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(())
}
