1.4.0
b01c6ff

This release includes the following changes since the 1.3.1 release:

  • 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 (https://developer.android.com/media/media3/exoplayer/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 (https://issues/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.
