Not a patch review, just a note that one can do this with ffmpeg/ffprobe 
and basic *nix tools.

To check for moof,

      ffmpeg -i in.mp4 -v 56 2>&1 | grep -e type:'moof'

To see if moov precedes mdat

      ffmpeg -i in.mp4 -v 56 2>&1 | grep -e "type:'moov'" -e 
"type:'mdat'" | head -1 | grep moov
