Since MPEG-4 is a container format, MP4 files may contain any number of audio, video, and even subtitle streams, making it impossible to determine the type of streams in an MP4 file based on its filename extension alone. In response, Apple Inc. started using and popularizing the M4A file extension using for audio-only MP4 files.

MPEG-4 Part 14 is most commonly used to store digital audio and digital video streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still drm-remover. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. The official filename extension for MPEG-4 Part 14 files is .MP4, thus the container format is often referred to simply as MP4. Devices that play MP4 files are referred to as MP4 players.
