Media3: v1.0.0-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.EventLister. 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).
