Comment (by cehoyos):

 Replying to [comment:2 muken]:
 > MP4 file format itself has no support of 'raw ' and 'twos'.

 So what does "Sample Entry Codes Registered to ISO" means then?

 > These identifiers are defined in Motion JPEG 2000 file format (15444-3).
 > You need add the JP2 Signature Box at the start of file and add 'mjp2'
 brand into the  File Type Box if muxing them.

 But we don't do that currently for other codecs that we allow in isom or
 do I misunderstand?
