M3U8 Parser

A Rust crate for parsing and creating M3U8 version 7 files for HTTP Live Streaming (HLS), as specified by RFC 8216.

[!IMPORTANT] This project is under active development. Features and APIs may change.

Features

• Parse M3U8 playlists from strings, files, or readers
• Generate M3U8 playlists and write them to strings, files, or writers
• Support for all tags specified in RFC 8216, including:
  • Basic Tags (e.g., #EXTM3U, #EXT-X-VERSION)
  • Media Segment Tags (e.g., #EXTINF, #EXT-X-BYTERANGE)
  • Media Playlist Tags (e.g., #EXT-X-TARGETDURATION, #EXT-X-MEDIA-SEQUENCE)
  • Master Playlist Tags (e.g., #EXT-X-STREAM-INF, #EXT-X-MEDIA)
  • Encryption Tags (e.g., #EXT-X-KEY, #EXT-X-SESSION-KEY)
  • Date Range Tags (e.g., #EXT-X-DATERANGE)

Installation

Usage

Parsing a Playlist

use m3u8_parser::m3u8::playlist::Playlist;

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let data = r#"
    #EXTM3U
    #EXT-X-VERSION:7
    #EXT-X-TARGETDURATION:6
    #EXTINF:5.009,
    https://media.example.com/first.ts
    #EXTINF:5.009,
    https://media.example.com/second.ts
    #EXTINF:3.003,
    https://media.example.com/third.ts
    #EXT-X-ENDLIST
    "#;

  let playlist = Playlist::from_reader(data.as_bytes())?;
  println!("{:?}", playlist);
  Ok(())
}

Creating a Playlist

use m3u8_parser::m3u8::playlist::builder::PlaylistBuilder;

fn main() -> Result<(), Box<dyn std::error::Error>> {
  let playlist = PlaylistBuilder::new()
          .extm3u()
          .version(7)
          .target_duration(6)
          .extinf(5.009, None)
          .uri("https://media.example.com/first.ts".to_string())
          .extinf(5.009, None)
          .uri("https://media.example.com/second.ts".to_string())
          .extinf(3.003, None)
          .uri("https://media.example.com/third.ts".to_string())
          .end_list()
          .build()?;

  playlist.write_to_file("playlist.m3u8")?;
  Ok(())
}
