This caught me out today, so just as an FYI to anyone else this might affect, the change to enable ‘optimal' huffman coding by default since Sunday 9th April, does cause playback to break in Quicktime Player 7 on macOS. Since Quicktime Player 7 is very old now this is understandable, but for anyone that needs to maintain compatibility, add '-huffman default' to your mjpeg command.
