[MPlayer-dev-eng] [PATCH] Fix Quicktime A/V-Delay Sync Issues

[Felix Buenemann]

Hi,

this patch fixes problems with Quicktime files that use different
length/starting times for audio/video tracks. This is most often used
when video was prepended by a short ad.

The MOVs Edit-List then looks like this (simplified):
#1 video: start=0.0 lenght=300.0
#2 audio: start=4.0 length=296.0

The attached patch uses MPlayers-AV-Sync delay to fix this up. The patch
was made against CVS of 06-03-10, because that's the only build that
works on my intel mac up to now, but it applies fine against current svn.
Because of the way MPlayer's a/v sync works (by speeding up/slowing down
video), this option works best with -framedrop enabled.

I've tested this on about 100 quicktime files wih and without described
edit-list structure, most of them taken from www.movie-list.com classics
section. Also this works with both MPlayer and MEncoder.

Best Regards,
     Atmos
