[FFmpeg-devel] [PATCH] bug with multitracks file

[Larbi Joubala]

Ok but can we fix the issue without appliying our patch but integrate 
this patch in the code? Our patch is simple. It just increases the 
"MAX_STREAMS" of avformat.h to a big value (90 in our case) in order to 
support multitracks file(>20 streams) with which we work(MP4 or ASF).
