## 1.3

### 1.3.0-rc01 (2024-02-22)

This release includes the following changes since the
[1.3.0-beta01 release](#130-beta01-2024-02-07):

* ExoPlayer:
* Add source prefix to all `Format.id` fields generated from
`MergingMediaSource`. This helps to identify which source produced a
`Format` ([#883](/~https://github.com/androidx/media/issues/883)).
* Fix the regex used for validating custom Common Media Client Data (CMCD)
key names by modifying it to only check for hyphen
([#1028](/~https://github.com/androidx/media/issues/1028)).
* Stop double-encoding CMCD query parameters
([#1075](/~https://github.com/androidx/media/issues/1075)).
* Audio:
* Improve silence skipping algorithm with smooth volume ramp; retained
minimal silence and more natural silence durations
([#7423](/~https://github.com/google/ExoPlayer/issues/7423)).
* Report the skipped silence more deterministically
([#1035](/~https://github.com/androidx/media/issues/1035)).
* Session:
* Fix issue where `MediaItem.RequestMetadata` with just non-null extras is
not transmitted between media controllers and sessions.
* Add constructor to `MediaLibrarySession.Builder` that only takes a
`Context` instead of a `MediaLibraryService`.
* HLS Extension:
* Resolve seeks to beginning of a segment more efficiently
([#1031](/~https://github.com/androidx/media/pull/1031)).

### 1.3.0-beta01 (2024-02-07)

This release includes the following changes since the
[1.3.0-alpha01 release](#130-alpha01-2024-01-15):

* Common Library:
* Populate both `artworkUri` and `artworkData` in
`MediaMetadata.Builder.populate(MediaMetadata)` when at least one of
them is non-null ([#964](/~https://github.com/androidx/media/issues/964)).
* ExoPlayer:
* Prevent subclassing `CompositeSequenceableLoader`. This component was
[previously made extensible](/~https://github.com/androidx/media/commit/0de57cbfae7165dd3bb829e323d089cd312b4b1b)
but was never subclassed within the library. Customizations can be done
by wrapping an instance using the
[decorator pattern](https://en.wikipedia.org/wiki/Decorator_pattern) and
implementing a custom `CompositeSequenceableLoaderFactory`.
* Fix issue where repeating the same time causes metadata from this item
to be cleared ([#1007](/~https://github.com/androidx/media/issues/1007)).
* Rename `experimentalSetSubtitleParserFactory` methods on
`BundledChunkExtractor.Factory` and `DefaultHlsExtractorFactory` to
`setSubtitleParserFactory` and disallow passing `null`. Use the new
`experimentalParseSubtitlesDuringExtraction(boolean)` methods to control
parsing behaviour.
* Add support for customising the `SubtitleParser.Factory` used during
extraction. This can be achieved with
`MediaSource.Factory.setSubtitleParserFactory()`.
* Extractors:
* MP3: Use constant bitrate (CBR) seeking for files with an `Info` header
(the CBR equivalent of the `Xing` header). Previously we used the seek
table from the `Info` header, but this results in less precise seeking
than if we ignore it and assume the file is CBR.
* MPEG2-TS: Add DTS, DTS-LBR and DTS:X Profile2 support
([#275](/~https://github.com/androidx/media/pull/275)).
* Extract audio types from TS descriptors and map them to role flags,
allowing users to make better-informed audio track selections
([#973](/~https://github.com/androidx/media/pull/973)).
* Image:
* Add support for DASH thumbnails. Grid images are cropped and individual
thumbnails are provided to `ImageOutput` close to their presentation
times.
* Session:
* Disable double-click detection for TV apps
([#962](/~https://github.com/androidx/media/issues/962)).
