and `LibopusAudioRenderer`.
* Do not use a MediaCodec for PCM formats if AudioTrack supports it.
* DASH:
* Enable support for embedded CEA-708.
* Add support for load cancelation when discarding upstream
* Add support for canceling in-progress segment fetches
([#2848](https://github.com/google/ExoPlayer/issues/2848)).
* Add support for CEA-708 embedded in FMP4.
* SmoothStreaming:
* Add support for canceling in-progress segment fetches
([#2848](https://github.com/google/ExoPlayer/issues/2848)).
* HLS:
* Add support for upstream discard including cancelation of ongoing load
* Add support for discarding buffered media (e.g., to allow faster
adaptation to a higher quality variant)
([#6322](https://github.com/google/ExoPlayer/issues/6322)).
* Add support for canceling in-progress segment fetches
([#2848](https://github.com/google/ExoPlayer/issues/2848)).
* Respect 33-bit PTS wrapping when applying `X-TIMESTAMP-MAP` to WebVTT
timestamps ([#7464](https://github.com/google/ExoPlayer/issues/7464)).
* Ogg: Allow non-contiguous pages
([#7230](https://github.com/google/ExoPlayer/issues/7230)).
* MP4: Fix playback of MP4 containing Opus.
* Matroska: Remove support for "Invisible" block header flag.
* FMP4: Fix handling of `traf` boxes containing multiple `sbgp` or `sgpd`
boxes.
* FLV: Ignore SCRIPTDATA segments with invalid name types, rather than failing
playback ([#7675](https://github.com/google/ExoPlayer/issues/7675)).
* Extractors:
* Add `IndexSeeker` for accurate seeks in VBR MP3 streams
([#6787](https://github.com/google/ExoPlayer/issues/6787)). This seeker
is enabled by passing `FLAG_ENABLE_INDEX_SEEKING` to the `Mp3Extractor`.
It may require to scan a significant portion of the file for seeking,
which may be costly on large files.
* Change the order of extractors for sniffing to reduce start-up latency
* Optimize the `Extractor` sniffing order to reduce start-up latency
in `DefaultExtractorsFactory` and `DefaultHlsExtractorsFactory`
([#6410](https://github.com/google/ExoPlayer/issues/6410)).
* Select first extractors based on the filename extension and the response
headers mime type in `DefaultExtractorsFactory`.
* Add support for partially fragmented MP4s
([#7308](https://github.com/google/ExoPlayer/issues/7308)).
* Add support for MPEG-4 Part 2 and H.263 in MPEG-TS
* Use filename extensions and response header MIME types to further
optimize `Extractor` sniffing order on a per-media basis.
* MP3: Add `IndexSeeker` for accurate seeks in VBR MP3 streams
([#6787](https://github.com/google/ExoPlayer/issues/6787)). This seeker
can be enabled by passing `FLAG_ENABLE_INDEX_SEEKING` to the
`Mp3Extractor`. A significant portion of the file may need to be scanned
when a seek is performed, which may be costly for large files.
* MP4: Fix playback of MP4 streams that contain Opus audio.
* FMP4:
* Add support for partially fragmented MP4s
([#7308](https://github.com/google/ExoPlayer/issues/7308)).
* Fix handling of `traf` boxes containing multiple `sbgp` or `sgpd`
boxes ([#7716](https://github.com/google/ExoPlayer/issues/7716)).
* Matroska: Remove support for the `Invisible` block header flag.
* MPEG-TS: Add support for MPEG-4 Part 2 and H.263
([#1603](https://github.com/google/ExoPlayer/issues/1603),
[#5107](https://github.com/google/ExoPlayer/issues/5107)).
* Ogg: Fix handling of non-contiguous pages
([#7230](https://github.com/google/ExoPlayer/issues/7230)).
* FLV: Ignore `SCRIPTDATA` segments with invalid name types, rather than
failing playback
([#7675](https://github.com/google/ExoPlayer/issues/7675)).
* Testing
* Add `TestExoPlayer`, a utility class with APIs to create
`SimpleExoPlayer` instances with fake components for testing.
