Audio lags video for avi movie

[William Salibrici]

Hi Tim,
Thank you for your reply.
I did as you suggested and yes it fixed the problem!
Playback is fine now using my play pipeline as well as the windows media player.
Any further insight as to why audio was lagging?
At first I was using mulawenc but I removed it to further reduce audio leg latency.
If anything, I would have expected video to be lagging due to the greater computational overhead in the video leg.
Perhaps one of the elements I’m using is not reporting latency correctly – I don’t know.
Regards,

Bill

Hi Bill,

 Here are my two questions for the second record pipeline where audio lags video:


  1.  What is causing the audio to lag the video?
  2.  What would be the best way to add a fixed latency to the video leg in the recording pipeline so that audio and video are in sync for playback? My customer application requires the standard windows media player for playback so I can’t tweak the playback properties.

I’m using GStreamer 1.6.4 with your windows pre-built binaries.



Try adding a videorate element before the video encoder and an audiorate element before the audio encoder or muxer (if you mux raw audio), to see if that makes a difference.



Cheers
