Multiple audio : Merge started

[zakk]

While copy mode is OK, reencoded audio is still unsynchronized (200ms shift at the beginning, 400 at the end of video).
Any idea why reencoding audio would ADD audio frames and increase delay ? (same result with mkvextraction and audacity reencoding).

with a specific audio codec or any of them ?

[zakk]

I tried every audio codec accepted with mkv or mp4v2 containers.
Result is always audio 400ms too early.

Funny thing, I put the A-Marker a few P-Frame later (instead of 0:00:00, by the way no more I-frames ?) and this time I got 600ms too late in my copy/mp3/mkv.

(all tests with first 5mn of video)

Confirmed

Any workaround ?

[mean]

Maybe better with last patch, win32 build in progress

Just encodeda 8GB file: result OK! 
Looks like Avidemux 2.6 has become my ultimate tool! Thanks!

Can we have some kind of safeguard of copying/saving more then two audio tracks into avi container.
When saving MPEG-TS with more then 2 audio streams in to avi container.Avidemux shuts down unexpected without leaving crash file or anything.
Perhaps check if more then 2 audio streams when saving in to avi container: warning pop-up saying so and preventing avidemux to process (saving this video) and opening the Audio  tracks configuration window?

I'm cleaning up the avi muxer

[Jan Gruuthuse]

thank you as always, looking forward.

Again, does someone know if the mp3 encoder is set to "stereo" or "joint stereo" ? Thanks.
