also tryed to sniff the traffic. but i'm realy new to this.
use wireshark to look what VLC send:

that works.


And with mmpeg it looks like this:

Request: OPTIONS rtsp://192.168.178.5:554/live/av0?user=admin RTSP/1.0\r\n
Method: OPTIONS
URL: rtsp://192.168.178.5:554/live/av0?user=admin

Accept: application/sdp\r\n
Cseq: 2\r\n

\r\n

and it don't work.



so looks like that "Cseq" is the problem.
but have no idea how to fix that.
