[MPlayer-users] RTSP - mencoder - ffmpeg - ffserver

[sid]

Hi evryone.

I'm trying to connect my ip-cam to motion.

Due to a bandwidth problem i have to stream via RTSP a H.264 video,
but motion do not support H.264 so i have to convert the stream to
MJPEG and stream it back to motion again.

My idea was to use mencoder to read and convert the stream than pipe
the output (through a FIFO) to ffmpeg/ffserver to stream it back to
motion.

These are the commands i've been using :

 mencoder rtsp://usr:pwd@10.0.1.115:554/axis-media/media.amp -ovc lavc
-lavcopts vcodec=mjpeg -o pipe1

and

ffmpeg -an -i pipe1 http://localhost:8090/feed1.ffm

The problem with this solution is that i can see the framerate of the
mencoder output increasing till 5 fps (or similar) than ffmpeg exits
giving the error :"pipe1: Unknown format".

Here is the complete output:

$mencoder rtsp://usr:pwd@10.0.1.115:554/axis-media/media.amp -ovc lavc
-lavcopts vcodec=mjpeg -o pipe1

I've tryed to move to conversion from mencoder to ffmpeg with similar
result and i've tryed to use openRTSP with ffmpeg with no result, so
i'm totally stucked.

The only solutions I'm still trying is to use mencoder and vloopback
to copy the converted stream to /dev/video0 and than read with motion
from /dev/video1.

What you think about the solution to this problem?

Thanks a lot.
