MENCODER skips frames when dealing with MPEG-2 audio ...

Basically PAL DVD compliant MPEG-2 streams are encoded with audio codec mp2 (MPEG 1 - Layer 2), this is the standard, but mencoder cannot handle it without glitches, it skips 5-6 frames at the beginning and this causes the whole audio stream of the conversion will have positive or negative latency and this causes a/v desync.

https://forum.mediacoderhq.com/viewtopic.php?t=9247
Does any one have any recommendations on how to get MEncoder (as video source) to deinterlace with Yadif Mode 1 and still stay in sync with the audio? I am aware that Yadif Mode 1 doublerate frame, but when I increase the frame rate to 59.940 (original source is 29.97), my film length goes from the original 23:33 to 20:34 and the audio is ...

If 'Skipping frame!' or '1 duplicate frame(s)!' warnings occur repeatedly, and the resultant audio grows out of sync (as if one is faster) then try tweaking the source framerate. 'skipping frame' means there's too many frames coming in, so try a lower fps. 'duplicate frame' means there isn't enough frames coming in to satisfy the outgoing framerate, so try a higher …

MEncoder - LinuxTVWiki

What is new is that the latest mencoder version usefully reports "Skipping frame!" once a second during recording. The workaround is to set the framerate explicitly with -fps 30000/1001. In addition, in the most recent version of mencoder, the default codec for mpeg is FMP4, while it used to be DIVX. To reset it to DIVX, use the -ffourcc DIVX ...

Audio out of sync - General Support / Questions - MCEBuddy
https://discussion.mcebuddy2x.com/t/audio-out-of-sync/2938
<encoder>-AudioDelay=xxx/auto/skip (v2.1.2-2.2.18, 2.2.19+) This parameter is set for each encoder type, e.g. ffmpeg, mencoder or handbrake. When xxx is set to skip then it tells MCEBuddy to skip auto correction of audio delay (sync). This is useful for some file formats such as AVI where audio gets skewed on auto correction.
[MPlayer-users] Audio sync problem with mencoder
https://groups.google.com/g/mplayer_users/c/2kb7bEHOMkQ
I've been a happy user of mencoder for many years, mainly for ripping DVDs. Something changed recently and it stopped working: specifically, the audio is no longer in sync with video. I first started having this problem with Ubuntu's binary package a couple of weeks ago; it's still happening with the current binary from Ubuntu 11.10 (version
