Opening the `DataSource` is one of the longer operations in the `Loader` sequence, as it requires a round trip to the origin server. This change allows all the potential `Loader` threads to perform this operation before one of them is forced to wait on shared TimestampAdjuster initialization.
Also, the initialization segment load will never produce media samples, so there is no need for it to wait for `TimestampAdjuster` initialization.
UnsupportedEglVersionException() is only used once, and seems a bit too
specific for Transformer. Also, it's possible for eglCreateContext to fail for
other reasons besides lack of support, so it wasn't always accurate when
thrown.
It is possible for devices not to support EGL version 2.0 though, per
https://source.android.com/devices/graphics/implement-opengl-es, which doesn't
specify the EGL version that must be supported.

tl;dr:
In the previous transformer, the transcoding flow is
- If a the GL's input surface (from decoder) does not have data, wait 10ms
(DO_SOME_WORK)
- Else, make the decoder render **ONE** frame to the GL's input surface
- Wait at least 10ms, until the frame's texture is available
- Then process the texture
The process is quite slow, so in the new version, we do:
- If a the GL's input surface (from decoder) does not have data, wait 10ms
(DO_SOME_WORK) **same**
- Else, make the decoder render **as many frames** to the GL's input surface
- Process **as many** available textures in this DO_SOME_WORK cycle

*** Original commit ***
Make audio track min buffer size configurable.
Move the code in its own class as DefaultAudioTrack
is getting very big. It also help for testability.
The new class is easily configurable and highly tested.
Manual test was used to catch any regression.

The input rotation is used to rotate the video during decoding, the
video is rotated so that it is in landscape orientation before encoding
and a rotation is added to the output format where necessary so that
the output video has the same orientation as the input.

Refactor GlUtil.java to be a bit more readable. Also, reorder, inline, and
rename a few things. Refactoring change only. No functional changes intended.

For DASH manifests, we merge min/max live latency values from various
sources and they may not be consistent with each other. To ensure we
use a sensible configuration in all cases, we can add more correctness
checks:
1. Limit the min/max values to fall into the available live window.
2. Ensure that maxLatency >= minLatency in all cases.

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.
PiperOrigin-RevId: 414703366
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.

The TrackSelection API returns two indexes, the index of the selected
track (`getSelectedIndex()`) and the index in the `TrackGroup`. The `HlsChunkSource`
and `HlsSampleStreamWrapper` should only work with the later.
Actually the `getSelectedIndex()`, current selected track index is really only useful on
the API to determine if there is a valid selection or not. The index is
really internal to `TrackSelection`
