Summary of the bug:
I have a BINK video that has three audio streams. I believe this is
because it is used in a surround sound environment. I would like to
purpose a change to the way FFmpeg handles these types of files. In this
case, they should all be mixed together to produce the correct audio
output. Currently, on a two channel system, it is missing a lot of the
audio.
Additionally, as a work around, I tried the "amerge" filter but it does
not allow for this type of conversion because the file has more then two
audio streams.
FFmpeg & FFplay should be considered here.
How to reproduce:
