[MPlayer-users] Startup latency and AV sync problems with RTSP stream from VLC through SDP file

[Selwyn Tang]

Hi all,

I am trying to playback an rtsp stream (udp multicast) of mpeg2 ts from 
a vlc server described in an sdp file. But there are problems with the 
startup latency and AV sync.

Mplayer holds for a very long time in:
     PROBING UP TO 2000000, PROG: 0
before playing back. Then the A/V sync are seriously out of mind, 
cumulating too many audio or video packets in the buffer, and eventually 
causing mplayer to quit itself.

To work around the problems, I tried starting two mplayer processes, one 
with "-nosound" and the other "-novideo". The result was acceptable, but 
there were frequent broken macroblocks.

Does mplayer support such rtsp stream from vlc? Is there a better way to 
playback the stream?
