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.

Description	MKV file format is the most convenient type of file format where you can add a large sum of data, such as videos, audios, texts, and various images as well. It is basically a RAW format which you can later flip and separate on the basis of needed data tracks.
Technical details	Every file whether it is video, audio, subtitle or image it will be stored into a separate data line. It is a lot similar to the MP4 or AVI format although when users are packaging an MKV file they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format therefore, the users need to use specialized media players who can support the MKV format such as VLC media player.
