## 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)).
