Sync problem - replace ms mp3 codec ??

[burnix]

Hello. I'm not new on divx, vcd, or dvd encoding, but i have problem, and after numerous search on this forum ans other site i dont have the solution.

The problem was, when i encode in mpeg (vcd or dvd) an avi file (divx+mp3) sometime i get delay on audio. The avi sync was good.

I've tested most solution (tmpgenc, cce, mainconcept, cce+avisynth), but allways the same problem.

I arrive at the conclusion that the ms codec or dshow codecs are bad and cannot interpret correctly the audio flux.

So my question is : how to replace the ms mp3 codec or correct it ???

Thanks in advance for all.

try demuxing audio with virtual dub
process audio with besweet
process avi with avisynth/cce
remux with ifoedit/tmpeg-mpeg tools...

I know this technique. But i have a very large number of file to convert (100) so i want to know why there is this problem.

I use nandub to extract the mp3 file, re-encode with winlame, and remux with nandub. I can do mp3 -> wav and encode video and audio separatly.

If i resume, i know a solution but i want to know where is the core problem.

Thanks for your response.

Finally i have found the solution.

I just have tu use in my avisynth script the function "directshowsource" instead of "avisource".

Then audio and video was sync.

Thanks for your help.
