• Common library:
  • Fix handling of onAudioSessionIdChanged in SimpleBasePlayer and ForwardingSimpleBasePlayer.
• ExoPlayer:
  • Fix race condition related to audio session id generation that could lead to an IllegalStateException with tunneling mode (#3099).
  • Fix possible app crashes when recovering from decoder errors with renderer prewarming.
  • Fix issue where video artifacts were caused by supplying initialization data when using an AV1-based Dolby Vision codec (#3153).
• Track selection:
  • Adjust track selection logic in VideoTrackInfo to resolve fallback MIME types and move HDR and codec score preferences to quality preferences (#3135).
• Extractors:
  • MP3: Ignore Xing data length if it is longer than the known stream length (#3117).
  • Fix ArrayIndexOutOfBoundsException in Mp4Extractor when FLAG_OMIT_TRACK_SAMPLE_TABLE is set and the track lacks a sync sample (stss) box.
• Audio:
  • Fix bug where audio events may be misrouted if multiple audio renderers are added to the player.
• Video:
  • Adjust logic for codec reuse at frame rate changes on API below 30 to avoid codec resets where they are not beneficial (#3120).
  • Disable forced synchronization workaround in queueSecureInputBuffer for API 31+. The workaround was an artificial bottleneck that forced decryption to run serially which prevented garbled video due to a framework issue existing prior to API 31.
• Image:
  • Fix issue in scrubbing mode where image updates would only take effect when the user "stops scrubbing" (#2815).
• Session:
  • Fix bug where ForegroundServiceStartNotAllowedException wasn't propagated across thread boundaries in case the application thread is not the main thread (#2499).
  • Fix bug where COMMAND_SEEK_TO_MEDIA_ITEM is not available in a MediaController when connecting to a platform-only session that supports seeking to other items but no playlist modifications.
  • Fix issue where MediaController can't set media items on platform media sessions that don't allow PREPARE_FROM actions.
  • Fix bug where own process wasn't marked with Controller.isTrusted() on API 27 or before when connecting via platform controllers.
• HLS extension:
  • Fix a bug where an ArrayIndexOutOfBoundsException is thrown during stream fallback if the track selection is a subset of the available tracks (#3161).
  • Fix an issue where the initialization segment was not carried over across media playlist updates if the #EXT-X-MAP tag was not repeated in subsequent updates (#3105).
• DASH extension:
  • Fix crash in SampleQueue when seeking into a chunk that is currently being canceled.
