I have a number of Mjpeg avi files recorded using the
windows based software that comes with a Matrox Marvel
card. I'm trying to use mjpeg tools to do some
transcoding of these to Mpeg2. However none of the
tools seem to be able to read the frames of these
files. Lavplay says "error playing a frame" for every
frame and displays a window with assorted color bars.
Similar results occur for the other utilities. The
output of lavinfo is below, you can see a warning
message about the JPEG format. For reference, these
files can be played back fine using either Quicktime 5
or the windows based Matrox video player.
++ WARN: [lavinfo] Input file favmistake.avi is not in
JPEG 4:2:2 or 4:2:0 format
