[MPlayer-users] Problems with audio video sync.

[Michael Raizman]

Hi all!

    I have a huge problem with audio/video sync in MPlayer. Here is a 
set-up-box EPIA-M and RedHat9 on it. I compiled the mplayer with faad2 
and live support and try to run the RSTP stream (video mp4v (MPEG-4) 
audio mp4a (AAC)). There is a big delay beetwen audio and video - 
approximatly 2-3 sec. I tried differnt method to avoid it :
-autosync; -mc; -framedrop and etc. Please help. May anybody have an idea.

This is the log:
