This release includes the following changes since the 1.1.1 release:

  • Common Library:
    • Add a @Nullable Throwable parameter to the methods in the Log.Logger interface. The message parameter to these methods no longer contains any information about the Throwable passed to the Log.{d,i,w,e}() methods, so implementations will need to manually append this information if desired (possibly using Logger.appendThrowableString(String, Throwable)).
    • Fix Kotlin compatibility issue where nullable generic type parameters and nullable array element types are not detected as nullable. Examples are TrackSelectorResult and SimpleDecoder method parameters (#6792).
    • Change default UI and notification behavior in Util.shouldShowPlayButton to show a "play" button while playback is temporarily suppressed (e.g. due to transient audio focus loss). The legacy behavior can be maintained by using PlayerView.setShowPlayButtonIfPlaybackIsSuppressed(false) or MediaSession.Builder.setShowPlayButtonIfPlaybackIsSuppressed(false) (#11213).
    • Upgrade androidx.annotation:annotation-experimental to 1.3.1 to fix https://issuetracker.google.com/251172715.
    • Move ExoPlayer.setAudioAttributes to the Player interface.
  • ExoPlayer:
    • Fix seeking issues in AC4 streams caused by not identifying decode-only samples correctly (#11000).
    • Add suppression of playback on unsuitable audio output devices (e.g. the built-in speaker on Wear OS devices) when this feature is enabled via ExoPlayer.Builder.setSuppressPlaybackOnUnsuitableOutput. The playback suppression reason will be updated as Player.PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT if playback is attempted when no suitable audio outputs are available, or if all suitable outputs are disconnected during playback. The suppression reason will be removed when a suitable output is connected.
    • Add MediaSource.canUpdateMediaItem and MediaSource.updateMediaItem to accept MediaItem updates after creation via Player.replaceMediaItem(s).
    • Allow MediaItem updates for all MediaSource classes provided by the library via Player.replaceMediaItem(s) (#33, #9978).
    • Rename MimeTypes.TEXT_EXOPLAYER_CUES to MimeTypes.APPLICATION_MEDIA3_CUES.
    • Add PngExtractor that sends and reads a whole PNG file into the TrackOutput as one sample.
    • Enhance SequenceableLoader.continueLoading(long) method in the SequenceableLoader interface to SequenceableLoader.continueLoading(LoadingInfo loadingInfo). LoadingInfo contains additional parameters, including playbackSpeed and lastRebufferRealtimeMs in addition to the existing playbackPositionUs.
    • Enhance ChunkSource.getNextChunk(long, long, List, ChunkHolder) method in the ChunkSource interface to ChunkSource.getNextChunk(LoadingInfo, long, List, ChunkHolder).
    • Add additional fields to Common Media Client Data (CMCD) logging: buffer starvation (bs), deadline (dl), playback rate (pr) and startup (su) (#8699).
    • Add luma and chroma bitdepth to ColorInfo (#491).
    • Add additional fields to Common Media Client Data (CMCD) logging: next object request (nor) and next range request (nrr) (#8699).
    • Add functionality to transmit Common Media Client Data (CMCD) data using query parameters (#553).
    • Fix ConcurrentModificationException in ExperimentalBandwidthMeter (#612).
    • Add MediaPeriodId parameter to CompositeMediaSource.getMediaTimeForChildMediaTime.
    • Support ClippingMediaSource (and other sources with period/window time offsets) in ConcatenatingMediaSource2 (#11226).
    • Change BaseRenderer.onStreamChanged() to also receive a MediaPeriodId argument.
  • Transformer:
    • Parse EXIF rotation data for image inputs.
    • Remove TransformationRequest.HdrMode annotation type and its associated constants. Use Composition.HdrMode and its associated constants instead.
    • Simplify the OverlaySettings to fix rotation issues.
    • Changed frameRate and durationUs parameters of SampleConsumer.queueInputBitmap to TimestampIterator.
  • Track Selection:
    • Add DefaultTrackSelector.Parameters.allowAudioNonSeamlessAdaptiveness to explicitly allow or disallow non-seamless adaptation. The default stays at its current behavior of true.
  • Extractors:
    • MPEG-TS: Ensure the last frame is rendered by passing the last access unit of a stream to the sample queue (#7909).
    • Fix typo when determining rotationDegrees. Changed projectionPosePitch to projectionPoseRoll (#461).
    • Remove the assumption that Extractor instances can be directly inspected with instanceof. If you want runtime access to the implementation details of an Extractor you must first call Extractor.getUnderlyingInstance.
    • Add BmpExtractor.
    • Add WebpExtractor.
    • Add HeifExtractor.
    • Add QuickTime classic support to Mp4Extractor.
  • Audio:
    • Add support for 24/32-bit big-endian PCM in MP4 and Matroska, and parse PCM encoding for lpcm in MP4.
    • Add support for extracting Vorbis audio in MP4.
    • Add AudioSink.getFormatOffloadSupport(Format) that retrieves level of offload support the sink can provide for the format through a DefaultAudioOffloadSupportProvider. It returns the new AudioOffloadSupport that contains isFormatSupported, isGaplessSupported, and isSpeedChangeSupported.
    • Add AudioSink.setOffloadMode() through which the offload configuration on the audio sink is configured. Default is AudioSink.OFFLOAD_MODE_DISABLED.
    • Offload can be enabled through setAudioOffloadPreference in TrackSelectionParameters. If the set preference is to enable, the device supports offload for the format, and the track selection is a single audio track, then audio offload will be enabled.
    • If audioOffloadModePreference is set to AUDIO_OFFLOAD_MODE_PREFERENCE_REQUIRED, then the DefaultTrackSelector will only select an audio track and only if that track's format is supported in offload. If no audio track is supported in offload, then no track will be selected.
    • Disabling gapless support for offload when pre-API level 33 due to playback position issue after track transition.
    • Remove parameter enableOffload from DefaultRenderersFactory.buildAudioSink method signature.
    • Remove method DefaultAudioSink.Builder.setOffloadMode.
    • Remove intdef value DefaultAudioSink.OffloadMode.OFFLOAD_MODE_ENABLED_GAPLESS_DISABLED.
    • Add support for Opus gapless metadata during offload playback.
    • Allow renderer recovery by disabling offload if failed at first write (#627).
    • Enable Offload Scheduling by default for audio-only offloaded playback.
    • Delete ExoPlayer.experimentalSetOffloadSchedulingEnabled and AudioOffloadListener.onExperimentalOffloadSchedulingEnabledChanged.
    • Renamed onExperimentalSleepingForOffloadChanged as onSleepingForOffloadChanged and onExperimentalOffloadedPlayback as onOffloadedPlayback.
    • Move audio offload mode related TrackSelectionParameters interfaces and definitions to an inner AudioOffloadPreferences class.
    • Add onAudioTrackInitialized and onAudioTrackReleased callbacks to AnalyticsListener, AudioRendererEventListener and AudioSink.Listener.
    • Fix DTS Express audio buffer underflow issue (#650).
    • Fix bug where the capabilities check for E-AC3-JOC throws an IllegalArgumentException (#677).
  • Video:
    • Allow MediaCodecVideoRenderer to use a custom VideoFrameProcessor.Factory.
    • Fix bug where the first frame couldn't be rendered if the audio stream starts with negative timestamps (#291).
  • Text:
    • Remove ExoplayerCuesDecoder. Text tracks with sampleMimeType = application/x-media3-cues are now directly handled by TextRenderer without needing a SubtitleDecoder instance.
  • Metadata:
    • MetadataDecoder.decode will no longer be called for "decode-only" samples as the implementation must return null anyway.
  • Effect:
    • Add VideoFrameProcessor.queueInputBitmap(Bitmap, Iterator<Long>) queuing bitmap input by timestamp.
    • Change VideoFrameProcessor.registerInputStream() to be non-blocking. Apps must implement VideoFrameProcessor.Listener#onInputStreamRegistered().
    • Changed frameRate and durationUs parameters of VideoFrameProcessor.queueInputBitmap to TimestampIterator.
  • IMA extension:
    • Fix bug where a multi-period DASH live stream that is not the first item in a playlist can throw an exception (#571).
    • Release StreamManager before calling AdsLoader.destroy()
    • Bump IMA SDK version to 3.31.0.
  • Session:
    • Set the notifications foreground service behavior to FOREGROUND_SERVICE_IMMEDIATE in DefaultMediaNotificationProvider (#167).
    • Use only android.media.session.MediaSession.setMediaButtonBroadcastReceiver() above API 31 to avoid problems with deprecated API on Samsung devices (#167).
    • Use the media notification controller as proxy to set available commands and custom layout used to populate the notification and the platform session.
    • Convert media button events that are received by MediaSessionService.onStartCommand() within Media3 instead of routing them to the platform session and back to Media3. With this, the caller controller is always the media notification controller and apps can easily recognize calls coming from the notification in the same way on all supported API levels.
    • Fix bug where MediaController.getCurrentPosition() is not advancing when connected to a legacy MediaSessionCompat.
    • Add MediaLibrarySession.getSubscribedControllers(mediaId) for convenience.
    • Override MediaLibrarySession.Callback.onSubscribe() to assert the availability of the parent ID for which the controller subscribes. If successful, the subscription is accepted and notifyChildrenChanged() is called immediately to inform the browser (#561).
    • Add session demo module for Automotive OS and enable session demo for Android Auto.
    • Do not set the queue of the framework session when COMMAND_GET_TIMELINE is not available for the media notification controller. With Android Auto as the client controller reading from the framework session, this has the effect that the queue button in the UI of Android Auto is not displayed (#339).
    • Use DataSourceBitmapLoader by default instead of SimpleBitmapLoader (#271, #327).
    • Add MediaSession.Callback.onMediaButtonEvent(Intent) that allows apps to override the default media button event handling.
  • UI:
    • Add a Player.Listener implementation for Wear OS devices that handles playback suppression due to Player.PLAYBACK_SUPPRESSION_REASON_UNSUITABLE_AUDIO_OUTPUT by launching a system dialog to allow a user to connect a suitable audio output (e.g. bluetooth headphones). The listener will auto-resume playback if a suitable device is connected within a configurable timeout (default is 5 minutes).
  • Downloads:
    • Declare "data sync" foreground service type for DownloadService for Android 14 compatibility. When using this service, the app also needs to add dataSync as foregroundServiceType in the manifest and add the FOREGROUND_SERVICE_DATA_SYNC permission (#11239).
  • HLS Extension:
    • Refresh the HLS live playlist with an interval calculated from the last load start time rather than the last load completed time (#663).
  • DASH Extension:
    • Allow multiple of the same DASH identifier in segment template url.
    • Add experimental support for parsing subtitles during extraction. This has better support for merging overlapping subtitles, including resolving flickering when transitioning between subtitle segments. You can enable this using DashMediaSource.Factory.experimentalParseSubtitlesDuringExtraction() (#288).
  • RTSP Extension:
    • Fix a race condition that could lead to IndexOutOfBoundsException when falling back to TCP, or playback hanging in some situations.
    • Check state in RTSP setup when returning loading state of RtspMediaPeriod (#577).
    • Ignore custom Rtsp request methods in Options response public header (#613).
    • Use RTSP Setup Response timeout value in time interval of sending keep-alive RTSP Options requests (#662).
  • Decoder Extensions (FFmpeg, VP9, AV1, MIDI, etc.):
    • Release the MIDI decoder module, which provides support for playback of standard MIDI files using the Jsyn library to synthesize audio.
    • Add DecoderOutputBuffer.shouldBeSkipped to directly mark output buffers that don't need to be presented. This is preferred over C.BUFFER_FLAG_DECODE_ONLY that will be deprecated.
    • Add Decoder.setOutputStartTimeUs and SimpleDecoder.isAtLeastOutputStartTimeUs to allow decoders to drop decode-only samples before the start time. This should be preferred to Buffer.isDecodeOnly that will be deprecated.
    • Fix bug publishing MIDI decoder artifact to Maven repository. The artifact is renamed to media3-exoplayer-midi (#734).
  • Leanback extension:
    • Fix bug where disabling a surface can cause an ArithmeticException in Leanback code (#617).
  • Test Utilities:
    • Make TestExoPlayerBuilder and FakeClock compatible with Espresso UI tests and Compose UI tests. This fixes a bug where playback advances non-deterministically during Espresso or Compose view interactions.
  • Remove deprecated symbols:
    • Remove TransformationRequest.Builder.setEnableRequestSdrToneMapping(boolean) and TransformationRequest.Builder.experimental_setEnableHdrEditing(boolean). Use Composition.Builder.setHdrMode(int) and pass the Composition to Transformer.start(Composition, String) instead.
    • Remove deprecated DownloadNotificationHelper.buildProgressNotification method, use a non deprecated method that takes a notMetRequirements parameter instead.
