I'm trying to stream h264 video from my Logitech C920 webcam.
I'm using such ffserver.conf:
Port 8099
NoDaemon
BindAddress 0.0.0.0
RTSPPort 5004
RTSPBindAddress 0.0.0.0
MaxClients 10
MaxBandwidth 10000

VideoCodec libx264

And I'm starting ffmpeg like this:
./ffmpeg -f video4linux2 -s 640x480 -r 15 -re -i /dev/video0 -an -vcodec libx264 -bf 5 http://localhost:8099/feed1.ffm
But in the output there is:

Any suggestion how not to do transcoding and stream the video directly?
Best Answer
Actually I've succeed with streaming of h264 video with ffmpeg. I was able to do this with help from ffmpeg-user list, especially from Carl Eugen Hoyos, author of this patch:
Actual command I've used:
But I wasn't able to get rid of transcoding, so I switched to vlc (and succeed).
