which makes ftyp atom always written, 'qt ' is good for MOV files (according to FCP), 'mp42' is conformed to what ffmpeg produce for mp4 files.
Maybe "isom" should be used for ftyp? If "mp42" or "mp41" is used, there should be a IOD and a correct BIFS/OD Track in the mp4 file. Richard
I got here a sample produced by FCP which does not contain 'iods' atom. I consider FCP being the reference, so 'iods' is not needed when 'mp42' ftyp is used.
