There are some MPEGs at
http://www.aaroninjapan.com/ddrvideos.html that were
taken with a digital camera. The video is 320x240
MJPEG with a mono audio stream.
Cinelerra drastically misinterprets the audio. It
looks like a burst of noise every 2 seconds.
I'm playing around with this one right now (it's the
first listed on the page):
Is there something wrong with the header, or is there a
bug in cinelerra?
