  • Core library:
    • Verify correct thread usage in SimpleExoPlayer by default. Opt-out is still possible until the next major release using setThrowsWhenUsingWrongThread(false) (#4463).
    • Add Player.getCurrentStaticMetadata and EventListener.onStaticMetadataChanged to expose static metadata belonging to the currently playing stream (#7266).
    • Add PlayerMessage.setLooper and deprecate PlayerMessage.setHandler.
    • Add option to MergingMediaSource to clip the durations of all sources to have the same length (#8422).
    • Remove Player.setVideoDecoderOutputBufferRenderer from Player API. Use setVideoSurfaceView and clearVideoSurfaceView instead.
    • Default SingleSampleMediaSource.treatLoadErrorsAsEndOfStream to true so that errors loading external subtitle files do not cause playback to fail (#8430). A warning will be logged by SingleSampleMediaPeriod whenever a load error is treated as though the end of the stream has been reached.
    • Time out on release to prevent ANRs if an underlying platform call is stuck (#4352).
    • Time out when detaching a surface to prevent ANRs if the underlying platform call is stuck (#5887).
    • Fix bug where AnalyticsListener callbacks could arrive in the wrong order (#8048).
  • Media transformation:
    • Add a new transformer module for converting media streams. The initially available transformations are changing the container format, removing tracks, and slow motion flattening.
  • Low latency live streaming:
    • Support low-latency DASH (also known as ULL-CMAF) and Apple's low-latency HLS extension.
    • Add LiveConfiguration to MediaItem to define live offset and playback speed adjustment parameters. The same parameters can be set on DefaultMediaSourceFactory to apply for all MediaItems.
    • Add LivePlaybackSpeedControl to control playback speed adjustments during live playbacks. Such adjustments allow the player to stay close to the live offset. DefaultLivePlaybackSpeedControl is provided as a default implementation.
    • Add targetLiveOffsetUs parameter to LoadControl.shouldStartPlayback.
  • Extractors:
    • Populate codecs string for H.264/AVC in MP4, Matroska and FLV streams to allow decoder capability checks based on codec profile and level (#8393).
    • Populate codecs string for H.265/HEVC in MP4, Matroska and MPEG-TS streams to allow decoder capability checks based on codec profile and level (#8393).
    • Add support for playing JPEG motion photos (#5405).
    • Handle sample size mismatches between raw audio stsd information and stsz fixed sample size in MP4 extractors.
    • Fix Vorbis private codec data parsing in the Matroska extractor (#8496).
  • Track selection:
    • Move Player.getTrackSelector to the ExoPlayer interface.
    • Move the mutable parts of TrackSelection into an ExoTrackSelection subclass.
    • Allow parallel adaptation of video and audio (#5111).
    • Simplify enabling tunneling with DefaultTrackSelector. ParametersBuilder.setTunnelingAudioSessionId has been replaced with ParametersBuilder.setTunnelingEnabled. The player's audio session ID will be used, and so a tunneling specific ID is no longer needed.
    • Add additional configuration parameters to DefaultTrackSelector. DefaultTrackSelector.ParametersBuilder now includes:
      • setPreferredVideoMimeType, setPreferredVideoMimeTypes, setPreferredAudioMimeType and setPreferredAudioMimeTypes for specifying preferred video and audio MIME type(s) (#8320).
      • setPreferredAudioLanguages and setPreferredTextLanguages for specifying multiple preferred audio and text languages.
      • setPreferredAudioRoleFlags for specifying preferred audio role flags.
    • Forward Timeline and MediaPeriodId to TrackSelection.Factory.
  • DASH:
    • Support low-latency DASH playback (availabilityTimeOffset and ServiceDescription tags) (#4904).
    • Improve logic for determining whether to refresh the manifest when a chunk load error occurs in a live streams that contains EMSG data (#8408).
  • HLS:
    • Support playlist delta updates, blocking playlist reloads and rendition reports.
    • Support low-latency HLS playback (EXT-X-PART and preload hints) (#5011).
  • UI:
    • Improve StyledPlayerControlView button animations.
    • Miscellaneous fixes for StyledPlayerControlView in minimal mode.
  • DRM:
    • Fix playback failure when switching from PlayReady protected content to Widevine or Clearkey protected content in a playlist.
    • Add ExoMediaDrm.KeyRequest.getRequestType (#7847).
    • Drop key and provision responses if DefaultDrmSession is released while waiting for the response. This prevents harmless log messages of the form: IllegalStateException: sending message to a Handler on a dead thread (#8328).
    • Allow apps to fully customize DRM behaviour for each MediaItem by passing a DrmSessionManagerProvider to MediaSourceFactory (#8466).
  • Analytics:
    • Add an onEvents callback to Player.EventListener and AnalyticsListener. When one or more player states change simultaneously, onEvents is called once after all of the callbacks associated with the individual state changes.
    • Pass a DecoderReuseEvaluation to AnalyticsListener's onVideoInputFormatChanged and onAudioInputFormatChanged methods. The DecoderReuseEvaluation indicates whether it was possible to re-use an existing decoder instance for the new format, and if not then the reasons why.
  • Video:
    • Fall back to AVC/HEVC decoders for Dolby Vision streams with level 10 to 13 (#8530).
    • Fix VP9 format capability checks on API level 23 and earlier. The platform does not correctly report the VP9 level supported by the decoder in this case, so we estimate it based on the decoder's maximum supported bitrate.
  • Audio:
    • Fix handling of audio session IDs (#8190). SimpleExoPlayer now generates an audio session ID on construction, which can be immediately queried by calling SimpleExoPlayer.getAudioSessionId. The audio session ID will only change if application code calls SimpleExoPlayer.setAudioSessionId.
    • Replace onAudioSessionId with onAudioSessionIdChanged in AudioListener and AnalyticsListener. Note that onAudioSessionIdChanged is called in fewer cases than onAudioSessionId was called, due to the improved handling of audio session IDs as described above.
    • Retry playback after some types of AudioTrack error.
    • Create E-AC3 JOC passthrough AudioTrack instances using the maximum supported channel count (instead of assuming 6 channels) from API 29.
  • Text:
    • Add support for the SSA primaryColour style attribute (#8435).
    • Fix CEA-708 sequence number discontinuity handling (#1807).
    • Fix CEA-708 handling of unexpectedly small packets (#1807).
  • Data sources:
    • For HttpDataSource implementations, default to using the user agent of the underlying network stack.
    • Deprecate HttpDataSource.Factory.getDefaultRequestProperties. HttpDataSource.Factory.setDefaultRequestProperties instead.
    • Add DefaultHttpDataSource.Factory and deprecate DefaultHttpDataSourceFactory.
  • Metadata retriever:
    • Parse Google Photos HEIC and JPEG motion photo metadata.
  • IMA extension:
    • Add support for playback of ads in playlists (#3750).
    • Add ImaAdsLoader.Builder.setEnableContinuousPlayback for setting whether to request ads for continuous playback.
    • Upgrade IMA SDK dependency to 3.22.0. This fixes leaking of the ad view group (#7344, #8339).
    • Fix a bug that could cause the next content position played after a seek to snap back to the cue point of the preceding ad, rather than the requested content position.
    • Fix a regression that caused an ad group to be skipped after an initial seek to a non-zero position. Unsupported VPAID ads will still be skipped, but only after the preload timeout rather than instantly (#8428, #7832).
    • Fix a regression that caused a short ad followed by another ad to be skipped due to playback being stuck buffering waiting for the second ad to load (#8492).
  • FFmpeg extension:
    • Link the FFmpeg library statically, saving 350KB in binary size on average.
  • OkHttp extension:
    • Add OkHttpDataSource.Factory and deprecate OkHttpDataSourceFactory.
  • Cronet extension:
    • Add CronetDataSource.Factory and deprecate CronetDataSourceFactory.
    • Support setting the user agent on CronetDataSource.Factory and CronetEngineWrapper.
  • MediaSession extension:
    • Support setPlaybackSpeed(float) and disable it by default. Use MediaSessionConnector.setEnabledPlaybackActions(long) to enable (#8229).
  • Remove deprecated symbols:
    • AdaptiveMediaSourceEventListener. Use MediaSourceEventListener instead.
    • DashMediaSource.Factory.setMinLoadableRetryCount(int). Use DashMediaSource.Factory.setLoadErrorHandlingPolicy(LoadErrorHandlingPolicy) instead.
