This brings up the issue that mplayer doesn't support MJPEG A (markers)
or B (no markers) which both use key frames and inter frames for
temporal compression. Therefore calling the key frame only JPEG codec
mplayer uses MJPEG is incorrect and misleading. In quicktime it's more
correctly called "Photo - JPEG" for mplayer just drop the "M" and call
it JPEG!
