M3U8 vs Other Formats

M3U8 vs MP4

MP4 is the most common video container format, suitable for storage and download playback. M3U8 is a playlist index file used for streaming. An MP4 file is a complete video file containing video, audio, and metadata; M3U8 points to a series of small video segment files.

In terms of playback, MP4 can be played after complete download from local or server, supporting random seek to any position; M3U8 plays while downloading, and seeking requires loading the corresponding segment. In live streaming scenarios, M3U8 has a natural advantage as it supports dynamic playlist updates.

M3U8 vs FLV

FLV (Flash Video) was once the dominant web video format developed by Adobe. With the phase-out of Flash technology, FLV has gradually become obsolete. In contrast, M3U8 is based on the open HLS standard, requires no proprietary plugins, is entirely HTML5-based, and offers better cross-platform compatibility and security.

M3U8 vs DASH

DASH (Dynamic Adaptive Streaming over HTTP) is another mainstream adaptive streaming protocol developed by MPEG. HLS (M3U8) was developed by Apple with native Safari and iOS support; DASH has better support on Android and Chrome. Both are functionally similar, supporting adaptive bitrate, DRM protection, and low-latency modes.

Choosing between HLS and DASH mainly depends on the target platform. If Apple device support is needed, HLS is essential; if primarily targeting Android and Web users, DASH may be more appropriate.

M3U8 vs RTMP

RTMP (Real-Time Messaging Protocol) is Adobe's real-time messaging protocol mainly used for live streaming publishing. RTMP features extremely low latency (1-3 seconds), suitable for real-time scenarios like gaming streams. However, RTMP requires dedicated streaming servers and doesn't support adaptive bitrate.

M3U8/HLS is mainly used for playback, with relatively higher latency (10-30 seconds, reducible to 2-5 seconds with LL-HLS), but offers better scalability and compatibility.
