[streaming] Re: how to create a RTSP stream

[Ed _]

Hi Victor,

Thanks

I am actually trying to get a stream to be the input to a darwin server.

I want to read from an RTSP stream - transcode it and make it the input to a 
darwin server to which different RTSP clients (Quick Time/WMP) can connect.

You seem to understand how to configure this - would appreciate your help on 
this.

For starters - I have everything on one box - IP_ADDR

I have an rtsp stream - rtsp://IP_ADDR:8554

I can view the stream using vlc - #vlc rtsp://IP_ADDR:8554

Next I try to modify the orig stream and stream it out again.

vlc -vvv rtsp://IP_ADDR:8554 --sout 
"rtp{dst=IP_ADDR,port=1234,sdp=rtsp://IP_ADDR:8080/test.sdp}"

I get the following error -

Any Idea what I am missing?
