The current setup with distinct, private `keyForField` implementations,
leaves open the (theoretical) possibility of a clash in the `Bundle`
keys used by the superclass and subclass. This change brings
consistency with our only other extensible `Bundleable` type
(`PlaybackException`).

We generally nest the `Builder` for `Foo` inside `Foo`. In this case,
there's already a `DefaultTrackSelector.Parameters.Builder` type visible
to a developer, it just happens to be the 'common'
`TrackSelectorParameters.Builder`, so using it is a bit weird. For
example this code snippet doesn't compile because
`DefaultTrackSelector.Parameters.Builder#build()` returns
`TrackSelectionParameters`. This CL fixes that problem and the code
snippet now compiles.

```java
DefaultTrackSelector.Parameters params =
   new DefaultTrackSelector.Parameters.Builder(context).build()
```

Implementations of this interface will be able to drop or add frames,
change timestamps, accept multiple input frames before producing
output, and process frames on their own background thread.

A default implementation of this interface will be added to SingleFrameGlTextureProcessor in a follow-up.

This is done by removing the `@FieldNumber` IntDef completely. It's not
really adding much value anyway, because it's `open` so there's no real
enforcement to prevent passing 'incorrect' values.

This internal listener avoids wrapping the TransformationExceptions
in PlaybackExceptions that are handled via the Player.Listener and
is also used for FrameProcessingExceptions which already avoided
the PlaybackException layer previously.

This listener will also be useful in follow-ups for encoder-related
TransformationExceptions that are thrown in the SurfaceProvider that
will be called on the GL thread.

This reinstates the permissive behaviour removed by

Test file created by opening bear.opus in a hex editor and naively
duplicating the two header packets, starting at (and including) the
first `OggS` in the file and ending just before the third `OggS`.

This ensures the 'use X instead' message is easily visible in the

Once the more advanced GlTextureProcessor interface exists,
it will be possible to change the output size of a GlTextureProcessor
between frames. To keep the re-configuration based on the frame sizes
minimal, things indepedent of the frame size, such as the GlProgram,
can be initialized in the constructor.

The current verion of AGP warns it doesn't support Android API 32 [1].

The wrapper was upgraded with ([instructions](https://docs.gradle.org/current/userguide/gradle_wrapper.html#sec:upgrading_wrapper)):
```shell
$ ./gradlew wrapper --gradle-version 7.4.2 --distribution-type all
```

[1]
```
WARNING:We recommend using a newer Android Gradle plugin to use compileSdk = 32

This Android Gradle plugin (7.0.3) was tested up to compileSdk = 31

This warning can be suppressed by adding
    android.suppressUnsupportedCompileSdk=32
    to this project's gradle.properties

    The build will continue, but you are strongly encouraged to update your project to
    use a newer Android Gradle Plugin that has been tested with compileSdk = 32

Add bitrate check to the "can encode" criteria.

This value only existed to allow setting media URLs from external sources
(e.g. in a MediaController) so that a player can start playing this item.
Now that we have MediaItem.RequestMetadata.mediaUrl we can remove this value
from MediaMetadata because it's request metadata, not media metadata.

PiperOrigin-RevId: 451857413

These fields can be used to transport additional request properties
when the requester doesn't know the details needed for the actual
playback (i.e. the LocalConfiguration).

ExoPlayer applies a large time offset to buffers so that, if the input has negative timestamps, generally buffers seen by the decoders should have positive timestamps. Modify how the offset is handled in `Transformer` so that decoders and encoders generally see positive timestamps, by leaving the offset on samples when reading them in the base renderer (remove the code that removed the offset), and then removing the offset when muxing. Also update the frame processor chain and slow motion flattening code to retain the existing behavior after this change (these both need original media presentation timestamps)

Tested via existing end-to-end tests and manually verified that the overlay frame processor shows the expected original media timestamps.

Aside: we don't need the same logic as ExoPlayer to track stream offsets across the decoder yet, because we don't try to handle stream changes during playback in single asset editing. (There is an edge case of multi-period DASH that may not work but I doubt anyone will use that as input to `Transformer` before we change the code to handle multi-asset properly.) In future we should try to refactor interaction with the decoder to use the same code for Transformer and ExoPlayer.

Most devices won't support 8k decoding, so they'll skip this test entirely.

As the video is quite short, this test shouldn't be any longer than the nearby,
long-running 4k60 test.

Unconditionally sleep for offload, if the audio buffer is full.
Previously ExoPlayer would not sleep if the expected wake-up was
in 2s. This was to prevent underrun if the wake-up was delayed.

Experiments have shown that the wakup audio buffer is far more
than 2s (around 1min). Additionally,
the metric was incorrect because it measured both,
AudioTrack + DSP.

Finally, this metric was erroneous after a gapless transition,
when the head position would reset to 0 and thus the computed
delay until next wakeup was too large.

SSIM calculation requires the input and output dimensions to be identical.

For devices that can't encode the input dimensions, skip SSIM calculations and
log the cause. Only apply this on tests where the encoder may not support the
input file dimensions.

PiperOrigin-RevId: 451364904

Decode-only video frames (needed when the frame at / first frame after the
clipping start is not a key frame) need to be decoded but not passed to
the frame processor chain or encoder.

The clipping start offset needs to be removed from the frame timestamps
in the passthrough and video pipelines.
There are no changes needed for this in the audio pipeline, as it doesn't
use the input timestamps -- it uses its own timestamps derived from the
buffer sizes instead.

Also add demo option to try this out.

There's no need to manually construct a 'default'
DefaultDataSource.Factory instance, we can just pass the `Context` to
`DefaultMediaSourceFactory` and let it construct the
`DefaultDataSource.Factory` internally.

Also update names of implementations to match design doc.
In follow-ups, SingleFrameGlTextureProcessor will become
an abstract implementation of a new GlTextureProcessor
interface.

Texture processor makes sense as it processes OpenGL textures.
The term frame processor will be used for something else in
follow-ups.

* Rename (via deprecation)
  `MediaItem.DrmConfiguration.Builder#forceSessionsForAudioAndVideoTracks`
  to `setForceSessionsForAudioAndVideoTracks`. This is more consistent
  with existing 'force' method names both in this class and in
  `TrackSelectionParameters.Builder`.
* Add missing `@Nullable` annotation to the parameter for
  `MediaItem.SubtitleConfiguration.Builder#setMimeType`. This annotation
  is already present on the `MediaItem.SubtitleConfiguration#mimeType`
  field that this setter corresponds to.

There is a problem with the ImageReader formats used by the
SSIM helper that only occurs for Nexus 5 API 21, so as a workaround
we can skip the SSIM calculation on Nexus 5 API 21.

This skips just the SSIM calculation (by setting the value to
1.0 instead and logging). The tests still run when SSIM is skipped
so that we can detect other failures.
