[FFmpeg-user] Can't stream using rtsp ... Could not write header for output file #0

Fri Sep 25 19:24:18 CEST 2015

Hello.

I'm trying to re stream an rtsp stream using ffmpeg.

I have no problem getting the original rtsp stream and write it to a file,
although I can't get ffmpeg to stream this video again using rtsp.

Everything seems fine until the point ffmpeg gets stuck and only stops if I
press CTRL-C, at this point I get an error message saying:

"Could not write header for output file #0 (incorrect codec parameters ?):
Immediate exit requested"

Here's the command line I'm using :

"ffmpeg.exe -v debug -stats -i rtsp://192.168.1.40/rus -vcodec copy -an -f
rtsp -c copy rstp://localhost:554/video"

I can't get it to work.

Any ideas what I'm doing wrong?

Here's what I get on screen:

ffmpeg.exe -v debug -stats -i rtsp://192.168.1.40/rus -vcodec copy -an -f
rtsp -c copy rstp://localhost:554/video
