RTSP source mp4 FLV streaming

Today, after many months of research and work, i managed to develop a working solution for the following task:

There is an IP camera which acts as an mp4 video RTSP server on a remote location. The requirement, the live stream of the camera has to be embedded into a webpage as flash video source. Unfortunately the previous solution incorporated an unconverted mp4 stream, many disconnections, Darwin Streaming Server, VideoLan software. We had to create a special VideoLan installation for the clients to install the browser plugin as default and set up the RTSP over TCP as default.

I have read not so far away in a mailing list of Motion video surveillance system, that someone has managed to create an RTSP video stream converted to a /dev/video0 source using openRTSP and ffmpeg. Here came the idea, and i created a working prototype of the solution of this task with the help of openRTSP, ffmpeg, and ffserver. The solution is FLV streaming from an RTSP server as source.

Ofcourse i ran into problems, so my first try to feed a converted stream of flv into ffserver failed. The cause of the problem was me. The ffserver only likes FFM as his input format.

The right command which creates a usable source to ffserver is:

openRTSP -v -c -t rtsp://rtsp.server.com/ | \
ffmpeg -r 5 -f m4v -i - http://127.0.0.1:8090/feed1.ffm

The basic config in ffserver.conf is:

Port 8090
BindAddress 0.0.0.0
MaxClients 200
MaxBandwidth 20000
CustomLog /var/log/flvserver/access.log

<Feed feed1.ffm>
File /tmp/feed1.ffm
FileMaxSize 512000
ACL allow 127.0.0.1
</Feed>

<Stream rtspsource.flv>
Feed feed1.ffm
VideoBitRate 1024
VideoBufferSize 128
Format flv
VideoSize 352x288
VideoFrameRate 5
VideoQMin  3
VideoQMax  3
NoAudio
</Stream>
