Media3: v1.0.0-alpha02

March 2, 2022

androidx.media3:media3-*:1.0.0-alpha02 is released. Version 1.0.0-alpha02 contains these commits.

This corresponds to the ExoPlayer 2.17.0 release.

• Core Library:
  • Add protected method DefaultRenderersFactory.getCodecAdapterFactory() so that subclasses of DefaultRenderersFactory that override buildVideoRenderers() or buildAudioRenderers() can access the codec adapter factory and pass it to MediaCodecRenderer instances they create.
  • Propagate ICY header fields name and genre to MediaMetadata.station and MediaMetadata.genre respectively so that they reach the app via Player.Listener.onMediaMetadataChanged() (#9677).
  • Remove null keys from DefaultHttpDataSource#getResponseHeaders.
  • Sleep and retry when creating a MediaCodec instance fails. This works around an issue that occurs on some devices when switching a surface from a secure codec to another codec (#8696).
  • Add MediaCodecAdapter.getMetrics() to allow users obtain metrics data from MediaCodec. (#9766).
  • Fix Maven dependency resolution (#8353).
  • Disable automatic speed adjustment for live streams that neither have low-latency features nor a user request setting the speed (#9329).
  • Rename DecoderCounters#inputBufferCount to queuedInputBufferCount.
  • Make SimpleExoPlayer.renderers private. Renderers can be accessed via ExoPlayer.getRenderer.
  • Updated some AnalyticsListener.EventFlags constant values to match values in Player.EventFlags.
  • Split AnalyticsCollector into an interface and default implementation to allow it to be stripped by R8 if an app doesn't need it.
• Track selection:
  • Support preferred video role flags in track selection (#9402).
  • Update video track selection logic to take preferred MIME types and role flags into account when selecting multiple video tracks for adaptation (#9519).
  • Update video and audio track selection logic to only choose formats for adaptive selections that have the same level of decoder and hardware support (#9565).
  • Update video track selection logic to prefer more efficient codecs if multiple codecs are supported by primary, hardware-accelerated decoders (#4835).
  • Prefer audio content preferences (for example, the "default" audio track or a track matching the system locale language) over technical track selection constraints (for example, preferred MIME type, or maximum channel count).
  • Fix track selection issue where overriding one track group did not disable other track groups of the same type (#9675).
  • Fix track selection issue where a mixture of non-empty and empty track overrides is not applied correctly (#9649).
  • Prohibit duplicate TrackGroups in a TrackGroupArray. TrackGroups can always be made distinguishable by setting an id in the TrackGroup constructor. This fixes a crash when resuming playback after backgrounding the app with an active track override (#9718).
  • Amend logic in AdaptiveTrackSelection to allow a quality increase under sufficient network bandwidth even if playback is very close to the live edge (#9784).
• Video:
  • Fix decoder fallback logic for Dolby Vision to use a compatible H264/H265 decoder if needed.
• Audio:
  • Fix decoder fallback logic for Dolby Atmos (E-AC3-JOC) to use a compatible E-AC3 decoder if needed.
  • Change AudioCapabilities APIs to require passing explicitly AudioCapabilities.DEFAULT_AUDIO_CAPABILITIES instead of null.
  • Allow customization of the AudioTrack buffer size calculation by injecting an AudioTrackBufferSizeProvider to DefaultAudioSink. (#8891).
  • Retry AudioTrack creation if the requested buffer size was > 1MB. (#9712).
• Extractors:
  • WAV: Add support for RF64 streams (#9543).
  • Fix incorrect parsing of H.265 SPS NAL units (#9719).
  • Parse Vorbis Comments (including METADATA_BLOCK_PICTURE) in Ogg Opus and Ogg Vorbis files.
• Text:
  • Add a MediaItem.SubtitleConfiguration.id field which is propagated to the Format.id field of the subtitle track created from the configuration (#9673).
  • Add basic support for WebVTT subtitles in Matroska containers (#9886).
  • Prevent Cea708Decoder from reading more than the declared size of a service block.
• DRM:
  • Remove playbackLooper from DrmSessionManager.(pre)acquireSession. When a DrmSessionManager is used by an app in a custom MediaSource, the playbackLooper needs to be passed to DrmSessionManager.setPlayer instead.
• Ad playback / IMA:
  • Add support for IMA Dynamic Ad Insertion (DAI) (#8213).
  • Add a method to AdPlaybackState to allow resetting an ad group so that it can be played again (#9615).
  • Enforce playback speed of 1.0 during ad playback (#9018).
  • Fix issue where an ad group that failed to load caused an immediate playback reset (#9929).
• UI:
  • Fix the color of the numbers in StyledPlayerView rewind and fastforward buttons when using certain themes (#9765).
  • Correctly translate playback speed strings (#9811).
• DASH:
  • Add parsed essential and supplemental properties to the Representation (#9579).
  • Support the forced-subtitle track role (#9727).
  • Stop interpreting the main track role as C.SELECTION_FLAG_DEFAULT.
  • Fix base URL exclusion logic for manifests that do not declare the DVB namespace (#9856).
  • Support relative MPD.Location URLs (#9939).
• HLS:
  • Correctly populate

• Use PowerManager for thermal throttling detection on Q (API 29) and higher. This significantly reduces frequency of false positives in thermal throttling detection (benchmark retry after 90 second cooldown), and speeds up benchmarks significantly on user builds. It also provides throttle detection even when clocks are locked (if they're locked too high for the device's physical environment). (I9c027, b/217497678, b/131755853)

• Filter simpleperf sampled profiling to measureRepeated thread only to simplify inspection (Ic3e12, b/217501939)

• @OpenForTesting (b/141539024): Kotlin classes and methods marked "open" can be annotated with this annotation, and lint will make sure that this class is only subclassed (and methods only overridden) from unit tests

• @DeprecatedSinceApi (b/37116481): Indicates that the annotated method (or class or field) is part of a backport library for a platform API, which is no longer needed as of the given API level.

• @EmptySuper: Indicates that this method is defined to be empty, so when overriding you do not need to call it (and in fact you shouldn't; for example, it can contain backwards compatibility checking.)

Benchmark: v1.1.0-beta03

February 9, 2022

androidx.benchmark:benchmark-*:1.1.0-beta03 is released. Version 1.1.0-beta03 contains these commits.

API Changes

• Added AudioUnderrunMetric into macrobenchmark library under experimental flag to allow detection of audio underruns (Ib5972)

• BaselineProfileRule no longer accepts a setup block as this functioned the same as the profileBlock. (Ic7dfe, b/215536447)

  For e.g.

  @Test
  fun collectBaselineProfile() {
      baselineRule.collectBaselineProfile(
          packageName = PACKAGE_NAME,
          setupBlock = {
              startActivityAndWait()
          },
          profileBlock = {
              // ...
          }
      )
  }
  

  @Test
  fun collectBaselineProfile() {
      baselineRule.collectBaselineProfile(
          packageName = PACKAGE_NAME,
          profileBlock = {
              startActivityAndWait()
              // ...
          }
      )
  }
  

Bug Fixes

• Fixed issue where microbench profiler traces would fail to be updated in subsequent runs when linked in Studio output (I5ae4d, b/214917025)
• Prevent compilation shell commands on API 23 (Ice380)
• Renamed FrameCpuTime -> FrameDurationCpu, FrameUiTime -> FrameDurationUi to clarify these are durations, not timestamps, and to match prefixes. (I0eba3, b/216337830)

Compose Animation: v1.1.0

February 9, 2022

androidx.compose.animation:animation:1.1.0, androidx.compose.animation:animation-core:1.1.0, and androidx.compose.animation:animation-graphics:1.1.0 are released. Version 1.1.0 contains these commits.

Important changes since 1.0.0

• Stable support for the Android 12 Overscroll effect
• Improvements to touch target sizing
• Note that, with respect to Compose 1.0, Material components will expand their layout space to meet Material accessibility guidelines for touch target size. For instance, Button touch target will expand to a minimum size of 48x48dp, even if you set the Button's size to be smaller. This aligns Compose Material to the same behavior of Material Design Components, providing consistent behavior if you mix Views and Compose. This change also ensures that when you create your UI using Compose Material components, minimum requirements for touch target accessibility will be met.
• Stable support for Navigation Rail
• Graduates a number of previously experimental APIs to stable
• Support for newer versions of Kotlin

New Features

• ComponentActivity now integrates with ViewModel CreationExtras, introduced as part of Lifecycle 2.5.0-alpha01. (Ie7e00, b/207012584)
• Added ComponentDialog, a subclass of Dialog that includes an OnBackPressedDispatcher that will be called when the system back button is pressed when the dialog is visible. Importantly, this subclass also sets the ViewTreeOnBackPressedDispatcherOwner, allowing views a generic way to retrieve the correct dispatcher whether it exists in a ComponentActivity or a ComponentDialog. (I8a1bc)
• ComponentActivity now implements the new OnNewIntentProvider interface to allow any component to receive these events. (If1f8b)
• ComponentActivity now implements the new OnConfigurationChangedProvider interface to allow any component to receive these events. (If623b)
