The serializable form is used when we need to serialize the result into
bytes in the sample queue. The binder-based (ultimately
filedescriptor-based) form is used for
session/controller IPC, in order to avoid sending the bitmap bytes over
the IPC.

This image has two video tracks in the MP4 data, one is a 'real' video
which we want to play by default, and the other is a low-fps video track
which isn't intended to be directly played, it's encoded in HEVC for
compression and decoding efficiency.
This test demonstrates ExoPlayer's current behaviour default extraction
and playback, which results in selecting the high-res, low-fps track
(actually single sample in this example), instead of playing the actual
video.

As Opus decoders skip some bytes prior to playback during a seek, the renderer for bypass playback should send samples to the decoder even if they would be decode-only. However, the renderer should not send samples with time preceding that range. This change adds that constraint.

Both the extension OPUS decoder and the OMX/C2 MediaCodec
implementations for OPUS and VORBIS decode into the channel
layout defined by VORBIS. See
https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-140001.2.3
While this is technically correct for a stand-alone OPUS or VORBIS
decoder, it doesn't match the channel layout expected by Android.
See https://developer.android.com/reference/android/media/AudioFormat#channelMask
The fix is to apply the channel mapping after decoding if needed.
Also add e2e tests with audio dumps for the extension renderer,
including a new 5.1 channel test file.

Serializing bitmap cues is currently broken, but this test is
incorrectly passing. This change makes two changes to introduce the same
failure (both changes are necessary, each one alone still passes):
1. Move from Robolectric to an instrumentation test.
2. Trigger the `Bitmap` to be serialized using a file descriptor, either
by calling `Bitmap.asShared` in the test when constructing the `Cue`,
or constructing the `Bitmap` from a 'real' image byte array instead a
1x1 token image.

MIME types are case-insensitive, but none of the many existing
comparisons across our code base take this into account. The
code can be made more robust by normalizing all MIME types at the
moment they are first set into a class/builder and adding toLowerCase
as part of the normalization.
Most concretely, this fixes an issue with playing HLS streams via
the IMA SDK where the stream MIME type is indicated with all lower
case "application/x-mpegurl", which failed the MIME type comparison
in DefaultMediaSourceFactory.

* Rename method f(n) to a more helpful name.
* Move the private inner class to the bottom.
* Move public fields before private fields but below the static field.
* Make `private ParsableByteArray data` final.
* Make sure `parseSequenceHeader` can only be called once.
BundleableUtil is the only class that really depends on the type
inheritence from Bundleable. However, it only needs this as a way
to define Function<T, Bundle> and Function<Bundle, T>, which could
just be passed in as parameters as it's already done for some of
these methods.
Also rename the class to BundleCollectionUtil accordingly.

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.

All production and test callers of the non-incremental methods are
already migrated, so we can remove them in this change too.

If the `Subtitle` has 'active' cues at `OutputOptions.startTimeUs`, this
change ensures these are emitted in a `CuesWithTiming` with
`CuesWithTiming.startTimeUs = OutputOptions.startTimeUs`. If
`OutputOptions.outputAllCues` is also set, then another `CuesWithTiming`
is emitted at the end that covers the 'first part' of the active cues,
and ends at `OutputOptions.startTimeUs`.
As well as adding some more tests to `LegacySubtitleUtilWebvttTest`,
this change also adds more tests for `TtmlParser` handling of
`OutputOptions`, which transitively tests the behaviour of
`LegacySubtitleUtil`.
#minor-release

All the production code is already calling these new incremental
methods, migrating the tests allows us to remove the old
`List`-returning methods in a follow-up change.

Looping through all MIME types is a bit hacky, but seems like a nice way
to check "all" MIME types (or at least more than a random selection).

This currently only applies to subtitles muxed into mp4 segments, and
not standalone text files linked directly from the manifest.

This gives access to the replacement behavior for a particular subtitle
format without needing to instantiate a `SubtitleParser`.

This is more correct, though in reality all text-based subtitles handled
by `SubtitleExtractor` are implemented with MERGE behavior in media3.

The flag is no longer used by our components and only set and checked
in a few places to guarantee compatiblity with existing renderers and
decoders that still use it.
The flag will be removed in the future due to its design limitations.

The existing `Subtitle` handling code is left intact to support the
legacy post-`SampleQueue` decoding path for now.
This also includes full support for merging overlapping `CuesWithTiming`
instances, which explains the test dump file changes, and which should
resolve the following issues (if used with the
decoder-before-`SampleQueue` subtitle logic added in
5d453fcf37):
* Issue: google/ExoPlayer#10295
* Issue: google/ExoPlayer#4794
It should also help resolve Issue: androidx/media#288, but that will also require
some changes in the DASH module to enable pre-`SampleQueue` subtitle
parsing (which should happen soon).

In most cases this is more useful than `durationUs`.
We will keep `durationUs`, and the constructor will continue to take
`startTimeUs` and `durationUs`, to allow for use-cases where we don't
know the start time but still want to indicate a duration (this will be
used to implement CEA-608 timeout).
#minor-release
PiperOrigin-RevId: 570944449
This gets rid of the reliance on the decode only flag that is still
set on input buffers to the decoder if they are less than the start
time.
We still need to set and check the decode-only flag in SimpleDecoder
to ensure compatbility with custom decoders that use the flag while
it's not fully removed.
