This happens when using `ExoPlayer.setVideoEffects()`.
This CL also fixes the first frame not rendered problem, originally solved in
7e65cce967, but rolled back in 5056dfaa2b because the solution introduces
the flash that is observed in b/292111083.
Before media3 1.1 release, the output size of `VideoFrameProcessor` is not
reported to the app. This was changed later after introducing
`CompositingVideoSinkProvider`, where the video size after processing **is**
reported to the app. After this CL, the size is again, not reported.

7e65cce967 introduced a regression on ExoPlayer.setVideoEffects()
where there is flash on the screen after the first few frames are shown.
Before 7e65cce967, the first frames of the content are missed, until
MediaCodecVideoRenderer sends the onVideoSizeChanged() callback. The
first frame is processed but not shown, the onVideoSizeChanged() is
triggered and the renderer receives a video output resolution message as
a response from the UI.
7e65cce967 fixed the missed first frames by setting a surface on the
CompositingVideoSinkProvider before the provider is initialized, and as
as result:
- the first frames are rendered
- the MediaCodecVideoRenderer sends the the onVideoSizeChanged() after
frames are shown
- the UI sends a video output resolution change
- the MediaCodecVideoRenderer updates the CompositingVideoSinkProvider
which causes the flash.
The underlying problem is with onVideoSizeChanged() not being
triggered early enough, before the first frame is shown.
Because the flashing is a regression, this commit is reverting
7e65cce967 but keeps the test that was added as ignored, so that the
test is re-enabled as soon as we address the underlying issue.

Instead, for input videos, use the colorInfo provided by the extractor. Similarly, for input images, use sRGB, the only color currently in use.
Textures do still need the input ColorInfo provided though.
PiperOrigin-RevId: 592875967
Move `inputColorInfo` from `VideoFrameProcessor`'s `Factory.create` to `FrameInfo`,
input via `registerInputStream`.
Also, manually tested on exoplayer demo that setVideoEffects still works.

This is because currently
1. Player sets a surfaceView to render to
2. Player intializes the renderer
3. MCVR initializes the VideoSinkProvider, by extension VideoGraph
But when 1 happens, MCVR doesn't set the surfaceView on the VideoGraph because
it's not initialized. Consequently after VideoGraph is initialized, it doesn't
have a surface to render to, and thus dropping the first a few frames.
Also adds a test for first frame to verify the correct first frame is rendered.

Throws when calling flush when there's no active input, for example
before an input stream is registered or after all output streams have
ended.

Much simpler than ExternalTextureManager flushing, because
ExternalTextureManager complexity is due to decoder race condition behavior,
which we won't see for Bitmaps due to a more well-defined interface.
This is needed to test texture output flushing.

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.

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.

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.

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.

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
PiperOrigin-RevId: 551795770
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

Before this CL, the text with a scale span would wrap text, with because the scale wasn't taken into account when measuring the width of the overlay.

Frame buffers are focused, not current. EGL Contexts may be current but this
is a prerequisite for focusing a framebuffer, and this alone isn't
sufficient to make a bitmap.
Clear this up as it can make some complex tests harder to understand, if the
methods needed don't match up in naming.

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.

By passing this class where it's needed, implementations don't need to store it
in a field (reducing boilerplate) and it's clearer that it can't be unset when
needed.

To more accurately describe what they do, especially as Compositor will
starts to use more contexts or threads, and it's important to know what
needs to be reset/recreated/focused before what methods.

The existing NullableType has been deprecated 5 years ago and causes
crashes in Kotlin apps because Kotlin doesn't recognize this annotation
as a nullable type annotation.
While we can't align on a single @Nullable annotation yet, we can at
least replace this one by JSR305's @Nonnull(MAYBE) as it fulfils all
requirements, including full Kotlin compatiblity. To avoid the
cumbersome name, we can redefine it as our own @NullableType
annotation. (We can't use @Nullable to avoid name clashes with the main
@Nullable annotation from AndroidX)
