AVIs with many audio streams

[alexnoe]

How many audio streams may there be in an avi, if it should be replayed with directshow?

If I make standard AVIs, 5 works fine (didn't try more), but for Open-DML files over 1 GB, only up to 3 audio streams are accepted. More than 3 lead to an "unknown file format", regardless wether audio is ac3, mp3 or pcm.

Is this a DirectShow bug or are my files corrupt?

Oh how the mighty have fallen...

From a mod down to a lowly Junior Member. ;-)

Haven't programmed with directshow before, but I read a similiar thread somewhere, which leads me to think it is a Directshow problem.

Note that AVI-Mux GUI is completely based on "ReadFile" and "WriteFile" for the whole file input and output (OK, seeking is sometimes also necessary...), and it does not use any DirectShow-, VCM or other buggy crap.

If DirectShow is the problem, then it is the AVI file reader of DirectShow which is crappy.

Found the bug!

You must split the standard indices into several pieces (one per 15000 frames seems to work) when adding more than 3 audio streams to an open-dml file larger than 1 GB!
