Camera: v1.5.0-alpha06

February 26, 2025

androidx.camera:camera-*:1.5.0-alpha06 is released. Version 1.5.0-alpha06 contains these commits.

API Changes

• Added CameraInfo.getTorchStrengthLevel, CameraInfo.getMaxTorchStrengthLevel and CameraControl.setTorchStrengthLevel to allow customizing the torch brightness (I00878)
• A new API CameraController#setTapToFocusAutoCancelDuration has been added so that users can control the auto-cancellation behavior for PreviewView tap-to-focus events. By default, CameraX cancels the focus events after 5 seconds (i.e. camera focus is reset) and this API allows to modify that duration or disable auto-cancellation altogether. (Icf59a)
• FLASH_STATE_READY has been renamed to NOT_FIRED and the other FlashState constant names are simplified for better readability. (I8771d)
• Exposed Low Light Boost API. Devices running Android 15 or higher can provide support for low-light boost. This feature can automatically adjust the brightness of the preview, video or image analysis streams in low-light conditions. Applications can use the new API to: 1. Use CameraInfo#isLowLightBoostSupported to check the feature availability. 2. Use CameraControl#enableLowLightBoostAsync to enable the mode when the devices can support it. 3. Use CameraInfo#getLowLightBoostState to monitor the low-light boost state. (I937ed)
• Add compat classes to allow faster non-camera2 querying in camera-feature-combination-query. (Ie97ee)
• For CameraController tap-to-focus events, a new API getTapToFocusInfoState() now exposes the corresponding tap position too by returning a LiveData of TapToFocusInfo class while the previous LiveData<Integer> returning getTapToFocusState() API is deprecated in favor of the new API. (I238d2)

Bug Fixes

• Fixed the issue that preview stabilization is not applied when preview stabilization is enabled with Extensions. (I24ad7)
• Fixed CameraController focus state event not resetting back to TAP_TO_FOCUS_NOT_STARTED when CameraX auto-cancels a focus event which happens after 5 seconds by default. (I31954)
• Fixed preview freeze when using Zero Shutter Lag (ZSL) after multiple captures due to unreleased image resources. (Ic3c2a)
• Fixed issues that on some devices UHD videos are red tint when pipeline involves OpenGL. (Idcedc)

Media3: 1.6.0-beta01

February 26, 2025

androidx.media3:media3-*:1.6.0-beta01 is released. Version 1.6.0-beta01 contains these commits.

• Common Library:
  • 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.
• ExoPlayer:
  • 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.
• Transformer:
  • Add MediaProjectionAssetLoader, which provides media from a MediaProjection for screen recording, and add support for screen recording to the Transformer demo app.
  • Add #getInputFormat() to Codec interface.
  • Shift the responsibility to release the GlObjectsProvider onto the caller in DefaultVideoFrameProcessor and DefaultVideoCompositor when possible.
• Video:
  • Add experimental ExoPlayer API to drop late MediaCodecVideoRenderer decoder input buffers that are not depended on. Enable it with DefaultRenderersFactory.experimentalSetLateThresholdToDropDecoderInputUs.
• Session:
  • Keep foreground service state for an additional 10 minutes when playback pauses, stops or fails. This allows users to resume playback within this timeout without risking foreground service restrictions on various devices. Note that calling player.pause() can no longer be used to stop the foreground service before stopSelf() when overriding onTaskRemoved, use MediaSessionService.pauseAllPlayersAndStopSelf() instead.
  • Keep notification visible when playback enters an error or stopped state. The notification is only removed if the playlist is cleared or the player is released.
  • Improve handling of Android platform MediaSession actions ACTION_PLAY and ACTION_PAUSE to only set one of them according to the available commands and also accept if only one of them is set.
• Remove deprecated symbols:
  • Removed the following deprecated DownloadHelper methods:
    • Constructor DownloadHelper(MediaItem, @Nullable MediaSource, TrackSelectionParameters, RendererCapabilities[]), use DownloadHelper(MediaItem, @Nullable MediaSource, TrackSelectionParameters, RendererCapabilitiesList) instead.
    • getRendererCapabilities(RenderersFactory), equivalent behavior can be achieved by creating a DefaultRendererCapabilitiesList with a RenderersFactory, and calling DefaultRendererCapabilitiesList.getRendererCapabilities().
  • Removed PlayerNotificationManager.setMediaSessionToken(MediaSessionCompat) method. Use PlayerNotificationManager.setMediaSessionToken(MediaSession.Token) and pass in (MediaSession.Token) compatToken.getToken()instead.

androidx.benchmark:benchmark-*:1.4.0-alpha08 is released. Version 1.4.0-alpha08 contains these commits.

API Changes

• Moved TraceProcessor.runSession() extension APIs to be experimental, as they are likely to move to be concrete constructors eventually on Android. (Ib0528, b/393640753)
• Most of the implementation of Startup Insights are now public/experimental, and move to the TraceProcessor artifact See StartupInsights. (I0aa00)
• Deprecate BenchmarkRule.runWithTimingDisabled {} in favor of BenchmarkRule.runWithMeasurementDisabled {}, which more clearly describes the behavior - all metrics are paused. Additionally, expose the MicrobenchmarkScope superclass since redeclaring the runWithMeasurementDisabled function to open access isn't possible, since it's inline. (I9e23b, b/389149423, b/149979716)
• Benchmark libraries have moved to Kotlin 2.0. (I9d1e0)
• Removed androidx.benchmark.startupProfiles.enable instrumentation argument. It is no longer useful, as it can be controlled by includeInStartupProfile arg in BaselineProfileRule.collect(). (I39eb4)

Bug Fixes

• Reduced the amount of Microbenchmark internal functions called during profiling to make e.g. Method traces more clear (Ifaed8)
• Speculative fix for crashes: 'Failed to stop [ProcessPid(processName=perfetto, pid=...)]'. Now Benchmark will log a message instead of crashing when a background Perfetto process isn't able to be stopped before running the benchmark. (I37d3e, b/323601788)
• Fix IllegalStateExceptions with 'Expected pm dump-profiles stdout' label that were caused by overly strict output format check. (I358dc)

Media3: v1.6.0-alpha02

January 30, 2025

androidx.media3:media3-*:1.6.0-alpha02 is released. Version 1.6.0-alpha02 contains these commits.

• Common Library:
  • Fix bug in SimpleBasePlayer where setting a new currentMediaItemIndex in State after setPlaylist with null MediaMetadata does not reevaluate the metadata (#1940).
• ExoPlayer:
  • Add experimental 'ExoPlayer' pre-warming support for playback using MediaCodecVideoRenderer. 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.
  • Fix issue where additional decode-only frames may be displayed in quick succession when transitioning to content media after a mid-roll ad.
  • Make DefaultRenderersFactory add two MetadataRenderer instances to enable apps to receive two different schemes of metadata by default.
  • 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.
  • Reevaluate whether the ongoing load of a chunk should be cancelled when playback is paused (#1785).
• Transformer:
  • Enable support for Android platform diagnostics using MediaMetricsManager. Transformer forwards editing events and performance data to the platform, which helps to provide system performance and debugging information on the device. This data may also be collected by Google if sharing usage and diagnostics data is enabled by the user of the device. Apps can opt-out of contributing to platform diagnostics for Transformer with Transformer.Builder.setUsePlatformDiagnostics(false).
  • Split InAppMuxer into InAppMp4Muxer and InAppFragmentedMp4Muxer. You use InAppMp4Muxer to produce a non-fragmented MP4 file, while InAppFragmentedMp4Muxer is for producing a fragmented MP4 file.
  • Move Muxer interface from media3-muxer to media3-transformer.
  • Add support for transcoding and transmuxing Dolby Vision (profile 8) format.
• Extractors:
  • Fix handling of NAL units with lengths expressed in 1 or 2 bytes (rather than 4).
  • Fix ArrayIndexOutOfBoundsException in MP4 edit lists when the edit list starts at a non-sync frame with no preceding sync frame (#2062).
• Audio:
  • Don't bypass SonicAudioProcessor when SpeedChangingAudioProcessor is configured with default parameters.
  • Fix underflow in Sonic#getOutputSize() that could cause DefaultAudioSink to stall.
  • Fix MediaCodecAudioRenderer.getDurationToProgressUs() and DecoderAudioRenderer.getDurationToProgressUs() so that seeks correctly reset the provided durations.
• Text:
  • TTML: Add support for referencing tts:origin and tts:extent using style (#2953).
  • Restrict WebVTT and SubRip timestamps to exactly 3 decimal places. Previously we incorrectly parsed any number of decimal places but always assumed the value was in milliseconds, leading to incorrect timestamps (#1997).
  • Add support for VobSub subtitles (#8260).
  • Fix playback hanging when a playlist contains clipped items with CEA-608 or CEA-708 captions.
  • Fix IllegalStateException when an SSA file contains a cue with zero duration (start and end time equal) (#2052).
  • Suppress (and log) subtitle parsing errors when subtitles are muxed into the same container as audio and video (#2052).
• Muxers:
  • Renamed setSampleCopyEnabled() method to setSampleCopyingEnabled() in both Mp4Muxer.Builder and FragmentedMp4Muxer.Builder.
  • Mp4Muxer.addTrack() and FragmentedMp4Muxer.addTrack() now return an int track ID instead of a TrackToken.
  • Mp4Muxer and FragmentedMp4Muxer no longer implement Muxer interface.
• Session:
  • Fix bug where calling a Player method on a MediaController connected to a legacy session dropped changes from a pending update.
• UI:
  • Add PresentationState state holder class and the corresponding rememberPresentationState Composable to media3-ui-compose.
• HLS Extension:
  • Parse SUPPLEMENTAL-CODECS tag from HLS playlist to detect Dolby Vision formats (#1785).
• DASH Extension:
  • Fix issue when calculating the update interval for ad insertion in multi-period live streams (#1698).
  • Parse scte214:supplementalCodecs attribute from DASH manifest to detect Dolby Vision formats (#1785).
  • Improve handling of period transitions in live streams where the period contains media samples beyond the declared period duration (#1698).
• Demo app:
  • Use PresentationState to control the aspect ratio of PlayerSurface Composable. This depends on the ContentScale type and covers it with a shutter-overlay before the first frame is rendered.
• Remove deprecated symbols:
  • Removed ExoPlayer.VideoComponent, ExoPlayer.AudioComponent, ExoPlayer.TextComponent and ExoPlayer.DeviceComponent.
