• Common Library:
  • Upgrade androidx.annotation:annotation-experimental to 1.3.1. This also introduces a transitive dependency on the Kotlin standard library from media3-common. Apps can downgrade to remove this dependency if they want. Fixes https://issuetracker.google.com/251172715.
  • Move ExoPlayer.setAudioAttributes to the Player interface.
• ExoPlayer:
  • Add additional fields to Common Media Client Data (CMCD) logging: next object request (nor) and next range request (nrr)(#8699).
  • Add functionality to transmit Common Media Client Data (CMCD) data using query parameters (#553).
  • Fix ConcurrentModificationException in ExperimentalBandwidthMeter (#612).
  • Add MediaPeriodId parameter to CompositeMediaSource.getMediaTimeForChildMediaTime.
  • Support ClippingMediaSource (and other sources with period/window time offsets) in ConcatenatingMediaSource2 (#11226).
  • Change BaseRenderer.onStreamChanged() to also receive a MediaPeriodId argument.
• Transformer:
  • Changed frameRate and durationUs parameters of SampleConsumer.queueInputBitmap to TimestampIterator.
• Extractors:
  • Add BmpExtractor.
  • Add WebpExtractor.
  • Add HeifExtractor.
  • Add QuickTime classic
    support to Mp4Extractor.
• Audio:
  • Add support for Opus gapless metadata during offload playback.
  • Allow renderer recovery by disabling offload if failed at first write (#627).
  • Enable Offload Scheduling by default for audio-only offloaded playback.
  • Delete ExoPlayer.experimentalSetOffloadSchedulingEnabled and AudioOffloadListener.onExperimentalOffloadSchedulingEnabledChanged.
  • Renamed onExperimentalSleepingForOffloadChanged as onSleepingForOffloadChanged and onExperimentalOffloadedPlayback as onOffloadedPlayback.
  • Move audio offload mode related TrackSelectionParameters interfaces
    and definitions to an inner AudioOffloadPreferences class.
• Effect:
  • Changed frameRate and durationUs parameters of VideoFrameProcessor.queueInputBitmap to TimestampIterator.
• IMA extension:
  • Fix bug where a multi-period DASH live stream that is not the first item in a playlist can throw an exception (#571).
  • Release StreamManager before calling AdsLoader.destroy()
  • Bump IMA SDK version to 3.31.0.
• Session:
  • Set the notifications foreground service behavior to FOREGROUND_SERVICE_IMMEDIATE in DefaultMediaNotificationProvider (#167).
  • Use only android.media.session.MediaSession.setMediaButtonBroadcastReceiver() above API 31 to avoid problems with deprecated API on Samsung devices (#167).
  • Use the media notification controller as proxy to set available commands and custom layout used to populate the notification and the platform session.
  • Convert media button events that are received by MediaSessionService.onStartCommand() within Media3 instead of routing them to the platform session and back to Media3. With this, the caller controller is always the media notification controller and apps can easily recognize calls coming from the notification in the same way on all supported API levels.
  • Fix bug where MediaController.getCurrentPosition() is not advancing when connected to a legacy MediaSessionCompat.
  • Add MediaLibrarySession.getSubscribedControllers(mediaId) for convenience.
  • Override MediaLibrarySession.Callback.onSubscribe() to assert the availability of the parent Id for which the controller subscribes. If successful, the subscription is accepted and notifyChildrenChanged() is called immediately to inform the browser (#561).
• RTSP Extension:
  • Fix a race condition that could lead to IndexOutOfBoundsException when falling back to TCP, or playback hanging in some situations.
  • Check state in RTSP setup when returning loading state of RtspMediaPeriod (#577).
  • Ignore custom Rtsp request methods in Options response public header (#613).
• Leanback extension:
  • Fix bug where disabling a surface can cause an ArithmeticException in Leanback code (#617).
