This is equivalent to the existing `scaleLargeTimestamp` method with the
following changes/improvements:
* No longer specific to timestamps (there was nothing inherently
time-specific about the logic in `scaleLargeTimestamp`, but the name
and docs suggested it shouldn't be used for non-timestamp use-cases).
* Additional 'perfect division' checks between `value` and `divisor`.
* The caller can now provide a `RoundingMode`.
* Robust against `multiplier == 0`.
* Some extra branches before falling through to (potentially lossy)
floating-point math, including trying to simplify the fraction with
greatest common divisor to reduce the chance of overflowing `long`.
This was discussed during review of 6e91f0d4c5
This change also includes some golden test file updates - these
represent a bug fix where floating-point maths had previously resulted
in a timestamp being incorrectly rounded down to the previous
microsecond. These changes are due to the 'some more branches' mentioned
above.

Modifying dumping to not required "released" to be called.
Track index is an arbitrary value based on the order of addTrack calls.
Samples are dumped by track (rather than as soon as they are written),
so it's preferable to use a value that provides more context.
By using the track type as a key, dump files will be more deterministic
and will have more similarities when branched.

This change makes capturing components in CapturingRenderersFactory
to dump data only they have previously captured any. This is so we can
extend the CapturingRenderersFactory with more renderers that do not
capture data in pre-existing tests and we don't have to change the
golden files.

also improves tests to hash bitmap now that we know the bitmaps are decoded in roboelectic tests,
as well as some minor fixes in the DefaultImageDecoder

Implement VideoCompositor support of:
* Different input and output sizes
* CompositorSettings, to customize output size based on input texture sizes
* OverlaySettings, to place an input frame in an arbitrary position on
the output frame.
Also, refactor Overlay's matrix logic to make it more reusable between
Compositor and Overlays

This file decompresses to 3024*4032*4 bytes ~= 48
MB, which leads to OOM errors on some devices.
Use a lower resolution test image for tests, to
still test a portrait image but without hitting
OOM errors.

In addition to this being how Alpha should be handled, tests do fail under
API 29 without this CL. Unfortunately while these tests do fail under API 29
without this CL, we currently only run this test on API 33 emulators, so we
didn't catch this failure earlier (until compositor tests on mh failed on all
devices under API 29 and succeeded on all at or over 29).

This test uses an existing CBR test asset, and shows that (as expected)
`isSeekable = true` even in the `unknown_length` dump file.
PiperOrigin-RevId: 557455364
This effect can scale Alpha values.
This is needed for testing Compositor, and coincidentally was requested
by a partner in the past. This also will generally be more useful in
full multi-asset, where we may want to have one input have different alpha
values than another
Also, update fragment_shader_copy_es2.glsl to not throw away alpha values.
This means ThumbnailStripShaderProgram (the only place this glsl is used) will
consider input alpha and output alpha appropriately

To ensure that for each output bitmap from the compostor, the right input
timestamps were used.
Only applied on a subset of tests to avoid needing to upload+maintain
too many files/size in the test binary, especially when it would test
duplicate behavior

The test file decompresses to about 48 MB, which can cause an
`OutOfMemoryError` on lower end devices.
Also, a test appears to apply a rotation to this bitmap without downscaling
first, leading to exceeding a maximum texture width/height of 4096 on some
devices.
Replace the test file with one that has a quarter of the original's
width/height so that these tests can pass reliably even on lower end
devices.

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.
This is the same change as 8655429af7, just on the second call site
of readDiscontinuity. The tests didn't cover this case yet because
they never queued more than 2 items in a playlist.
PiperOrigin-RevId: 553485244
After this change, every queued bitmap is treated as an individual input stream
(like a new MediaItems).
This change merges the FrameDropTest and FrameDropPixelTest into one (while maintaining all the test cases)
- This is accomplished by generating bitmaps with timestamps on it in FrameDropTest and compare them with goldens (one may call this a pixel test, please lmk if you want this to be renamed)
- The most part of the change comes from DefaultVideoFrameProcessorVideoFrameRenderingTest. The overall working is
- We bypass the input manager
- The TestFrameGenerator generates frames based on timestamps. In this case, we generate frames with timestamps on it
- The generated frame is sent to texture output and in turn saved to bitmaps
- We then compare the generated bitmap with the goldens

When generating silence for AudioProcessingPipeline, audio never
queued EOS downstream.
Linked to this, when silence followed an item with audio, the silence
was added to SilentAudioGenerator before the mediaItem reconfiguration
occurred. If the silence had effects, the APP would be flushed after
silence queued EOS, resetting APP.isEnded back to false, so AudioGraph
never ended.
Regression tests reproduce failure without fix, but pass with it.

Instead of `text/x-exoplayer-cues`, we will use `application/x-media3-cues`.
The prefix should be `application` not `text` since the encoded form is arbitrary bytes, not necessarily text. The name should not reference `exoplayer`, since the Media3 Extractors (which are not part of `exoplayer`) produce this format.
PiperOrigin-RevId: 550181852
Alters the OverlayShaderProgram implementation to support rotations, however we need to apply the transformations separately in order for them to work as expected so the matrix is removed from the interface in favour of explicit methods.
Adds a rotation test to ensure this ability doesn't regress

It is not part of the `SubtitleParser` interface's promise to give events for all changes to do with `Cue` objects. So while in the past, we would have `endTimeUs` of one Cue event being the `startTimeUs` of the next one, now we have that encoded in `durationUs` and can skip event with empty `Cues`.

This is no longer flaky because WebVTT subtitles are decoded on the
loading thread (enabled in this test with
`defaultExractorsFactory.setTextTrackTranscodingEnabled(true)` - and
supported for WebVTT since f0f24aa0d4).
PiperOrigin-RevId: 549594291
The end-to-end test output for the overlapping SRT and SSA subtitles
is currently incorrect. They will be fixed in a future change that
updates `TextRenderer` to support this overlap.
The 'extra' samples visible in the extractor test output files are
'empty cue list' samples produced by `SsaParser`. They will go away
when this implementation is updated to remove this behaviour and rely
on `CuesWithTiming.durationUs` instead (the 'empty list' behaviour is
not required by the `SubtitleParser` interface).
