[FFmpeg-user] Re-Stream to RTSP

[Dennis F]

Hi,
I am trying to use FFmpeg to re-stream an RTP stream to RTSP.
 
It never starts streaming and I have to issue a Ctrl-C.
 
I'm not sure what's wrong but I consistently get this error:
Could not write header for output file #0 (incorrect codec parameters ?): Errorn umber -5 occurred
 
Here is my uncut console output:
.\ffmpeg -re -i rtp://239.255.1.1:59000 -f rtsp -rtsp_transport tcp -rtsp_flags listen -c copy -muxdelay 0.1 rtsp://172.16.1.56:554/live
