[streaming] RTSP and choppy sound

[Kristian Larsson]

Hello all,

I am trying to view an divx encoded movie over the
Internet by using RTSP VoD. Everything is working 
out except for the audio, it is very choppy, I can
make out a word in every ten or perhaps twenty
seconds. Looking at "Stream and Media" info I can see
the audio "Lost buffers" counter increasing like
crazy. About 75% of all audio buffers are lost.
This is over the Internet, but not very far,
within the same city so latency is ~2ms. Bandwidth
is 100Mbps in both ends.
Video is working flawlessly.

I have also tried viewing the VoD with mplayer
which results in quite crappy video - vlc does a
much better job with the video. But audio works
fine in mplayer.

If I try ffplay I get good looking video with good
audio though it runs out of sync after a while
(which apparently is a known bug in ffplay).

Where should I begin troubleshooting? Any tips or
hints are highly appreciated.

Thank you,
   Kristian.
