This avoids that these settings have to be resolved inline,
potentially blocking the main thread. They can be resolved at
the time of track selection on a background thread instead.
As a side effect, we can also remove the context parameter from
the Builder. Having the Context in the Builder is also a bad sign
in the first place because it implies the potentially blocking
calls can happen.

Moved the `getObjectType` method from `CmcdData.Factory` to `CmcdData` and updated the logic to derive the object type directly within `CmcdData`. This change eliminates the need for chunk source classes to set this value explicitly.
PiperOrigin-RevId: 705457755
- Moved static fields for object type, stream type, etc. from `CmcdData.Factory` to `CmcdData`.
- Removed redundant `CmcdData` prefix from `@ObjectType` and `@StreamingFormat` annotations.

This affects both `AnalyticsListener` and `MediaSourceEventListener`
This was introduced by d051b4b993
Also fix a missing 'load started' event for HLS media playlists (this
was also introduced by d051b4b993).

- Added logic to parse media duration from the `mdhd` box for accurate frame rate calculation.
- Fallbacks to track duration from `tkhd` when `mdhd` contains invalid or missing data.
- Avoids incorrect frame rate calculations in MP4 files with an edit list (`elst`) box.
- Adds frame rate calculations for partially fragmented MP4 files.
- Verified accuracy with tools like `mediainfo` and `ffprobe`.
Issue: androidx/media#1531
**Note**: The slight difference in frame rate values in dump files that aren’t MP4s with an edit list or fragmented MP4s isn’t due to differences in `tkhd` and `mdhd` duration values (which should be identical for non-edited or non-fragmented files). Rather, it’s because they are calculated using different timescales. The `mvhd` box defines a global movie timescale, which is used for the track's `tkhd` duration. Meanwhile, each track’s `mdhd` box defines its own timescale specific to its content type, which we now use for more accurate frame rate calculation.

DASH periods don't have to start at the beginning of a segment. In
these cases, they should report an initial discontinuity to let the
player know it needs to expect preroll data (e.g. to flush renderers)
This information is only available in the ChunkSampleStream after
loading the initialization data, so we need to check the sample
streams and tell them to only report discontinuities at the very
beginning of playback. All other position resets are triggered by
the player itself and don't need this method.

To override this change, and go back to parsing during rendering,
apps must make two method calls:
1. `MediaSource.Factory.experimentalParseSubtitlesDuringExtraction(false)`
2. `TextRenderer.experimentalSetLegacyDecodingEnabled(true)`

DASH: `DashMediaSource.Factory` would only propagate it to `DashChunkSource.Factory` -> `BundledChunkExtractor.Factory`
SS: `SSMediaSource.Factory` -> `SsChunkSource.Factory`
HLS: `HlsMediaSource.Factory` -> `HlsExtractorFactory`
Remove nullability of SubtitleParser.Factory across the stack
#minor-release
PiperOrigin-RevId: 601250013
The `SubtitleParser.Factory` is no longer @Nullable and the experimenting toggle is used to enable/disable the use of this factory for subtitle parsing during extraction.
The three places that will hold the "truth" for the `SubtitleParser.Factory` are: BundledChunkExtractor.Factory, SsChunkSource.Factory, DefaultHlsExtractorFactory
DASH: `DashMediaSource.Factory` would only propagate it to `DashChunkSource.Factory` -> `BundledChunkExtractor.Factory`

Those classes only needed to have access to a `SubtitleParser.Factory` to get a potentially updated `Format` for TrackGroups. The `SubtitleParser.Factory` was only used to check the support for the `mimeType` and getting some cue-related behaviour.
This introduced complexity in a way that both Periods and Extractors needed to have the same `SubtitleParser.Factory` in their individual stacks. To ensure that the sample queue would get the same transcoded/original format.
Instead, now we expose `getOutputTextFormat` methods on `ChunkExtractor.Factory`, `SsChunkSource.Factory` and `HlsExtractorFactory`. Those are the dependencies that Hls/Ss/DashMediaPeriod can make use of to delegate the format-updating logic to.

We introduce SubtitleParser.Factory that supports no formats to be used FragmentedMp4Extractors that will not do any subtitle parsing on the extraction side. We also slowly move away from using SubtitleTranscodingExtractor to SubtitleTranscodingExtractorOutput (hence making it public).
This is required by individual Extractor impls so that they can start using SubtitleTranscodingExtractorOutput rather than be wrapped by SubtitleTranscodingExtractor. The latter is to be deprecated after all the subtitle related Extractors have achieved this migration.

When track is changed during playback, `playbackPositionUs` may be in middle of a chunk and `loadPositionUs` should be the start of that chunk. In this situation `loadPositionUs` can be less than the current `playbackPositionUs`, resulting into negative `bufferedDurationUs`. It translates to having no buffer and hence we should send `0` for `bufferedDurationUs` when creating new instances of `CmcdData.Factory`.

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.

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.

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.
