Multitrack Audio Video Game Compression

[AtariV8]

I currently use Bink (RadTools) to compress video for game development and I'm usually not to happy with the results. I've been looking into Divx or WebM in order to conduct some testing but run into a wall when dealing with the number of audio tracks I need in order to run 5.1 with localization (Currently 27 tracks, swapping L-R-C with different languages). I believe Vorbis and AAC both can handle a good number of tracks but I have yet to find an encoder that will allow me to add anything more than 6 (5.1). After encoding, the game engine must also be able to select and play certain tracks in different combinations. Is there another solution (legal and able to be licensed) or am I stuck with Bink.

There is a difference between tracks (known as streams) and channels. Most audio formats will only support up to 2, 6 or possibly 8 channels but encoders may not support actually support this many. Whereas any good container format will support your 27 tracks (plus the video). I think Ogg will support his many, MKV will, MP4 will.

Since you posted in the H.264 you are clearly looking for people to tell you to use H.264, so I am.

What encoder do you suggest using?
