v1.11.0

Compare Source

This release includes the following changes since the
1.10.1 release:

• Common library:
  • Add Format.channelMask to explicitly represent the audio channel mask,
    and a new Util.getAudioTrackChannelConfig(Format) overload to safely
    resolve it.
  • Upgrade Kotlin from 2.0.20 to 2.2.0.
• ExoPlayer:
  • Fix a timing-dependent concurrency bug that could cause an
    IllegalStateException or IndexOutOfBoundsException in ExoPlayer.
  • Relax ad group count checks in AdsMediaSource to allow the ad group
    count to decrease when an ad group is fully processed
    (hasUnplayedAds() is false), accommodating dynamic ad group resizing
    during reset workflows.
  • Add getFlags() and FLAG_STRICT_DURATION to SampleStream to allow
    streams to report flags, and update renderers to check these flags
    dynamically.
  • Fall back to the frame rate estimator in MediaCodecVideoRenderer and
    to the codec output format in MediaCodecAudioRenderer to calculate the
    codec operating rate when the stream formats do not provide a valid
    value, and avoid unnecessary codec resets.
  • Remove clipping of content for client-side inserted ads in the core
    player. Instead, AdsMediaSource takes care of the clipping logic.
    Custom client-side inserted ads sources need to be updated to implement
    the content clipping internally.
  • Mark tracks with a well-formed but unrecognized codec profile or level
    as supported=NO_EXCEEDS_CAPABILITIES instead of supported=YES (which
    is how tracks with missing or malformed profile or level info are
    marked). This ensures these tracks (which are unlikely to be supported
    by the device) are not selected when there are better-supported
    alternatives.
  • Add DefaultPreloadManager.SimpleRankingDataComparator, which is a
    RankingDataComparator that compares the ranks of the media items based
    on their distances to the index of the current playing media item. Apps
    can override its compare(Integer, Integer) method if a more fine-tuned
    comparison logic is needed. The custom SimpleRankingDataComparator can
    be injected via a new constructor of DefaultPreloadManager.Builder.
  • Reduce the OOM risk of
    DefaultLoadControl.prioritizeTimeOverSizeThresholds by falling back to
    buffer byte size limits if available heap memory seems tight.
  • Align handling of still images when MediaItem.imageDurationUs is not
    set: JPEG and HEIC still images now 'play' with a very short default
    duration (the same way PNG and other images previously behaved).
  • Add MediaSource.prepareSource(MediaSourceCaller, PlayerId, BandwidthMeter) to plumb BandwidthMeter to MediaSource. The
    deprecated method with custom implementation will still be called by
    default though, it is recommended to implement the new method and use
    BandwidthMeter.getTransferListener() to get parity to the old method.
  • In DefaultBandwidthMeter, add support for a custom
    InitialBitrateSupplier. This allows apps to provide their own logic
    for determining the initial bitrate estimate, which will be used on
    creation of DefaultBandwidthMeter and on network type changes. The
    supplier can be set via
    DefaultBandwidthMeter.Builder.setInitialBitrateSupplier().
  • Enable dynamic scheduling by default. ExoPlayer playback work loop
    will run dynamically as opposed to on a static interval.
  • Remove an unnecessary reset that can occur when joining tracks with
    pre-roll samples to active playback.
  • In DefaultBandwidthMeter, optimize
    getInitialBitrateCountryGroupAssignment to return the country group
    assignments packed into a 32-bit integer instead of an array, reducing
    code size and avoiding allocations.
  • Fix AudioTrack initialization failures on some devices by ensuring the
    retry logic always attempts a minimum of 1 second buffer size if other
    retries (by halving the buffer size) are unsuccessful
    (#​3207).
  • Fix codec issue on some devices where the codec was swallowing all
    samples if previously flushed before receiving input buffers.
  • Add experimental ExoPlayer.Builder.enablePerStreamMediaProgression()
    to allow advancing media processing on a per-stream basis. This reduces
    startup latency between playlist items and avoids playback becoming
    "stuck" with very short content
    (#​3122).
  • Fix race condition related to audio session id usage where the initial
    audio session id auto-generated by ExoPlayer would be used instead of
    the value set by setAudioSessionId
    (#​3241).
  • Add experimental HAGC (ST 2094-50) timed metadata playback support for
    progressive media (e.g. MP4, Matroska). The player automatically merges
    HAGC metadata tracks with the associated video track and delivers the
    metadata out-of-band to the decoder on API 37+ devices. This behavior
    can be disabled via
    DefaultMediaSourceFactory.setExperimentalEnableHagcPlayback(false).
  • Add Format.selectionPriority representing the relative preference of
    the Format in track selection
    (#​3236).
  • Fix potential scrubbing mode issue where scrubbing could stall when
    seeking to 'end of stream'.
• CompositionPlayer:
  • Fix an issue where TrackSelector instances were not being released.
• Transformer:
  • Fix an issue where ExportResult.fileSizeBytes may be over-reported.
• Track selection:
  • Expose BaseTrackSelection.DEFAULT_FORMAT_COMPARATOR and add
    AdaptiveTrackSelection.Factory.setTrackFormatComparator to allow
    custom format ordering and ABR selection priority beyond bitrate-only
    ordering.
  • Fix a timing-dependent concurrency issue where rapid sequential updates
    to track selection parameters could result in some updates being lost or
    overwritten.
• Extractors:
  • MP4, MP3, and FLAC: Add FLAG_DISABLE_ARTWORK_METADATA to allow
    discarding attached pictures and cover art metadata during container
    parsing to reduce runtime memory consumption
    (#​2077). This can also
    be enabled centrally via
    DefaultExtractorsFactory.setDisableArtworkMetadata.
  • MP4: Add support for extracting ITU-T T.35 (it35) timed metadata
    tracks.
  • MP4: Add support for extracting chapter metadata (both Nero and
    QuickTime formats). QuickTime chapters are preferred if both are
    present. The extracted chapter information is exposed as Chapter
    entries within the track's Metadata, allowing for native chapter
    navigation in MP4, M4A, and M4B files (such as audiobooks and podcasts)
    (#​2803).
  • WAV, Matroska, and MP4: Add support for 64-bit floating point PCM audio
    (#​3090).
  • Matroska: Use codec bitstream metadata to populate accurate ColorInfo.
  • MP4: Add support for seeking in fragmented MP4 files using the mfra
    box when a sidx box is not present. To enable this, provide
    FLAG_READ_MFRA_FOR_SEEK_MAP to the FragmentedMp4Extractor, which is
    now done by default in DefaultExtractorsFactory
    (#​3088).
  • Ignore av1C data with unsupported version.
  • MP4: Add support for big-endian floating point PCM in fpcm boxes.
  • Matroska: Parse chapter info to Chapter entries in a track's
    Metadata.
  • MPEG-TS: Improve extraction of DTS-HD and DTS Express streams by
    combining the Core and Extension Substream into a single sample, fixing
    playback issues where the two were previously output as separate samples
    (#​3147).
  • MP4: Prevent infinite loops and out-of-bounds reads when parsing empty
    ilst metadata tag items
    (#​3191).
  • MPEG-TS: Ensure the last frame is rendered for streams where the last
    PES packet has a known length
    (#​3206).
  • MP3: Fix bitrate reporting for files with Xing and VBRI header.
  • Matroska: Handle tracks defined in the last cluster
    (#​3250).
  • Matroska: Add support for ALAC
    (#​3268).
  • MP4: Allow variable length sgpd boxes in fragmented MP4 files
    (#​3243).
  • AVI: Fix an issue where playing files without keyframe flags on audio
    tracks caused audio loss and OutOfMemoryError.
  • MP3: Use gapless-aware durations from Xing/Info headers
    (#​3183).
  • MP3: Adjust LAME/Xing encoder delay and padding metadata to match
    decoded PCM trimming
    (#​3200).
• Audio:
  • Add a 100ms grace period in ExoPlayer's audio renderers when
    transitioning from ready to not-ready state, to debounce transient
    underruns and avoid unexpected buffering states during active playout
    (#​3210).
  • Change the default PCM buffer size logic in
    DefaultAudioTrackBufferSizeProvider to use a fixed 500ms buffer to
    make it less device dependent.
  • Update MediaCodecAudioRenderer to extract the spatial channelMask from
    the platform decoder, allowing DefaultAudioSink to use this explicit
    mask instead of inferring one from the channel count.
  • Convert parameters of AudioSink.configure to data class. Custom
    overrides of ForwardingAudioSink.configure need to be migrated to the
    new method signature.
  • Add support for maintaining pitch when time-stretching an audio stream
    with EditedMediaItem.Builder#setSpeed(SpeedParameters).
  • Enhance ToFloatPcmAudioProcessor to support converting 8-bit PCM,
    16-bit big-endian PCM, and 64-bit floating point PCM to 32-bit floating
    point PCM (#​3090).
  • Change return value of DecoderAudioRenderer.getChannelMapping to
    ImmutableIntArray.
  • Fix bug where playback gets stuck when playing a playlist of gapless
    audio in compressed offload mode.
  • Forward Timeline and period UID to AudioSink.configure and
    AudioProcessor.StreamMetadata to provide playlist context to the audio
    processors (#​418).
  • Set correct AudioProcessor.StreamMetadata.positionOffsetUs to allow
    time-based audio processing
    (#​418).
  • Add support for big endian 32-bit and 64-bit floating point PCM.
  • Remove fallback path of EAC3-JOC to EAC3 for playback on Google Pixel
    devices as their standard EAC3 decoders cannot decode EAC3-JOC streams
    (#​3257).
• Video:
  • Fix video joining logic to count dropped buffers during joining as
    skipped instead of dropped.
  • Fix immediate rendering decision when setting new surface to avoid frame
    drops on devices that don't support placeholder surfaces.
  • Fix frame rate estimation in MediaCodecVideoRenderer to be more
    accurate by accounting for dropped or skipped frames.
  • Allow configuration of the threshold used to schedule frames early. The
    default is 50ms but one can customize the value through
    MediaCodecVideoRenderer.Builder.setMaxEarlyUsThreshold().
  • Fix bug in VideoFrameReleaseHelper where display changes could trigger
    redundant Choreographer callbacks and excessive CPU wakeups on the
    main thread.
• Text:
  • TTML: Fallback to displayAlign from style for regions
    (#​2559).
  • TTML: Inherit cue start time from parent of <p> elements
    (#​3246).
• Metadata:
  • Add MediaMetadata.discSubtitle field and parse it from ID3v2.4 TSST
    and Vorbis DISCSUBTITLE data.
  • Parse disc number & count from ID3 TPOS frame.
• Effect:
  • Clear redraw state in FinalShaderProgramWrapper when flushing to
    prevent the player from freezing when seeking.
• Muxers:
  • Add support for track references (the tref box) in Mp4Muxer via a
    new addTrackReference API. This allows establishing relationships
    between tracks, such as linking a metadata track to the video track it
    describes.
  • Add OggMuxer to allow muxing of OPUS or VORBIS media streams into
    the ogg file format.
  • Add WavMuxer for WAV file generation (supports integer and
    floating-point PCM).
  • Add setAttemptStreamableOutputEnabled to InAppMp4Muxer.Factory to
    allow writing smaller non-streamable files without reserved space.
  • Add support for IAMF audio in Mp4Muxer and FragmentedMp4Muxer.
• IMA extension:
  • Add
    ImaServerSideAdInsertionMediaSource.AdsLoader.Builder.setPauseAdSlot
    to allow providing an ad slot to use for pause ads.
  • Fix bug where back-to-back skippable VAST ads show the skip button
    immediately on the second ad
    (#​3165).
• Session:
  • Fix potential deadlocks and IllegalStateException crashes inside
    MediaNotificationManager when using a session with a background thread
    player looper.
  • Enforce stricter threading requirements for MediaSession methods. Void
    methods now automatically post execution to the application looper
    thread, and state accessors (getters) explicitly throw an
    IllegalStateException if called from a thread other than the
    application looper.
  • Fix an out-of-bounds timeline merge crash (IllegalStateException in
    MediaUtils.mergePlayerInfo) by tracking state consistency
    per-controller on the session side.
  • Add androidx.media3.session.MediaSessionManager to provide support for
    querying active media sessions and returning Media3 SessionToken
    instances.
  • Change default behavior of MediaSession.Callback.onConnect if the
    method is not overridden to only provide read access to untrusted
    controllers.
  • Add support to override package name while creating MediaSession via a
    new API MediaSession.Builder#setPackageNameOverride. The caller must
    have android.permission.OVERRIDE_MEDIA_SESSION_OWNER permission to
    override the package name of the session.
  • Add MediaSession.Callback.onConnectAsync(). The new method allows to
    asynchronously process the connection attempt of a controller. Apps can
    return an immediate Future with
    Futures.immediateFuture(ConnectionResult) to achieve the previous
    behaviour. It's recommended to migrate to the new method because
    Callback.onConnect is a candidate to be deprecated.
  • Fix issue where Bluetooth AVRCP browsing didn't recognise
    MediaLibraryService on API 36 and 37.
  • Fix double-downscaling of artwork in MediaSession when the image size
    is close to the platform limit, resolving blurriness in notifications
    (#​3134).
  • Fix ForegroundServiceStartNotAllowedException crash in
    MediaNotificationManager when an asynchronous artwork bitmap load
    callback attempts to start the foreground service while the app is in
    the background (#​3270).
  • Fix an issue where PositionInfo objects received by a
    MediaController were missing their original Timeline UIDs. The
    session now reliably translates and propagates these UIDs during state
    updates.
  • Fix crash by catching ForegroundServiceStartNotAllowedException in
    MediaSessionService.stopSelfSafely()
    (#​3310).
  • Fix unexpected onMediaItemTransition() callback on MediaController
    when seeking inside the same media item
    (#​3248).
• UI:
  • Fix first frame rendering at the wrong size when ContentFrame is
    recomposed mid-playback
    (#​3238).
  • Add CurrentMediaItemState class and the corresponding
    rememberCurrentMediaItemState Composable to media3-ui-compose
    module. This state holder is used in demo-compose to display various
    metadata information about the currently playing MediaItem.
  • Add PlaylistState class and the corresponding rememberPlaylistState
    Composable to media3-ui-compose module. This state holder is used in
    demo-compose to display various metadata information about the
    MediaItems set on the Player.
  • Add fastforwarding/slow motion API to PlaybackSpeedState. Use this
    functionality in demo-compose to showcase fastforwarding with a long
    press.
  • Add MiniController composable to media3-ui-compose-material3 module.
    It provides a compact affordance to control the Player while
    displaying the title, artist, artwork, and progress of the current media
    item.
  • Add ErrorState class and the corresponding rememberErrorState
    Composable to media3-ui-compose module. Add ErrorText Composable to
    media3-ui-compose-material3 and make it a default overlay on the
    Player.
  • Publish PlayerDefaults object with composables for TopControls,
    CenterControls, BottomControls, and ErrorOverlay.
  • Add FocusRequester to Player Composable and its content slots.
  • Publish PlayerPool (common-ktx) and rememberPooledPlayer
    (ui-compose) to support preloading of MediaItems in sliding window
    UI environments. Showcase this functionality in demo-compose with a
    new ShortFormPlayerScreen.
  • Fix shutter suppression bug in PlayerView and Compose
    PresentationState that caused crashes on timelines that do not support
    period UID lookup
    (#​3264).
• Downloads:
  • Resolve HLS variables in media playlist when fetched for download
    (#​3258).
• Ktor extension:
  • Add a new media3-datasource-ktor extension module providing a
    KtorDataSource backed by the Ktor HTTP stack.
  • Fix KtorDataSource loading the entire HTTP response body into memory
    when opening a connection
    (#​3305).
• HLS extension:
  • Add support for HLS Content Steering and Pathway Cloning
    (#​1689).
  • Add setWithAssetListReset to HlsInterstitialsAdsLoader to allow apps
    to reset fully processed asset list interstitials back to an unavailable
    state for on-demand re-resolution.
  • Parse SCORE attribute of EXT-X-STREAM-INF and
    EXT-X-I-FRAME-STREAM-INF, and populate it to
    Format.selectionPriority
    (#​3236).
  • Fix bug where scheduled HLS playlist refreshes continue even if the
    playlist is no longer primary or active
    (#​3254).
  • Fix calculation of content resume offset when resolving interstitial
    asset lists (#​3322).
  • Fix unexpected audio track timestamp discontinuity when resuming low
    latency live playback after a playlist request failure
    (#​3311).
  • Fix bug in HlsMediaPeriod.getStreamKeys() where the ID3 track in audio
    renditions is considered as subtitles
    (#​3333).
• DASH extension:
  • Separate CEA closed captions into different TrackGroups based on
    language (#​3113).
  • Add support for parsing multiple Location elements from the manifest
    (MPD) and performing location fallback in DashMediaSource when
    manifest loads fail.
  • Fix crash (IndexOutOfBoundsException) when opening manifests with an
    empty <SegmentTimeline/> element
    (#​3326).
• RTSP extension:
  • Fix transient playback stalls or failures during RTSP playback
    preparation caused by UDP port binding errors.
• Cast extension:
  • Add new CastParams class to allow configuration of Cast by calling
    Cast.initialize(CastParams).
  • Add new CastParams.getShowSystemOutputSwitcherOnCastIconClick()
    option, which triggers the use of the SystemUI Output Switcher instead
    of the in-app Cast device picker when available.
  • Add MediaRouteButtonState and rememberMediaRouteButtonState to
    support observing the visibility state of the media route picker, and
    add state parameter to MediaRouteButton
    (#​3172).
  • Fix bug where RemoteCastPlayer could get permanently stuck in a
    track-masking state after a track selection, causing it to ignore
    subsequent track updates from the Cast receiver
    (#​3237).
  • Fix bug where DefaultMediaItemConverter throws a
    NullPointerException when trying to join a cast session started from a
    non-Media3 sender.
  • Prevent CastPlayer from transferring MediaItems that are not
    playable when changing the active player
    (#​3199).
  • Fix bug where unconfigured live streams (liveConfiguration == UNSET)
    were queued as STREAM_TYPE_BUFFERED
    (#​3318).
• Test utilities:
  • Expand DataSourceContractTest to include support for POST requests
    with headers & bodies, add some POST resources to
    HttpDataSourceTestEnv, and add assertions for the expected HTTP
    method, headers & body in WebServerDispatcher.
  • Tighten assertions in DataSourceContractTest for lengths returned from
    DataSource.open(). Resources that may result in C.LENGTH_UNSET
    should indicate this by using
    TestResource.Builder.setMayResolveToUnknownLength(boolean).
  • Add setPlaybackLooper to TestExoPlayerBuilder.
• Remove deprecated symbols:
  • Remove androidx.media3.exoplayer.MetadataRetriever. Use
    androidx.media3.inspector.MetadataRetriever instead.
  • Remove androidx.media3.exoplayer.MediaExtractorCompat. Use
    androidx.media3.inspector.MediaExtractorCompat instead.
  • Remove Mp4Extractor.FLAG_READ_MOTION_PHOTO_METADATA. Use
    HeifExtractor to extract motion photo metadata from HEIC files
    instead.
  • Remove androidx.media3.extractor.metadata.mp4.MotionPhotoMetadata. Use
    androidx.media3.extractor.metadata.MotionPhotoMetadata instead.
  • Remove androidx.media3.extractor.DummyTrackOutput. Use
    androidx.media3.extractor.DiscardingTrackOutput instead.
  • Remove androidx.media3.extractor.DummyExtractorOutput. Use
    androidx.media3.extractor.NoOpExtractorOutput instead.
  • Remove androidx.media3.common.C.generateAudioSessionIdV21. Use
    androidx.media3.common.util.Util.generateAudioSessionId instead.
• Build
  • Updated the README.md instructions for depending on Media3 locally to
    use Gradle Composite Builds (includeBuild). The core_settings.gradle
    script has been removed, and the androidxMediaModulePrefix and
    androidxMediaEnableMidiModule properties are no longer used.
