Thanks for the reply!

What I'd like, ideally, is to be able to do this:

ffmpeg -i file1 {map video 0, audio 1 to output video 0, audio 1} -i 
file2 {map video 1, audio 3 to output video 0, audio 1} -i file3 { map 
video x, audio y to output video 0, audio 1 } outfile

Basically, combining files, for each specifying the video and audio 
stream that will create an output file with one video and one audio 
stream based on those.

Is it possible? If it is, what should the "-map" contain?

Thanks!
