Making it Work

Should be supported under linux when commit

"[media] em28xx: fix Terratec Grabby AC97 codec detection"

gets mainlined.

Note: For unknown reason, to get the sound you should either:

  • load the em28xx-alsa module *BEFORE* plugin the Grabby
# modprobe em28xx-alsa
  • or connect it, wait, disconnect it and reconnect it

Typical mplayer commandline is:

mplayer tv:// -tv driver=v4l2:width=720:height=576:device=/dev/video1:input=0:fps=25:norm=SECAM-L:alsa:adevice=hw.2:audiorate=48000:forceaudio:amode=1:immediatemode=0

Firmware

No firmware is required.

Status

On a Debian Stretch with a 4.7.8-1 kernel, the Grabby v3 works with ffplay and qv4l2, but the picture quality is not very good, sometimes some lines or the whole display "jumps". And with some video sources captured on Linux, there is more noise than signal while those same video sources display ok with the Windows drivers.

Audacity can capture the sound properly but qv4l2 sound output stutters a lot and keeps displaying the following errors :

ALSA lib pcm.c:8251:(snd_pcm_recover) underrun occurred
ALSA lib pcm.c:8251:(snd_pcm_recover) overrun occurred


Firmware

The driver loads v4l-cx231xx-avcore-01.fw into the Grabby.

The windows drivers CD also contains a firmware with the following MD5 hash : a9f8f5d901a7fb42f552e1ee6384f3bb

Drivers

The Grabby v3 use the following kernel module : cx231xx
