FFMPEG - demuxing?

[pantson]

Hi

GBPVR is working excently... love the proggy.

I have a bunch of files now in MPEG2 format and I want to start to archive these off. I am trying to use FFMPEG (comes with the GBPVR).

When I convert using ffmpeg (no matter what the output format is) the sound and picture come out of sync. I beleive the file needs demux first. Heres the command line....
ffmpeg.exe -i %input% -vcodec mpeg4 -vtag xvid -b 1200 -qmax 10 -ab 64 -ar 48000 -acodec mp3 "%output%"

Am I missing a demux flag or something?

I know its not supported by GBPVR.. but i am wondering if anyone can help (or have any dos progs that demux mpeg2 streams)

Have the same problem.
Picture and sound out of sync after using transcode going from dvr-ms to xvid.

try using ProjectX, it can fix timeline problems while demuxing.
