#2070(undetermined:new): Handling Multichannel BINK

#2070: Handling Multichannel BINK -------------------------------------+------------------------------------- Reporter: DJX | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- 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.
