There is a new release of the m3u8 gem available that includes support for EXT-X-MEDIA attributes. This extends the library to support features such as subtitles, closed captions, and alternate audio/video in master playlists. Several fixes and improvements have also been included from contributors recently and it is nice to see there is some interest in the project. EXT-X-MEDIA is handled through the new MediaItem class: hash = { type: 'AUDIO', group_id: 'audio-lo', language: 'fre', assoc_language: 'spoken', name: 'Francais', autoselect: true, default: false, forced: true, uri: 'frelo/prog_index.

I just released a new version of my m3u8 gem, this new version provides parsing of m3u8 playlists used in HTTP Live Streaming (HLS). It represents a significant refactoring since the original scope of the project was limited to only generation of playlists. You can now read a playlist into the newly extended object model, modify or add segments/child playlists, and generate a new m3u8 output file. There is a new items array made up of either PlaylistItem instances for master playlists or SegmentItem instances for regular playlists containing MPEG transport stream files (MPEG-TS).

m3u8 is a ruby gem facilitates the generation of m3u8 playlists for HTTP Live Streaming (HLS). You can use this to serve up playlists from a rails application for the integration of authentication and other customizations, while serving the actual MPEG transport stream files (.ts) from a CDN. You can also use m3u8 to generate playlist files as part of an encoding / production pipeline. Creating a master playlist for adaptive bitrate streaming is very straightforward.
