Basic Engine Features

Broadcast programme is scheduled via Dashboard/Steering. Possibility to mix / switch between 3 different audio sources:

  1. Play playlists from filesystem (audio files are provided via Tank)
  2. Play external audio streams
  3. Play live audio

Other:

  • Playlists should be played without any delay, even when the individual items are extremely short e.g. Jingles, sound effects (compare Radio Freistadt)
  • Include RDS information for UKW/terrestrial broadcasts (this is solved by a separate Ticket https://gitlab.servus.at/aura/engine/-/issues/22)
  • Ability to broadcast to IceCast streaming server
  • Configurable Audio quality
  • Support 4 or more Stereo-In channels (e.g. Studio 1, Studio 2, BBC, Satellite, Tuner)
  • Extensive logging

Open Sub-Tasks:

  • File System Scheduling and correct Playout, Transitioning, Engine Core refactoring
  • Fix sidecase with parallel playout.
  • Fix Volume issues when switching between Playlist Entries
  • Check if all cases for "end of schedule" and "end of entry" are working as expected.
  • Configurable Logger with Log Levels. Update Logs with adequate Log Level.
  • Test scheduling with Analog IN Entries, multiple Analog INs, correct scheduling and play-out in the mix
  • Test scheduling with Stream Entries, multiple Streams, correct scheduling and play-out in the mix
  • Stream output, Check settings for IceCast connectivity, Test and possible fixes
  • Test very short and very long filesystem entries and correct timings with those. Most likely this requires another major refactoring to allow pre-scheduling. Currently unsure how to get this done with Liquidsoap playlists. Possibly use of a LQS Server Function could help + another type of queue.
