- Added back parsing of scheme data for version 1 as it's technically
allowed by the spec.
- Made constructor of PsshAtom private to only publish the data class
and not the constructor.
- Formatting and Javadoc adjustments
- Additional tests
Many usages are needed to support other deprecations and some
can be replaced by the recommended direct alternative.
Also replace links to deprecated/redirected dev site

It's likely that we will merge these back into their `XXXDecoder`
implementations, but this smaller change allows us to avoid including
these public symbols in the upcoming release.

MatroskaExtractor will no longer be wrapped in SubtitleTranscodingExtractor, but instead use SubtitleTranscodingExtractorOutput under the hood.
FLAG_EMIT_RAW_SUBTITLE_DATA flag will be used to toggle between subtitle parsing during extraction (before the sample queue) or during decoding (after the sample queue).
The new extractor dump files generated by `MatroskaExtractorTest` now follow the new parsing logic and hence have mimeType as `x-media3-cues`.

AviExtractor supports text tracks (`AviExtractor.FOURCC_txts` -> `C.TRACK_TYPE_TEXT`) with subtitles.
AviExtractor will no longer be wrapped in SubtitleTranscodingExtractor, but instead use SubtitleTranscodingExtractorOutput under the hood.
FLAG_EMIT_RAW_SUBTITLE_DATA flag will be used to toggle between subtitle parsing during extraction (before the sample queue) or during decoding (after the sample queue).

The seek table in a Xing/Info header is very imprecise (max resolution
of 255 to describe each of 100 byte positions in the file). Seeking
using a constant bitrate assumption is more accurate, especially for
longer files (which exacerbates the imprecision of the Info header).
VBR files should contain an Xing header, while an Info header is
identical but indicates the file is CBR.

This involves promoting `setTextTranscodingEnabled` to
`ExtractorsFactory`, and also making it experimental, to indicate it's a
short-lived method.

Mp4Extractor will no longer be wrapped in SubtitleTranscodingExtractor, but instead use SubtitleTranscodingExtractorOutput under the hood.
FLAG_EMIT_RAW_SUBTITLE_DATA flag will be used to toggle between subtitle parsing during extraction (before the sample queue) or during decoding (after the sample queue).

This means in a later change we can still use some of the info for CBR
files, even if we want to ignore the imprecise table of contents and
seek based on a constant bitrate assumption instead.

An audio file can only play sound between two PCM samples (the 'start'
and 'end' of section of a wave form). Therefore when calculating
duration from a count of PCM samples we need to subtract one first (the
'end' sample which has no duration of its own).
This only changes durations by one PCM sample (21us - 22us for 44.1kHz sample
rate).
PiperOrigin-RevId: 596990306
The extractor knows the PCM encoding of the losslessly
encoded data in the samples and should set it in the
Format to allow downstream components to use this information.

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.

This file is CBR encoded with LAME, so it has an `Info` header (the CBR
equivalent to `Xing`).
A follow-up change will use this file in `Mp3ExtractorTest`.

`Cea608Parser` and `Cea708Parser` don't currently work correctly on
their own without the re-ordering of input buffers implemented in
`CeaDecoder`, and it's not clear how we can properly do this re-ordering
during extraction. This change ensures that if 'parse subtitles
during extraction' is enabled, CEA-6/708 subs will be passed through
without transcoding and can then be decoded during rendering by
`Cea6/708Decoder`.
PiperOrigin-RevId: 595658628
Invalid frames have no impact on ExoPlayer ability to play the media and should not fail on errors.
Some tools can add 100Mb images in the tags that will trigger recoverable OOM with this fix.
The `Cea608DecoderTest` added here fails if re-ordering is removed from
`CeaDecoder`.
The `Cea608ParserTest` is added with `@Ignore` because there's currently
no re-ordering support in this part of the subtitle handling pipeline
(partly because there's no concept of 'current playback time', meaning
it's hard to know **when** to re-order).

This more closely matches the intended, documented behaviour of this
method. The previous implementation was incorrectly checking
`sampleDataEnd + newSampleSize`, but it's more correct to compare
`existingSampleDataLength + newSampleSize`, in order to handle the
case of non-zero `sampleDataStart`. We've already checked above whether
`newSampleSize` fits after `sampleDataEnd` without growing or
reshuffling the array, so no need to basically repeat that check.
In the case of handling one sample at a time, the previous
implementation resulted in `sampleData` growing by `sampleSize`
**every time** the pointers reached the end. With the new check for
`sampleDataStart == sampleDataEnd`, this is avoided by always writing
each new sample at the start of the array (because the previous sample
has already been consumed), meaning `sampleData` remains equal to
`sampleSize` without growing.

The timestamp adjuster also estimates the number of wraparounds
of the 90Khz TS timestamp. It does that by assuming that a new
timestamp is always close to the previous one (in either direction).
This logic doesn't always work for duration estimates because the
timestamp at the end of the media is not close to the one at the
beginning and it may also never be less than the one at the beginning.
This can be fixed by introducing a new estimation model that assumes
the new timestamp is strictly greater than the previous one without
making the assumption that it has to be close to it.

Vertical and horizontal tile counts inside Format used by ImageRenderer
used to be required to equal 1 and were set to 1 regardless of what
the manifest said.
This change removes the above requirement and sets the tile counts to
the values from the manifest.

The MP4 data in JPEG motion photos can contain multiple `video/hevc` tracks, but only the first is at a playable frame rate while the others are low-fps, high-res tracks designed for specific use-cases (not direct video playback).
ExoPlayer currently selects the unplayable track by default, because it
has a higher resolution. This change introduces a flag to
`Mp4Extractor` that results in the first video track being marked as
`ROLE_FLAG_MAIN`, and all subsequent video tracks `ROLE_FLAG_ALTERNATE`
- this then results in the playable lower-res track being selected by
default.
