Being able to see the output of the GL pipeline is useful for debugging. For
example, when we previously saw flakiness it would have been useful to be able
to tell quickly whether the output looked wrong without needing to run a
transformation to the end then inspect the output file, and when working on
support for HDR editing it's useful to be able to do manual testing on devices
that don't support HDR encoding (but do support decoding/processing it with
GL).

Also change the progress indicator to be linear as this looks better in the
demo app when shown next to the debug preview.

This is a no-op change that updates supportsFormat to use the
decoder list before it's reordered by format support. Instead,
supportsFormat iterates through the decoders listed in their
original priority order as specified by the MediaCodecSelector.
The end result is identical.

This is necessary groundwork for a subsequent change that will
indicate in Capabilities whether the decoder that suppports the
format is the primary one as specified by the MediaCodecSelector
(i.e., the one at index=0 in the lists that are now used).

The color set via textAppearance is overridden by any non-null
textColor set directly on the style. We always want the specific
properties the textAppearance specifies, so set them directly to
prevent them from being overridden.

Configure MediaCodec in API 32+ to always output 99 channels
so that we use the audio is spatialized, if the platform can apply
spatialization to it.

In a follow-up change, the output channel count will be set based on the
device's spatialization capabilities.

`DefaultAudioSink` already has 3 telescoping
constructors and an other one would be have been
needed to add a buffer size tuning option.

The existing code creates an imbalance between `inputBufferCount` and
`droppedBufferCount` by adding 'dropped source buffers' to
`droppedBufferCount` but not to `inputBufferCount`. This results in
assertion failures in `DashTestRunner`.

It's been observed that some devices fail when releasing a secure codec
attached to a surface and immediately trying to create a new codec
(secure or insecure) attached to the same surface. This change catches
all exceptions thrown during codec creation, sleeps for a short time,
and then retries the codec creation. This is observed to fix the problem
(we believe this is because it allows enough time for some background
part of the previous codec release operation to complete).

This change should have no effect on the control flow when codec
creation succeeds first time. It will introduce a slight delay when
creating the preferred codec fails (while we sleep and retry), which
will either delay propagating a permanent error or attempting to
initialize a fallback decoder. We can't avoid the extra delay to
instantiating the fallback decoder because we can't know whether we
expect the second attempt to create the preferred decoder to succeed or
fail. The benefit to always retrying the preferred decoder creation
(fixing playback failures) outweighs the unfortunate additional delay
to instantiating fallback decoders.

Also, add 144p as an acceptable output resolution, to allow for
a more obvious resolution difference when running the demo.

The new field matches the platform's
AudioAttributes.getSpatializationBehavior() API added in Sv2. At the
moment, the platform API is called via reflection, until Sv2 is released
and the compile SDK target can be increased to 32.

* Remove casting getInstance and getCallback methods and just
  use member variables that have the more specific types. I
  didn't manage to get rid of casting completely; there are
  still one-off casts during construction. We should look at
  removing those in the future, but it's not completely
  trivial due to the way the Impl classes back-reference
  their wrapping classes.
* Move all callback invocations inside the Impl classes for
  consistency, and properly encapsulate the callbacks there.
  Sticking with the "OnHandler" naming convention for these
  methods, but we should probably tweak that in a subsequent
  change.
* Encapsulate MediaItemFiller in MediaSessionImpl.
* Some misc cleanup (e.g., converting anonymous inner classes
  to lambdas where possible).

When calling Android's Log class directly, there's a LongLogTag
lint check that detects tags over the 23 char limit, however it
cannot detect long log tags in ExoPlayer due to the way that we
log via our own Log class. This commit adds @Size annotations to
enforce the same rule.

On the Sony Android TV device where this was originally reproducible on
Android L, on Android N there is an E-AC3 decoder listed which handles
the stream correctly. The workaround is harmless anyway but adding the
API version restriction means it will be obvious it can be removed once
we bump our min API to 24 or above in the future.

This is required for correct subscription notifications, as per the

in general, rather than re-implementing the functionality in the stub.

Using chunkless preparation greatly improves start up time if the master
playlist declares CODECS for the renditions. Hence, we turn this on
by default as it benefits most well-defined HLS master playlists.

The only known reason why developers may want to turn this feature off is
when the renditions contain muxed closed-caption tracks that are not
declared in the master playlist. So this change also updates the documentation
and RELEASENOTES to point out this caveat.

Increase timeout for dequeueing a frame from the codec to reduce
flakiness. At a timeout of 2 seconds there was a 2/1000 flake rate and
at 3 seconds 0/1000. Set the timeout to 5 seconds to give plenty of
leeway.

Hardware audio decoders aren't really a thing, particularly on older
devices. SOC vendors do sometimes provide their own software decoders
though. Hence we update the approximation to assume that audio
decoders on older devices are software.

We do not rely on the payload type to determine the sample MIME type, we depend
on the SDP message, so it's worthless checking the payload type.

After removing the line, a server can use payload type 35 (an unassigned
payload type) for H264; while normally H264 requires payload type >= 96).

Previously, transformation_matrix was incorrectly applied to
texture sampling coordinates, which led to transformations
seemingly moving in the opposite position, and an undesirable
GL_CLAMP_TO_EDGE behavior when sampling outside the edge of
the texture.

Allowing duplicate groups caused some other code working with the
array to use reference equality comparison. This is error-prone,
easily forgotten (e.g. when using the TrackGroups in a map) and
causes bugs when TrackGroups are serialized to disk or to another
process.

All TrackGroups created by ExoPlayer are already unique and custom
code creating TrackGroupArrays with identical groups can easily
distringuish them by adding an id to each group.

This allows to give TrackGroups an identifier. The underlying goal is
to provide a way to make otherwise identical TrackGroups
distinguishable.

Allows a transformation matrix to be input into Transformer,
to apply vertex transformations like cropping, rotation,
and other transformations built into android.graphics.Matrix.

Not building out into a VertexTransformation class yet, as
that class structure wouldn't make sense until we can modify
resolution, per TODOs.
