What is m3u8 File? Complete Analysis
In-depth understanding of m3u8 file format, structure and application scenarios
m3u8 File Overview
M3U8 is a text-based playlist file format using UTF-8 encoding. It is an extension of the M3U format, specifically designed for HTTP Live Streaming (HLS) protocol. M3U8 files contain metadata information of media files, guiding the player on how to retrieve and play video content.
File Structure Analysis
A typical m3u8 file contains the following:
#EXTM3U
# HLS protocol version number
#EXT-X-VERSION:3
# Maximum duration of each media segment
#EXT-X-TARGETDURATION:10
# Media sequence number
#EXT-X-MEDIA-SEQUENCE:0
# Duration of media segment
#EXTINF:10.0,
segment0.ts
#EXTINF:10.0,
segment1.ts
#EXTINF:10.0,
segment2.ts
# End of playlist marker
#EXT-X-ENDLIST
Key Tag Descriptions
- #EXTM3U - File header, indicating this is an M3U playlist
- #EXT-X-VERSION - HLS protocol version number
- #EXT-X-TARGETDURATION - Maximum duration of each media segment
- #EXTINF - Duration of media segment
- #EXT-X-ENDLIST - End of playlist marker
Application Scenarios
Real-time streaming media transmission
On-demand video playback

HLS Protocol Details
In-depth understanding of HTTP Live Streaming technology principles and working mechanism
What is HLS?
HTTP Live Streaming (HLS) is a streaming media network transmission protocol based on HTTP proposed by Apple. It divides the entire stream into small HTTP-based files to download, only downloading a few at a time. When the media stream is playing, the client can select the appropriate video stream for the current network rate based on the current network conditions.
HLS Workflow
-
Encoding and Segmentation
Encoder encodes audio and video media into H.264 video and AAC/MP3 audio, and segments them into a series of small files
-
Index Creation
Create m3u8 playlist file containing index information of all media files
-
File Distribution
Distribute media files and playlist through standard HTTP server
-
Client Playback
Client software downloads these small files in sequence and plays them continuously, supporting adaptive bitrate switching
HLS Technical Advantages
Based on HTTP, strong firewall penetration capability
Intelligently adapts to different network environments
Supports multiple devices and platforms
Uses standard HTTP cache, reduces server pressure
HLS vs Other Streaming Protocols
- HLS - Apple-led, best compatibility, slightly higher latency
- MPEG-DASH - International standard, feature-rich, good compatibility
- RTMP - Adobe-led, low latency, but requires Flash support
- WebRTC - Real-time communication, lowest latency, suitable for live interaction
