• Core Library:
  • Deprecate SimpleExoPlayer. All functionality has been moved to ExoPlayer instead. ExoPlayer.Builder can be used instead of SimpleExoPlayer.Builder.
  • Add track selection methods to the Player interface, for example, Player.getCurrentTracksInfo and Player.setTrackSelectionParameters. These methods can be used instead of directly accessing the track selector.
  • Enable MediaCodec asynchronous queueing by default on devices with API level >= 31. Add methods in DefaultMediaCodecRendererFactory and DefaultRenderersFactory to force enable or force disable asynchronous queueing (6348).
  • Remove final dependency on jcenter().
  • Fix mediaMetadata being reset when media is repeated (#9458).
  • Adjust ExoPlayer MediaMetadata update priority, such that values input through the MediaItem.MediaMetadata are used above media derived values.
  • Move com.google.android.exoplayer2.device.DeviceInfo to com.google.android.exoplayer2.DeviceInfo.
  • Move com.google.android.exoplayer2.drm.DecryptionException to com.google.android.exoplayer2.decoder.CryptoException.
  • Move com.google.android.exoplayer2.upstream.cache.CachedRegionTracker to com.google.android.exoplayer2.upstream.CachedRegionTracker.
  • Move Player.addListener(EventListener) and Player.removeListener(EventListener) out of Player into subclasses.
• Android 12 compatibility:
  • Keep DownloadService started and in the foreground whilst waiting for requirements to be met on Android 12. This is necessary due to new foreground service launch restrictions. DownloadService.getScheduler will not be called on Android 12 devices.
  • Disable platform transcoding when playing content URIs on Android 12.
  • Add ExoPlayer.setVideoChangeFrameRateStrategy to allow disabling of calls from the player to Surface.setFrameRate. This is useful for applications wanting to call Surface.setFrameRate directly from application code with Android 12's Surface.CHANGE_FRAME_RATE_ALWAYS.
  • Upgrade the WorkManager extension to depend on androidx.work:work-runtime:2.7.0. Earlier versions of work-runtime
    are not compatible with apps targeting Android 12, and will crash with an IllegalArgumentException when creating PendingIntents (#9181).
• Video:
  • Fix bug in MediaCodecVideoRenderer that resulted in re-using a released Surface when playing without an app-provided Surface (#9476).
• DRM:
  • Log an error (instead of throwing IllegalStateException) when calling DefaultDrmSession#release() on a fully released session
    (#9392).
• UI:
  • SubtitleView no longer implements TextOutput. SubtitleView implements Player.Listener, so can be registered to a player with Player.addListener.
  • Fix initial timestamp display in PlayerControlView (#9524).
  • Fix capitalization of languages in the track selector (#9452).
• Extractors:
  • MP4: Correctly handle HEVC tracks with pixel aspect ratios other than 1.
  • MP4: Add support for Dolby TrueHD (only for unfragmented streams) (#9496).
  • MP4: Avoid throwing ArrayIndexOutOfBoundsException when parsing invalid colr boxes produced by some device cameras (#9332).
  • MP4: Parse HDR static metadata from the clli and mdcv boxes.
  • TS: Correctly handle HEVC tracks with pixel aspect ratios other than 1.
  • TS: Map stream type 0x80 to H262 (#9472).
• Downloads and caching:
  • Modify DownloadService behavior when DownloadService.getScheduler returns null, or returns a Scheduler that does not support the requirements for downloads to continue. In both cases, DownloadService will now remain started and in the foreground whilst waiting for requirements to be met.
  • Modify DownloadService behavior when running on Android 12 and above. See the "Android 12 compatibility" section above.
• RTSP:
  • Support RFC4566 SDP attribute field grammar (#9430).
• DASH:
  • Populate Format.sampleMimeType, width and height for image AdaptationSet elements (#9500).
• HLS:
  • Fix rounding error in HLS playlists (#9575).
  • Fix NoSuchElementException thrown when an HLS manifest declares #EXT-X-RENDITION-REPORT at the beginning of the playlist (#9592).
• RTMP extension:
  • Upgrade to io.antmedia:rtmp_client, which does not rely on jcenter() (#9591).
• MediaSession extension:
  • Rename MediaSessionConnector.QueueNavigator#onCurrentWindowIndexChanged to onCurrentMediaItemIndexChanged.
• Transformer:
  • Avoid sending a duplicate timestamp to the encoder with the end of stream buffer.
• Remove deprecated symbols:
  • Remove Renderer.VIDEO_SCALING_MODE_* constants. Use identically named constants in C instead.
  • Remove C.MSG_* constants. Use identically named constants in Renderer instead, except for C.MSG_SET_SURFACE, which is replaced with Renderer.MSG_SET_VIDEO_OUTPUT.
  • Remove DeviceListener. Use Player.Listener instead.
  • Remove CacheDataSourceFactory. Use CacheDataSource.Factory instead.
  • Remove CacheDataSinkFactory. Use CacheDataSink.Factory instead.
  • Remove FileDataSourceFactory. Use FileDataSource.Factory instead.
  • Remove SimpleExoPlayer.addMetadataOutput and removeMetadataOutput. Use Player.addListener and Player.Listener instead.
  • Remove SimpleExoPlayer.addAudioListener, removeAudioListener and AudioListener. Use Player.addListener and Player.Listener instead.
  • Remove SimpleExoPlayer.addVideoListener, removeVideoListener and VideoListener. Use Player.addListener and Player.Listener instead.
  • Remove DefaultHttpDataSourceFactory. Use DefaultHttpDataSource.Factory instead.
  • Remove SingleSampleMediaSource.createMediaSource(Uri, Format, long). Use SingleSampleMediaSource.createMediaSource(MediaItem.Subtitle, long) instead.
  • Remove HttpDataSource.Factory.getDefaultRequestProperties. Use HttpDataSource.Factory.setDefaultRequestProperties instead.
  • Remove GvrAudioProcessor and the GVR extension, which has been deprecated since 2.11.0.
  • Remove DownloadService.onDownloadChanged and DownloadService.onDownloadRemoved. Instead, use
    DownloadManager.addListener to register a listener directly to the DownloadManager returned through DownloadService.getDownloadManager.
  • Remove Player.getCurrentStaticMetadata, Player.Listener.onStaticMetadataChanged and
    Player.EVENT_STATIC_METADATA_CHANGED. Use Player.getMediaMetadata, Player.Listener.onMediaMetadataChanged and
    Player.EVENT_MEDIA_METADATA_CHANGED for convenient access to structured metadata, or access the raw static metadata directly from the TrackSelection#getFormat().
  • Remove ControlDispatcher and DefaultControlDispatcher. Operations can be customized by using a ForwardingPlayer, or when configuring the player (for example by using ExoPlayer.Builder.setSeekBackIncrementMs).
