Ran this (had to put the first command in the background and wait 10s
before starting ffmpeg).  It looked like it was working.  Figured that
it is a timing issue (ffmpeg starting too early).  Well..... it
finished, and I had no output file.  Nothing. So, I looked and noticed
this from ffmpeg:

ffmpeg version 0.4.9-pre1, build 4754, Copyright (c) 2000-2004 Fabrice

I'm sure I compiled ffmpeg correctly.
