I open two VLC media player for testing to play h264 files throung rtsp/rtp.One is streaming server by choosing rtp protocol.The order one is for receiving the streaming by chooseing UDP/RTP.
I have tested vlc-0.8.4a and vlc-0.8.6a.When i used vlc-0.8.4a,the client just can receive the first frame then the error messages is like below.

The computer environment i have tested are p3-700 and p4-1.5.They both can't play the files successfully.
ps. the server command line is ":sout=#duplicate{dst=std{access=rtp,mux=ts,dst=127.0.0.1:1234}}"
Any suggestion to solve this will be appreciate.
