1.6.1

• Common Library:
  • Add PlaybackParameters.withPitch(float) method for easily copying a PlaybackParameters with a new pitch value (#2257).
• ExoPlayer:
  • Fix issue where media item transition fails due to recoverable renderer error during initialization of the next media item (#2229).
  • Fix issue where ProgressiveMediaPeriod throws an IllegalStateException as PreloadMediaSource attempts to call its getBufferedDurationUs() before it is prepared (#2315).
  • Fix sending CmcdData in manifest requests for DASH, HLS, and SmoothStreaming (#2253).
  • Ensure AdPlaybackState.withAdDurationsUs(long[][]) can be used after ad groups have been removed. The user still needs to pass in an array of durations for removed ad groups which can be empty or null (#2267).
• Extractors:
  • MP4: Parse alternate_group from the tkhd box and expose it as an Mp4AlternateGroupData entry in each track's Format.metadata (#2242).
• Audio:
  • Fix offload issue where the position might get stuck when playing a playlist of short content (#1920).
• Session:
  • Lower aggregation timeout for platform MediaSession callbacks from 500 to 100 milliseconds and add an experimental setter to allow apps to configure this value.
  • Fix issue where notifications reappear after they have been dismissed by the user (#2302).
  • Fix a bug where the session returned a single-item timeline when the wrapped player is actually empty. This happened when the wrapped player doesn't have COMMAND_GET_TIMELINE available while COMMAND_GET_CURRENT_MEDIA_ITEM is available and the wrapped player is empty (#2320).
  • Fix a bug where calling MediaSessionService.setMediaNotificationProvider is silently ignored after other interactions with the service like setForegroundServiceTimeoutMs (#2305).
• UI:
  • Enable PlayerSurface to work with ExoPlayer.setVideoEffects and CompositionPlayer.
  • Fix bug where PlayerSurface can't be recomposed with a new Player.
• HLS extension:
  • Fix issue where chunk duration wasn't set in CmcdData for HLS media, causing an assertion failure when processing encrypted media segments (#2312).
• RTSP extension:
  • Add support for URI with RTSPT scheme as a way to configure the RTSP session to use TCP (#1484).
• Cast extension:
  • Add support for playlist metadata (#2235).

1.6.0

This release includes the following changes since the 1.5.1 release:

• Common Library:
  • Add AudioManagerCompat and AudioFocusRequestCompat to replace the equivalent classes in androidx.media.
  • Upgrade Kotlin from 1.9.20 to 2.0.20 and use Compose Compiler Gradle plugin. Upgrade KotlinX Coroutines library from 1.8.1 to 1.9.0.
  • Remove Format.toBundle(boolean excludeMetadata) method, use Format.toBundle() instead.
  • Fix bug in SimpleBasePlayer where setting a new currentMediaItemIndex in State after setPlaylist with null MediaMetadata does not reevaluate the metadata (#1940).
  • Change SimpleBasePlayer.State access from protected to public to make it easier to handle updates in other classes(#2128).
• ExoPlayer:
  • Add MediaExtractorCompat, a new class that provides equivalent features to platform MediaExtractor.
  • Add experimental 'ExoPlayer' pre-warming support for playback usingMediaCodecVideoRenderer. You can configure DefaultRenderersFactory through experimentalSetEnableMediaCodecVideoRendererPrewarming to provide a secondary MediaCodecVideoRenderer to ExoPlayer. If enabled, ExoPlayer pre-processes the video of consecutive media items during playback to reduce media item transition latency.
  • Reduce default values for bufferForPlaybackMs and bufferForPlaybackAfterRebufferMs in DefaultLoadControl to 1000 and 2000 ms respectively.
  • Initialize DeviceInfo and device volume asynchronously (if enabled using setDeviceVolumeControlEnabled). These values aren't available instantly after ExoPlayer.Builder.build(), and Player.Listener notifies changes through onDeviceInfoChanged and onDeviceVolumeChanged.
  • Initial audio session id is no longer immediately available after creating the player. You can use AnalyticsListener.onAudioSessionIdChanged to listen to the initial update if required.
  • Consider language when selecting a video track. By default, select a 'main' video track that matches the language of the selected audio track, if available. Explicit video language preferences can be expressed with TrackSelectionParameters.Builder.setPreferredVideoLanguage(s).
  • Add selectedAudioLanguage parameter to DefaultTrackSelector.selectVideoTrack() method.
  • Add retryCount parameter to MediaSourceEventListener.onLoadStarted and corresponding MediaSourceEventListener.EventDispatcher methods.
  • 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).
  • Move BasePreloadManager.Listener to a top-level PreloadManagerListener.
  • RenderersFactory.createSecondaryRenderer can be implemented to provide secondary renderers for pre-warming. Pre-warming enables quicker media item transitions during playback.
  • Enable sending CmcdData for manifest requests in adaptive streaming formats DASH, HLS, and SmoothStreaming (#1951).
