Hi josé,
Ive tried out your config from your post
http://lists.mplayerhq.hu/pipermail/ffserver-user/2009-November/000112.html
and managed, too, that ffmpeg is doings its work
1.) So i execute the ffserver with this configfile:

2.) And I run ffmpeg this way - filling the feed with my webcam data
which ffmpeg is encoding to h264, thats cool ;)
ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -an -vcodec
libx264 -vpre default -bf 5 http://localhost:8090/feed1.ffm
Its running continously with the output:

The 4 lines after "Press [q] to stop encoding" seems strange to me,
especially "VBV underflow (frame 0, -931 bits)".

ffplay rtsp://localhost:5004/webcamvideo

De facto)
Players are complaining about missing information about the video. At
this point we just can guess whats going wrong.
First try of guessing:
ffmpeg is craping the headerfile - see 2.) where it throws an error.
But isnt it the job of ffserver to provide information about the
stream to the client-players? So whats exactly wrong there..
Second try:
Server provides a header which others dont understand? Would be
strange, cause (their own) ffplay doesnt work neither and is
complaining about missing parameters.
Third try:
Server provides no header to the client-players.
Iam asking myself if its still a setup problem or a problem in the
sourcecode. Can someone confirm that it is or not a problem of the
sourcecode?
