The main purpose is the streaming rather than sending video or audio information. MP4 files can be used to store additional data such as text information, subtitles and still images while MPEG format can’t do this, anyhow the processing of data into MPEG-4 part 14 requires the use of private streams such as the use of hint tracks to include the information.
