Audio is lagging behind Video

Bug Description

Binary package hint: mplayer

In Feisty I noticed an audio lag when playing back divx/xivd movies (audio is mp3 compressed).
This hasn't been the case in edgy/dapper/breezy ...
If I watch the movies in totem/xine everything is fine -- so I must expect that the avi-files are not broken.

A temporary workaround is to use "-ac ffmp3" as command-line option.
see bug #85751 https://bugs.launchpad.net/ubuntu/+source/mplayer/+bug/85751

I also noticed, when pressing + or -, in order to shift the audio in time, mplayer never can go to +/- 0 ms and is always stuck at -48ms.
In gmplayer I even cannot change the lag.

Further observations:

This happens only with acidrip encoded films (=mencoder + xvid + mp3)
When I use transcode everything is ok.

So I think this could be an encoding bug in mencoder.

Other opinions?

Can you check if this was still occurring for you with the mplayer 1.0~rc2 release? One of the issues it address is a/v sync on streams.

This bug was fixed in the package mplayer - 2:1.0~rc3+svn20090426-1ubuntu6

---------------
mplayer (2:1.0~rc3+svn20090426-1ubuntu6) karmic; urgency=low

  [ Andres Mejia ]
  * Enable VDPAU support by including vdpau headers in deb packaging.

  [ Reinhard Tartler ]
  * sort build dependencies alphabetically
  * avoid using tabs - prefer space instead
  * reenable 22disable-xscreensaver.patch. The patch does work, but you
    need to have the mouse cursor INSIDE the window
  * don't build-depend on libmad, the internal mp3lib library is superiour
    for most cases these days, according to upstream. LP: #111025, #163382
  * add clarifications to the libgsm license.
  * install the TOOLS/midentify.sh script LP: #333828
