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.


  • 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.
  • Capturing is possible from only one input at a time!

Components Used

The components of the different EasyCAP labeled devices are mentioned in the "Known Easycap devices" section below.

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. Example from logilik.de where the chipset is declared

Identify device using installation instructions for Windows

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

Known Easycap devices

STK1160 EasyCAP

For the stk1160 based EasyCAPs exists another article on this wiki with further information.

It is assumed that the stk1160 based "EasyCAP DC60" ist the "originally" EasyCAP device. This device is sold in different varieties (models) and even under different names like: EzCap, LogiLink, Mumbi, Weltbild, and some more.

Components Used

  • Syntek STK1160 (USB video bridge)
  • Silan SC8113 or GM7113 (Philips SAA7113 compatible video decoder)
  • AC'97 audio processor (In the 4 inputs model this chip is missing. Audio capturing is done by the STK1160 chips built-in ADC for mono microphone audio recording.)


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

Making it work

STK1160 based devices are supported (video and audio) under Linux by the easycap kernel module (kernel 2.6.38 and later) and further on by the stk1160 kernel module (kernel 3.7). More information on this wiki: Stk1160

Audio support

More information on this wiki: Stk1160#Drivers

Empia EasyCAP

The Empia EasyCAP is based on the EM2860 chip from Empia.

Components Used

  • Empia EM2860 (EM2861 ?) (USB video bridge)
  • Silan SC8113 (Philips SAA7113 compatible video decoder)
  • AC'97 audio processor


# lsusb
Bus XXX Device XXX: ID eb1a:2861 eMPIA Technology, Inc.

Making it work

EM2860 (EM2861) based devices are supported in Linux by the em28xx kernle module. More information on this wiki: Em28xx_devices

Audio support

The em28xx kernel module should create a Em28xx Audio ALSA soundcard which can be used for sound capturing.

Somagic EasyCAP

The Somagic EasyCAP is based on the SMI-2021 chip from Somagic. It needs a firmware for operation.

Components Used

  • Somagic SMI-2021CBE (USB video bridge)
  • SAA7113 compatible video decoder
  • Cirrus Logic 5340-CZZ audio processor


# lsusb
Bus XXX Device XXX: ID 1c88:0007 Somagic, Inc. 
and after loading the firmware
# lsusb
Bus XXX Device XXX: ID 1c88:003c Somagic, Inc. or Bus XXX Device XXX: ID 1c88:003f Somagic, Inc.

Making it work

For SMI-2021 based devices exists a proceeding Linux-driver project: easycap-somagic-linux

More information on this wiki: Somagic

Audio support

Audio support is provided by the easycap-somagic-linux driver at an unknown stage.


This EasyCAP is based on a single UTV007 labeled chip.

This device is sold as "USB video capture QS702" from SHENZHEN FUSHICAI ELECTRONIC CO.,LTD

lsusb reports

  • Manufacturer: Fushicai
  • Product: usbtv007

Components Used

  • Single chip: UTV007 A614231.1 1136L1BK
  • Inscriptions on the board: FSC VIDEO DVR

Bus XXX Device XXX: ID 1b71:3002 

Full lsusb -v

Making it work

Linux kernel driver, enable CONFIG_VIDEO_USBTV: https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/media/usb/usbtv

  • From 3.11 ("Linux for Workgroups") on: Supports NTSC, Composite input
  • From 3.12 : S-Video input, Fixed deinterlacing, Throw corrupted frames away
  • From 3.13 (rc5) : PAL support (poor video quality)
  • In works: Controls (brightness, ...)

Also, a very experimental (for testing purposes only) userspace driver is available on github: http://github.com/memeruiz/usbtv007

  • Currently doesn't do anything beyond what kernel driver does
  • Written using Python libusb1 and v4l bindings
  • Requires v4l loopback
  • Could be useful for easy protocol testing, prototyping
Audio support

A work in progress on the audio support can be found at: https://github.com/simon3z/usbtv

Status: tested and working for composite input (48Khz 2ch 16bit).

Work needed

  • Testing and fixing of eventual bugs is very welcome!
  • Audio is currently not supported on the last Linux kernel. Audio is working with the Windows driver (tested on Windows 2000 with the XP driver not on a virtualized computer with a playstation PSX for the video and audio inputs with the software "honestech HD DVR 2.5").

The Windows driver shipped with the device was for another model. Here's the correct one: http://v3.sk/~lkundrak/usbtv/usbtv-wxp32.zip

Slides from talk describing setup for reverse-engineering what does the hardware do are available: http://www.slideshare.net/LubomirRintel/usb-reversing
