.
...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: 

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

Rodney.
