Thanks Roger - I'd definitely be willing to give it a try. Any idea what
I'd be piping from (and into ffmpeg)? Also, could you (or anybody else)
clarify whether or not ffmpeg can be reading a stream of audio or video
from a file that is concurrently being written to (by some other process)?
Thanks again!
