Difficulty configuring video4linux v4l
 

Hello,

I hope somebody can help me with this problem:

I have set up my camcorder through my ATI TV Wonder Pro tv tuner card... this is not how others set up their webcams. But this setup was detected by tvtime, xawtv, and skype as a video source through Composite2 (in fact, skype is even video-conferencing-ready). They seem to be using the device /dev/video0.

However, those programs which depend on gstreamer-properties, ekiga, camorama, cheese, etc. can not seem to recognize this as a video source. They all depend on v4l. How can I tell v4l to use Composite2 from my tv-tuner... the device /dev/video0 as a video source?

Thanks for the help

There's v4l2 and v4l.

v4l-info should list what your capabilities are.
v4lctl to change things.
v4l-conf for some of that too.

Not all drivers are well done so you might need to run tvtime or something to setup the device in a usable mode, then run the app you want to run on it. (q) to exit works most of the time.

Kernel module wise you might need to enable / load the v4l1-compat module and friends to enable v4l (pre-v4l2) support.

My camcorder can work as a 640x480 webcam via the uvcvideo module over USB (sanyo FH1). luvcview to setup the settings, then most other things work after that. Also make sure that your user is in the video group.
