I need some kind of audio test mpeg-2 stream. I'd like something that would do a 'front left... front right... center...' etc.
It's hard to find tools to do this stuff, since it's nearly all proprietary. I actually have a few test AC-3 streams, but multiplexing one with some video to make the dvd player happy seems impossible with my current tools.
If I ever write dvd authoring software for linux, remind me to name it 'FUMPAA', a Fine Utility for Making Pieces of Animated Art :)
