Version 1.4.0

Version 1.4.0-rc01

July 10, 2024

androidx.media3:media3-*:1.4.0-rc01 is released. Version 1.4.0-rc01 contains these commits.

  • Common Library:
    • Add Format.customData to store app-provided custom information about Format instances.
  • ExoPlayer:
    • Fix some audio focus inconsistencies, e.g. not reporting full or transient focus loss while the player is paused (#1436).
    • Fix potential IndexOutOfBoundsException caused by extractors reporting additional tracks after the initial preparation step (#1476).
    • Effects in ExoPlayer.setVideoEffect() will receive the timestamps with the renderer offset removed (#1098).
    • Fix potential IllegalArgumentException when handling player error that happened while reading ahead into another playlist item (#1483).
  • Text:
    • Fix an IllegalArgumentException from LegacySubtitleUtil when a WebVTT subtitle sample contains no cues, e.g. as part of a DASH stream (#1516).
  • Session:
    • Allow the session activity to be set per controller to override the global session activity. The session activity can be defined for a controller at connection time by creating a ConnectionResult with AcceptedResultBuilder.setSessionActivivty(PendingIntent). Once connected, the session activity can be updated with MediaSession.setSessionActivity(ControllerInfo, PendingIntent).
    • Improve error replication of calls to MediaLibrarySession.Callback. Error replication can now be configured by using MediaLibrarySession.Builder.setLibraryErrorReplicationMode() for choosing the error type or opt-ing out of error replication which is on by default.
  • UI:
    • Work around a platform bug causing stretched/cropped video when using SurfaceView inside a Compose AndroidView on API 34 (#1237).
  • Demo app:
    • Use HttpEngineDataSource as the HttpDataSource when supported by the device.

Version 1.4.0-beta01

June 26, 2024

androidx.media3:media3-*:1.4.0-beta01 is released. Version 1.4.0-beta01 contains these commits.

  • ExoPlayer:
    • Add ExoPlayer.isReleased() to check whether Exoplayer.release() has been called.
    • Add ExoPlayer.Builder.setMaxSeekToPreviousPositionMs to configure the maximum position for which seekToPrevious() seeks to the previous item (#1425).
  • Transformer:
    • Remove ExportResult.processedInputs field. If you use this field for codec details, then use DefaultDecoderFactory.listener instead. In case of a codec exception, codec details will be available in the ExportException.codecInfo.
  • Extractors:
    • Fix PCM audio format extraction in AVI containers.
  • Image:
    • Allow null as parameter for ExoPlayer.setImageOutput to clear a previously set ImageOutput.
  • Effect:
    • Remove unused OverlaySettings.useHdr since dynamic range of overlay and frame must match.
    • Add HDR support for TextOverlay. Luminance of the text overlay can be adjusted with OverlaySettings.setHdrLuminanceMultiplier.
  • Session:
    • Add MediaSession.Callback.onPlayerInteractionFinished to inform sessions when a series of player interactions from a specific controller finished.
    • Add SessionError and use it in SessionResult and LibraryResult instead of the error code to provide more information about the error and how to resolve the error if possible.
    • Publish the code for the media3 controller test app that can be used to test interactions with apps publishing a media session.
    • Propagate extras passed to media3's MediaSession[Builder].setSessionExtras() to a media1 controller's PlaybackStateCompat.getExtras().
    • Map fatal and non-fatal errors to and from the platform session. A PlaybackException is mapped to a fatal error state of the PlaybackStateCompat. A SessionError sent to the media notification controller with MediaSession.sendError(ControllerInfo, SessionError) is mapped to a non-fatal error in PlaybackStateCompat which means that error code and message are set but the state of the platform session remains different to STATE_ERROR.
  • UI:
    • Add image display support to PlayerView when connected to an ExoPlayer (#1144).
    • Add customization of various icons in PlayerControlView through xml attributes to allow different drawables per PlayerView instance, rather than global overrides (#1200).
  • HLS Extension:
    • Fix a bug where non-primary playing playlists are not refreshed during live playback (#1240).
  • Remove deprecated symbols:
    • Remove Bundleable interface. This includes removing all Bundleable.Creator<Foo> CREATOR constant fields. Callers should use the Bundle toBundle() and static Foo fromBundle(Bundle) methods on each type instead.

Version 1.4.0-alpha02

June 07, 2024

androidx.media3:media3-*:1.4.0-alpha02 is released. Version 1.4.0-alpha02 contains these commits.

  • Common Library:
    • Forward presumed no-op seek calls to the protected BasePlayer.seekTo and SimpleBasePlayer.handleSeek methods instead of ignoring them. If you are implementing these methods in a custom player, you may need to handle these additional calls with mediaItemIndex == C.INDEX_UNSET.
    • Remove compile dependency on enhanced Java 8 desugaring (#1312).
    • Ensure the duration passed to MediaItem.Builder.setImageDurationMs is ignored for a non-image MediaItem (as documented).
  • ExoPlayer:
    • Add reset to BasePreloadManager to release all the holding sources while keep the preload manager instance.
    • Add ExoPlayer.setPriority (and Builder.setPriority) to define the priority value used in PriorityTaskManager and for MediaCodec importance from API 35.
    • Fix issue with updating the last rebuffer time which resulted in incorrect bs (buffer starvation) key in CMCD (#1124).
    • Add PreloadMediaSource.PreloadControl.onLoadedToTheEndOfSource(PreloadMediaSource) to indicate that the source has loaded to the end. This allows the DefaultPreloadManager and the custom PreloadMediaSource.PreloadControl implementations to preload the next source or take other actions.
    • Fix bug where silence skipping at the end of items can trigger a playback exception.
    • Add clear to PreloadMediaSource to discard the preloading period.
    • Add new error code PlaybackException.ERROR_CODE_DECODING_RESOURCES_RECLAIMED that is used when codec resources are reclaimed for higher priority tasks.
    • Let AdsMediaSource load preroll ads before initial content media preparation completes (#1358).
    • Fix bug where playback moved to STATE_ENDED when re-preparing a multi-period DASH live stream after the original period was already removed from the manifest.
    • Rename onTimelineRefreshed to onSourcePrepared and onPrepared to onTracksSelected in PreloadMediaSource.PreloadControl. Also rename the IntDefs in DefaultPreloadManager.Stage accordingly.
    • Add experimental support for dynamic scheduling to better align work with CPU wake-cycles and delay waking up to when renderers can progress. You can enable this using experimentalSetDynamicSchedulingEnabled when setting up your ExoPlayer instance.
    • Add Renderer.getDurationToProgressMs. A Renderer can implement this method to return to ExoPlayer the duration that playback must advance for the renderer to progress. If ExoPlayer is set with experimentalSetDynamicSchedulingEnabled then ExoPlayer will call this method when calculating the time to schedule its work task.
    • Add MediaCodecAdapter#OnBufferAvailableListener to alert when input and output buffers are available for use by MediaCodecRenderer. MediaCodecRenderer will signal ExoPlayer when receiving these callbacks and if ExoPlayer is set with experimentalSetDynamicSchedulingEnabled, then ExoPlayer will schedule its work loop as renderers can make progress.
    • Use data class for LoadControl methods instead of individual parameters.
  • Transformer:
    • Work around a decoder bug where the number of audio channels was capped at stereo when handling PCM input.
    • When selecting tracks in ExoPlayerAssetLoader, ignore audio channel count constraints as they only apply for playback.
    • Replace androidx.media3.transformer.Muxer interface with androidx.media3.muxer.Muxer and remove androidx.media3.transformer.Muxer.
    • Fix HEIC image loading from content URI schemes. (#1373).
    • Adjust audio track duration in AudioGraphInput to improve AV sync.
  • Extractors:
    • MPEG-TS: Roll forward the change ensuring the last frame is rendered by passing the last access unit of a stream to the sample queue (#7909). Incorporating fixes to resolve the issues that emerged in I-frame only HLS streams(#1150) and H.262 HLS streams (#1126).
    • MP3: Prefer the data size from an Info frame over the size reported by the underlying stream (e.g. file size, or HTTP Content-Length header). This helps to exclude non-playable trailer data (e.g. album artwork) from constant bitrate seeking calculations, making seeks more accurate (#1376).
    • MP3: Use the frame count and other data in an Info frame (if present) to compute an average bitrate for constant bitrate seeking, rather than extrapolating from the bitrate of the frame after the Info frame, which may be artificially small, e.g. PCUT frame (#1376).
  • Audio:
    • Fix DTS:X Profile 2 encoding attributes for passthrough playback (#1299).
    • For offloaded playback, reset the tracking field for stream completion in DefaultAudioSink prior to calling AudioTrack.stop() so that AudioTrack.StreamEventCallback#onPresentationEnded correctly identifies when all pending data has been played.
    • Fix bug in SilenceSkippingAudioProcessor where transitions between different audio formats (for example stereo to mono) can cause the processor to throw an exception (#1352).
    • Implement MediaCodecAudioRenderer.getDurationToProgressUs so that ExoPlayer will dynamically schedule its main work loop to when the MediaCodecAudioRenderer can make progress.
  • Video:
    • Fix decoder fallback logic for Dolby Vision to use a compatible AV1 decoder if needed (#1389).
  • Text:
    • Fix issue where subtitles starting before a seek position are skipped. This issue was only introduced in Media3 1.4.0-alpha01.
    • Change default subtitle parsing behavior so it happens during extraction instead of during rendering (see ExoPlayer's architecture diagram for the difference between extraction and rendering).
      • This change can be overridden by calling both MediaSource.Factory.experimentalParseSubtitlesDuringExtraction(false) and TextRenderer.experimentalSetLegacyDecodingEnabled(true). See the docs on customization for how to plumb these components into an ExoPlayer instance. These methods (and all support for legacy subtitle decoding) will be removed in a future release.
      • Apps with custom SubtitleDecoder implementations need to update them to implement SubtitleParser instead (and SubtitleParser.Factory instead of SubtitleDecoderFactory).
    • PGS: Fix run-length decoding to resolve 0 as a color index, instead of a literal color value (#1367).
    • CEA-708: Ignore rowLock value. The CEA-708-E S-2023 spec states that rowLock and columnLock should both be assumed to be true, regardless of the values present in the stream (columnLock support is not implemented, so it's effectively assumed to always be false).
      • This was originally included in the 1.3.0-alpha01 release notes, but the change was accidentally reverted before the 1.3.0-rc01 release. This is now fixed, so the change is present again.
    • CEA-708: Avoid duplicate newlines being added by ExoPlayer's naive handling of the 'set pen location' command (#1315).
  • Metadata:
    • Fix mapping of MP4 to ID3 sort tags. Previously the 'album sort' (soal), 'artist sort' (soar) and 'album artist sort' (soaa) MP4 tags were wrongly mapped to the TSO2, TSOA and TSOP ID3 tags (#1302).
    • Fix reading of MP4 (/iTunes) numeric gnre (genre) and tmpo (tempo) tags when the value is more than one byte long.
    • Propagate ID3 TCON frame to MediaMetadata.genre (#1305).
  • Image:
    • Add support for non-square DASH thumbnail grids (#1300).
    • Add support for AVIF for API 34+.
  • DataSource:
    • Allow ByteArrayDataSource to resolve a URI to a byte array during open(), instead of being hard-coded at construction (#1405).
  • DRM:
    • Allow setting a LoadErrorHandlingPolicy on DefaultDrmSessionManagerProvider (#1271).
  • Effect:
    • Fix bug where TimestampWrapper crashes when used with ExoPlayer#setVideoEffects (#821).
    • Change default SDR color working space from linear colors to electrical BT 709 SDR video. Also provide third option to retain the original colorspace.
    • Allow defining indeterminate z-order of EditedMediaItemSequences (#1055).
    • Maintain a consistent luminance range across different pieces of HDR content (uses the HLG range).
    • Add support for Ultra HDR (bitmap) overlays on HDR content.
    • Allow SeparableConvolution effects to be used before API 26.
  • IMA extension:
    • Promote API that is required for apps to play DAI ad streams to stable.
    • Add replaceAdTagParameters(Map <String, String>) to ImaServerSideAdInsertionMediaSource.AdLoader that allows replacing ad tag parameters at runtime.
    • Fix bug where VideoAdPlayer.VideoAdPlayerCallback.onError was not called when a player error happened during ad playback (#1334).
    • Bump IMA SDK version to 3.33.0 to fix a NullPointerException when using data:// ad tag URIs (#700).
  • Session:
    • Hide seekbar in the media notification for live streams by not setting the duration into the platform session metadata (#1256).
    • Align conversion of MediaMetadata to MediaDescriptionCompat, to use the same preferred order and logic when selecting metadata properties as in media1.
    • Add MediaSession.sendError() that allows sending non-fatal errors to Media3 controller. When using the notification controller (see MediaSession.getMediaNotificationControllerInfo()), the custom error is used to update the PlaybackState of the platform session to an error state with the given error information (#543).
  • Cronet Extension:
    • Fix SocketTimeoutException in CronetDataSource. In some versions of Cronet, the request provided by the callback is not always the same. This leads to callback not completing and request timing out (
  • HLS Extension:
    • Fix bug where pending EMSG samples waiting for a discontinuity were delegated in HlsSampleStreamWrapper with an incorrect offset causing an IndexOutOfBoundsException or an IllegalArgumentException (#1002).
    • Fix bug where non-primary playlists keep reloading for LL-HLS streams (#1240).
    • Fix bug where enabling CMCD for HLS with initialization segments resulted in Source Error and IllegalArgumentException.
  • DASH Extension:
    • Fix bug where re-preparing a multi-period live stream can throw an IndexOutOfBoundsException (#1329).
    • Add support for dashif:Laurl license urls (#1345).
  • Cast Extension:
    • Fix bug that converted the album title of the MediaQueueItem to the artist in the Media3 media item (#1255).
  • Demo app:
    • Allow setting repeat mode with Intent arguments from command line (#1266).
  • Remove deprecated symbols:
    • Remove setContentTypePredicate(Predicate) method from DefaultHttpDataSource, OkHttpDataSource and CronetDataSource. Use the equivalent method on each XXXDataSource.Factory instead.
    • Remove OkHttpDataSource constructors and OkHttpDataSourceFactory. Use OkHttpDataSource.Factory instead.
    • Remove PlayerMessage.setHandler(Handler). Use setLooper(Looper) instead.
    • Remove Timeline.Window.isLive field. Use the isLive() method instead.
    • Remove DefaultHttpDataSource constructors. Use DefaultHttpDataSource.Factory instead.
    • Remove MediaCodecInfo.isSeamlessAdaptationSupported(Format, Format, boolean). Use MediaCodecInfo.canReuseCodec(Format, Format) instead.
    • Remove DrmSessionManager.DUMMY and getDummyDrmSessionManager() method. Use DrmSessionManager.DRM_UNSUPPORTED instead.
    • Remove AnalyticsListener.onAudioInputFormatChanged(EventTime, Format), AnalyticsListener.onVideoInputFormatChanged(EventTime, Format), AudioRendererEventListener.onAudioInputFormatChanged(Format), VideoRendererEventListener.onVideoInputFormatChanged(Format). Use the overloads that take a DecoderReuseEvaluation instead.
    • Remove RendererSupport.FormatSupport IntDef and FORMAT_HANDLED, FORMAT_EXCEEDS_CAPABILITIES, FORMAT_UNSUPPORTED_DRM, FORMAT_UNSUPPORTED_SUBTYPE, FORMAT_UNSUPPORTED_TYPE constants. Use the equivalent IntDef and constants in androidx.media3.common.C instead (e.g. C.FORMAT_HANDLED).

Version 1.4.0-alpha01

April 17, 2024

androidx.media3:media3-*:1.4.0-alpha01 is released. Version 1.4.0-alpha01 contains these commits.

  • ExoPlayer:
    • Add BasePreloadManager which coordinates the preloading for multiple sources based on the priorities defined by their rankingData. Customization is possible by extending this class. Add DefaultPreloadManager which uses PreloadMediaSource to preload media samples of the sources into memory, and uses an integer rankingData that indicates the index of an item on the UI.
    • Add PlayerId to most methods of LoadControl to enable LoadControl implementations to support multiple players.
    • Remove Buffer.isDecodeOnly() and C.BUFFER_FLAG_DECODE_ONLY. There is no need to set this flag as renderers and decoders will decide to skip buffers based on timestamp. Custom Renderer implementations should check if the buffer time is at least BaseRenderer.getLastResetPositionUs() to decide whether a sample should be shown. Custom SimpleDecoder implementations can check isAtLeastOutputStartTimeUs if needed or mark other buffers with DecoderOutputBuffer.shouldBeSkipped to skip them.
    • Allow a null value to be returned by TargetPreloadStatusControl.getTargetPreloadStatus(T) to indicate not to preload a MediaSource with the given rankingData.
    • Add remove(MediaSource) to BasePreloadManager.
  • Transformer:
    • Add audioConversionProcess and videoConversionProcess to ExportResult indicating how the respective track in the output file was made.
    • Relax trim optimization H.264 level checks.
    • Add support for changing between SDR and HDR input media in a sequence.
    • Add support for composition-level audio effects.
    • Add support for transcoding Ultra HDR images into HDR videos.
    • Fix issue where the DefaultAudioMixer does not output the correct amount of bytes after being reset and reused.
  • Video:
    • Fix issue where Listener.onRenderedFirstFrame() arrives too early when switching surfaces mid-playback.
  • DataSource:
    • Implement support for android.resource://package/id raw resource URIs where package is different to the package of the current application. This wasn't previously documented to work, but is a more efficient way of accessing resources in another package than by name.
    • Eagerly check url is non-null in the DataSpec constructors. This parameter was already annotated to be non-null.
  • Effect:
    • Support multiple speed changes within the same EditedMediaItem or Composition in SpeedChangeEffect.
    • Support for HLG and PQ output from ultra HDR bitmap input.
    • Add support for EGL_GL_COLORSPACE_BT2020_HLG_EXT, which improves HLG surface output in ExoPlayer.setVideoEffect and Transformer's Debug SurfaceView.
    • Update Overlay matrix implementation to make it consistent with the documentation by flipping the x and y values applied in setOverlayFrameAnchor(). If using OverlaySettings.Builder.setOverlayFrameAnchor(), flip their x and y values by multiplying them by -1.
  • Session:
    • Change default of CommandButton.enabled to true and ensure the value can stay false for controllers even if the associated command is available.
    • Add icon constants for CommandButton that should be used instead of custom icon resources.
    • Add MediaSessionService.isPlaybackOngoing() to let apps query whether the service needs to be stopped in onTaskRemoved() (#1219).
    • Add MediaSessionService.pauseAllPlayersAndStopSelf() that conveniently allows to pause playback of all sessions and call stopSelf to terminate the lifecycle of the MediaSessionService.
    • Override MediaSessionService.onTaskRemoved(Intent) to provide a safe default implementation that keeps the service running in the foreground if playback is ongoing or stops the service otherwise.
  • Downloads:
    • Ensure that DownloadHelper does not leak unreleased Renderer instances, which can eventually result in an app crashing with IllegalStateException: Too many receivers, total of 1000, registered for pid (#1224).
  • Test Utilities:
    • Implement onInit() and onRelease() in FakeRenderer.
    • Change TestPlayerRunHelper.runUntil/playUntil methods to fail on nonfatal errors (e.g. those reported to AnalyticsListener.onVideoCodecError). Use the new method chain to disable this behavior.
  • Demo app:
    • Use DefaultPreloadManager in the short form demo app.
  • Remove deprecated symbols:
    • Remove CronetDataSourceFactory. Use CronetDataSource.Factory instead.
    • Remove some DataSpec constructors. Use DataSpec.Builder instead.

Version 1.3.0

Version 1.3.1

April 11, 2024

androidx.media3:media3-*:1.3.1 is released. Version 1.3.1 contains these commits.

  • Common Library:
    • Add Format.labels to allow localized or other alternative labels.
  • ExoPlayer:
    • Fix issue where PreloadMediaPeriod cannot retain the streams when it is preloaded again.
    • Apply the correct corresponding TrackSelectionResult to the playing period in track reselection.
    • Start early-enabled renderers only after advancing the playing period when transitioning between media items (#1017).
    • Add missing return type to proguard -keepclasseswithmembers rule for (#1187).
  • Transformer:
    • Add workaround for exception thrown due to MediaMuxer not supporting negative presentation timestamps before API 30.
  • Track Selection:
    • DefaultTrackSelector: Prefer video tracks with a 'reasonable' frame rate (>=10fps) over those with a lower or unset frame rate. This ensures the player selects the 'real' video track in MP4s extracted from motion photos that can contain two HEVC tracks where one has a higher resolution but a very small number of frames (#1051).
  • Extractors:
    • Fix issue where padding was not skipped when reading odd-sized chunks from WAV files (#1117).
    • MP3: Populate Format.averageBitrate from metadata frames such as XING and VBRI.
    • MPEG-TS: Revert a change that aimed to ensure the last frame is rendered by passing the last access unit of a stream to the sample queue (#7909). This is due to the change causing new problems with I-frame only HLS streams (#1150) and H.262 HLS streams (#1126).
  • Audio:
    • Allow renderer recovery by disabling offload if audio track fails to initialize in offload mode.
  • Video:
    • Add workaround for a device issue on Galaxy Tab S7 FE, Chromecast with Google TV, and Lenovo M10 FHD Plus that causes 60fps H265 streams to be marked as unsupported
    • Add workaround that ensures the first frame is always rendered while tunneling even if the device does not do this automatically as required by the API (#1169). (#966).
    • Fix issue where HDR color info handling causes codec misbehavior and prevents adaptive format switches for SDR video tracks (#1158).
  • Text:
    • WebVTT: Prevent directly consecutive cues from creating spurious additional CuesWithTiming instances from WebvttParser.parse (#1177).
  • DRM:
    • Work around a NoSuchMethodError which can be thrown by the MediaDrm framework instead of ResourceBusyException or NotProvisionedException on some Android 14 devices (#1145).
  • Effect:
    • Improved PQ to SDR tone-mapping by converting color spaces.
  • Session:
    • Fix issue where the current position jumps back when the controller replaces the current item (#951).
    • Fix issue where MediaMetadata with just non-null extras is not transmitted between media controllers and sessions (#1176).
  • UI:
    • Fallback to include audio track language name if Locale cannot identify a display name (#988).
  • DASH Extension:
    • Populate all Label elements from the manifest into Format.labels (#1054).
  • RTSP Extension:
    • Skip empty session information values (i-tags) in SDP parsing (#1087).
  • Decoder Extensions (FFmpeg, VP9, AV1, MIDI, etc.):
    • Disable the MIDI extension as a local dependency by default because it requires an additional Maven repository to be configured. Users who need this module from a local dependency can re-enable it.

Version 1.3.0

March 6, 2024

androidx.media3:media3-*:1.3.0 is released. Version 1.3.0 contains these commits.

  • Common Library:
    • Implement support for android.resource://package/[type/]name raw resource URIs where package is different to the package of the current application. This has always been documented to work, but wasn't correctly implemented until now.
    • Normalize MIME types set by app code or read from media to be fully lower-case.
    • Define ads with a full MediaItem instead of a single Uri in AdPlaybackState.
    • Increase minSdk to 19 (Android KitKat). This is aligned with all other AndroidX libraries, and is required for us to upgrade to the latest versions of our AndroidX dependencies.
    • Populate both artworkUri and artworkData in MediaMetadata.Builder.populate(MediaMetadata) when at least one of them is non-null (#964).
  • ExoPlayer:
    • Add PreloadMediaSource and PreloadMediaPeriod that allows apps to preload a content media source at a specific start position before playback. PreloadMediaSource takes care of preparing the content media source to receive the Timeline, preparing and caching the period at the given start position, selecting tracks and loading media data for the period. Apps control the preload progress by implementing PreloadMediaSource.PreloadControl and set the preloaded source to the player for playback.
    • Add ExoPlayer.setImageOutput that allows apps to set ImageRenderer.ImageOutput.
    • DefaultRenderersFactory now provides an ImageRenderer to the player by default with null ImageOutput and ImageDecoder.Factory.DEFAULT.
    • Emit Player.Listener.onPositionDiscontinuity event when silence is skipped (#765).
    • Add experimental support for parsing subtitles during extraction. You can enable this using MediaSource.Factory.experimentalParseSubtitlesDuringExtraction().
    • Support adaptive media sources with PreloadMediaSource.
    • Implement HttpEngineDataSource, an HttpDataSource using the HttpEngine API.
    • Prevent subclassing CompositeSequenceableLoader. This component was previously made extensible but was never subclassed within the library. Customizations can be done by wrapping an instance using the decorator pattern and implementing a custom CompositeSequenceableLoaderFactory.
    • Fix issue where repeating the same time causes metadata from this item to be cleared (#1007).
    • Rename experimentalSetSubtitleParserFactory methods on BundledChunkExtractor.Factory and DefaultHlsExtractorFactory to setSubtitleParserFactory and disallow passing null. Use the new experimentalParseSubtitlesDuringExtraction(boolean) methods to control parsing behaviour.
    • Add support for customising the SubtitleParser.Factory used during extraction. This can be achieved with MediaSource.Factory.setSubtitleParserFactory().
    • Add source prefix to all fields generated from MergingMediaSource. This helps to identify which source produced a Format (#883).
    • Fix the regex used for validating custom Common Media Client Data (CMCD) key names by modifying it to only check for hyphen (#1028).
    • Stop double-encoding CMCD query parameters (#1075).
  • Transformer:
    • Add support for flattening H.265/HEVC SEF slow motion videos.
    • Increase transmuxing speed, especially for 'remove video' edits.
    • Add API to ensure that the output file starts on a video frame. This can make the output of trimming operations more compatible with player implementations that don't show the first video frame until its presentation timestamp (#829).
    • Add support for optimizing single asset MP4 trim operations.
    • Add support to ensure a video frame has the first timestamp in the output file. Fixes output files beginning with black frame on iOS based players (#829).
  • Track Selection:
    • Add DefaultTrackSelector.selectImageTrack to enable image track selection.
    • Add TrackSelectionParameters.isPrioritizeImageOverVideoEnabled to determine whether to select an image track if both an image track and a video track are available. The default value is false which means selecting a video track is prioritized.
  • Extractors:
    • Add additional AV1C parsing to MP4 extractor to retrieve ColorInfo.colorSpace, ColorInfo.colorTransfer, and ColorInfo.colorRange values (#692).
    • MP3: Use constant bitrate (CBR) seeking for files with an Info header (the CBR equivalent of the Xing header). Previously we used the seek table from the Info header, but this results in less precise seeking than if we ignore it and assume the file is CBR.
    • MPEG2-TS: Add DTS, DTS-LBR and DTS:X Profile2 support (#275).
    • Extract audio types from TS descriptors and map them to role flags, allowing users to make better-informed audio track selections (#973).
  • Audio:
    • Improve silence skipping algorithm with smooth volume ramp; retained minimal silence and more natural silence durations (#7423).
    • Report the skipped silence more deterministically (#1035).
  • Video:
    • Change the MediaCodecVideoRenderer constructor that takes a VideoFrameProcessor.Factory argument and replace it with a constructor that takes a VideoSinkProvider argument. Apps that want to inject a custom VideoFrameProcessor.Factory can instantiate a CompositingVideoSinkProvider that uses the custom VideoFrameProcessor.Factory and pass the video sink provider to MediaCodecVideoRenderer.
  • Text:
    • Fix serialization of bitmap cues to resolve Tried to marshall a Parcel that contained Binder objects error when using DefaultExtractorsFactory.setTextTrackTranscodingEnabled (#836).
    • CEA-708: Ignore rowLock value. The CEA-708-E S-2023 spec states that rowLock and columnLock should both be assumed to be true, regardless of the values present in the stream (columnLock support is not implemented, so it's effectively assumed to always be false).
  • Image:
    • Add support for DASH thumbnails. Grid images are cropped and individual thumbnails are provided to ImageOutput close to their presentation times.
  • DRM:
  • IMA extension:
    • Fix issue where DASH and HLS ads without the appropriate file extension can't be played.
  • Session:
    • Disable double-click detection for TV apps (#962).
    • Fix issue where MediaItem.RequestMetadata with just non-null extras is not transmitted between media controllers and sessions.
    • Add constructor to MediaLibrarySession.Builder that only takes a Context instead of a MediaLibraryService.
  • HLS Extension:
    • Reduce HlsMediaPeriod to package-private visibility. This type shouldn't be directly depended on from outside the HLS package.
    • Resolve seeks to beginning of a segment more efficiently (#1031).
  • Decoder Extensions (FFmpeg, VP9, AV1, MIDI, etc.):
    • MIDI decoder: Ignore SysEx event messages (#710).
  • Test Utilities:
    • Don't pause playback in TestPlayerRunHelper.playUntilPosition. The test keeps the playback in a playing state, but suspends progress until the test is able to add assertions and further actions.
  • Demo app:
    • Add a shortform demo module to demo the usage of PreloadMediaSource with the short-form content use case.

Version 1.2.0

Version 1.2.1

January 9, 2024

  • ExoPlayer:
    • Fix issue where manual seeks outside of the LiveConfiguration.min/maxOffset range keep adjusting the offset back to min/maxOffset.
    • Fix issue that OPUS and VORBIS channel layouts are wrong for 3, 5, 6, 7 and 8 channels (#8396).
    • Fix issue where track selections after seek to zero in a live stream incorrectly let the stream start at its default position (#9347).
    • Fix the issue where new instances of CmcdData.Factory were receiving negative values for bufferedDurationUs from chunk sources, resulting in an IllegalArgumentException (#888).
  • Transformer:
    • Work around an issue where the encoder would throw at configuration time due to setting a high operating rate.
  • Extractors:
    • Mark secondary (unplayable) HEVC tracks in JPEG motion photos as ROLE_FLAG_ALTERNATE to prevent them being automatically selected for playback because of their higher resolution.
    • Fix wrong keyframe detection for TS H264 streams (#864).
    • Fix duration estimation of TS streams that are longer than 47721 seconds (#855).
  • Audio:
    • Fix handling of EOS for SilenceSkippingAudioProcessor when called multiple times (#712).
  • Video:
    • Add workaround for a device issue on Galaxy Tab S7 FE, Chromecast with Google TV, and Lenovo M10 FHD Plus that causes 60fps AVC streams to be marked as unsupported (#693).
  • Metadata:
    • Fix bug where MediaMetadata was only populated from Vorbis comments with upper-case keys (#876).
    • Catch OutOfMemoryError when parsing very large ID3 frames, meaning playback can continue without the tag info instead of playback failing completely.
  • DRM:
    • Extend workaround for spurious ClearKey https://default.url license URL to API 33+ (previously the workaround only applied on API 33 exactly) (#837).
    • Fix ERROR_DRM_SESSION_NOT_OPENED when switching from encrypted to clear content without a surface attached to the player. The error was due to incorrectly using a secure decoder to play the clear content.
  • Session:
    • Put the custom keys and values in MediaMetadataCompat to MediaMetadata.extras and MediaMetadata.extras to MediaMetadataCompat (#756, #802).
    • Fix broadcasting notifyChildrenChanged for legacy controllers (#644).
    • Fix a bug where setting a negative time for a disabled setWhen timer of the notification caused a crash on some devices (#903).
    • Fix IllegalStateException when the media notification controller hasn't completed connecting when the first notification update is requested (#917).
  • UI:
    • Fix issue where forward and rewind buttons are not visible when used with Material Design in a BottomSheetDialogFragment (#511).
    • Fix issue where the numbers in the fast forward button of the PlayerControlView were misaligned (#547).
  • DASH Extension:
    • Parse "f800" as channel count of 5 for Dolby in DASH manifest (#688).
  • Decoder Extensions (FFmpeg, VP9, AV1, MIDI, etc.):
    • MIDI: Fix issue where seeking forward skips the Program Change events (#704).
    • Migrate to FFmpeg 6.0 and update supported NDK to r26b (#707, #867).
  • Cast Extension:
    • Sanitize creation of a Timeline to not crash the app when loading media fails on the cast device (#708).

Version 1.2.0

November 15, 2023

  • 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
    • 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).
    • 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 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.

  • 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

July 5, 2023

  • 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:

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-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:
    • Fix decoder fallback logic for Dolby Atmos (E-AC3-JOC) to use a compatible E-AC3 decoder if needed.
    • Change AudioCapabilities APIs to require passing explicitly AudioCapabilities.DEFAULT_AUDIO_CAPABILITIES instead of null.
    • Allow customization of the AudioTrack buffer size calculation by injecting an AudioTrackBufferSizeProvider to DefaultAudioSink. (#8891).
    • Retry AudioTrack creation if the requested buffer size was > 1MB. (#9712).
  • 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.
