This file is CBR encoded with LAME, so it has an `Info` header (the CBR
equivalent to `Xing`).
A follow-up change will use this file in `Mp3ExtractorTest`.

Mp4Muxer does not support out of order B-frames. Currently it
silently writes out of order B-frames, producing an invalid file (with
negative sample durations).
Although `Mp4Extractor` is somehow able to process this invalid file and
`Exoplayer` is able to play it but that is unexpected.
The `sample.mp4` test file contains B frames. Other test files does not
contain `H264 video + AAC audio` format hence created a new test file by
running `sample.mp4` via `Transformer` after applying some effects.

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.

Replace the event for notifying fallback to cover codec initialization in
general (but keeping the list of errors).
Add a flag to control whether to try non-primary codecs, with the same
documentation as the similar flag in ExoPlayer's renderer.
Make the class final as it shouldn't be necessary to subclass it.

Checking the output format's mime type may skip tests more often than we'd like,
because we may desire using a lower-spec output mimetype than what's passed in, if
based on the input's HDR mimetype value.
Therefore, update this output format to null, for tone-mapping tests

Move `inputColorInfo` from `VideoFrameProcessor`'s `Factory.create` to `FrameInfo`,
input via `registerInputStream`.
Also, manually tested on exoplayer demo that setVideoEffects still works.

Despite GL 3.0 not being required on API 29+, it is experimentally
determined to always be supported on our testing devices, on API 29+.
That said, still fall back to OpenGL 2.0 if 3.0 is not supported,
just in case.

Also adds an alternate way to configure the AudioGraph.
Apps should no longer need to ensure that inputs have the same sample
rate.

Added a new ABANDONED option so one can tell the difference between when the optimization has been requested but not applied vs not requested at all. also changed the ordering do better represent the hierarchy of failure modes

This helped me debug which bitmap was actually failing. Otherwise, you need to clear all bitmaps on the device relating to this test, then adb pull all bitmaps and see the last uploaded one to see, which is much more confusing.

* @Before and @After usage. [1].
* static fields before non-static. [2].
@Before method should typically be paired with an @After method,
focused on ensuring that the component is released regardless of what
the test does.
In tests, inlining final class variables is preferrable [1]. In general
things like the file path should be part of the test (the @Rule means
we don't need before/after) if only used once.
Statically importing values and using them directly is preferable to
having a variable declared as non-final that's effectively final,
because from a readability perspective someone can see (the caps) that
the value is final static and immutable, so doesn't have to check if
it's changed/reassigned.

The issue that motivated adding this (frames unexpectedly being dropped by the
decoder) has been addressed, so we can turn off the logging to reduce
unnecessary allocations during transformation. We can easily turn on debug
logging in future as needed by setting `DebugTraceUtil.DEBUG = true`.
Also avoid allocations for string building at logging call sites by passing a
format string for extra info. Formatting the string now only happens when
debugging is turned on.
Tested manually by running transformations in the new state (DEBUG = false) and
with debugging turned on.

The decoder and encoder won't accept high values for frame rate, so avoid
setting the key when configuring the decoder, and set a default value for the
encoder (where the key is required).
Also skip SSIM calculation for 4k, where the device lacks concurrent decoding
support.

Using `Integer.MAX_VALUE` risks causing arithmetic overflow in the codec
implementation.

These usages have no need for the double ended input functionality. All
other usages across media3 are ConcurrentLinkedQueue.

Composition and EditedMediaItemSequence don't allow empty lists in their main
constructors, so shouldn't the vararg API. This is more inline with Effective
Java item 53.

When transmuxing, the `EncodedSampleExporter` maintains a queue of input
buffers that get filled with encoded data by the asset loader. The number of
buffers was limited to avoid using more and more memory if producer (asset
loader) gets far ahead of the consumer (exporter).
Previously this limit was fixed at 10 buffers, but increasing the number of
buffers can make some transmux operations much faster. Allow allocating between
a min and max number of buffers, and also set a target allocation size beyond
which new buffers can't be allocated. This allows audio formats which require
many small buffers to be processed more quickly, while preventing allocating
too much memory for hypothetical very high bitrate formats.
'Remove video' edits on local videos in particular get much faster, because
audio buffers are very short and there are lots of them. With a sample 10
minute video, a 'remove video' edit took 2 seconds (36 seconds before this
change). With a sample 1 minute removing video took 0.25 seconds after this
change (2.5 seconds before).
The speed improvement is smaller for other types of edits that retain the video
track. Transmuxing a 10 minute video retaining the video track took 26 seconds
(40 seconds before).
