[MPlayer-users] A/V sync problem with rc2

[Bohdan Linda]

Hello,

I am using mencoder to downsample avi files for my PMP. My config for
mencoder is attached bellow.

The problem is this worked perfectly for version MPlayer 1.0rc1-4.2.3, but from
rc2 up to  dev-SVN-r26779-4.2.3 the problem is, that during seeking in mplayer
audio get restarted from beginning, but video continues well (PMP just
crashes).

Adding ovf=lavf=yes seems helping a bit, but audio is shifted heavily, so no
fix. Please note, that almost every video has frame reduction, but maybe it is
not related. For more info I have paste mplayer output for both working and non
working version. Note that file although named the same is recoded from
original with mencoder of given version

Removing noodml=yes does not fix the problem.

Please can you advise, what is causing the problem?

Thank you,
Bohdan
