[FFmpeg-user] 8 channel audio codec in mp4

[Mark Himsley]

Is there an audio codec I can use to encode 8 channels of audio into one 
stream in an mp4 container?

Preferably without an LFE channel filter.
Preferably that can be opened in Premier Pro.

The motivation is to make proxy-viewing / offline-editing files of 8 
channel rushes material.

I've made the suggestion of 8 streams of mono aac, which works nicely in 
FCP but apparently Premier Pro is a bit sluggish with.

Thanks :-)
