3.2]

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-25T15:32:07Z

Andlandl: History

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[https://github.com/ezequielgarcia/stk1160-standalone/zipball/for_v3.2 stk1160 sourcecode-zipball for kernel 3.2]

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-25T15:27:55Z

Andlandl: History

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the STK1160 based video capture device which is sold as EasyCAP DC60. He used the [http://sourceforge.net/projects/syntekdriver/ stk11xx] driver and some existing patches for the "05e1:0408" Syntek device as a basis for his project. Since the easycapdriver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

[[File:Easycap001.png|right]]Many USB video capture devices are sold as EasyCAP.

It seems that EasyCAP is not a companys or brand name, but some chinese manufacturers use this label for at least '''four completly hardware different clones''' of equally looking audio and video capture devices. EasyCAP devices and clones are vastly sold in onlineshops at low prices.

This article describes, how to identify the chipset of the known EasyCAP devices and if they are supported/ working under Linux.

== Overview/Features ==
* All the EasyCAP devices and clones need a USB 2.0 connection (USB 1.1 is too slow).
* They are tunerless but can capture analogue video up to 720x576 px (PAL) or 720x480 px (NTSC) and
* stereosound up to 48000 Hz sampling rate (or only 8000 Hz mono on some models where the AC'97 chip is missing)
* Most of them have input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R).
* Some models do have 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable.

===Components Used===
The components of the different EasyCAP labeled devices are mentioned in the [[Easycap#Known_Easycap_devices| "Known Easycap devices"]] section below.

===Identification===
==== Indentify the device before buying ====
It is hard to identify the chipset of any EasyCAP device before buying because most onlineshops (ebay, amazon) do not mention in the provided technical data the chipset of the device.
[http://www.logilink.de/showproduct/VG0001.htm Example from logilik.de where the chipset is declared]
===== Identify device using installation instructions for Windows =====
[[File:windows-installer.png|right|150px]]If the chipset is not mentioned in device specifications on the website, one way to figure out the chipset inside the EaysCAP is to read through the installation instructions for Windows (if provided for download).
Screenshots of the windowsinstaller often reveal the devicename.

* STK1160 EasyCAP is in Windows: '''(Syntek) STK1160''' or '''STK1150'''
* Empia EasyCAP is in Windows: '''USB 2861 Device''' or '''EMP'''
* Somagic EasyCAP is in Windows: '''SM-USB 007''' or '''SMI Grabber Device'''
* UTV007 based EasyCAP is in Windows: '''USBTV007'''

Stk1160 based USB 2.0 video and audio capture devices

2012-08-24T09:56:19Z

Andlandl: syntec link

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip from [http://www.stk.com.tw/product-01.asp?Product_Type=32 Syntec Semiconductor.co.ltd.]. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb

[[Stk1160#Full_lsusb_-v_output|lsusb -v see below]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

[https://github.com/ezequielgarcia/stk1160-standalone/zipball/for_v3.2 stk1160 sourcecode-zipball for kernel 3.2]

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Easycap

Andlandl: audio support

[[File:Easycap001.png|right]]Many USB video capture devices are sold as EasyCAP.

It seems that EasyCAP is not a companys or brand name, but some chinese manufacturers use this label for at least '''four completly hardware different clones''' of equally looking audio and video capture devices. EasyCAP devices and clones are vastly sold in onlineshops at low prices.

This article describes, how to identify the chipset of the known EasyCAP devices and if they are supported/ working under Linux.

== Overview/Features ==
* All the EasyCAP devices and clones need a USB 2.0 connection (USB 1.1 is too slow).
* They are tunerless but can capture analogue video up to 720x576 px (PAL) or 720x480 px (NTSC) and
* stereosound up to 48000 Hz sampling rate (or only 8000 Hz mono on some models where the AC'97 chip is missing)
* Most of them have input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R).
* Some models do have 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable.

===Components Used===
The components of the different EasyCAP labeled devices are mentioned in the [[Easycap#Known_Easycap_devices| "Known Easycap devices"]] section below.

===Identification===
==== Indentify the device before buying ====
It is hard to identify the chipset of any EasyCAP device before buying because most onlineshops (ebay, amazon) do not mention in the provided technical data the chipset of the device.
[http://www.logilink.de/showproduct/VG0001.htm Example from logilik.de where the chipset is declared]
===== Identify device using installation instructions for Windows =====
[[File:windows-installer.png|right|150px]]If the chipset is not mentioned in device specifications on the website, one way to figure out the chipset inside the EaysCAP is to read through the installation instructions for Windows (if provided for download).
Screenshots of the windowsinstaller often reveal the devicename.

* STK1160 EasyCAP is in Windows: '''(Syntek) STK1160''' or '''STK1150'''
* Empia EasyCAP is in Windows: '''USB 2861 Device''' or '''EMP'''

Many USB video capture devices are sold as EasyCAP.

It seems that EasyCAP is not a companys or brand name, but some manufacturers use this label for at least four completly '''hardware different''' clones of this USB analogue audio- and videocapturedevice. EasyCAP devices and clones are vastly sold in onlineshops at low prices.

This article describes, how to identify the chipset of the known EasyCAP devices and if they are supported/ working in Linux.

== Overview/Features ==
* All the EasyCAP devices and clones need a USB 2.0 connection (USB 1.1 is too slow).
* They are tunerless but can capture analogue video up to 720x576 px (PAL) or 720x480 px (NTSC) and
* stereosound up to 48000 Hz sampling rate (or only 8000 Hz mono on some models where the AC'97 chip is missing)
* Most of them have input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R).
* Some models do have 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable.

===Components Used===

Stk1160 based USB 2.0 video and audio capture devices

2012-08-17T10:27:13Z

Andlandl: internal link

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Andlandl: moved Stk1160 to Stk1160 based USB 2.0 video and audio capture devices: More clear title, stk1160 is the chips name

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

lsusb -v see below: [[Stk1160#Full_lsusb_-v_output]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

[https://github.com/ezequielgarcia/stk1160-standalone/zipball/for_v3.2 stk1160 sourcecode-zipball for kernel 3.2]

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-17T10:16:55Z

Andlandl: Categories

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

lsusb -v see below: [[Stk1160#Full_lsusb_-v_output]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

===== easycap audio support =====

The easycap module creates an additional ALSA soundcard '''EasyALSA0'''.

Often when the STK1160 device is plugged in the '''snd_usb_audio''' module conflicts with the easycap module and the EasyALSA0 soundcard is not created. As a workaround you need to unplug the device, unload the module (rmmod snd_usb_audio) and then plug in the device again.

==== stk1160 driver ====
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in the 3.7 kernel release.

===== stk1160 audio support =====

The stk1160 module registers a control-only alsa soundcard. This sound card is called '''stk1160-mixer'''.
The real sound capture is done through the '''Controlle''' soundcard which is created after plugging in the STK1160 device by the snd_usb_audio module.

To enable sound capture you have to select in alsamixer the 'Line' item on the capture menu for stk1160-mixer when the STK1160 device is plugged in:
You can do this in the terminal as well with this command:

# amixer -c stk1160mixer sset Line unmute cap

Note! In the viewing- or capturing program you must then select the 'Controlle' soundcard or its number to hear sound!

== Usage ==

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0). 
''From the two or four video cables on the device only one (!) can be used at the same time. If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.''

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio. Get a list of ALSA soundcards with this command:
# cat /proc/asound/cards

''If you encounter audio problems while capturing you need to specify the [[Stk1160#Identify_the_audiotype_of_your_device|correct audiorate]] of your model in the capturing program.''

=== Example for mplayer ===
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:audiorate=48000:forceaudio:immediatemode=0 -ao sdl

=== More programs ===
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-17T09:15:49Z

Andlandl: Switch to template ff

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

===Identification===
# lsusb
Bus 001 Device 003: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

lsusb -v see below: [[Stk1160#Full_lsusb_-v_output]]

==== Identify the audiotype of your device ====

The following shell command reports the audiorate (sampling frequency) of your STK1160 based device:

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

* 48000 = Model with AC'97 chip
* 8000 = Model without AC'97 chip

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.

==Making it Work==
STK1160 based devices ar supported under Linux since kernel 2.6.38

===Drivers===
==== eaysycap driver ====
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).

==External Links==
''Provide a link to the vendor's product page here along with any other external link to information that is generally helpful in relation to the device. For example:''

== How to identify your device ==

When '''lsusb''' reports the following output you have an STK1160 based video capture card:

Bus 001 Device 002: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

== Hardware ==
On the board of this USB 2.0 video capture device there is on the front side a green LED, the STK1160 USB Bridge and a SAA7113 compatible video processing chip (silan sc8113) and on the back side a AC97 audio chip (this chip is missing on the 8000 Hz audio models of this device).
[[File:dc60-front.jpg|350px]]
[[File:dc60-back.jpg|350px]]

== Drivers ==

=== eaysycap driver ===
The easycap driver is part of the current kernel (since 2.6.38) and supports all the features of the STK1160 based devices but has some limitations (framedropping, stability, sound issues).
=== stk1160 driver ===
The stk1160 driver is the successor of the easycap driver. It supports video capturing and audio capturing via ALSA. This driver doesn't suffer from the limitations of the easycap driver but is still under development. It is intended that the stk1160 module will replace the easycap module in one of the next kernel releases.

[https://github.com/ezequielgarcia/stk1160-standalone stk1160 github repository]

[https://github.com/ezequielgarcia/stk1160-standalone/zipball/for_v3.2 stk1160 sourcecode-zipball for kernel 3.2]

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

== Models ==
[[File:easycap.png]]

These known STK1160 based models of the video capture device are supported by the above mentioned drivers. All models do have the same USB device ID: 05e1:0408.

* Model 001 with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 48000 Hz audio (AC'97 audio)

* Model 002 with 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable and 8000 Hz audio (microphone audio)

* Model 001m with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 8000 Hz audio (microphone audio)
(Obviously this device has the board of Model 002 but the cables of Model 001)

=== Identify the audiotype of your device ===
The following shell command reports the audiorate (sampling frequency) of your STK1160 based device: (48000 = Model 001; 8000 = Model 001m or Model 002).

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.
=== Video inputs (channels) ===

From the two or four video cables on the device only one (!) can be used at the same time.
If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.

=== Usage ===

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0).

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio (get a list with this command: '''cat /proc/asound/cards''').

==== Example for mplayer ====
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:forceaudio:immediatemode=0 -ao sdl

==== More programs ====
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-16T14:56:37Z

Andlandl: dmesg easycap

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

== How to identify your device ==

When '''lsusb''' reports the following output you have an STK1160 based video capture card:

Bus 001 Device 002: ID 05e1:0408 Syntek Semiconductor Co., Ltd STK1160 Video Capture Device

== Hardware ==
On the board of this USB 2.0 video capture device there is on the front side a green LED, the STK1160 USB Bridge and a SAA7113 compatible video processing chip (silan sc8113) and on the back side a AC97 audio chip (this chip is missing on the 8000 Hz audio models of this device).

[http://easycap.blogspot.co.at/2012/07/new-driver-for-easycap-dc60-stk1160.html Additional installation instructions]

== Models ==
[[File:easycap.png]]

These known STK1160 based models of the video capture device are supported by the above mentioned drivers. All models do have the same USB device ID: 05e1:0408.

* Model 001 with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 48000 Hz audio (AC'97 audio)

* Model 002 with 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable and 8000 Hz audio (microphone audio)

* Model 001m with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 8000 Hz audio (microphone audio)
(Obviously this device has the board of Model 002 but the cables of Model 001)

=== Identify the audiotype of your device ===
The following shell command reports the audiorate (sampling frequency) of your STK1160 based device: (48000 = Model 001; 8000 = Model 001m or Model 002).

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.
=== Video inputs (channels) ===

From the two or four video cables on the device only one (!) can be used at the same time.
If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.

=== Usage ===

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0).

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio (get a list with this command: '''cat /proc/asound/cards''').

==== Example for mplayer ====
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:forceaudio:immediatemode=0 -ao sdl

==== More programs ====
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

Stk1160 based USB 2.0 video and audio capture devices

2012-08-16T14:50:42Z

Andlandl: Switch to template

This article covers all the tunerless USB 2.0 video and audio capture devices which are based on the STK1160 chip. This device is convenient for capturing from cameras, VHS-tapes, receivers ... and even for small surveillance installation (4 inputs model).

Many but not all of these devices are branded as [[Easycap]]. Althought this device is sold with different names and labels, in many forums and blogs this device is called "EasyCAP DC60".

==Overview/Features==
* USB ID 05e1:0408
* USB 2.0 interface (USB 1.1 will not work, it's too slow).
* Inputs: (Model 001) CVBS, S-VIDEO, AUDIO(L), AUDIO(R)
* Inputs: (Model 002) 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable
* Audioquality: Model 001 has AC'97 audio (48000 Hz samplerate), model 002 (and some models 001 where the AC'97 chip is missing) has mono microphone audio (8000 Hz samplerate).

===Components Used===
* Syntek STK1160 (USB video bridge)
* [http://www.silan.com.cn/english/product/ProductItemDetail.aspx?id=18&pid=20090706092630633824691909652010&c=%E8%A7%86%E9%A2%91%E7%94%B5%E8%B7%AF Silan SC8113] (Philips SAA7113 compatible video decoder)
* AC'97 audio processor (from different manufacturers. In models where this chip is missing audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)

== Models ==
[[File:easycap.png]]

These known STK1160 based models of the video capture device are supported by the above mentioned drivers. All models do have the same USB device ID: 05e1:0408.

* Model 001 with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 48000 Hz audio (AC'97 audio)

* Model 002 with 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable and 8000 Hz audio (microphone audio)

* Model 001m with input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R) and 8000 Hz audio (microphone audio)
(Obviously this device has the board of Model 002 but the cables of Model 001)

=== Identify the audiotype of your device ===
The following shell command reports the audiorate (sampling frequency) of your STK1160 based device: (48000 = Model 001; 8000 = Model 001m or Model 002).

lsusb -v -d 05e1:0408 | grep tSamFreq | sed -e "s,^.* ,,"

If you encounter audio problems while capturing you need to specify the correct audiorate of your model in the capturing program.
=== Video inputs (channels) ===

From the two or four video cables on the device only one (!) can be used at the same time.
If you want to switch through the different inputs of your card you need to start the capturing program again with the next input number.

=== Usage ===

The STK1160 device needs a USB 2.0 capable USB port. USB 1.1 will not work (it's too slow).

The driver for the STK1160 device creates a /dev/video'''N''' node and an ALSA soundcard, The different video-inputs of the device can be accessed by their inputnumber (starting at 0).

In the viewing/ capturing program (e.g. mplayer) you must specify
* the videodevicenode of the STK1160 card (/dev/video'''N'''),
* the input number of the cable where the source is plugged in,
* the TV norm of the videosource and (e.g. PAL, NTSC)
* the ALSA sounddevice if you want to capture audio (get a list with this command: '''cat /proc/asound/cards''').

==== Example for mplayer ====
Assumed that your STK1160 device is the second videodevice (the first is your webcam) and the second soundcard on your system, and that on the first CVBS input a PAL camera is plugged in and sound also comes from the STK1160 device, the mplayer command for viewing would look like this:

mplayer tv:// -tv driver=v4l2:norm=PAL:width=720:height=576:outfmt=uyvy:device=/dev/video1:input=0:\
alsa:adevice=hw.1:forceaudio:immediatemode=0 -ao sdl

==== More programs ====
These programs are known to be useful for analogue audio- and videocapturing with STK1160 based (and similar) devices.

* qv4l2 - useful for testing
* mplayer and mencoder
* [http://code.google.com/p/mtvcgui/ mtvcgui] - Python GUI for mplayer and mencoder
* VLC
* TVtime
* avconv (libav; formerly ffmpeg)
* Zoneminder - Linux surveillance suite
* Any other program which is capable of analogue video- and audiocapturing will probably work with STK1160 devices.

== Short linux driver history ==
In early 2010 [http://sourceforge.net/projects/easycapdc60/ Mike Thomas] started developing a driver for the stk1160 based video capture device which is sold as EasyCAP DC60. Since the driver (version 0.9) has been added to the staging directory of the Linux kernel in November 2011 Mike Thomas stopped his development and support for the easycapdriver.

Some people added changes in order to clean up the sourcecode. These changes didn't hardly affect the limitations (framedropping, stability) of the driver.

At the middle of 2012 [https://github.com/ezequielgarcia/stk1160-standalone Ezequiel Garcia] decided to rework the easycapdriver. He changed the drivers name to "stk1160".

In one of the next kernel releases (3.6/7) the stk1160 driver will come into mainlaine and replace the old easycapdriver.

[[File:easycap-clones.jpeg|right|250px]]Many USB video capture devices are sold as EasyCAP.

It seems that EasyCAP is not a companys or brand name, but some manufacturers use this label for at least three completly '''hardware different''' clones of this USB analogue audio- and videocapturedevice. EasyCAP devices and clones are vastly sold in onlineshops at low prices.

This article describes, how to identify the chipset of the known EasyCAP devices and if they are supported/ working in Linux.

== Common technical features of all EasyCAP devices==
[[File:Easycap.png|right|250px]]
* All the EasyCAP devices and clones need a USB 2.0 connection (USB 1.1 is too slow).
* They are tunerless but can capture analogue video up to 720x576 px (PAL) or 720x480 px (NTSC) and
* stereosound up to 48000 Hz sampling rate (or only 8000 Hz mono on some models where the ac97 chip is missing)
* Most of them have input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R).
* Some models do have 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable.

== Indentify your device before buying ==
It is hard to identify the chipset of any EasyCAP device before buying because most onlineshops (ebay, amazon) do not mention in the provided technical data the chipset of the device.
[http://www.logilink.de/showproduct/VG0001.htm Example from logilik.de where the chipset is declared]
=== Identify device using installationinstructions for Windows ===
[[File:windows-installer.png|right|150px]]If the chipset is not mentioned in device specifications on the website, one way to figure out the chipset inside the EaysCAP is to read through the installationinstructions for Windows (if provided for download).

[[File:easycap-clones.jpeg|right|200px]]Many USB video capture devices are sold as EasyCAP, but EasyCAP is not a companys or brand name.

This name is used for some completly '''hardware different''' cheap clones of this USB analogue audio- and videocapturedevice which are vastly sold in onlineshops.

This article describes, how to identify the chipset of the known EasyCAP devices and if they are supported/ working on Linux.

== Common technical features of all EasyCAP devices==
[[File:Easycap.png|right|250px]]
* All the EasyCAP devices and clones need a USB 2.0 connection (USB 1.1 is too slow).
* They can capture analogue video up to 720x576 px (PAL) or 720x480 px (NTSC) and
* stereosound up to 48000 Hz sampling rate (or only 8000 Hz mono on some models where the ac97 chip is missing)
* Most of them have input cables labelled CVBS, S-VIDEO, AUDIO(L), AUDIO(R).
* Some models do have 4 yellow input cables (CVBS) labelled 1, 2, 3, 4 and one white unlabelled audio cable.

== Indentify your device before buying ==
It is hard to identify the chipset of any EasyCAP device before buying because most onlineshops (ebay, amazon) do not mention in the provided technical data the chipset of the device.
[http://www.logilink.de/showproduct/VG0001.htm Example from logilik.de where the chipset is declared]
=== Installationinstructions for Windows ===
[[File:windows-installer.png|right|150px]]If the chipset is not mentioned in device specifications on the website, one way to figure out the chipset inside the EaysCAP is to read through the installationinstructions for Windows (if provided for download).
Screenshots of the windowsinstaller often reveal the devicename.

* STK1160 EasyCAP is in Windows: '''(Syntek) STK1160''' or '''STK1150'''
* Empia EasyCAP is in Windows: '''USB 2861 Device''' or '''EMP'''
* Somagic EasyCAP is in Windows: '''SM-USB 007''' or '''SMI Grabber Device'''
