Before this CL, externalShaderProgramInputCapacity was not reset when
the external shader program was reset (which occurs when the
InputSwitcher switches to an input with a different ColorInfo). This is
due to a regression introduced in bef3d518d2.

PQ and HLG have different luminance ranges (max 10k nits and max 1k nits resp). In GL, colors work in a normalised 0 to 1 scale, so for PQ content, 1=10k nits and and for HLG content, 1=1k nits.
This cl scales and normalises PQ content appropriately so that all HDR content works in the HLG luminance range. This fixes two things
1. Conversions between HLG and PQ are "fixed" (before the output colors looked too bright or too dark depending on which way you are converting)
2. color-altering effects will be able to work consistently across HLG and PQ content
1 is tested in this cl. 2 will be tested when ultra HDR overlays are implemented, both cases have been manually tested to ensure the output looks correct on a screen.

Fragment shaders in OpenGL ES shader language aren't guaranteed
to support highp, required to correctly represent pixel coordinates
inside large images (e.g. 1920x1080).
This change moves coordinate mirroring for images out of fragment shader.

If MediaCodec allocates passes an image buffer with a cropped region,
SurfaceTexture.getTransformMatrix will cut off 2 pixels from each dimensions.
The resulting videos will appear a little stretched.
This patch inspects the SurfaceTexture transform matrix, and guesses what the
unscaled transform matrix should be.

Gainmaps don't currently have an equals override, only reference equality is checked by Objects.equals(gainmap1, gainmap2). Create an equals method for gainmaps with the fields we care about to ensure we don't incur false positives in our equality checks.

This annotation is only needed on public classes.
This change also removes the `/* package */` comment from some `public`
classes.

After this CL, DVFP waits for flushing until all frames registered previously
arrives.
Previously, ETM records the difference between the number of registered frames,
and the number of frames arrivd on the SurfaceTexture, when flushing. (Note
that ETM is flushed the last in the chain, as flushing is done backwards from
FinalShaderProgramWrapper). ETM then waits until the number of frames arrive
after flush.
The normal flow is, MediaCodecVideoRenderer (MCVR) registers a new decoded
frame, in `processOutputBuffer()` to DVFP, MCVR call `codec.releaseOutputBuffer()`
to have MediaCodec render the frame, and then the frame arrives in DVFP's ETM.
However there might be a discrepancy. When registering the frame, ETM records
the frame on the calling thread, ~instantly. Later when the rendered frame
arrive, ETM records a frame is available on the task executor thread (or
commonly known as the GL thread). More specifically, when a frame arrives
in `onFrameAvailableListener`, ETM posts all subsequent processing to
the task executor. When seeking, the task executor is flushed as the first
step. It might be a frame that has already arrived on ETM, and the processing
of such frame has already been queued into the task executor; only to be
flushed as a result of flushing the task executor. If this happens, the frame
is considered to be never have arrived. This causes a freeze on the app,
because ETM'll wait until this frame arrives to declare flushing has completed.

The second stage of the changes remove the conversion to linear colors in the SDR effects pipeline by default.
also resolves Issue: androidx/media#1050
PiperOrigin-RevId: 630108296
Part of a two stage change to remove the conversion to linear colors in the SDR effects pipeline by default. Changes the boolean to an intdef, introducing a third option that gets all sdr input into the same colorspace.
This is a planned API breaking change, but this change should not change the behavior of the pipeline.

also makes the setter more flexible by ignoring the value of the setter when the output is hdr rather than throwing (since all HDR content must be have a linear color space)

We currently check certain properties about inputColorInfo twice: once in checkColors in the DVFP and once when creating the samplers in the defaultshaderprogam. The inputcolorinfo shouldn't change between these two components so removing the checks in the shader program to have one source of truth for inputColorInfo checks, which will make the code simpler when it comes to adding to color-related features (like the ones related to removing de-gamma-ing)
