Originally Mpeg-4 was an instance of more general ISO mp4 specification, which in turn comes from QuickTime media file format. First Mpeg-4 specifications and formats were published back in 2001, Version 1, then replaced by Version 2 in 2003, which persists now. Mpeg-4 is still 4, but version of its format is number 2. Currently video files saved as Mp4 format must include so-called Atom that describes video and helps media player properly count-down frames in video stream, etc. It's like ID-tags of an mp3 file, although mpeg-4 cannot exist without Atom file, so it's always included in the beginning or end of the file. But it needs whole file to process the video and post all the info, making mp4 useless for streaming in big videos or live videos. Big videos are simply split into many many little pieces, called usually Transport Mpeg stream, while live videos are also supplied as little files, all in all, always including small Atom versions in every file, that's why stream size is usually 10-15% more than a file on your desktop, because of the excessive atoms everywhere...
