Version 1.2.0

Version 1.2.0-alpha02

  • Common Library:
    • Upgrade androidx.annotation:annotation-experimental to 1.3.1. This also introduces a transitive dependency on the Kotlin standard library from media3-common. Apps can downgrade to remove this dependency if they want. Fixes
    • Move ExoPlayer.setAudioAttributes to the Player interface.
  • ExoPlayer:
    • 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:
    • Changed frameRate and durationUs parameters of SampleConsumer.queueInputBitmap to TimestampIterator.
  • Extractors:
    • Add BmpExtractor.
    • Add WebpExtractor.
    • Add HeifExtractor.
    • Add QuickTime classic support to Mp4Extractor.
  • Audio:
    • 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.
  • Effect:
    • 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 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 parentId for which the controller subscribes. If successful, the subscription is accepted and notifyChildrenChanged() is called immediately to inform the browser (#561).
  • 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).
  • Leanback extension:
    • Fix bug where disabling a surface can cause an ArithmeticException in Leanback code (#617).

Version 1.2.0-alpha01

  • 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).
  • 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)).
    • 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).
  • 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.
  • 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.
  • 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.
  • Audio Offload:
    • 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.
  • 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).
  • Effect:
    • Add VideoFrameProcessor.queueInputBitmap(Bitmap, Iterator<Long>) queuing bitmap input by timestamp.
  • 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).
  • MIDI extension:
    • Release the MIDI decoder module, which provides support for playback of standard MIDI files using the Jsyn library to synthesize audio.
  • 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.

Version 1.1.0

Version 1.1.1

  • Common Library:
    • Remove accidentally added multidex dependency from all modules (#499).
  • ExoPlayer:
    • Fix issue in PlaybackStatsListener where spurious PlaybackStats are created after the playlist is cleared.
    • Add additional fields to Common Media Client Data (CMCD) logging: streaming format (sf), stream type (st), version (v), top birate (tb), object duration (d), measured throughput (mtp) and object type (ot) (#8699).
  • Audio:
    • Fix a bug where Player.getState() never transitioned to STATE_ENDED when playing very short files (#538).
  • Audio Offload:
    • Prepend Ogg ID Header and Comment Header Pages to bitstream for offloaded Opus playback in accordance with RFC 7845.
  • Video:
    • H.265/HEVC: Fix parsing SPS short and long term reference picture info.
  • Text:
    • CEA-608: Change cue truncation logic to only consider visible text. Previously indent and tab offset were included when limiting the cue length to 32 characters (which was technically correct by the spec) (#11019).
  • IMA extension:
    • Bump IMA SDK version to 3.30.3.
  • Session:
    • Add custom layout to the state of the controller and provide a getter to access it. When the custom layout changes, MediaController.Listener.onCustomLayoutChanged is called. Apps that want to send different custom layouts to different Media3 controller can do this in MediaSession.Callback.onConnect by using an AcceptedResultBuilder to make sure the custom layout is available to the controller when connection completes.
    • Fix cases where MediaLibraryServiceLegacyStub sent an error to a Result that didn't support this which produced an UnsupportedOperationException (#78).
    • Fix the way PlayerWrapper creates a VolumeProviderCompat by determining volumeControlType through both legacy commands (COMMAND_ADJUST_DEVICE_VOLUME and COMMAND_SET_DEVICE_VOLUME) and new commands (COMMAND_ADJUST_DEVICE_VOLUME_WITH_FLAGS and COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS) (#554).

Version 1.1.0

  • Common Library:
    • Add suppression reason for unsuitable audio route and play when ready change reason for suppressed too long. (#15).
    • Add commands to Player:
    • Add overloaded methods to Player which allow users to specify volume flags:
      • void setDeviceVolume(int, int)
      • void increaseDeviceVolume(int)
      • void decreaseDeviceVolume(int)
      • void setDeviceMuted(boolean, int)
    • Add Builder for DeviceInfo and deprecate existing constructor.
    • Add DeviceInfo.routingControllerId to specify the routing controller ID for remote playbacks.
    • Add Player.replaceMediaItem(s) as a shortcut to adding and removing items at the same position (#8046).
  • ExoPlayer:
    • Allow ExoPlayer to have control of device volume methods only if explicitly opted in. Use ExoPlayer.Builder.setDeviceVolumeControlEnabled to have access to:
      • getDeviceVolume()
      • isDeviceMuted()
      • setDeviceVolume(int) and setDeviceVolume(int, int)
      • increaseDeviceVolume(int) and increaseDeviceVolume(int, int)
      • decreaseDeviceVolume(int) and decreaseDeviceVolume(int, int)
    • Add FilteringMediaSource that allows to filter available track types from a MediaSource.
    • Add support for including Common Media Client Data (CMCD) in the outgoing requests of adaptive streaming formats DASH, HLS, and SmoothStreaming. The following fields, br, bl, cid, rtp, and sid, have been incorporated (#8699). API structure and API methods:
      • CMCD logging is disabled by default, use MediaSource.Factory.setCmcdConfigurationFactory(CmcdConfiguration.Factory cmcdConfigurationFactory) to enable it.
      • All keys are enabled by default, override CmcdConfiguration.RequestConfig.isKeyAllowed(String key) to filter out which keys are logged.
      • Override CmcdConfiguration.RequestConfig.getCustomData() to enable custom key logging.
    • Add additional action to manifest of main demo to make it easier to start the demo app with a custom *.exolist.json file (#439).
    • Add ExoPlayer.setVideoEffects() for using Effect during video playback.
    • Update SampleQueue to store sourceId as a long rather than an int. This changes the signatures of public methods SampleQueue.sourceId and SampleQueue.peekSourceId.
    • Add parameters to LoadControl methods shouldStartPlayback and onTracksSelected that allow associating these methods with the relevant MediaPeriod.
    • Change signature of ServerSideAdInsertionMediaSource.setAdPlaybackStates(Map<Object, AdPlaybackState>) by adding a timeline parameter that contains the periods with the UIDs used as keys in the map. This is required to avoid concurrency issues with multi-period live streams.
    • Deprecate EventDispatcher.withParameters(int windowIndex, @Nullable MediaPeriodId mediaPeriodId, long mediaTimeOffsetMs) and BaseMediaSource.createEventDispatcher(..., long mediaTimeOffsetMs). The variant of the methods without the mediaTimeOffsetUs can be called instead. Note that even for the deprecated variants, the offset is not anymore added to startTimeUs and endTimeUs of the MediaLoadData objects that are dispatched by the dispatcher.
    • Rename ExoTrackSelection.blacklist to excludeTrack and isBlacklisted to isTrackExcluded.
    • Fix inconsistent behavior between ExoPlayer.setMediaItem(s) and addMediaItem(s) when called on an empty playlist.
  • Transformer:
    • Remove Transformer.Builder.setMediaSourceFactory(MediaSource.Factory). Use ExoPlayerAssetLoader.Factory(MediaSource.Factory) and Transformer.Builder.setAssetLoaderFactory(AssetLoader.Factory) instead.
    • Remove Transformer.startTransformation(MediaItem, ParcelFileDescriptor).
    • Fix a bug where transformation could get stuck (leading to muxer timeout) if the end of the video stream was signaled at the moment when an input frame was pending processing.
    • Query codecs via MediaCodecList instead of using findDecoder/EncoderForFormat utilities, to expand support.
    • Remove B-frame configuration in DefaultEncoderFactory because it doesn't work on some devices.
  • Track selection:
    • Add DefaultTrackSelector.Parameters.allowInvalidateSelectionsForRendererCapabilitiesChange which is disabled by default. When enabled, the DefaultTrackSelector will trigger a new track selection when the renderer capabilities changed.
  • Extractors:
    • Ogg: Fix bug when seeking in files with a long duration (#391).
    • FMP4: Fix issue where TimestampAdjuster initializes a wrong timestamp offset with metadata sample time from emsg atom (#356).
  • Audio:
    • Fix bug where some playbacks fail when tunneling is enabled and AudioProcessors are active, e.g. for gapless trimming (#10847).
    • Encapsulate Opus frames in Ogg packets in direct playbacks (offload).
    • Extrapolate current position during sleep with offload scheduling.
    • Add Renderer.release() and AudioSink.release() for releasing the resources at the end of player's lifecycle.
    • Listen to audio capabilities changes in DefaultAudioSink. Add a required parameter context in the constructor of DefaultAudioSink, with which the DefaultAudioSink will register as the listener to the AudioCapabilitiesReceiver and update its audioCapabilities property when informed with a capabilities change.
    • Propagate audio capabilities changes via a new event onAudioCapabilitiesChanged in AudioSink.Listener interface, and a new interface RendererCapabilities.Listener which triggers onRendererCapabilitiesChanged events.
    • Add ChannelMixingAudioProcessor for applying scaling/mixing to audio channels.
    • Add new int value DISCARD_REASON_AUDIO_BYPASS_POSSIBLE to DecoderDiscardReasons to discard audio decoder when bypass mode is possible after audio capabilities change.
    • Add direct playback support for DTS Express and DTS:X (#335).
  • Video:
    • Make MediaCodecVideoRenderer report a VideoSize with a width and height of 0 when the renderer is disabled. Player.Listener.onVideoSizeChanged is called accordingly when Player.getVideoSize() changes. With this change, ExoPlayer's video size with MediaCodecVideoRenderer has a width and height of 0 when Player.getCurrentTracks does not support video, or the size of the supported video track is not yet determined.
  • DRM:
    • Reduce the visibility of several internal-only methods on DefaultDrmSession that aren't expected to be called from outside the DRM package:
      • void onMediaDrmEvent(int)
      • void provision()
      • void onProvisionCompleted()
      • onProvisionError(Exception, boolean)
  • Muxer:
    • Add a new muxer library which can be used to create an MP4 container file.
  • IMA extension:
    • Enable multi-period live DASH streams for DAI. Please note that the current implementation does not yet support seeking in live streams (#10912).
    • Fix a bug where a new ad group is inserted in live streams because the calculated content position in consecutive timelines varies slightly.
  • Session:
    • Add helper method MediaSession.getControllerForCurrentRequest to obtain information about the controller that is currently calling aPlayer method.
    • Add androidx.media3.session.MediaButtonReceiver to enable apps to implement playback resumption with media button events sent by, for example, a Bluetooth headset (#167).
    • Add default implementation to MediaSession.Callback.onAddMediaItems to allow requested MediaItems to be passed onto Player if they have LocalConfiguration (e.g. URI) (#282).
    • Add "seek to previous" and "seek to next" command buttons on compact media notification view by default for Android 12 and below (#410).
    • Add default implementation to MediaSession.Callback.onAddMediaItems to allow requested MediaItems to be passed onto Player if they have LocalConfiguration (e.g. URI) (#282).
    • Add "seek to previous" and "seek to next" command buttons on compact media notification view by default for Android 12 and below (#410).
  • UI:
    • Add Util methods shouldShowPlayButton and handlePlayPauseButtonAction to write custom UI elements with a play/pause button.
  • RTSP Extension:
    • For MPEG4-LATM, use default profile-level-id value if absent in Describe Response SDP message (#302).
    • Use base Uri for relative path resolution from the RTSP session if present in DESCRIBE response header (#11160).
  • DASH Extension:
    • Remove the media time offset from MediaLoadData.startTimeMs and MediaLoadData.endTimeMs for multi period DASH streams.
    • Fix a bug where re-preparing a multi-period live Dash media source produced a IndexOutOfBoundsException (#10838).
  • HLS Extension:
    • Add HlsMediaSource.Factory.setTimestampAdjusterInitializationTimeoutMs(long) to set a timeout for the loading thread to wait for the TimestampAdjuster to initialize. If the initialization doesn't complete before the timeout, a PlaybackException is thrown to avoid the playback endless stalling. The timeout is set to zero by default (#323).
  • Test Utilities:
    • Check for URI scheme case insensitivity in DataSourceContractTest.
  • Remove deprecated symbols:
    • Remove DefaultAudioSink constructors, use DefaultAudioSink.Builder instead.
    • Remove HlsMasterPlaylist, use HlsMultivariantPlaylist instead.
    • Remove Player.stop(boolean). Use Player.stop() and Player.clearMediaItems() (if reset is true) instead.
    • Remove two deprecated SimpleCache constructors, use a non-deprecated constructor that takes a DatabaseProvider instead for better performance.
    • Remove DefaultBandwidthMeter constructor, use DefaultBandwidthMeter.Builder instead.
    • Remove DefaultDrmSessionManager constructors, use DefaultDrmSessionManager.Builder instead.
    • Remove two deprecated HttpDataSource.InvalidResponseCodeException constructors, use a non-deprecated constructor that accepts additional fields(cause, responseBody) to enhance error logging.
    • Remove DownloadHelper.forProgressive, DownloadHelper.forHls, DownloadHelper.forDash, and DownloadHelper.forSmoothStreaming, use DownloadHelper.forMediaItem instead.
    • Remove deprecated DownloadService constructor, use a non deprecated constructor that includes the option to provide a channelDescriptionResourceId parameter.
    • Remove deprecated String constants for Charsets (ASCII_NAME, UTF8_NAME, ISO88591_NAME, UTF16_NAME and UTF16LE_NAME), use Kotlin Charsets from the kotlin.text package, the java.nio.charset.StandardCharsets or the instead.
    • Remove deprecated WorkManagerScheduler constructor, use a non deprecated constructor that includes the option to provide a Context parameter instead.
    • Remove the deprecated methods createVideoSampleFormat, createAudioSampleFormat, createContainerFormat, and createSampleFormat, which were used to instantiate the Format class. Instead use Format.Builder for creating instances of Format.
    • Remove the deprecated methods copyWithMaxInputSize, copyWithSubsampleOffsetUs, copyWithLabel, copyWithManifestFormatInfo, copyWithGaplessInfo, copyWithFrameRate, copyWithDrmInitData, copyWithMetadata, copyWithBitrate and copyWithVideoSize, use Format.buildUpon() and setter methods instead.
    • Remove deprecated ExoPlayer.retry(), use prepare() instead.
    • Remove deprecated zero-arg DefaultTrackSelector constructor, use DefaultTrackSelector(Context) instead.
    • Remove deprecated OfflineLicenseHelper constructor, use OfflineLicenseHelper(DefaultDrmSessionManager, DrmSessionEventListener.EventDispatcher) instead.
    • Remove deprecated DownloadManager constructor, use the constructor that takes an Executor instead.
    • Remove deprecated Cue constructors, use Cue.Builder instead.
    • Remove deprecated OfflineLicenseHelper constructor, use OfflineLicenseHelper(DefaultDrmSessionManager, DrmSessionEventListener.EventDispatcher) instead.
    • Remove four deprecated AnalyticsListener methods:
      • onDecoderEnabled, use onAudioEnabled and/or onVideoEnabled instead.
      • onDecoderInitialized, use onAudioDecoderInitialized and/or onVideoDecoderInitialized instead.

Version 1.0.0-beta01

June 16, 2022

androidx.media3:media3-*:1.0.0-beta01 is released. Version 1.0.0-beta01 contains these commits.

This corresponds to the ExoPlayer 2.18.0 release.

  • Core library:
    • Enable support for Android platform diagnostics via MediaMetricsManager. ExoPlayer will forward playback events and performance data to the platform, which helps to provide system performance and debugging information on the device. This data may also be collected by Google if sharing usage and diagnostics data is enabled by the user of the device. Apps can opt-out of contributing to platform diagnostics for ExoPlayer with ExoPlayer.Builder.setUsePlatformDiagnostics(false).
    • Fix bug that tracks are reset too often when using MergingMediaSource, for example when side-loading subtitles and changing the selected subtitle mid-playback (#10248).
    • Stop detecting 5G-NSA network type on API 29 and 30. These playbacks will assume a 4G network.
    • Disallow passing null to MediaSource.Factory.setDrmSessionManagerProvider and MediaSource.Factory.setLoadErrorHandlingPolicy. Instances of DefaultDrmSessionManagerProvider and DefaultLoadErrorHandlingPolicy can be passed explicitly if required.
    • Add MediaItem.RequestMetadata to represent metadata needed to play media when the exact LocalConfiguration is not known. Also remove MediaMetadata.mediaUrl as this is now included in RequestMetadata.
    • Add Player.Command.COMMAND_SET_MEDIA_ITEM to enable players to allow setting a single item.
  • Track selection:
    • Flatten TrackSelectionOverrides class into TrackSelectionParameters, and promote TrackSelectionOverride to a top level class.
    • Rename TracksInfo to Tracks and TracksInfo.TrackGroupInfo to Tracks.Group. Player.getCurrentTracksInfo and Player.Listener.onTracksInfoChanged have also been renamed to Player.getCurrentTracks and Player.Listener.onTracksChanged. This includes 'un-deprecating' the Player.Listener.onTracksChanged method name, but with different parameter types.
    • Change DefaultTrackSelector.buildUponParameters and DefaultTrackSelector.Parameters.buildUpon to return DefaultTrackSelector.Parameters.Builder instead of the deprecated DefaultTrackSelector.ParametersBuilder.
    • Add DefaultTrackSelector.Parameters.constrainAudioChannelCountToDeviceCapabilities which is enabled by default. When enabled, the DefaultTrackSelector will prefer audio tracks whose channel count does not exceed the device output capabilities. On handheld devices, the DefaultTrackSelector will prefer stereo/mono over multichannel audio formats, unless the multichannel format can be Spatialized (Android 12L+) or is a Dolby surround sound format. In addition, on devices that support audio spatialization, the DefaultTrackSelector will monitor for changes in the Spatializer properties and trigger a new track selection upon these. Devices with a television UI mode are excluded from these constraints and the format with the highest channel count will be preferred. To enable this feature, the DefaultTrackSelector instance must be constructed with a Context.
  • Video:
    • Rename DummySurface to PlaceholderSurface.
    • Add AV1 support to the MediaCodecVideoRenderer.getCodecMaxInputSize.
  • Audio:
    • Use LG AC3 audio decoder advertising non-standard MIME type.
    • Change the return type of AudioAttributes.getAudioAttributesV21() from to a new AudioAttributesV21 wrapper class, to prevent slow ART verification on API < 21.
    • Query the platform (API 29+) or assume the audio encoding channel count for audio passthrough when the format audio channel count is unset, which occurs with HLS chunkless preparation (10204).
    • Configure AudioTrack with channel mask AudioFormat.CHANNEL_OUT_7POINT1POINT4 if the decoder outputs 12 channel PCM audio (#10322.
  • DRM
    • Ensure the DRM session is always correctly updated when seeking immediately after a format change (10274).
  • Text:
    • Change Player.getCurrentCues() to return CueGroup instead of List<Cue>.
    • SSA: Support OutlineColour style setting when BorderStyle == 3 (i.e. OutlineColour sets the background of the cue) (#8435).
    • CEA-708: Parse data into multiple service blocks and ignore blocks not associated with the currently selected service number.
    • Remove RawCcExtractor, which was only used to handle a Google-internal subtitle format.
  • Extractors:
    • Add support for AVI (#2092).
    • Matroska: Parse DiscardPadding for Opus tracks.
    • MP4: Parse bitrates from esds boxes.
    • Ogg: Allow duplicate Opus ID and comment headers (#10038).
  • UI:
    • Fix delivery of events to OnClickListeners set on PlayerView in the case that useController=false (#9605). Also fix delivery of events to OnLongClickListener for all view configurations.
    • Fix incorrectly treating a sequence of touch events that exit the bounds of PlayerView before ACTION_UP as a click (#9861).
    • Fix PlayerView accessibility issue where tapping might toggle playback rather than hiding the controls (#8627).
    • Rewrite TrackSelectionView and TrackSelectionDialogBuilder to work with the Player interface rather than ExoPlayer. This allows the views to be used with other Player implementations, and removes the dependency from the UI module to the ExoPlayer module. This is a breaking change.
    • Don't show forced text tracks in the PlayerView track selector, and keep a suitable forced text track selected if "None" is selected (#9432).
  • DASH:
    • Parse channel count from DTS AudioChannelConfiguration elements. This re-enables audio passthrough for DTS streams (#10159).
    • Disallow passing null to DashMediaSource.Factory.setCompositeSequenceableLoaderFactory. Instances of DefaultCompositeSequenceableLoaderFactory can be passed explicitly if required.
  • HLS:
    • Fallback to chunkful preparation if the playlist CODECS attribute does not contain the audio codec (#10065).
    • Disallow passing null to HlsMediaSource.Factory.setCompositeSequenceableLoaderFactory, HlsMediaSource.Factory.setPlaylistParserFactory, and HlsMediaSource.Factory.setPlaylistTrackerFactory. Instances of DefaultCompositeSequenceableLoaderFactory, DefaultHlsPlaylistParserFactory, or a reference to DefaultHlsPlaylistTracker.FACTORY can be passed explicitly if required.
  • Smooth Streaming:
    • Disallow passing null to SsMediaSource.Factory.setCompositeSequenceableLoaderFactory. Instances of DefaultCompositeSequenceableLoaderFactory can be passed explicitly if required.
  • RTSP:
    • Add RTP reader for H263 (#63).
    • Add RTP reader for MPEG4 (#35).
    • Add RTP reader for HEVC (#36).
    • Add RTP reader for AMR. Currently only mono-channel, non-interleaved AMR streams are supported. Compound AMR RTP payload is not supported. (#46)
    • Add RTP reader for VP8 (#47).
    • Add RTP reader for WAV (#56).
    • Fix RTSP basic authorization header. (#9544).
    • Stop checking mandatory SDP fields as ExoPlayer doesn't need them (#10049).
    • Throw checked exception when parsing RTSP timing (#10165).
    • Add RTP reader for VP9 (#47).
    • Add RTP reader for OPUS (#53).
  • Data sources:
    • Rename DummyDataSource to PlaceholderDataSource.
    • Workaround OkHttp interrupt handling.
  • Session:
    • Replace MediaSession.MediaItemFiller with MediaSession.Callback.onAddMediaItems to allow asynchronous resolution of requests.
    • Support setMediaItems(s) methods when MediaController connects to a legacy media session.
    • Remove MediaController.setMediaUri and MediaSession.Callback.onSetMediaUri. The same functionality can be achieved by using MediaController.setMediaItem and MediaSession.Callback.onAddMediaItems.
    • Forward legacy MediaController calls to play media to MediaSession.Callback.onAddMediaItems instead of onSetMediaUri.
    • Add MediaNotification.Provider and DefaultMediaNotificationProvider to provide customization of the notification.
    • Add BitmapLoader and SimpleBitmapLoader for downloading artwork images.
    • Add MediaSession.setCustomLayout() to provide backwards compatibility with the legacy session.
    • Add MediaSession.setSessionExtras() to provide feature parity with legacy session.
    • Rename MediaSession.MediaSessionCallback to MediaSession.Callback, MediaLibrarySession.MediaLibrarySessionCallback to MediaLibrarySession.Callback and MediaSession.Builder.setSessionCallback to setCallback.
    • Fix NPE in MediaControllerImplLegacy (#59).
    • Update session position info on timeline change(#51).
    • Fix NPE in MediaControllerImplBase after releasing controller (#74).
  • Ad playback / IMA:
    • Decrease ad polling rate from every 100ms to every 200ms, to line up with Media Rating Council (MRC) recommendations.
  • FFmpeg extension:
    • Update CMake version to 3.21.0+ to avoid a CMake bug causing AndroidStudio's gradle sync to fail (#9933).
  • Remove deprecated symbols:
    • Remove Player.Listener.onTracksChanged(TrackGroupArray, TrackSelectionArray). Use Player.Listener.onTracksChanged(Tracks) instead.
    • Remove Player.getCurrentTrackGroups and Player.getCurrentTrackSelections. Use Player.getCurrentTracks instead. You can also continue to use ExoPlayer.getCurrentTrackGroups and ExoPlayer.getCurrentTrackSelections, although these methods remain deprecated.
    • Remove DownloadHelper DEFAULT_TRACK_SELECTOR_PARAMETERS_WITHOUT_VIEWPORT and DEFAULT_TRACK_SELECTOR_PARAMETERS constants. Use getDefaultTrackSelectorParameters(Context) instead when possible, and DEFAULT_TRACK_SELECTOR_PARAMETERS_WITHOUT_CONTEXT otherwise.
    • Remove constructor DefaultTrackSelector(ExoTrackSelection.Factory). Use DefaultTrackSelector(Context, ExoTrackSelection.Factory) instead.
    • Remove Transformer.Builder.setContext. The Context should be passed to the Transformer.Builder constructor instead.

Version 1.0.0-alpha03

    • Fix audio underruns between ad periods in live HLS SSAI streams.

Version 1.0.0-alpha02

March 2, 2022

androidx.media3:media3-*:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

This corresponds to the ExoPlayer 2.17.0 release.

  • Core Library:
    • Add protected method DefaultRenderersFactory.getCodecAdapterFactory() so that subclasses of DefaultRenderersFactory that override buildVideoRenderers() or buildAudioRenderers() can access the codec adapter factory and pass it to MediaCodecRenderer instances they create.
    • Propagate ICY header fields name and genre to MediaMetadata.station and MediaMetadata.genre respectively so that they reach the app via Player.Listener.onMediaMetadataChanged() (#9677).
    • Remove null keys from DefaultHttpDataSource#getResponseHeaders.
    • Sleep and retry when creating a MediaCodec instance fails. This works around an issue that occurs on some devices when switching a surface from a secure codec to another codec (#8696).
    • Add MediaCodecAdapter.getMetrics() to allow users obtain metrics data from MediaCodec. (#9766).
    • Fix Maven dependency resolution (#8353).
    • Disable automatic speed adjustment for live streams that neither have low-latency features nor a user request setting the speed (#9329).
    • Rename DecoderCounters#inputBufferCount to queuedInputBufferCount.
    • Make SimpleExoPlayer.renderers private. Renderers can be accessed via ExoPlayer.getRenderer.
    • Updated some AnalyticsListener.EventFlags constant values to match values in Player.EventFlags.
    • Split AnalyticsCollector into an interface and default implementation to allow it to be stripped by R8 if an app doesn't need it.
  • Track selection:
    • Support preferred video role flags in track selection (#9402).
    • Update video track selection logic to take preferred MIME types and role flags into account when selecting multiple video tracks for adaptation (#9519).
    • Update video and audio track selection logic to only choose formats for adaptive selections that have the same level of decoder and hardware support (#9565).
    • Update video track selection logic to prefer more efficient codecs if multiple codecs are supported by primary, hardware-accelerated decoders (#4835).
    • Prefer audio content preferences (for example, the "default" audio track or a track matching the system locale language) over technical track selection constraints (for example, preferred MIME type, or maximum channel count).
    • Fix track selection issue where overriding one track group did not disable other track groups of the same type (#9675).
    • Fix track selection issue where a mixture of non-empty and empty track overrides is not applied correctly (#9649).
    • Prohibit duplicate TrackGroups in a TrackGroupArray. TrackGroups can always be made distinguishable by setting an id in the TrackGroup constructor. This fixes a crash when resuming playback after backgrounding the app with an active track override (#9718).
    • Amend logic in AdaptiveTrackSelection to allow a quality increase under sufficient network bandwidth even if playback is very close to the live edge (#9784).
  • Video:
    • Fix decoder fallback logic for Dolby Vision to use a compatible H264/H265 decoder if needed.
  • Audio:

  • Extractors:
    • WAV: Add support for RF64 streams (#9543).
    • Fix incorrect parsing of H.265 SPS NAL units (#9719).
    • Parse Vorbis Comments (including METADATA_BLOCK_PICTURE) in Ogg Opus and Ogg Vorbis files.
  • Text:
    • Add a field which is propagated to the field of the subtitle track created from the configuration (#9673).
    • Add basic support for WebVTT subtitles in Matroska containers (#9886).
    • Prevent Cea708Decoder from reading more than the declared size of a service block.
  • DRM:
    • Remove playbackLooper from DrmSessionManager.(pre)acquireSession. When a DrmSessionManager is used by an app in a custom MediaSource, the playbackLooper needs to be passed to DrmSessionManager.setPlayer instead.
  • Ad playback / IMA:
    • Add support for IMA Dynamic Ad Insertion (DAI) (#8213).
    • Add a method to AdPlaybackState to allow resetting an ad group so that it can be played again (#9615).
    • Enforce playback speed of 1.0 during ad playback (#9018).
    • Fix issue where an ad group that failed to load caused an immediate playback reset (#9929).
  • UI:
    • Fix the color of the numbers in StyledPlayerView rewind and fastforward buttons when using certain themes (#9765).
    • Correctly translate playback speed strings (#9811).
  • DASH:
    • Add parsed essential and supplemental properties to the Representation (#9579).
    • Support the forced-subtitle track role (#9727).
    • Stop interpreting the main track role as C.SELECTION_FLAG_DEFAULT.
    • Fix base URL exclusion logic for manifests that do not declare the DVB namespace (#9856).
    • Support relative MPD.Location URLs (#9939).
  • HLS:
    • Correctly populate Format.label for audio only HLS streams (#9608).
    • Use chunkless preparation by default to improve start up time. If your renditions contain muxed closed-caption tracks that are not declared in the master playlist, you should add them to the master playlist to be available for playback, or turn off chunkless preparation with HlsMediaSource.Factory.setAllowChunklessPreparation(false).
    • Support key-frame accurate seeking in HLS (#2882).
  • RTSP:
    • Provide a client API to override the SocketFactory used for any server connection (#9606).
    • Prefer DIGEST authentication method over BASIC if both are present (#9800).
    • Handle when RTSP track timing is not available (#9775).
    • Ignore invalid RTP-Info header values (#9619).
  • Transformer:
    • Increase required min API version to 21.
    • TransformationException is now used to describe errors that occur during a transformation.
    • Add TransformationRequest for specifying the transformation options.
    • Allow multiple listeners to be registered.
    • Fix Transformer being stuck when the codec output is partially read.
    • Fix potential NPE in Transformer.getProgress when releasing the muxer throws.
    • Add a demo app for applying transformations.
  • MediaSession extension:
    • By default, MediaSessionConnector now clears the playlist on stop. Apps that want the playlist to be retained can call setClearMediaItemsOnStop(false) on the connector.
  • Cast extension:
    • Fix bug that prevented CastPlayer from calling onIsPlayingChanged correctly (#9792).
    • Support audio metadata including artwork with DefaultMediaItemConverter (#9663).
  • FFmpeg extension:
    • Make depend on LLVM's bin utils instead of GNU's (#9933).
  • Android 12 compatibility:
    • Upgrade the Cast extension to depend on Earlier versions of play-services-cast-framework are not compatible with apps targeting Android 12, and will crash with an IllegalArgumentException when creating PendingIntents (#9528).
  • Remove deprecated symbols:
    • Remove Player.EventListener. Use Player.Listener instead.
    • Remove MediaSourceFactory#setDrmSessionManager, MediaSourceFactory#setDrmHttpDataSourceFactory, and MediaSourceFactory#setDrmUserAgent. Use MediaSourceFactory#setDrmSessionManagerProvider instead.
    • Remove MediaSourceFactory#setStreamKeys. Use MediaItem.Builder#setStreamKeys instead.
    • Remove MediaSourceFactory#createMediaSource(Uri). Use MediaSourceFactory#createMediaSource(MediaItem) instead.
    • Remove setTag from DashMediaSource, HlsMediaSource and SsMediaSource. Use MediaItem.Builder#setTag instead.
    • Remove DashMediaSource#setLivePresentationDelayMs(long, boolean). Use MediaItem.Builder#setLiveConfiguration and MediaItem.LiveConfiguration.Builder#setTargetOffsetMs to override the manifest, or DashMediaSource#setFallbackTargetLiveOffsetMs to provide a fallback value.
    • Remove (Simple)ExoPlayer.setThrowsWhenUsingWrongThread. Opting out of the thread enforcement is no longer possible.
    • Remove ActionFile and ActionFileUpgradeUtil. Use ExoPlayer 2.16.1 or before to use ActionFileUpgradeUtil to merge legacy action files into DefaultDownloadIndex.
    • Remove ProgressiveMediaSource#setExtractorsFactory. Use ProgressiveMediaSource.Factory(DataSource.Factory, ExtractorsFactory) constructor instead.
    • Remove ProgressiveMediaSource.Factory#setTag and, and ProgressiveMediaSource.Factory#setCustomCacheKey. Use MediaItem.Builder#setTag and MediaItem.Builder#setCustomCacheKey instead.
    • Remove DefaultRenderersFactory(Context, @ExtensionRendererMode int) and DefaultRenderersFactory(Context, @ExtensionRendererMode int, long) constructors. Use the DefaultRenderersFactory(Context) constructor, DefaultRenderersFactory#setExtensionRendererMode, and DefaultRenderersFactory#setAllowedVideoJoiningTimeMs instead.
    • Remove all public CronetDataSource constructors. Use CronetDataSource.Factory instead.
  • Change the following IntDefs to @Target(TYPE_USE) only. This may break the compilation of usages in Kotlin, which can be fixed by moving the annotation to annotate the type (Int).

Version 1.0.0-alpha01

October 27, 2021

androidx.media3:media3-*:1.0.0-alpha01 is released. Version 1.0.0-alpha01 contains these commits.

New features

Media3 is the new home for media support libraries, including ExoPlayer. The first alpha contains early, functional implementations of libraries for implementing media use cases, including:

  • ExoPlayer, an application-level media player for Android that is easy to customize and extend.
  • Media session functionality, for exposing and controlling playbacks. This new session module uses the same Player interface as ExoPlayer.
  • UI components for building media playback user interfaces.
  • Modules wrapping functionality in other libraries for use with ExoPlayer, for example, ad insertion via the IMA SDK.

For more information, see the Media3 GitHub project.

ExoPlayer was previously hosted in a separate ExoPlayer GitHub project. In Media3 its package name is androidx.media3.exoplayer. We plan to continue to maintain and release the ExoPlayer GitHub project for a while to give apps time to migrate to Media3. Media3 has replacements for all the ExoPlayer modules, except for the legacy media2 and mediasession extensions, which are replaced by the new media3-session module. This provides direct integration between players and media sessions without needing to use an adapter/connector class.
