Transcode - Video and Audio not in sync
I have a problem in that I am trying to re-code some videos from avi (WMV3) to MPEG-2.
However, when I re mplex them, the video is anything up to a second ahead of the audio. I think that is because, on the original files, the sound starts and then the video fades in from black. I don't know if the problem occurs when creating the *.m2v and *.mpa files, or when multiplexing them back together, but it seems to make little difference whether I use mplex or tcmplex for the task.
I have tried using both the mpeg and the mpeg2enc/mp2enc filters in transcode, I get the same result either way.
avidemux does not work because it does not work with WMV formats above WMV2, and TMPGenc (windows program) cannot read the format either.
A typical line I have tried is:
transcode -i filename.avi -x mplayer,mplayer -y mpeg,mpeg -E 44100 -Fs,3 -b 128 -Z 480x576 -o TEMP
mplex -f 4 -o filename.mpg TEMP.m2v TEMP.mpa
Has anyone else experienced this problem and is there another way?
