Media3: v1.9.0-alpha01

October 22, 2025

androidx.media3:media3-*:1.9.0-alpha01 is released. Version 1.9.0-alpha01 contains these commits.

• Common Library:
  • Update minSdk to 23 in line with other AndroidX libraries.
  • Add PlayerTransferState, which facilitates transferring the playback state across Player instances.
  • Add void mute() and void unmute() methods to Player that preserve and consequently restore Player's volume before and after setting it to zero.
  • Publish utility classes WakeLockManager, WifiLockManager, AudioFocusManager, AudioBecomingNoisyManager and StuckPlayerDetector previously used by ExoPlayer internally to allow reuse for other players (#1893).
  • Fix ForwardingPlayer listener handling when the underlying delegate player uses reference equality for comparing listener instances (#2675).
  • Add a Player.listenTo suspending extension function in the media3-common-ktx library that specifies the particular Player.Events that should be acted upon.
  • Fix a crash in BasePlayer.getBufferedPercentage resulting from integer overflow when the reported buffered position is implausibly much larger than the reported duration (#2750).
• ExoPlayer:
  • Add a stuck player detection that triggers a StuckPlayerException player error if the player seems stuck. This happens in the following cases, where each default timeout can be configured in ExoPlayer.Builder if required:
    • After 10 minutes of STATE_BUFFERING while trying to play and no buffering progress.
    • After 10 seconds of STATE_READY while trying to play and no playback progress.
    • After 1 minute of STATE_READY beyond the declared duration without reaching the end of the item.
    • After 10 minutes with a playback suppression reason while trying to play.
  • Enable wake lock handling by default to fix issues with buffering during background playback. This is equivalent to setting ExoPlayer.Builder.setWakeMode to C.WAKE_MODE_LOCAL.
  • Add listening logic to automatically update the virtual device ID when a change is reported to the Context originally passed to ExoPlayer.Builder.
  • Add ExoPlayer.setVirtualDeviceId to manually update the virtual device ID obtained from the Context passed to ExoPlayer.Builder.
  • Ensure renderers don't consume data from the next playlist item more than 10 seconds before the end of the current item.
  • Add setSeekBackIncrementMs, setSeekForwardIncrementMs and setMaxSeekToPreviousPositionMs to ExoPlayer to update these settings after construction (#2736).
  • Add pre-caching functionality in DefaultPreloadManager. Apps now can return DefaultPreloadManager.PreloadStatus.specifiedRangeCached(startPositionMs, durationMs) or DefaultPreloadManager.PreloadStatus.specifiedRangeCached(durationMs) via TargetPreloadStatusControl.getTargetPreloadStatus(T rankingData) to indicate that a media item needs to be pre-cached.
  • Use pre-caching functionality of DefaultPreloadManager in shortform demo app.
  • Add DefaultLoadControl.Builder setters for local playback and adjust default values of DefaultLoadControl to work well with a wide range of local files.
  • Fix bug where setting an empty playlist can leave the player in STATE_READY or STATE_BUFFERING.
  • Enhance the preload manager APIs:
    • Add addMediaItems(List<MediaItem>, List<T>) and addMediaSources(List<MediaSource>, List<T>) that add the media items or media sources in batch, and automatically call invalidate() afterwards.
    • Add removeMediaItems((List<MediaItem>) and removeMediaSources(List<MediaSource>) that remove the media items or media sources in batch, and make sure that preload manager does not start to preload or continue preloading any of them after removal.
    • Allow DefaultPreloadManager.setCurrentPlayingIndex(int) to invalidate itself automatically. Apps don't need to call invalidate() explicitly anymore after updating the current playing index.
  • Add capability to skip keyframe reset for forward seeks within the same group of pictures while in scrubbing mode.
  • Add DefaultLoadControl.Builder.setPlayerTargetBufferBytes(String, int) for apps to set a value of target buffer bytes for a player with the specified playerName. The DefaultLoadControl can now make decisions of each player separately based on its own allocated bytes and target buffer bytes.
  • Add SkipInfo to the AdPlaybackState.AdGroup to carry skip information for each ad in the ad group.
  • Fix bug where calling removeMediaItems(List) during playing a post-roll created a crash (#2746).
  • Fix some stuttering in playlist playback where frames were mistakenly always set as the last sample and rendered.
  • Enable retry path if player fails to generate audio session ID (#2382, #2678).
  • Add support to control the total buffer bytes for the sources in DefaultPreloadManager to avoid total buffer bytes for preloading from growing arbitrarily. To use the default control logic, Apps can set the target buffer bytes for preloading via DefaultLoadControl.Builder.setPlayerTargetBufferBytes(String, int) for a playerName of PlayerId.Preload.name ("preload"), and inject the created DefaultLoadControl via DefaultPreloadManager.Builder.setLoadControl(LoadControl).
• CompositionPlayer:
  • Publish CompositionPlayer under a new @ExperimentalApi annotation to indicate it is available for experimentation, but is still under development. Some APIs are likely to change significantly in future releases, and there are known issues and limitations with some use-cases (some undocumented).
  • Add support for COMMAND_SET_AUDIO_ATTRIBUTES and audio focus handling in CompositionPlayer.
  • Add support for speed changing in secondary sequences in CompositionPlayer.
• Transformer:
  • Use InAppMp4Muxer as default muxer.
  • Add EditedMediaItem.Builder#setSpeed() and deprecate Effects#createExperimentalSpeedChangingEffects().
  • Replace forceAudioTrack and forceVideoTrack with trackTypes in EditedMediaItemSequence.
• Track Selection:
  • Add TrackSelectionParameters.selectTextByDefault to prefer the selection of any text track without specifying other more specific preferences.
  • Add preferredVideoLabels, preferredAudioLabels and preferredTextLabels in TrackSelectionParameters to specify a preference for tracks with a specific label, for example those read from HLS NAME tags (#1666).
• Extractors:
  • FLAC: Tighten header detection to reduce the chance of finding spurious headers in the encoded FLAC data, resulting in decoding errors (#558).
  • MP3: Allow gaps between (and before) ID3 tags at the beginning of MP3 files (#811, #5718).
  • MP4: Disambiguate between audio/mpeg (MP3), audio/mpeg-L1 and audio/mpeg-L2 MIME types by peeking the layer value of the first sample before emitting a track format from the extractor (#2683).
  • MP4: Improve sniffing efficiency of very large files by assuming a stbl box larger than 1MB implies the file must be non-fragmented (#2650).
  • Matroska: Add support for DTS-HD detection (#6225).
  • Fix an issue in MatroskaExtractor where seeking could be inaccurate for files with multiple tracks. Cue points are now correctly associated with their respective tracks, leading to more precise seeking.
  • MP4: Add support for ©mvn (movement name) and ©mvi (movement index) metadata, these are now emitted as TextInformationFrame objects in Format.metadata with IDs of MVNM and MVIN respectively (#2754).
  • MPEG-TS: Fix IllegalArgumentException from ReorderingBufferQueue caused by PES packets with no timestamp (#2764).
  • MP4: Ignore tracks with missing stsd box (instead of failing to parse the whole file).
  • Add support for extracting HEIC Motion Photos. The HeifExtractor can now parse HEIC files containing embedded video and audio tracks.
  • MP3: Change FLAG_ENABLE_INDEX_SEEKING to prefer seeking information from metadata headers (like Xing and VBRI) when available, falling back to index-based seeking if no other seeking information is present. This improves performance for files with seeking metadata (#2839).
• Inspector:
  • Introduced a new :media3-inspector module to serve as the dedicated home for media inspection utilities. This module now houses a new androidx.media3.inspector.MetadataRetriever, which will provide a unified API for both metadata and frame extraction. The existing androidx.media3.exoplayer.MetadataRetriever is now deprecated in favor of this new version.
  • Introduced androidx.media3.inspector.FrameExtractor, a new public API for frame extraction. This AutoCloseable class provides a way to extract frames with support for HDR video, video effects, and custom decoder selection. It should be created via its Builder for a specific MediaItem.
  • FrameExtractor: Add getThumbnail() to extract a representative thumbnail frame from a media file without requiring a specific timestamp.
• Audio:
  • Make AudioProcessor instances aware of seeking.
  • Allow injecting the new AudioOutputProvider interface into DefaultAudioSink.Builder to support custom audio output paths. The default is AudioTrackAudioOutputProvider.
  • Handle seeks in GainProcessor.
  • Utilize AC-4 decoder profile and level capabilities in track format support assessment (#2580).
  • Avoid potential delays caused by handling routing change callbacks at the beginning of playback (#2646).
  • Allow codec reuse for EAC3, EAC3-JOC and AC-4 formats (#1346).
  • Add support for float PCM samples in Sonic.
  • Add support for 16 bit PCM samples in ToFloatPcmAudioProcessor.
• Video:
  • Disable codec reuse for Dolby-Vision content with different profiles.
• Text:
  • Fix parsing of CEA-6/708 subtitles in Dolby Vision content (#2775).
• Image:
  • Fix ScrubbingMode issue where player gets stuck while scrubbing a DASH thumbnail track (#2815).
• DRM:
  • Change the return type of MediaDrmCallback methods from byte[] to a new MediaDrmCallback.Response type, to allow returning extra optional information. This is a source breaking change, but breakages can be easily resolved by wrapping the previous byte[] return value with new Response before returning.
  • Add key request info like URL and latency to AnalyticsListener.onDrmKeysLoaded (#1001).
  • Move provisioning request data from a URL parameter to the POST body.
• Muxers:
  • Add MediaMuxerCompat, a drop-in replacement for framework MediaMuxer.
  • Add MuxerUtil.createMotionPhotoFromJpegImageAndBmffVideo() to allow Motion Photo creation.
  • Add WebmMuxer to allow muxing of OPUS, VORBIS, VP8 and VP9 media streams into a webm file format.
• IMA extension:
  • Removal of custom proguard rules, so that apps can use those released in IMA android archive instead.
  • Add ImaServerSideAdInsertionUriBuilder.setNetworkCode, a new API for setting the Google Ad Manager network code for the IMA SDK to handle ads identifiers as specified in Google Ad Manager settings. Network codes are optional but recommended for Full service stream requests. To find the network code, see this article.
  • Bump IMA dependency to 3.37.0 which requires enabling core library desugaring. This must also be enabled by dependent apps too. See IMA's config notes.
  • Support IMA DAI custom UI options in SSAI URI builder. Custom UI options for server side ad insertion include "Skippable" and "About This Ad" rendering support. The feature is currently available for selected publishers behind an allow list. This change also upgrades the IMA SDK version to 3.38.0 (release notes) to access the custom UI options API.
• Session:
  • Add new parameter to MediaSession.Callback.onPlaybackResumption to indicate if the call happens to gather information only or to start playback (#1764).
  • Update MediaSession.ControllerInfo.isTrusted to also declare controllers from the own app as trusted (#2542).
  • Add MediaSessionService.triggerNotificationUpdate to manually trigger a notification update (#1833).
  • Add ProgressListener to custom command methods.
  • Change the default value for MediaLibrarySession.Builder.setLibraryErrorReplicationMode to non fatal.
  • Add a Context parameter to MediaButtonReceiver.onForegroundServiceStartNotAllowedException (#2625).
  • Read the volume control ID from the platform PlaybackInfo instead of fetching it via binder. This ensures that playback type and volume control ID are read atomically and do match to each other.
  • Fix bug where ACTION_UP key events were filtered out before passing them to the callback for custom handling. This brings parity with what media1 did and the platform does (#2637).
  • Fix bug where getCurrentTimeline() was called by PlayerWrapper even when the command isn't available (#2665).
  • Fix bug where a message was left in the message queue of the main looper which caused a memory leak after the service terminated (#2692).
  • When connected to a legacy session app with a MediaBrowser, custom commands are sent to the session only if the custom action is advertised as a custom action in PlaybackStateCompat of the legacy session. All other custom actions are sent to the service.
  • Implemented onAudioSessionIdChanged to notify media controllers when an audio session ID is set by the session (#244).
  • Fix bug where KEYCODE_HEADSETHOOK did not start the player upon and media key event Intent arriving in onStartCommand(). This is fixed by handling 'KEYCODE_HEADSETHOOK' just like KEYCODE_MEDIA_PLAY_PAUSE (#2816).
  • Fix a bug where Surface size was not communicated between the session and the controller, resulting in the failure to apply video effects in demo-session. If you are using a controller, this might be a breaking change if your player cannot handle a setVideoSurfaceHolder call.
  • Fix propagation of non-String CharSequence metadata values like span-styled strings (#2853).
• UI:
  • Add ProgressStateWithTickInterval class and the corresponding rememberProgressStateWithTickInterval Composable to media3-ui-compose module. This state holder is used in demo-compose to display the current position and duration in text form.
  • Add MuteButtonState to ui-compose that handles muting of the Player volume. This state holder is used in demo-compose to display mute/unmute toggle button.
  • Add ProgressStateWithTickCount classes and the corresponding rememberProgressStateWithTickCount Composable to media3-ui-compose module. This state holder is used in demo-compose to display progress as a horizontal read-only progress bar.
  • Add ContentFrame Composable to media3-ui-compose which combines PlayerSurface management with aspect ratio resizing and covering with a shutter.
  • Work around a known API 34 platform bug causing stretched/cropped videos when using SurfaceView inside a Compose AndroidView and hence affecting ContentFrame and PlayerSurface Composables with SURFACE_TYPE_SURFACE_VIEW (#1237, #2811).
  • Create a new media3-ui-compose-material3 module and add Material3-themed Composables (PlayPauseButton, NextButton, PreviousButton, SeekBackButton, SeekForwardButton, RepeatButton, ShuffleButton, MuteButton) to it.
  • Add support for placing a media route button in the PlayerView.
• HLS extension:
  • Parse HLS interstitial skip attributes.
  • Map skip control attributes from the HLS playlist and the asset list document into the AdPlaybackState for public access.
  • Fix bug where the start time of the playlist was dropped when the EXT-X-PROGRAM-START-DATE tag defining the start time was removed from a playlist (#2760).
  • Use binary search to find the segment index of a given position in the playlist (#2826.
• DASH extension:
  • Fix UnsupportedOperationException when playing DASH streams with a non-hierarchical data: URI manifest (#2688).
  • Reset LiveConfiguration to the value provided by the MediaItem of the DashMediaSource when released and when the media item is updated by the user (#2606).
  • Avoid crashes caused by invalid manifest updates that were not reported as player errors (#2805).
• RTSP extension:
  • Handle error of missing RTP packets when processing fragmented NAL units for H264 and H265 (#2613).
• Decoder extensions (FFmpeg, VP9, AV1, etc.):
  • AV1 Extension: The AV1 software decoder now uses the high-performance dav1d library, replacing the previous libgav1 implementation for improved decoding speed.
• Cast extension:
  • Add CastPlayer.Builder, which enables CastPlayer to do both local and Cast playback. To keep the old CastPlayer behavior of supporting only Cast playback, you can use RemoteCastPlayer. The pre-existing CastPlayer constructors keep their old behavior, but are deprecated in favour of using the CastPlayer or RemoteCastPlayer builders instead.
  • Stop enforcing a non-null mime type in DefaultMediaItemConverter.
  • Use MediaItem.mediaMetadata.mediaType to infer the Cast MEDIA_TYPE to use in DefaultCastOptionsProvider#toMediaQueueItem, when available.
