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

I just made a mistake when writing the email.
The command line I used was:
ffmpeg.exe -v debug -stats -i rtsp://192.168.1.40/rus -vcodec copy -an -f rtsp -c copy rtsp://localhost:554/video
There's no RSTP, it's always RTSP what I'm using.

...would appear to be related. Check your command line parameters. The order of
options is significant.
However, the errors may be misleading - you do seem to have an error in your
command line. RTSP and RSTP are two different protocols:

Try correcting the url for the output stream first.
Having said all that, I'm not an expert - some of the dev's do watch this list and have a
much better idea of how these things work, so if this doesn't help, hopefully someone
else can. :)
