HTTP Live Streaming


This test checks if browsers/devices support the Apple HLS protocol version 3, specifically the following capabilities:

  • Playback of a basic HLS stream (single bitrate).
  • Playback of an adaptive HLS stream (3 bitrates).
  • Playback of an AES encrypted HLS stream.
  • Exposing of 608 captions embedded in the HLS stream.
  • Broadcasting of ID3 metadata embedded in the HLS stream.

See the Pantos draft for more information.

  1. HLS is built into the Android OS since version 3. It has severe issues on Ice Cream Sandwich (4.0). Subsequent Android releases improved upon HLS, but even Lollipop (5.0) has issues with e.g. accurate seeking and updating of controls.
