Hello everybody.
I'm trying to backup a DVD provided with 3 audio streams, spanish, german and english. My problem is that, when I put all three tracks into the AVI (e.g. using AVIMUX), the resulting file doen't work fine. If I change the stream during playback (with MicroDVD), there is audio/video desynchronization. If I move to another point of the movie, the desynchronization appears again! It works only if I start the film in one stream and don't touch anything!!
Note that the files I use as streams are already compressed mp3 files. Could AVIMUX work if I multiplex uncompressed WAVs? It would take a huge amount of space in HD, anyway...
I have tried with Nandub. It works fine, but only with 2 tracks. And I don't want to leave the third one out!!
I have also tried to put a WAV header to the mp3 file (using wavemp3( and do the multiplex with graphedit, using the directshow filter AVI/WAF File Source to input the video and audio streams to the AVI Mux filter. I got the same desynchronizations with MicroDVD, and also using graph files and having the Windows Media Player read them to play the different streams.
Curiously, the Graphedit method worked perfect again when I only used 2 streams. No desynchronizations at all. Just perfect.
NOTE: in the AVIMux filter, there are some switches you can play around with. They all seem to have a lot to do with audio synchronization, but everything is useless. When you put three streams, it just doesn't work.
I can't seem to get it right!! I would give up and let the second and third streams out of the AVI, having MicroDVD use them to substitute the main audio stream. but it also leads to desynchronizations (and strange, loud noises).
Can somebody tell me, whether there is a limit to the number of audio streams an AVI file can carry? Did anybody got more than 2 streams in an AVI without desynchronizations?
Please, somebody help me. I have spent a lot of time with this issue, and I'm feeling terribly frustrated.
