r2.14.1

• Core Library:
  • Fix gradle config to allow specifying a relative path for exoplayerRoot when depending on ExoPlayer locally
    (#8927).
  • Update MediaItem.Builder javadoc to discourage calling setters that will be (currently) ignored if another setter is not also called.
• Extractors:
  • Add support for MPEG-H 3D Audio in MP4 extractors (#8860).
• Video:
  • Fix bug that could cause CodecException: Error 0xffffffff to be thrown from MediaCodec.native_setSurface in use cases that involve both swapping the output Surface and a mixture of secure and non-secure content being played (#8776).
• HLS:
  • Use the PRECISE attribute in EXT-X-START to select the default start position.
  • Fix a bug where skipping into spliced-in chunks triggered an assertion error (#8937).
• DRM:
  • Keep secure MediaCodec instances initialized when disabling (but not resetting) MediaCodecRenderer. This helps re-use secure decoders in more contexts, which avoids the 'black flash' caused by detaching a Surface from a secure decoder on some devices (#8842). It will also result in DRM license refresh network requests while the player is stopped if Player#setForegroundMode is true.
  • Fix issue where offline keys were unnecessarily (and incorrectly) restored into a session before being released. This call sequence is explicitly disallowed in OEMCrypto v16.
• UI:
  • Keep subtitle language features embedded (e.g. rubies & tate-chu-yoko) in Cue.text even when SubtitleView#setApplyEmbeddedStyles() is false.
  • Fix NullPointerException in StyledPlayerView that could occur after calling StyledPlayerView.setPlayer(null) (#8985).
• RTSP:
  • Add support for RTSP basic and digest authentication (#8941).
  • Enable using repeat mode and playlist with RTSP (#8994).
  • Add RtspMediaSource.Factory option to set the RTSP user agent.
  • Add RtspMediaSource.Factory option to force using TCP for streaming.
• GL demo app:
  • Fix texture transformation to avoid green bars shown on some videos (#8992).
