1.5.0
cc8439d

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.
    • 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:
    • 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.
    • 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).
    • 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).
    • Add a setter to SntpClient to set the max elapsed time since the last update after which the client is re-initialized (#1794).
  • 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.
    • 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:
    • 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).
    • 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).
    • 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).
    • Add AC-4 Level-4 ISO base media file format support (#1265).
  • DataSource:
    • Update HttpEngineDataSource to allow use starting at version S extension 7 instead of API level 34 (#1262).
    • 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).
  • Audio:
    • Automatically configure CTA-2075 loudness metadata on the codec if present in the media.
    • Ensure smooth volume ramp down when seeking.
    • 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:
    • 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).
    • 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:
    • Add a custom VoiceSpan and populate it for WebVTT voice spans (#1632).
    • 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).
    • Support CEA-608 subtitles in Dolby Vision content (#1820).
    • Fix playback hanging on DASH multi-period streams when CEA-608 subtitles are enabled (#1863).
  • Metadata:
    • Assign the C.TRACK_TYPE_METADATA type to tracks containing icy or vnd.dvb.ait content.
  • 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.
    • Fix bug where server-side inserted DAI streams without a preroll can result in an ArrayIndexOutOfBoundsException when playing past the last midroll (#1741).
  • 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).
    • 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). there are app-defined text track selection preferences.
  • DASH Extension:
    • Add support for periods starting in the middle of a segment (#1440).
  • 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).
    • Fix crashing when parsing of RTP packets with header extensions (#1225).
  • 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.
    • 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).
  • Test Utilities:
    • DataSourceContractTest now includes tests to verify:
      • Input stream read position is updated.
      • Output buffer offset is applied correctly.
  • Demo app
    • Resolve the memory leaks in demo short-form app (#1839).
  • 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.
    • Remove deprecated DefaultEncoderFactory constructors. Use DefaultEncoderFactory.Builder instead.
