It would be interesting to test with ffmpeg as well. Your other programs
only display the video; encoding is much more hard ;)

Well, it seems that I'm the only maintainer of the v4l feature in vls...
I know that vls is not very tolerant, I haven't spent enough time to
master completely the ffmpeg lib & v4l api capabilities. Providing that
I am also involved in other time-consuming activities around videolan,
I won't be able to test all the webcams of the market, and I prefer to
stabilize and provide a solid production vls that works with few webcam
and acquiring boards, rather than trying to support the latest webcam
drivers. However, I am definitely willing to help people testing vls &
other webcams, explaining the vls code or testing remotely on someone's
hardware... whatever.

By the way, I have worked a bit around the audio bugs; the current cvs
should deal much better with v4l devices. This may be a good starting
point for the future works.
