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
Can you hexdump the first 1 kB and send it to the list? I need to see the AVI header to guess what's wrong. You can probably fix it by changing the fourcc in the AVI file to 'MJPG'.
