AudioTrack.setOffloadEndOfStream should be called after a track
has been buffered. Additionally, the AudioTrack must be playing.
It has been observed that for very short media (<1s), the AudioTrack
might not have started immediately after the read that buffered
the audio.
In such a situation, calling AudioTrack.setOffloadEndOfStream throws
and playback fails.
Avoid this failure by checking that the AudioTrack is playing before
calling setOffloadEndOfStream.
This means that very short gapless media will not be gapless, this was
deemed acceptable given that such very short media should be very rare
in offload.

Remove `@Nullable` from `MediaSource.Factory` setters
The null-behaviour of these methods creates a minimization footgun,
because **any** call to these setters will prevent R8 from removing
the default implementation (even if it's never used by the app) - this
is because R8 can't tell the default implementation is only used if the
parameter is `null`.

Put cloud storage samples at the top to avoid having a sample at the top of the list where we don't control the server.
Also update labels not to mention progressive container type, as it's irrelevant for Transformer, which always transmuxes even if it doesn't transcode.

This detection relies on an unsupported workaround and may trigger
permission warnings in tools analyzing permission usage although
no permission is needed or requested by app code.
Given the majority of 5G-NSA playbacks are on API 31+ by now,
we can remove this path to avoid the permission confusion and the
unsupported detection workaround.

The debug surface view's output surface can become invalid during a transformation due to the parent activity pausing, for example. This can currently cause a crash when backing out of the `TransformerActivity` in the demo because the surface can be destroyed before the transformer has fully canceled.
Also clarify naming of the outputSurface and inline the private method that created `EGLSurface`s (it was shorter after removing the debug preview).

This causes a bug where the forwarded selections are no longer
assumed equal and the child MediaPeriods will think they need
to reset streams even though the selection stayed the same.

The old reference was just for prototyping HDR. The new reference is for planned work to use the correct formats for input and output for HDR editing in GL.

The MMWAVE constant was deprecated in favour of a new constant
with a better name. Thus, we need to check for both constants now.

This is an individual language (ISO 639-3) part of the Arabic

When using a MatrixTransformationFrameProcessor per transformation
matrix, each frame processor's shader applies the matrix to the
vertices and clips the result to the NDC range when drawing the
output frame.
This change combines consecutive MatrixTransformations into a single
MatrixTransformationFrameProcessor by multiplying the individual
matrices while updating and clipping the visible polygon after
each matrix and mapping the resulting visible polygon back to the
input space so that its vertices and the combined transformation
matrix can be used in the shader.

Network type detection on these API levels couldn't be tested
yet because of a missing Robolectric feature. This was fixed by
the recent Robolectric upgrade and the restrictions can be removed.
This also requires to replicate the platform hack we rely on on
these API levels.

This listener replaces
FrameProcessorChain#getAndRethrowBackgroundExceptions.
The listener uses a new exception type FrameProcessingException
separate from TransformationException as the frame processing
components will be made reusable outside of transformer soon.

This constant is used for https://docs.gl/es2/glVertexAttribPointer
which takes the number of components per generic vertex attribute
(meaning the size of the individual coordinate vectors here) not the
number of attributes (the number of vertices that the old constant
name referred to).

Before this change, we list the formats for which we don't
want transcoding. This change disables transcoding altogether.
This was tested by checking that transcoding takes place on a
short camera recording only when the added flag is not present
(and AndroidManifest does not declare support for HEVC).

We won't try to provide/rethrow helpful error messages that are already
provided by GL, as this sort of task would expand into writing a GL verifier.
A Gl verifier is unnecessarily complex for minimal payoff, especially as Apps
expected to read GL error messages would mostly be those writing custom
GlFrameProcessors, who should be already be familiar with reading GL error
messages anyways.

Relates to https://github.com/square/okhttp/issues/3146. This was from https://github.com/androidx/media/pull/71.
There is a draft PR https://github.com/square/okhttp/pull/7185/files which documents OkHttp's ideal handling of cancellation including interrupts.
But a few key points
1) This is a target state, and OkHttp does not currently handle interrupts correctly. In the past this has been identified, and the advice is to avoid interrupts on Http threads, see discussion on https://github.com/square/okhttp/issues/1902. Also an attempt at a fix here https://github.com/square/okhttp/pull/7023 which wasn't in a form to land.
2) Even with this fixed, it is likely to never be optimal, because of OkHttp sharing a socket connection for multiple inflight requests.
From https://github.com/square/okhttp/pull/7185
```
Thread.interrupt() is Clumsy
----------------------------
`Thread.interrupt()` is Java's built-in mechanism to cancel an in-flight `Thread`, regardless of
what work it's currently performing.
We recommend against using `Thread.interrupt()` with OkHttp because it may disrupt shared resources
including HTTP/2 connections and cache files. In particular, calling `Thread.interrupt()` may cause
unrelated threads' call to fail with an `IOException`.
```
This PR leaves the Loader/DataSource thread parked on a countdown latch, while this may seem wasteful and an additional context switch. However in practice the response isn't returned until the Http2Connection and Http2Reader have a response from the server and these means effectively parking in a `wait()` statement here 9e039e9412/okhttp/src/jvmMain/kotlin/okhttp3/internal/http2/Http2Stream.kt (L140)
