This typically happens if there's a discontinuity in the stream.
It's better to say we don't know, than it is to return a negative
position.

Extractor was not calling endTracks() and seekMap() on the
extractorOutput which are required to finish the preparation.
At that point extractor does not support seeking.

Samples are serialized using our custom CueEncoder. Information in
which format samples are encoded is needed by Renderer to decide which
decoder to use. Extractor receives Format object in the constructor and
prepares new Format object with sampleMimeType moved to codecs field
and new sampleMimeType set to "custom serialized exoplayer Cue".

SubtitleExtractor.release() releases the underlying SubtitleDecoder.
This change introduces the STATE_RELEASED state. The extractor
handles the new state in the read() and seek() methods.
PiperOrigin-RevId: 391046478
SubtitleExtractor is a component that extracts subtitle data taken from
ExtractorInput into samples. Samples are pushed into an ExtractorOutput
(usually SampleQueue). As a temporary solution SubtitleExtractor uses
SubtitleDecoder to extract Cues from input data.

- Fix use of getTimestampOffsetUs in TsExtractor where
getFirstSampleTimestampUs should have been used.
- Don't reset TimestampAdjuster if it's in no-offset mode.
- Improve comment clarity

- Use timestampOffsetUs == C.TIME_UNSET directly as the way of
determining whether the adjuster has determined the offset,
rather than relying on lastSampleTimestampUs checks for this.
- Remove comment referring to lastSampleTimestampUs as holding
the "adjusted PTS". Its value may not have originated from a PTS
timestamp. It's also confusing to refer to it as "adjusted"
given timestampOffsetUs has not been applied to it.
- Fix PassthroughSectionPayloadReader to make sure it'll never
output a sample with an unset timestamp.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.
Notable renamings that might be controversial:
- `onPlaybackStateChanged(int state)` to `onPlaybackStateChanged(int playbackState)` affected a lot of lines but seems more consistent with other '-Changed' methods.
- `handleMessage(int messageType, Object payload)` to `handleMessage(int messageType, Object message)`
- `ExtractorInput` and `DataSource` inherit `DataReader` which had `read(byte[] target, ...`, while data sources normally called the first parameter `buffer`. I have standardized these all to use `buffer` even though it looks out of place in the `ExtractorInput` interface (which has more `read` methods with `target`).

Note that this removes a workaround for malformed content, in which the
track_ID is set incorrectly. It's unclear there was sufficient reason to
implement that workaround, and so it's preferable to remove it, rather
than implementing the concept of unrecognized tracks, which would be
needed to keep it and to also fix this issue.

Unlike Assertions, the introduced method cannot be disabled and throws
a ParserException instead. This method is meant to replace regular
assertions (which throw RuntimeExceptions) which check input in the
parsing code.

First intention to support parsing MPEG-H 3D Audio in ExoPlayer is to
take advantage of parsing capability from MediaParser API in AOSP.
Just with this change ExoPlayer does't support decoding MPEG-H 3D Audio
but can support decoding either by adding decoder with an extension or
by using Android OS which has decoder capability with MediaCodec API.
A TrackGroup must contain the same content in all Formats (except for
the quality, encoding etc). Verify that the language and role flags
are the same and log an error if don't match. Don't throw to avoid
breaking existing use cases that just happen to work by chance.

Fix Matroska, Heif, FLAC, Ogg, Opus, Vorbis
extractor nullness check.
There should be no functional change.
Every media that fail to be parsed should still fail.
Every media that parsed successfully should still succeed.
This refactor aims to push all nullness constraints up the call stack to clarify each API nullness contract. This ensures implementation and caller have to prove their respective contract close to where such logic is implemented. This also allows to fail early if an nullness contract is broken instead of deep in the call stack.
For example, by adding a requirement that all implementation of `StreamReader.readHeaders` have to initialize `setupData.format` if the return false, each overriding method is forced to prove this next to the logic initializing it. This also means the runtime check might not be needed because the nullnessChecker can prove itself the contract holds.
This is in contrast with adding a null check at the point of usage, which will not catch logic errors where they are produce, but later when they are perceived; making it harder to debug and catching the issue at run time instead of compile time.

This was reported for SSA/ASS in PR #8265, but it seems to me the
SubRip part of the Matroska spec is similarly loose, so this change

This method should be assumed to clear the data of the underlying array
(it will do this if the new limit > data.length).
This means it should only be called (directly) before writing into the
backing array.
It shouldn't be used as a shorthand for position=0, limit=x - those
should be two explicit method calls.
Most of these changes are no-ops, but they make the code more correct.
The TS SectionReader can't be easily changed to be 'safe', because it
relies on sectionData maintaining state between iterations of the while
loop. Instead I've added comments justifying the existing code.

This ensures we have full test coverage for proguard configs now.
The only configs not covered by tests are:
- IMA and OkHttp which copy recommended configs from the respective
library. I couldn't reproduce failures by removing them (and thus
couldn't write a test that ensures they are correct).
- Some dontwarn lines that just suppress warnings.
In addition, this change fixes a couple of related issues:
- Moved AV1 proguard config to correct module.
- Removed mentioning of deprecated ExtractorMediaSource from README
- Suppressed warning from IMA code that prevent proguarding under
strict rules
- Fixed wrong proguard exclusion in VP9 module.
- Moved FLAC exclusion (DefaultExtractorsFactory) to correct module.
- Added AlertDialog suppression for de-jetified code.
- Removed unusued dependency from UI module that causes large APK
size increase.
