Fragmented MP4 (fMP4) vs. Normal MP4
fmp4 is a streaming media format based on MPEG-4 Part 12.
The video/audio metadata information and data of fmp4 are stored in each moof and mdat, which is a streaming encapsulation format.
fmp4 can be combined with Media Source Extension (MSE) for HTML5 live broadcast.
fmp4 is composed of a series of fragments. If the server supports byte-range requests, we can request some fragments separately and combine with MSE for streaming
