ExoPlayer's default behavior is to use a multiplication of target segment by a coefficient (3,5).
This coefficient (and this behavior) cannot be customized without using a custom HlsPlaylistTracker right now.
New behavior is to wait 15 seconds before throwing a PlaylistStuckException.
This should improve a lot HLS live streaming on (very) low-latency livestreams with buffering issues, especially on YouTube with their HLS manifests.
-Fixed play queue playlist desynchronization caused by media source manager window loading expansion on sublist prior to current item.
-Fixed failed media source not treated as ready for playback.
-Added sync buttons on live streams to allow seeking to live edge.
-Added custom cache key for extractor sources to allow more persistent reuse.
-Refactored player data source factories into own class and separating live and non-live data sources.
