| Notes | |
| [1] | a) All ftyp's may be used as "major" or "compatible" brands, except as noted in [5] and [6] below. b) ftyp's may be case sensitive. Recent editions this table have been updated to reflect the defined or common usage, but apps which read ftyps would be well advised to read them in a case insensitive fashion. c) All ftyp's must contain 4 characters. If three characters are shown in the table, a trailing blank (i.e. a space character; ASCII 0x20) is implied. Similarly, if only two characters are shown, two trailing blanks are implied. For example, "qt" is really "qt " - note the two trailing spaces. |
| [2] | "Reg'd" means the ftyp is registered here with the official authority for such registrations, MP4REG. |
| [3] | These ftyp's are included in MPLAYER source code and the Multimedia Wiki, but these 3GPP releases apparently don't exist. |
| [4] | Found in some GPAC samples (but not the source code); no further information is available. Apparently doesn't exist. |
| [5] | 'isom' is seen used as a major brand, though it is currently prohibited by ISO/IEC 14496-12 sec 6.3 paragraph 2. |
| [6] | Like 'isom', use of 'iso2' as a major brand is specifically prohibited by ISO/IEC 14496-12 sec 6.3 paragraph 2. |
| [7] | Nero Recode now uses these ftyp codes as major brands, while also listing them as compatible brands. Previously, Nero used 'avc1' as the major brand for their AVC encoded files, and MP41 (or MP42?) for the others. |
| [8] | Nero uses this ftyp code as a compatible brand for AAC encoded audio files. Such files also included 'isom' as an additional compatible designation, and 'mp42' as the major brand. |
| [9] | Apple / iTunes / iPod audio files with major brand 'M4P ' are DRM (copy) protected. Audio files with major brand 'M4A ' may or may not be DRM protected. iPod video files appear to use 'M4V ' regardless of whether or not they are DRM protected. |
| [10] | The MIME type these entries should be "audio/3gpp" for audio-only files (i.e. no video or "timed text") |
| [11] | 'avc1' means the file uses ISO/IEC format extensions originally created for H.264/MPEG-4 AVC support. Does not necessarily imply the video was encoded with H.264/MPEG-4 AVC, however. |
