Well... I try to do something similar of what you did... except that I have a camera witch I don't know what format returns. From vlc I get mpeg-ts container, mpeg1, 2600kbps. My problem is that any protocol I use the ffmpeg just hangs... I tried them all. That's why I put the mplayer between.
I'll try http again... still I don't think it will magically work :). P.S. Is not a consolation... I'm getting near 2 months also and it can be really frustrating. 2011/3/28 Anthony Brown <a...@bsbc.nb.ca> > On 11-03-28 05:20 PM, Victor Petrescu wrote: > >> That's the first version I tried and it just hangs.

Thus, in theory, ffmpeg doesn't have to transcode, either (though > in practice it does since ffserver has no way of knowing that the incoming > stream is already in the right format).
