Death of a dwarf.
While the only official file extension defined by the standard is .mp4, various file extensions are commonly used to indicate intended content:
* Audio-only MP4 files generally have a .m4a extension.
o MP4 files with audio streams encrypted by FairPlay Digital Rights Management as sold through the iTunes Store use the .m4p extension.
o Audio book and podcast files, which also contain metadata including chapter markers, images, and hyperlinks, can use the extension .m4a, but more commonly use the .m4b extension. An m4a audio file does not "bookmark" (remember the last listening spot) on an iPod, whereas m4b extension files do. Users can rename mp4 m4a file extensions m4b to activate this and faster listen iPod features.
* MP4 files with audio and video generally use the .mp4 and .m4v extensions, occasionally .mp4v. To add to confusion sometimes raw MPEG-4 Visual bitstreams are named .m4v.
* Mobile phones use 3GP, a simplified version of MPEG-4 Part 12 (a.k.a MPEG-4/JPEG2000 ISO Base Media file format, MPEG-4 Part 14 is a derivative of the standard from ISO Base file format too), with the .3gp and .3g2 extensions. These files also store non-MPEG-4 data (H.263, AMR, TX3G).
The common, but non-standard use of the extensions .m4a and .m4v is due to the popularity of Apple's iPod and the iTunes Store.
