gotcha.  I just know that other programs can deal with raw video just
fine, so maybe they're using some kind of file header or something.  no
biggie.

ok, yeah, I see that now.  toolame defaults to 44.1

Is the audio sample rate in the nuv header?  If so, I can pull it out
with my script.  Otherwise, we'd need something like a streams.info file
to go into the fifodir that would contain all of the relevant
information about the stream.
