* Add Java FLAC extractor * Add Java FLAC extractor
([#6406](https://github.com/google/ExoPlayer/issues/6406)). ([#6406](https://github.com/google/ExoPlayer/issues/6406)).
This extractor does not support seeking and live streams, and does not expose
vorbis, ID3 and picture data. If `DefaultExtractorsFactory` is used, this
extractor is only used if the FLAC extension is not loaded.

This extractor does not support seeking and live streams. If
`DefaultExtractorsFactory` is used, this extractor is only used if the FLAC
extension is not loaded.
* Video tunneling: Fix renderer end-of-stream with `OnFrameRenderedListener`
from API 23, tunneled renderer must send a special timestamp on EOS.
Previously the EOS was reported when the input stream reached EOS.
* Require an end time or duration for SubRip (SRT) and SubStation Alpha
(SSA/ASS) subtitles. This applies to both sidecar files & subtitles
[embedded in Matroska streams](https://matroska.org/technical/specs/subtitles/index.html).
* Use `ExoMediaDrm.Provider` in `OfflineLicenseHelper` to avoid `ExoMediaDrm`
leaks ([#4721](https://github.com/google/ExoPlayer/issues/4721)).
* Improve `Format` propagation within the `MediaCodecRenderer` and subclasses.
For example, fix handling of pixel aspect ratio changes in playlists where
video resolution does not change.
([#6646](https://github.com/google/ExoPlayer/issues/6646)).
* Rename `MediaCodecRenderer.onOutputFormatChanged` to
`MediaCodecRenderer.onOutputMediaFormatChanged`, further
clarifying the distinction between `Format` and `MediaFormat`.
* Fix byte order of HDR10+ static metadata to match CTA-861.3.
* Reconfigure audio sink when PCM encoding changes
([#6601](https://github.com/google/ExoPlayer/issues/6601)).
* Make `MediaSourceEventListener.LoadEventInfo` and
`MediaSourceEventListener.MediaLoadData` top-level classes.
