Well.. yeah I call ffmpeg CVS with -vd /dev/video0 (and the rest to
make it stream to my server) just like 4.8.0 and it simply quits
telling me it can't find the video device... even before outputing
anything worth mentioning here ;)

Hmm... thx for the reassurance, I'll try and compile it with these options!

I don't, it was just an assumption because I can't get my webcam to
work since a long time in CVS history (april may I believe).

I'll keep you posted about the test results!
