Unfortunately we can't fail any more obviously at this point, because
manifests often contain config for multiple DRM schemes, and when
parsing the manifest we don't know which scheme is going to be used for
playback. It would be unreasonable to fail playback due to incomplete
ClearKey config if playback was otherwise going to succeed using e.g.
Widevine.

This change applies to standalone WebVTT files linked directly from the manifest.
Since DASH only supports stand-alone IMSC1 (TTML) and WebVTT text files, this change concludes the support extension of text-based subtitle files to be parse during extraction.
PiperOrigin-RevId: 577468830
This change applies to standalone TTML files linked directly from the manifest.
As a result, we no longer have the flakiness in the DashPlaybackTest which uses sidecar-loaded (standalone file) TTML subtitles. We experimentally opt into parsing subtitles during extraction and use SubtitleExtractor in hybrid mode.

This currently only applies to subtitles muxed into mp4 segments, and
not standalone text files linked directly from the manifest.
Issue: androidx/media#288

PiperOrigin-RevId: 572263764
The test is hidden behind the Ignore annotation due to some flakiness just like `webvttInMp4`. However, it will be removed when the subtitle parsing is moved to a pre-sample-queue architecture.

Currently, we only support sending Common Media Client Data (CMCD) data through custom HTTP request headers, added capability to configure and transmit it as HTTP query parameters.
PiperOrigin-RevId: 561591246
Based on the Common Media Client Data (CMCD) specification key-value pairs should be sequenced in alphabetical order of the key name in order to reduce the fingerprinting surface exposed by the player.
PiperOrigin-RevId: 558296264
Added more comprehensive Javadoc around setting custom data and verification on key format.
Changed adding custom data as a `String` to `List<String>`. This would enable us to sort all keys to reduce the fingerprinting surface.

Modifies the `ChunkSource.getNextChunk(long, long, List, ChunkHolder)` method in the `ChunkSource` interface to `ChunkSource.getNextChunk(LoadingInfo, long, List, ChunkHolder)`.
LoadingInfo contains additional parameters, including `playbackRate` and `lastRebufferRealtimeMs` in addition to the existing `playbackPositionUs`. The additional parameters will allow us to pass these information to Common Media Client Data (CMCD) logging.
PiperOrigin-RevId: 555148768
Modifies the `SequenceableLoader.continueLoading(long)` method in the `SequenceableLoader` interface to `SequenceableLoader.continueLoading(LoadingInfo)`.
`LoadingInfo` contains additional parameters, including `playbackSpeed` and `lastRebufferRealtimeMs` in addition to the existing `playbackPositionUs`. The additional parameters will allow us to pass these information to Common Media Client Data (CMCD) logging.
By using the `LoadingInfo` object, we ensure future flexibility to add more fields without causing any breaking changes to the API.

Periods that are not the last in the manifest are always ended
and non-dynamic periods are also always ended by definition.
Also, some periods may not be able to declare their final duration
accurately and we need to account for some inaccuracy. This can be
done by testing whether no further full segment within the duration
can be expected.
Refactored `CmcdLog` to `CmcdHeadersFactory` for improved representation of its purpose and updated implementations.
#minor-change
PiperOrigin-RevId: 552831995
Updated `ExoTrackSelection` to provide the most recent bitrate estimate, enabling the inclusion of measured throughput (mtp) as a CMCD-Request field in Common Media Client Data (CMCD) logging.
Additionally, made changes to the `checkArgument` methods in `CmcdLog` to prevent the use of default values in certain cases.

This changes all MediaSources in our library to allow updates to
their MediaItems (if supported).

This avoids issues with potential number clashes with ID_UNSET.
Also fixes some further parsing where adaptation set ids are referenced
from manifest properties.
MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

Instead of providing `playbackDurationUs` and `loadPositionUs` individually, which are used to calculate the buffer duration for CMCD logging, we can directly pass the pre-calculated `bufferedDurationUs` available in the `getNextChunk` method of the chunk source classes.

Additionally, two existing methods to `buildDataSpec` in `DashUtil` have been deprecated, while a new method has been added that allows the inclusion of `httpRequestHeaders`.

The existing NullableType has been deprecated 5 years ago and causes
crashes in Kotlin apps because Kotlin doesn't recognize this annotation
as a nullable type annotation.
While we can't align on a single @Nullable annotation yet, we can at
least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all
requirements, including full Kotlin compatiblity. To avoid the
cumbersome name, we can redefine it as our own @NullableType
annotation. (We can't use @Nullable to avoid name clashes with the main
@Nullable annotation from AndroidX)

When the source is prepared again after stop, the period uid
is calculated by subtracting the `firstPeriodId` from the
period uid that is passed in to `createPeriod`. When this
happens after stop, the uid from the old period uid that
is still stored and has the value of the last played uid.
Hence the `firstPeriodId` must not be reset when released.
Issue: google/ExoPlayer#10838
PiperOrigin-RevId: 539028570
Add support for including Common Media Client Data (CMCD) in the outgoing requests of adaptive streaming formats DASH, HLS, and SmoothStreaming.
API structure and API methods:
* CMCD logging is disabled by default, use `MediaSource.Factory.setCmcdConfigurationFactory(CmcdConfiguration.Factory cmcdConfigurationFactory)` to enable it.
* All keys are enabled by default, override `CmcdConfiguration.RequestConfig.isKeyAllowed(String key)` to filter out which keys are logged.
* Override `CmcdConfiguration.RequestConfig.getCustomData()` to enable custom key logging.
NOTE: Only the following fields have been implemented: `br`, `bl`, `cid`, `rtp`, and `sid`.
