androidx/media 1.9.1

on GitHub

This release includes the following changes since 1.9.0 release:

• Common Library:
  • Support date-time strings with only hours in the timezone offset (#2929).
• ExoPlayer:
  • Allow dynamic scheduling to slow doSomeWork interval only after audio starts to support smoother A/V sync at beginning of playback.
  • Fix bug in DefaultLoadErrorHandlingPolicy where FileNotFoundException and similar exception types were retried multiple times.
  • Fix bug with dynamic scheduling where the calculated time for the next doSomeWork was mistakenly reduced by the elapsed time of the current iteration of doSomeWork. Addressing this hopefully extends CPU idle time and saves power.
  • Fix issue where some playbacks of Dolby Vision files fail when attempting to use a fallback AVC or HEVC codec.
  • Fix bug where loading continues after playback ended when removing the currently playing item from a playlist (#2873).
  • Avoid leaking MediaItem instances when repeatedly using ExoPlayer.replaceMediaItem on the same item (#2993).
  • Prevent potential ANRs caused by emergency wake lock releases (#2979).
• Extractors:
  • MP3: Parse LAME ReplayGain data (#2840).
• Audio:
  • Correctly remove support for AC4Profile22 and other legacy profiles when assessing AC-4 decoder support in Automotive scenarios (#2609).
• Video:
  • Discard video codecs on devices below API 30 when the content frame rate changes to avoid stuttering playback (#2941).
• Text:
  • VobSub: Fix some missing subtitles by correctly handling SPUs that either contain only a single control sequence, or have critical info split across multiple control sequences (#2935).
• IMA extension:
  • Bug fix: Corrected an issue where the ad MIME type did not match the MIME type provided in the IMA LOADED event. The fix now maps the ad MIME type using the ad pod index and ad position.
  • Add a null check before accessing result of getAdsManager() and AdEvent.getAd().
• Session:
  • Fix bug where stopping a MediaController connected to a platform session crashed the app if stop happened during ad playback (#2948).
  • Add additional verifications on extras Bundle instances in various classes to guard against malformed Bundle instances sent from other processes.
  • Fix issue where missing commands for COMMAND_SEEK_NEXT or COMMAND_SEEK_BACK can cause gaps in the system media notification (#2976).
  • Move bitmap scaling for notification icon off the main thread (#2829).
  • Fix bug where author, writer and composer were not used as a fallback when converting from legacy MediaMetadataCompat and MediaDescriptionCompat (#3018).
• Downloads:
  • Fix potential infinite loops when a PriorityTooLowException is handled by SegmentDownloader (for DASH, HLS and SmoothStreaming). Custom overrides of SegmentDownloader using the protected execute method need to provide their task wrapped in a Supplier so it can be recreated (#2931).
• HLS extension:
  • Pass the raw asset list JSON document to Listener.onAssetListLoadCompleted callback. This is a breaking change in an unstable API that requires apps that implement this callback to add an additional argument of type JSONObject (#2950).
• RTSP extension:
  • Correctly handle RTP Packets with timestamps that wrap around (#2930).
• Decoder extensions (FFmpeg, VP9, AV1, etc.):
  • Fix potential NullPointerException that can occur when seeking prior to processing the first video frame (#2965).
• Cast extension:
  • Fix bug preventing the RemoteCastPlayer timeline from updating correctly when replacing the playlist.
