Cache (Offline Playback)



This Add-On provides developers a way to observe how much of the player is visible.

Key advantage of using this integration:

  • Enables users to pre-cache (parts of) a given source, which can then be immediately played from cache during playback. This approach drastically reduces startup times, removes download delays and can serve as a guard for viewer experience over flaky connections.


API Extensions

From version 2.26.0 onward.
