How to join AVI files with multiple audio streams

[V@no]

Hello.

I'm using the following commandline to join multiple avi files into one without reencoding:

mencoder.exe -oac copy -ovc copy -mc 0 -noskip -o finished_name.avi first_part.avi second_part.avi

It works great, however when an avi contains two or more audio streams, it copies all of the streams (I could tell by filesize), but fails write it into header, so players can only see the first stream.

Can someone please help me with this?

Thank you.

Welcome V@no

Even if those multiple streams are copied they will be ignored ... avi in general when joining should contain the same type and number of streams.

If an avi has 5 audio streams ... then for all the others you would extract their audio and generate additional audio streams ... each needs to match format and frequency found in the multiple audio avi ... then after they have been joined you won't have any problems.

Thank you for reply and welcome

Both .avi files have the same structure, same number of streams. It used to be one file then was split in half with virtualdubmod (I think) so it would fit on a cd
