Hi Jose,
do you manage to stream a video encoded in another codec than h264
over RTP? And how do you do it, can you please post some ffserver
config and instructions how to call ffmpeg?
I just managed to fix the ffmpeg-error by filling the ffserver feed
with rawvideo, given by my webcam.
1.) ffserverwebcam.config, preparing ffserver to stream rawvideo over RTP:
Port 8090
BindAddress 0.0.0.0
RTSPPort 5004
RTSPBindAddress 0.0.0.0
MaxClients 10
MaxBandwidth 40000
NoDaemon
<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 500M # just for testing, i try to stream rawvideo so make
room for it
ACL allow localhost
ACL allow 127.0.0.1
ACL allow 192.168.0.0 192.168.255.255
</Feed>
<stream webcamvideo.avi>
Feed feed1.ffm
Format rtp
VideoCodec rawvideo
VideoFrameRate 10
VideoBufferSize 40
VideoBitRate 36864
VideoSize 640x480
VideoGopSize 10
NoAudio
AVOptionVideo flags +global_header
</Stream>
<Stream stat.html>
Format status
ACL allow localhost
ACL allow 127.0.0.1
ACL allow 192.168.0.0 192.168.255.255
</Stream>
<Redirect index.html>
URL http://www.ffmpeg.org/
</Redirect>
Then I start ffserver with:
ffserver -d -f ffserverwebcam.conf
2.) Now the feed of the ffserver is filled by ffmpeg which gives the
rawvideo of my webcam to it:
ffmpeg -f video4linux2 -s 640x480 -r 10 -i /dev/video0 -an -vcodec
rawvideo http://localhost:8090/feed1.ffm
It works, ffmpeg is continously giving frames to the feed of ffserver.
It writes continously similiar output to these to the console:
frame= 196 fps= 10 q=0.0 size= 88508kB time=19.60 bitrate=36992.7kbits/s dup=
frame= 202 fps= 10 q=0.0 size= 91216kB time=20.20 bitrate=36992.2kbits/s dup=
frame= 208 fps= 10 q=0.0 size= 93928kB time=20.80 bitrate=36993.2kbits/s dup=
etc.
3.) Now I try to watch the stream.
3.1) At first I ve tried it with ffplay:
ffplay rtsp://localhost:5004/webcamvideo.avi
It fails with the output:

3.2) Ive tried it with mplayer too:
mplayer rtsp://localhost:5004/webcamvideo.avi
It fails, too, with the output:

mplayer: could not connect to socket
mplayer: No such file or directory

Exiting... (End of file)
It comes to the end of file.. Looking a bit strange to me. Something
is wrong in the ffserver config, I think. Please look to the config
"<stream webcamvideo.avi>". I say here ".avi". Does this mean that
ffserver uses automatically the container AVI to put the rawvideo
stream in? Does it really use AVI or just naming the rtp stramfile
webcamvideo.avi?
Whats your experience with streaming video (if realtimevideo like
webcam video or a file video) over RTP?
Please post your experiences..
Thanks,
Ali Ayhan D.
