r2.18.0

This release corresponds to the AndroidX media3 1.0.0-beta01 release.

• Core library:
  • Enable support for Android platform diagnostics via MediaMetricsManager. ExoPlayer will forward playback events and performance data to the platform, which helps to provide system performance and debugging information on the device. This data may also be collected by Google if sharing usage and diagnostics data is enabled by the user of the device. Apps can opt-out of contributing to platform diagnostics for ExoPlayer with ExoPlayer.Builder.setUsePlatformDiagnostics(false).
  • Fix bug that tracks are reset too often when using MergingMediaSource, for example when side-loading subtitles and changing the selected subtitle mid-playback (#10248).
  • Stop detecting 5G-NSA network type on API 29 and 30. These playbacks will assume a 4G network.
  • Disallow passing null to MediaSource.Factory.setDrmSessionManagerProvider and MediaSource.Factory.setLoadErrorHandlingPolicy. Instances of DefaultDrmSessionManagerProvider and DefaultLoadErrorHandlingPolicy can be passed explicitly if required.
  • Add MediaItem.RequestMetadata to represent metadata needed to play media when the exact LocalConfiguration is not known. Also remove MediaMetadata.mediaUrl as this is now included in RequestMetadata.
  • Add Player.Command.COMMAND_SET_MEDIA_ITEM to enable players to allow setting a single item.
• Track selection:
  • Flatten TrackSelectionOverrides class into TrackSelectionParameters, and promote TrackSelectionOverride to a top level class.
  • Rename TracksInfo to Tracks and TracksInfo.TrackGroupInfo to Tracks.Group. Player.getCurrentTracksInfo and Player.Listener.onTracksInfoChanged have also been renamed to Player.getCurrentTracks and Player.Listener.onTracksChanged.
  • Change DefaultTrackSelector.buildUponParameters and DefaultTrackSelector.Parameters.buildUpon to return DefaultTrackSelector.Parameters.Builder instead of the deprecated DefaultTrackSelector.ParametersBuilder.
  • Add DefaultTrackSelector.Parameters.constrainAudioChannelCountToDeviceCapabilities which is enabled by default. When enabled, the DefaultTrackSelector will prefer audio tracks whose channel count does not exceed the device output capabilities. On handheld devices, the DefaultTrackSelector will prefer stereo/mono over multichannel audio formats, unless the multichannel format can be Spatialized (Android 12L+) or is a Dolby surround sound format. In addition, on devices that support audio spatialization, the DefaultTrackSelector will monitor for changes in the Spatializer properties and trigger a new track selection upon these. Devices with a television UI mode are excluded from these constraints and the format with the highest channel count will be preferred. To enable this feature, the DefaultTrackSelector instance must be constructed with a Context.
• Video:
  • Rename DummySurface to PlaceholderSurface.
  • Add AV1 support to the MediaCodecVideoRenderer.getCodecMaxInputSize.
• Audio:
  • Use LG AC3 audio decoder advertising non-standard MIME type.
  • Change the return type of AudioAttributes.getAudioAttributesV21() from android.media.AudioAttributes to a new AudioAttributesV21 wrapper class, to prevent slow ART verification on API < 21.
  • Query the platform (API 29+) or assume the audio encoding channel count for audio passthrough when the format audio channel count is unset, which occurs with HLS chunkless preparation (10204).
  • Configure AudioTrack with channel mask AudioFormat.CHANNEL_OUT_7POINT1POINT4 if the decoder outputs 12 channel PCM audio (#10322.
• DRM
  • Ensure the DRM session is always correctly updated when seeking immediately after a format change (10274).
• Text:
  • Change Player.getCurrentCues() to return CueGroup instead of List<Cue>.
  • SSA: Support OutlineColour style setting when BorderStyle == 3 (i.e. OutlineColour sets the background of the cue) (#8435).
  • CEA-708: Parse data into multiple service blocks and ignore blocks not associated with the currently selected service number.
  • Remove RawCcExtractor, which was only used to handle a Google-internal subtitle format.
• Extractors:
  • Matroska: Parse DiscardPadding for Opus tracks.
  • MP4: Parse bitrates from esds boxes.
  • Ogg: Allow duplicate Opus ID and comment headers (#10038).
• UI:
  • Fix delivery of events to OnClickListeners set on StyledPlayerView and PlayerView, in the case that useController=false (#9605). Also fix delivery of events to OnLongClickListener for all view configurations.
  • Fix incorrectly treating a sequence of touch events that exit the bounds of StyledPlayerView and PlayerView before ACTION_UP as a click (#9861).
  • Fix PlayerView accessibility issue where tapping might toggle playback rather than hiding the controls (#8627).
  • Rewrite TrackSelectionView and TrackSelectionDialogBuilder to work with the Player interface rather than ExoPlayer. This allows the views to be used with other Player implementations, and removes the dependency from the UI module to the ExoPlayer module. This is a breaking change.
  • Don't show forced text tracks in the PlayerView track selector, and keep a suitable forced text track selected if "None" is selected (#9432).
• DASH:
  • Parse channel count from DTS AudioChannelConfiguration elements. This re-enables audio passthrough for DTS streams (#10159).
  • Disallow passing null to DashMediaSource.Factory.setCompositeSequenceableLoaderFactory. Instances of DefaultCompositeSequenceableLoaderFactory can be passed explicitly if required.
• HLS:
  • Fallback to chunkful preparation if the playlist CODECS attribute does not contain the audio codec (#10065).
  • Disallow passing null to HlsMediaSource.Factory.setCompositeSequenceableLoaderFactory, HlsMediaSource.Factory.setPlaylistParserFactory, and HlsMediaSource.Factory.setPlaylistTrackerFactory. Instances of DefaultCompositeSequenceableLoaderFactory, DefaultHlsPlaylistParserFactory, or a reference to DefaultHlsPlaylistTracker.FACTORY can be passed explicitly if required.
• Smooth Streaming:
  • Disallow passing null to SsMediaSource.Factory.setCompositeSequenceableLoaderFactory. Instances of DefaultCompositeSequenceableLoaderFactory can be passed explicitly if required.
• RTSP:
  • Add RTP reader for MPEG4 (#35).
