Version 1.5

1.5.0-rc01 (2024-11-13)

This release includes the following changes since the 1.5.0-beta01 release:

ExoPlayer:
- Add a setter to SntpClient to set the max elapsed time since the last update after which the client is re-initialized (#1794).
- Consider language when selecting a video track. By default select a 'main' video track that matches the language of the selected audio track, if available. Explicit video language preferences can be expressed with TrackSelectionParameters.Builder.setPreferredVideoLanguage(s).
- Add selectedAudioLanguage parameter to DefaultTrackSelector.selectVideoTrack() method.
- Add retryCount parameter to MediaSourceEventListener.onLoadStarted and corresponding MediaSourceEventListener.EventDispatcher methods.
- Fix bug where playlist items or periods in multi-period DASH streams with durations that don't match the actual content could cause frame freezes at the end of the item (#1698).
Transformer:
- Update parameters of VideoFrameProcessor.registerInputStream and VideoFrameProcessor.Listener.onInputStreamRegistered to use Format.
Extractors:
- Fix media duration parsing in mdhd box of MP4 files to handle -1 values (#1819).
- Add support for identifying h263 box in MP4 files for H.263 video (#1821).
DataSource:
- DataSourceContractTest: Assert that DataSource.getUri() returns the resolved URI (as documented). Where this is different to the requested URI, tests can indicate this using the new DataSourceContractTest.TestResource.Builder.setResolvedUri() method.
- DataSourceContractTest: Assert that DataSource.getUri() and getResponseHeaders() return their 'open' value after a failed call to open() (due to a 'not found' resource) and before a subsequent close() call.
  - Overriding DataSourceContractTest.getNotFoundResources() allows test sub-classes to provide multiple 'not found' resources, and to provide any expected headers too. This allows to distinguish between HTTP 404 (with headers) and "server not found" (no headers).
Text:
- Fix CEA-608 subtitles in H.264 MPEG-TS streams not being output (this was broken in 1.5.0-alpha01 by https://github.com/androidx/media/commit/03a205f220ecf7681f85f8a752227e3986e257ff).
- Support CEA-608 subtitles in Dolby Vision content (#1820).
RTSP Extension:
- Fix crashing when parsing of RTP packets with header extensions (#1225).

Version 1.5.0-beta01

October 30, 2024

androidx.media3:media3-*:1.5.0-beta01 is released. Version 1.5.0-beta01 contains these commits.

Common Library:
- Remove @DoNotInline annotations from manually out-of-lined inner classes designed to avoid runtime class verification failures. Recent versions of R8 now automatically out-of-line calls like these to avoid the runtime failures (so the manual out-of-lining is no longer required). All Gradle users of the library must already be a using a version of the Android Gradle Plugin that uses a version of R8 which does this, due to compileSdk = 35. Users of the library with non-Gradle build systems will need to ensure their R8-equivalent shrinking/obfuscating step does a similar automatic out-of-lining process in order to avoid runtime class verification failures. This change has already been done in other AndroidX libraries.
ExoPlayer:
- Fix MediaCodec.CryptoException sometimes being reported as an "unexpected runtime error" when MediaCodec is operated in asynchronous mode (default behaviour on API 31+).
- Pass bufferedDurationUs instead of bufferedPositionUs with PreloadMediaSource.PreloadControl.onContinueLoadingRequested(). Also changes DefaultPreloadManager.Status.STAGE_LOADED_TO_POSITION_MS to DefaultPreloadManager.Status.STAGE_LOADED_FOR_DURATION_MS, apps then need to pass a value representing a specific duration from the default start position for which the corresponding media source has to be preloaded with this IntDef, instead of a position.
- Add ForwardingRenderer implementation that forwards all method calls to another renderer (1703).
- Add playlist preloading for the next item in the playlist. Apps can enable preloading by calling ExoPlayer.setPreloadConfiguration(PreloadConfiguration) accordingly. By default preloading is disabled. When opted-in and to not interfere with playback, DefaultLoadControl restricts preloading to start and continue only when the player is not loading for playback. Apps can change this behaviour by implementing LoadControl.shouldContinuePreloading() accordingly (like when overriding this method in DefaultLoadControl). The default implementation of LoadControl disables preloading in case an app is using a custom implementation of LoadControl.
- Add method MediaSourceEventListener.EventDispatcher.dispatchEvent() to allow invoking events of subclass listeners (1736).
- Add DefaultPreloadManager.Builder that builds the DefaultPreloadManager and ExoPlayer instances with consistently shared configurations.
- Remove Renderer[] parameter from LoadControl.onTracksSelected() as DefaultLoadControl implementation can retrieve the stream types from ExoTrackSelection[].
- Deprecated DefaultLoadControl.calculateTargetBufferBytes(Renderer[], ExoTrackSelection[]) and marked method as final to prevent overrides. The new DefaultLoadControl.calculateTargetBufferBytes(ExoTrackSelection[]) should be used instead.
- Report MediaSourceEventListener events from secondary sources in MergingMediaSource. This will result in load start/error/cancelled/completed events being reported for sideloaded subtitles (those added with MediaItem.LocalConfiguration.subtitleConfigurations), which may appear as duplicate load events emitted from AnalyticsListener.
- Prevent subtitle & metadata errors from completely stopping playback. Instead the problematic track is disabled and playback of the remaining tracks continues (#1722).
  - In new subtitle handling (during extraction), associated parse (e.g. invalid subtitle data) and load errors (e.g. HTTP 404) are emitted via onLoadError callbacks.
  - In legacy subtitle handling (during rendering), only associated load errors are emitted via onLoadError callbacks while parse errors are silently ignored (this is pre-existing behaviour).
Transformer:
- Make setting the image duration using MediaItem.Builder.setImageDurationMs mandatory for image export.
- Add export support for gaps in sequences of audio EditedMediaItems.
Track Selection:
- DefaultTrackSelector: Prefer object-based audio over channel-based audio when other factors are equal.
Extractors:
- Fix preroll sample handling for non-keyframe media start positions when processing edit lists in MP4 files (#1659).
- Improved frame rate calculation by using media duration from the mdhd box in Mp4Extractor and FragmentedMp4Extractor (#1531).
- Fix incorrect scaling of media_time in MP4 edit lists. While segment_duration was already correctly scaled using the movie timescale, media_time is now properly scaled using the track timescale, as specified by the MP4 format standard (#1792).
- Handle out-of-order frames in endIndices calculation for MP4 with edit list (#1797).
Audio:
- Fix pop sounds that may occur during seeks.
- Fix truncation error accumulation for Sonic's time-stretching/pitch-shifting algorithm.
- Fix bug in SpeedChangingAudioProcessor that causes dropped output frames.
Video:
- Add workaround for a device issue on Galaxy Tab S7 FE that causes 60fps secure H264 streams to be marked as unsupported (#1619).
- Add workaround for codecs that get stuck after the last sample without returning an end-of-stream signal.
Text:
- Ensure WebVTT in HLS with very large subtitle timestamps (which overflow a 64-bit long when represented as microseconds and multiplied by the 90,000 MPEG timebase) are displayed (#1763).
Metadata:
- Assign the C.TRACK_TYPE_METADATA type to tracks containing icy or vnd.dvb.ait content.
DRM:
- Fix IllegalStateException from DefaultDrmSession.requiresSecureDecoder after opening a DRM session failed. This issue was introduced in 1.5.0-alpha01.
Muxers:
IMA extension:
- Fix bug where server-side inserted DAI streams without a preroll can result in an ArrayIndexOutOfBoundsException when playing past the last midroll (#1741).
Session:
- Fix bug that caused custom commands sent from a MediaBrowser being dispatched to the MediaSessionCompat.Callback instead of the MediaBrowserServiceCompat variant of the method when connected to a legacy service. This prevented the MediaBrowser to receive the actual return value sent back by the legacy service (#1474).
- Handle IllegalArgumentException thrown by devices of certain manufacturers when setting the broadcast receiver for media button intents (#1730).
- Add command buttons for media items. This adds the Media3 API for what was known as Custom browse actions with the legacy library with MediaBrowserCompat. Note that with Media3 command buttons for media items are available for both, MediaBrowser and MediaController. See Custom Browse actions of AAOS.
- Fix bug where a Media3 controller was sometimes unable to let a session app start a foreground service after requesting play().
- Restrict CommandButton.Builder.setIconUri to only accept content Uris.
- Pass connection hints of a Media3 browser to the initial MediaBrowserCompat when connecting to a legacy MediaBrowserCompat. The service can receive the connection hints passed in as root hints with the first call to onGetRoot().
- Fix bug where a MediaBrowser connected to a legacy browser service, didn't receive an error sent by the service after the browser has subscribed to a parentid.
- Improve interoperability behavior, so that a Media3 browser that is connected to a legacy MediaBrowserService doesn't request the children of a parentId twice when subscribing to a parent.
UI:
- Make the stretched/cropped video in PlayerView-in-Compose-AndroidView workaround opt-in, due to issues with XML-based shared transitions. Apps using PlayerView inside AndroidView need to call PlayerView.setEnableComposeSurfaceSyncWorkaround in order to opt-in (#1237, #1594).
- Add setFullscreenButtonState to PlayerView to allow updates of fullscreen button's icon on demand, i.e. out-of-band and not reactively to a click interaction (#1590, #184).
- Fix bug where the "None" choice in the text selection is not working if there are app-defined text track selection preferences.
Smooth Streaming Extension:
- Fix a Bad magic number for Bundle error when playing SmoothStreaming streams with text tracks (#1779).
RTSP Extension:
- Fix user info removal for URLs that contain encoded @ characters (#1138).
Decoder Extensions (FFmpeg, VP9, AV1, etc.):
- Add 16 KB page support for decoder extensions on Android 15 (#1685).
Cast Extension:
- Stop cleaning the timeline after the CastSession disconnects, which enables the sender app to resume playback locally after a disconnection.
- Populate CastPlayer's DeviceInfo when a Context is provided. This enables linking the MediaSession to a RoutingSession, which is necessary for integrating Output Switcher (#1056).
Remove deprecated symbols:
- Remove deprecated DefaultEncoderFactory constructors. Use DefaultEncoderFactory.Builder instead.

Version 1.5.0-alpha01

September 10, 2024

This release includes the following changes since the 1.4.1 release:

Common Library:
- Add ForwardingSimpleBasePlayer that allows forwarding to another player with small adjustments while ensuring full consistency and listener handling (#1183).
- Replace SimpleBasePlayer.State.playlist by getPlaylist() method.
- Add override for SimpleBasePlayer.State.Builder.setPlaylist() to directly specify a Timeline and current Tracks and Metadata instead of building a playlist structure.
- Increase minSdk to 21 (Android Lollipop). This is aligned with all other AndroidX libraries.
- Add androidx.media3:media3-common-ktx artifact which provides Kotlin-specific functionality built on top of the Common library
- Add Player.listen suspending extension function to spin a coroutine to listen to Player.Events to the media3-common-ktx library.
ExoPlayer:
- MediaCodecRenderer.onProcessedStreamChange() can now be called for every media item. Previously it was not called for the first one. Use MediaCodecRenderer.experimentalEnableProcessedStreamChangedAtStart() to enable this.
- Add PreloadMediaSource.PreloadControl.onPreloadError to allow PreloadMediaSource.PreloadControl implementations to take actions when error occurs.
- Add BasePreloadManager.Listener to propagate preload events to apps.
- Allow changing SNTP client timeout and retry alternative addresses on timeout (#1540).
- Remove MediaCodecAdapter.Configuration.flags as the field was always zero.
- Allow the user to select the built-in speaker for playback on Wear OS API 35+ (where the device advertises support for this).
- Defer the blocking call to Context.getSystemService(Context.AUDIO_SERVICE) until audio focus handling is enabled. This ensures the blocking call isn't done if audio focus handling is not enabled (#1616).
- Allow playback regardless of buffered duration when loading fails (#1571).
- Add AnalyticsListener.onRendererReadyChanged() to signal when individual renderers allow playback to be ready.
Transformer:
- Add SurfaceAssetLoader, which supports queueing video data to Transformer via a Surface.
- ImageAssetLoader reports unsupported input via AssetLoader.onError instead of throwing an IllegalStateException.
Extractors:
- Allow Mp4Extractor and FragmentedMp4Extractor to identify H264 samples that are not used as reference by subsequent samples.
- Add option to enable index-based seeking in AmrExtractor.
- Treat MP3 files with more than 128kB between valid frames as truncated (instead of invalid). This means files with non-MP3 data at the end, with no other metadata to indicate the length of the MP3 bytes, now stop playback at the end of the MP3 data instead of failing with ParserException: Searched too many bytes.{contentIsMalformed=true, dataType=1} (#1563).
DataSource:
- Update HttpEngineDataSource to allow use starting at version S extension 7 instead of API level 34 (#1262).
Audio:
- Automatically configure CTA-2075 loudness metadata on the codec if present in the media.
- Ensure smooth volume ramp down when seeking.
Video:
- MediaCodecVideoRenderer avoids decoding samples that are neither rendered nor used as reference by other samples.
- On API 35 and above, MediaCodecAdapter may now receive a null Surface in configure and calls to a new method detachOutputSurface to remove a previously set Surface if the codec supports this (MediaCodecInfo.detachedSurfaceSupported).
- Use MediaCodecAdapter supplied pixel aspect ratio values if provided when processing onOutputFormatChanged (#1371).
Text:
- Add a custom VoiceSpan and populate it for WebVTT voice spans (#1632).
Image:
- Add ExternallyLoadedImageDecoder for simplified integration with external image loading libraries like Glide or Coil.
DataSource:
- Add FileDescriptorDataSource, a new DataSource that can be used to read from a FileDescriptor (#3757).
Effect:
- Add DefaultVideoFrameProcessor workaround for minor SurfaceTexture scaling. SurfaceTexture may include a small scaling that cuts off a 1-texel border around the edge of a cropped buffer. This is now handled such that output is closer to expected.
- Speed up DefaultVideoFrameProcessor.queueInputBitmap(). As a result, exporting images to videos with Transformer is faster.
IMA extension:
- Fix bug where clearing the playlist may cause an ArrayIndexOutOfBoundsException in ImaServerSideAdInsertionMediaSource.
Session:
- Add MediaButtonReceiver.shouldStartForegroundService(Intent) to allow apps to suppress a play command coming in for playback resumption by overriding this method. By default, the service is always started and playback can't be suppressed without the system crashing the service with a ForegroundServiceDidNotStartInTimeException (#1528).
DASH Extension:
- Add support for periods starting in the middle of a segment (#1440).
Decoder Extensions (FFmpeg, VP9, AV1, etc.):
- Add the IAMF decoder module, which provides support for playback of MP4 files containing IAMF tracks using the libiamf native library to synthesize audio.
  - Playback is enabled with a stereo layout as well as 5.1 with spatialization together with optional head tracking enabled, but binaural playback support is currently not available.
Cast Extension:
- Stop clearning the timeline after the CastSession disconnects, which enables the sender app to resume playback locally after a disconnection.
- Populate CastPlayer's DeviceInfo when a Context is provided. This enables linking the MediaSession to a RoutingSession, which is necessary for integrating Output Switcher (#1056).
Test Utilities:
- DataSourceContractTest now includes tests to verify:
  - Input stream read position is updated.
  - Output buffer offset is applied correctly.
Remove deprecated symbols:
- Remove deprecated Player.hasPrevious, Player.hasPreviousWindow(). Use Player.hasPreviousMediaItem() instead.
- Remove deprecated Player.previous() method. Use Player.seekToPreviousMediaItem() instead.
- Remove deprecated DrmSessionEventListener.onDrmSessionAcquired method.

Version 1.4.0

Version 1.4.1

August 27, 2024

androidx.media3:media3-*:1.4.1 is released. Version 1.4.1 contains these commits.

ExoPlayer:
- Handle preload callbacks asynchronously in PreloadMediaSource (#1568).
- Allow playback regardless of buffered duration when loading fails (#1571).
Extractors:
- MP3: Fix Searched too many bytes error by correctly ignoring trailing non-MP3 data based on the length field in an Info frame (#1480).
Text:
- TTML: Fix handling of percentage tts:fontSize values to ensure they are correctly inherited from parent nodes with percentage tts:fontSize values.
- Fix IndexOutOfBoundsException in LegacySubtitleUtil due to incorrectly handling the case of the requested output start time being greater than or equal to the final event time in the Subtitle (#1516).
DRM:
- Fix android.media.MediaCodec$CryptoException: Operation not supported in this configuration: ERROR_DRM_CANNOT_HANDLE error on API 31+ devices playing L1 Widevine content. This error is caused by an incomplete implementation of the framework MediaDrm.requiresSecureDecoder method (#1603).
Effect:
- Add a release() method to GlObjectsProvider.
Session:
- Transform a double-tap of KEYCODE_HEADSETHOOK into a 'seek to next' action, as documented (#1493).
- Handle KEYCODE_HEADSETHOOK as a 'play' command in MediaButtonReceiver when deciding whether to ignore it to avoid a ForegroundServiceDidNotStartInTimeException (#1581).
RTSP Extension:
- Skip invalid Media Descriptions in SDP parsing (#1087).

Version 1.4.0

July 25, 2024

androidx.media3:media3-*:1.4.0 is released. Version 1.4.0 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).
- Add Format.customData to store app-provided custom information about Format instances.
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.
- 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.getDurationToProgressUs(). 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.
- 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).
- 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).
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.
- 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.
- 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:
- 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).
- Fix PCM audio format extraction in AVI containers.
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 issue where Listener.onRenderedFirstFrame() arrives too early when switching surfaces mid-playback.
- Fix decoder fallback logic for Dolby Vision to use a compatible AV1 decoder if needed (#1389).
- Fix codec exception that may be caused by enabling a video renderer mid-playback.
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).
- Fix an IllegalArgumentException from LegacySubtitleUtil when a WebVTT subtitle sample contains no cues, e.g. as part of a DASH stream (#1516).
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+.
- Allow null as parameter for ExoPlayer.setImageOutput() to clear a previously set ImageOutput.
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.
- 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:
- 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.
- 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.
- 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.Builder.setHdrLuminanceMultiplier().
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:
- 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.
- 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).
- 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.
- 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:
- 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).
- Work around a platform bug causing stretched/cropped video when using SurfaceView inside a Compose AndroidView on API 34 (#1237).
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).
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 (https://issuetracker.google.com/328442628).
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.
- Fix bug where non-primary playing playlists are not refreshed during live playback (#1240).
- Fix bug where enabling CMCD for HLS live streams causes ArrayIndexOutOfBoundsException (#1395).
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).
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 TestPlayerRunHelper.run(player).ignoringNonFatalErrors().untilXXX() method chain to disable this behavior.
Demo app:
- Use DefaultPreloadManager in the short form demo app.
- Allow setting repeat mode with Intent arguments from command line (#1266).
- Use HttpEngineDataSource as the HttpDataSource when supported by the device.
Remove deprecated symbols:
- Remove CronetDataSourceFactory. Use CronetDataSource.Factory instead.
- Remove some DataSpec constructors. Use DataSpec.Builder instead.
- 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 DashMediaSource.DEFAULT_LIVE_PRESENTATION_DELAY_MS. Use DashMediaSource.DEFAULT_FALLBACK_TARGET_LIVE_OFFSET_MS 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).
- 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 1.3.0

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

Version 1.1.0

Version 1.1.1

August 16, 2023

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:
  - 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.
Session:
- Add helper method MediaSession.getControllerForCurrentRequest to obtain information about the controller that is currently calling aPlayer method.
- Add androidx.media3.session.MediaButtonReceiver to enable apps to implement playback resumption with media button events sent by, for example, a Bluetooth headset (#167).
- Add default implementation to MediaSession.Callback.onAddMediaItems to allow requested MediaItems to be passed onto Player if they have LocalConfiguration (e.g. URI) (#282).
- Add "seek to previous" and "seek to next" command buttons on compact media notification view by default for Android 12 and below (#410).
- Add default implementation to MediaSession.Callback.onAddMediaItems to allow requested MediaItems to be passed onto Player if they have LocalConfiguration (e.g. URI) (#282).
- Add "seek to previous" and "seek to next" command buttons on compact media notification view by default for Android 12 and below (#410).
UI:
- Add Util methods shouldShowPlayButton and handlePlayPauseButtonAction to write custom UI elements with a play/pause button.
RTSP Extension:
- For MPEG4-LATM, use default profile-level-id value if absent in Describe Response SDP message (#302).
- Use base Uri for relative path resolution from the RTSP session if present in DESCRIBE response header (#11160).
DASH Extension:
- Remove the media time offset from MediaLoadData.startTimeMs and MediaLoadData.endTimeMs for multi period DASH streams.
- Fix a bug where re-preparing a multi-period live Dash media source produced a IndexOutOfBoundsException (#10838).
HLS Extension:
- Add HlsMediaSource.Factory.setTimestampAdjusterInitializationTimeoutMs(long) to set a timeout for the loading thread to wait for the TimestampAdjuster to initialize. If the initialization doesn't complete before the timeout, a PlaybackException is thrown to avoid the playback endless stalling. The timeout is set to zero by default (#323).
Test Utilities:
- Check for URI scheme case insensitivity in DataSourceContractTest.
Remove deprecated symbols:
- Remove DefaultAudioSink constructors, use DefaultAudioSink.Builder instead.
- Remove HlsMasterPlaylist, use HlsMultivariantPlaylist instead.
- Remove Player.stop(boolean). Use Player.stop() and Player.clearMediaItems() (if reset is true) instead.

- Remove DefaultBandwidthMeter constructor, use DefaultBandwidthMeter.Builder instead.
- Remove DefaultDrmSessionManager constructors, use DefaultDrmSessionManager.Builder instead.
- Remove two deprecated HttpDataSource.InvalidResponseCodeException constructors, use a non-deprecated constructor that accepts additional fields(cause, responseBody) to enhance error logging.
- Remove DownloadHelper.forProgressive, DownloadHelper.forHls, DownloadHelper.forDash, and DownloadHelper.forSmoothStreaming, use DownloadHelper.forMediaItem instead.
- Remove deprecated DownloadService constructor, use a non deprecated constructor that includes the option to provide a channelDescriptionResourceId parameter.
- Remove deprecated String constants for Charsets (ASCII_NAME, UTF8_NAME, ISO88591_NAME, UTF16_NAME and UTF16LE_NAME), use Kotlin Charsets from the kotlin.text package, the java.nio.charset.StandardCharsets or the 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:

  - 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.
- Remove deprecated MediaItem.PlaybackProperties, use MediaItem.LocalConfiguration instead. Deprecated field MediaItem.playbackProperties is now of type MediaItem.LocalConfiguration.

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 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:
- 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.

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

Version 1.0.0-alpha02

March 2, 2022

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

This corresponds to the ExoPlayer 2.17.0 release.

Core Library:
- Add protected method DefaultRenderersFactory.getCodecAdapterFactory() so that subclasses of DefaultRenderersFactory that override buildVideoRenderers() or buildAudioRenderers() can access the codec adapter factory and pass it to MediaCodecRenderer instances they create.
- Propagate ICY header fields name and genre to MediaMetadata.station and MediaMetadata.genre respectively so that they reach the app via Player.Listener.onMediaMetadataChanged() (#9677).
- Remove null keys from DefaultHttpDataSource#getResponseHeaders.
- Sleep and retry when creating a MediaCodec instance fails. This works around an issue that occurs on some devices when switching a surface from a secure codec to another codec (#8696).
- Add MediaCodecAdapter.getMetrics() to allow users obtain metrics data from MediaCodec. (#9766).
- Fix Maven dependency resolution (#8353).
- Disable automatic speed adjustment for live streams that neither have low-latency features nor a user request setting the speed (#9329).
- Rename DecoderCounters#inputBufferCount to queuedInputBufferCount.
- Make SimpleExoPlayer.renderers private. Renderers can be accessed via ExoPlayer.getRenderer.
- Updated some AnalyticsListener.EventFlags constant values to match values in Player.EventFlags.
- Split AnalyticsCollector into an interface and default implementation to allow it to be stripped by R8 if an app doesn't need it.
Track selection:
- Support preferred video role flags in track selection (#9402).
- Update video track selection logic to take preferred MIME types and role flags into account when selecting multiple video tracks for adaptation (#9519).
- Update video and audio track selection logic to only choose formats for adaptive selections that have the same level of decoder and hardware support (#9565).
- Update video track selection logic to prefer more efficient codecs if multiple codecs are supported by primary, hardware-accelerated decoders (#4835).
- Prefer audio content preferences (for example, the "default" audio track or a track matching the system locale language) over technical track selection constraints (for example, preferred MIME type, or maximum channel count).
- Fix track selection issue where overriding one track group did not disable other track groups of the same type (#9675).
- Fix track selection issue where a mixture of non-empty and empty track overrides is not applied correctly (#9649).
- Prohibit duplicate TrackGroups in a TrackGroupArray. TrackGroups can always be made distinguishable by setting an id in the TrackGroup constructor. This fixes a crash when resuming playback after backgrounding the app with an active track override (#9718).
- Amend logic in AdaptiveTrackSelection to allow a quality increase under sufficient network bandwidth even if playback is very close to the live edge (#9784).
Video:
- Fix decoder fallback logic for Dolby Vision to use a compatible H264/H265 decoder if needed.
Audio:
- 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 MediaItem.SubtitleConfiguration.id field which is propagated to the Format.id 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 build_ffmpeg.sh depend on LLVM's bin utils instead of GNU's (#9933).
Android 12 compatibility:
- Upgrade the Cast extension to depend on com.google.android.gms:play-services-cast-framework:20.1.0. 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.
