Release notes from ExoPlayer

r2.19.1

2023-08-16T13:49:54Z

This is the last planned release of the com.google.android.exoplayer2 artifacts. This project is now deprecated. All users should migrate to androidx.media3 (which contains the same ExoPlayer code). See the migration guide for more details, including a script to help with the migration.

This release corresponds to the AndroidX Media3 1.1.1 release.

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.

r2.19.0

2023-07-05T09:20:59Z

This release corresponds to the AndroidX Media3 1.1.0 release.

Common Library:
- Add suppression reason for unsuitable audio route and play when ready change reason for suppressed too long. (#15).
- Add commands to Player:
  - COMMAND_GET_METADATA
  - COMMAND_SET_PLAYLIST_METADATA
  - COMMAND_SET_DEVICE_VOLUME_WITH_FLAGS
  - COMMAND_ADJUST_DEVICE_VOLUME_WITH_FLAGS
- 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.
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 DefaultBandwidthMeter constructor, use DefaultBandwidthMeter.Builder instead.
- Remove DefaultDrmSessionManager constructors, use DefaultDrmSessionManager.Builder instead.

- 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 com.google.common.base.Charsets 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.
  - onDecoderInputFormatChanged, use onAudioInputFormatChanged and/or onVideoInputFormatChanged instead.
  - onDecoderDisabled, use onAudioDisabled and/or onVideoDisabled instead.
- Remove the deprecated Player.Listener.onSeekProcessed and AnalyticsListener.onSeekProcessed, use onPositionDiscontinuity with DISCONTINUITY_REASON_SEEK instead.
- Remove ExoPlayer.setHandleWakeLock(boolean), use setWakeMode(int) instead.
- Remove deprecated DefaultLoadControl.Builder.createDefaultLoadControl(), use build() instead.

r2.18.0

2022-06-27T14:56:14Z

This release corresponds to the AndroidX media3 1.0.0-beta01 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 android.media.AudioAttributes 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:
- 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 StyledPlayerView and 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 StyledPlayerView and 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 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.
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.
