That said, only SDR is supported for now, so this will always throw if
HDR is input. This will also throw if different ColorInfo values are input
because color SDR mixing (ex. between sRGB and BT709) is not yet supported.

Instead of invoking "undefined behavior" may occur when a class is used
incorrectly, which is clear but not very helpful to callers, specify what Apps
or users of a class should do when issues occur.
Apply this to Compositor as well, where this otherwise might seem unclear.

Overlays may be overlaid over:
* In VideoFrameProcessor, videos or images (or texture input).
* In Compositor, other videos.
In Compositor, Overlays may consist of video, so it could be confusing
for videoFrameAnchor to contrast with overlayAnchor.
Also, rename overlayAnchor to overlayFrameAnchor, since it's modifying
the anchor in the overlay's frame, so this name seems slightly more precise.
PiperOrigin-RevId: 562004292
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
PiperOrigin-RevId: 561931854
Split this logic out from `OverlayShaderProgram`, to share logic like
this with `VideoCompositor`.
Also, remove the unused `context` parameter from `OverlayShaderProgram`
`VideoCompositor` will reuse `OverlayMatrixProvider`'s storing of the matrices,
though it may generate the matrices differently, since `OverlayShaderProgram`
applies this in the fragment shader, whereas `VideoCompositor` applies this in the
vertex shader.

The actual logic scales the alpha, instead of setting it, so rename
this to what it does.
We would also prefer alpha to be scaled here, to not lose alpha information
(for example for PNGs with transparent regions).

The first call to method `registerInputStream` doesn't block.
Later successive calls to the method blocks until the previous register call
finishes.

Replace Queue<Long> with LongArrayQueue which provides queue semantics
for long primitives. LongArrayQueue is forked from IntArrayQueue which
in turn was forked from Androidx CircularIntArray.
IntArrayQueue is deleted and we now use CircularIntArray directly from
Androidx Collection.

In case BaseShaderProgram implementations have an expensive
configure() call, we can only call configure() when absolutely necessary,
aka when the input size changes.
To reduce scope, this doesn't reduce the amount of
configure() calls that may be made outside this class, in
DefaultFrameDroppingShaderProgram and
FinalShaderProgramWrapper.

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).

`BlankFrameProducer` was originally internal to
`DefaultVideoFrameProcessorVideoFrameRenderingTest`. We later copied it in
c221958889. This CL converges the usages.

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

This adds an effect to change the speed of the video track. The speed
of the audio track can already be changed using a SonicAudioProcessor.

When implementing pause and resume, overlay appears as black frame on resume, suggesting the texture isn't being remade properly due to lack of proper deletion.

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.

This means we now require 2+ input frames per input, and compare the primary
stream timestamp with secondary stream timestamps in order to select the
correct output timestamp. We also must release frames and back-pressure as
soon as possible to avoid blocking upstream VFPs.
Also, improve signalling of VFP onReadyToAcceptInputFrame

This allows for custom implementations of this interface, like
a TestVideoCompositor or partner-implemented implementation

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

For each event, the timestamp and presentation time is logged. The trace can
then be dumped to a tsv file and easily imported in a spreadsheet.

signalEndOfInputStream is needed for when streams have different amounts of
frames, so that if the primary stream finishes after a secondary stream, it
can end without waiting indefinitely for the secondary stream's matching
timestamps.
onEnded mirrors this API on the output side, which will be necessary to
know when to call signalEndOfInput on downstream components (ex. on downstream)
VideoFrameProcessors

The VideoFrameProcessingTaskExecutor already handles wrapping
GlUtil.GlException errors into VideoFrameProcessingExceptions.
Therefore, stop wrapping this ourselves, so that errors are
attributed to the correct line number with less indirection.
