MPEG-4 files with audio and video generally use the standard .mp4 extension. Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of unprotected content. MPEG-4 files with audio streams encrypted by FairPlay digital rights management as were sold through the iTunes Store use the .m4p extension.
At present, only files that are in the Windows Media (.wmv) file format may be added to your playlist. Other file types such as .mpg, .mpeg, and .avi cannot be added to the playlist.

MPEG-4 is a group of international standards for the compression of digital audio and visual data, multimedia systems, and file storage formats. It was originally introduced in late 1998 as a group of audio and video coding formats and related technology agreed upon by the ISO/IEC Moving Picture Experts Group (MPEG) (ISO/IEC JTC 1/SC29/WG11) under the formal standard ISO/IEC 14496 – Coding ...
Clementine v1.2, an audio player with a media library and online radio. The basic feature set of media players are a seek bar, a timer with the current and total playback time, playback controls (play, pause, previous, next, stop), playlists, a "repeat" mode, and a "shuffle" (or "random") mode for curiosity and to facilitate searching long timelines of files.
Audio file icons of various formats. An audio file format is a file format for storing digital audio data on a computer system. The bit layout of the audio data (excluding metadata) is called the audio coding format and can be uncompressed, or compressed to reduce the file size, often using lossy compression.
The 'Music' category is merely a guideline on commercialized uses of a particular format, not a technical assessment of its capabilities. For example, MP3 and AAC dominate the personal audio market in terms of market share, though many other formats are comparably well suited to fill this role from a purely technical standpoint.
MPEG-4 Audio includes a system for handling a diverse group of audio formats in a uniform manner. Each format is assigned a unique Audio Object Type to represent it. [18] [19] Object Type is used to distinguish between different coding methods. It directly determines the MPEG-4 tool subset required to decode a specific object.
All modern browsers will play video (Theora and WebM) and audio (Vorbis and MP3) files from Wikipedia, no modifications needed. On older iOS, iPadOS, and macOS devices, software decoding will be used. This might be a bit slow compared to what you are used to on such devices. Internet Explorer is NOT supported.
