Based on [this conversation thread](https://chat.google.com/room/AAAA--f88ao/76Rem_cRCK8), I've opted to update the existing FrameProcessor.create() rather than deprecate it, as it is unlikely to be in use by apps outside google3.

Before this CL, the `renderedLastFrame` flag is not set if the last frame is released immediately (force render), or when it's dropped.

Flushing resets all the texture processors within the `FrameProcessor`. This
includes:
- At the back, the FinalMatrixTextureProcessorWrapper, and its MatrixTextureProcessor
- At the front, the ExternalTextureManager
- All the texture processors in between
- All the ChainingGlTextureProcessorListeners in between texture processors
- All the internal states in the aforementioned components
The flush process follows the order, from `GlEffectsFrameProcessor.flush()`
1. Flush the `FrameProcessingTaskExecutor`, so that after it returns, all tasks queued before calling `flush()` completes
2. Post to `FrameProcessingTaskExecutor`, to flush the `FinalMatrixTextureProcessorWrapper`
3. Flushing the `FinalMatrixTextureProcessorWrapper` will propagate flushing through, via the `ChainingGlTextureProcessorListener`

AudioProcessor-based speed changes are not supported with
offload, so we should use the AudioTrack-based speed changes
by default if the user requests a speed change.
This moves the decision of which speed change path is used
into the Configuration, so that it can change for each
AudioTrack in a playlist.
PiperOrigin-RevId: 505621911
This makes it easier to reason about some parts of the code and
will eventually allow to easily switch between AudioProcessor-
based on AudioSink-based speed adjustment.
The current state saves the applicable playback parameters
in separate variables depending on which speed adjustment
path is used. Moreover, the AudioProcessor-based logic keeps
a chain of pending parameter changes and we derive the last
applicable one everytime we need the current parameters.
After this change, this is simplified by
- keeping a common value for playback parameters independent
of the actual path we use for adjustment.
- keeping the final ("current") parameters directly, instead
of deriving it from a chain of yet to be applied parameters.

`FrameProcessorManager` now reports it's not ready when the output surface is set but not the output resolution. `FrameProcessorManager` allows playback without an output surface, like with ExoPlayer.

Resampling as a term is overloaded, however it was raised as a
confusing term in a meeting recently, as the 1P team initially thought
this would change the sample rate. The naming of this `AudioProcessor`
now matches `ToInt16PcmAudioProcessor`.

This is needed for constrained multi-asset to shift the timestamps of
the media items that are not the first in the sequence.
PiperOrigin-RevId: 502409923
Previously, after calling MCVR.setOutput() with null, `frameProcessorManager`'s output surface is cleared. What was unexpected is `ExoPlayerInternal` notifies a zero output resolution after clearing the output surface. This zero resolution causes FrameProcessor to fail.

Starting with Android 13 (API 33) an app needs to request the
permission to post notifications or notifications are suppressed.
This change documents this in the class level JavaDoc of the
`DownloadService`.

When audio processors are enabled during tunneling, they must produce
output immediately, ensuring that the timestamps of the output samples
correspond to the input and that no additional samples are produced.
This requirement is documented in the Javadoc of DefaultAudioSink.
However, this alone doesn't guarantee all buffers are immediately
written to the AudioTrack, because the AudioTrack writes are
non-blocking and may need multiple attempts.
When draining the audio sink at the end of the stream, we currently
fail in this situation because we assert that the timestamp must be
set (=the drain operation is a no-op). But this may not be true when
the previous non-blocking write wasn't fully handled. We can fix this
by saving the last timestamp and reusing it during draining.

Initialising the fields as Integer and then getting a String on compute time is slow. Instead we directly initialise these fields as String. Improves the time taken in bundling PlayerInfo further to less than 200ms from ~300ms.
Also modified a test to improve productive coverage.

FrameProcessor already support using different transfer function for input and
output color. This CL has two major changes:
- Create an eglSurface that recognizes BT.2020 PQ
- This requires a separate extension that works only after 33
- So we current throw, if input is HDR, and this extension doesn't work
- Create FrameProcessor with PQ output transfer function
PiperOrigin-RevId: 496023758
The tunneling callbacks are sent via Handler messages and may be
handled after the codec/surface was changed or released.
We already guard against the codec/surface change condition by
creating a new listener and verifying that the current callback
happens for the correct listener instance, but we don't guard
against a released codec yet.

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).

The `MediaItem` instances in the following cases are not actually empty but acts as a placeholder. `EMPTY_MEDIA_ITEM` can also be confused with `MediaItem.EMPTY`.
PiperOrigin-RevId: 495843012
It covers the following cases:
| From/To | `null` | `surface 0` | `surface 1` |
|-------------|--------|-------------|-------------|
| `null` | 🆖 | 📺 | 📺 |
| `surface 0` | ❌ | 🔁 | 📺 |
| `surface 1` | ❌ | 📺 | 🔁 |
Where
- 🆖 means NOP
- ❌ means
- Set `null` on FrameProcessor, effectively dropping all frames
- 📺 means
- Notify the listener of video size
- Set FrameProcessor output surface and size when MSG_SET_VIDEO_OUTPUT_SIZE is received
- 🔁 means
- Notify the listener of video size

BasePlayer simplifies implementations by handling all the various
seek methods and forwarding to a single method that can then be
implemented by subclasses. However, this loses the information about
the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.

- Use a single `VideoSize` instance instead of four primitive fields.
- Clarify that the reported size is the decoded size, that is the encoded video
size.

Some Player methods like getting the Looper and adding listeners
were always allowed to be called from any thread, but this is
undocumented. This change makes the threading rules of these
methods more explicit.
Removing listeners was never meant to be called from another thread
and we also don't support it safely because final callbacks may
be triggered from the wrong thread. To find potential issues, we
can assert the correct thread when releasing listeners.
Finally, there is a potential race condition when calling addListener
from a different thread at the same time as release, which may lead to
a registered listener that could receive callbacks after the player is
released.

An AndroidTest is needed to test the message sending from ExoPlayerImpl to
a video renderer (MCVR in this case). The test will be added later.

These have the same value (`-1`), and basically the same meaning (offset
in an array/list/file/byte stream/etc), but 'position' is an overloaded
term in a media playback library, and there's a risk people assume that
methods like `Player.getCurrentPosition()` may return
`C.POSITION_UNSET`, when in fact unset media times (whether duration or
position) are always represented by `C.TIME_UNSET` which is a) a `long`
(not `int`) and b) a different underlying value. (aside:
`getCurrentPosition()` never returns an unset value, but it's a good
example of the ambiguity of the word 'position' between 'byte offset'
and 'media timestamp'.)
PiperOrigin-RevId: 492493102
This inconsistency was exposed by an upcoming change to deprecate
`POSITION_UNSET` in favour of `INDEX_UNSET` because position is an
ambiguous term between 'byte offset' and 'media position', as shown
here.

Our FakeClock generally makes sure that playback tests are fully
deterministic. However, this fails if the test uses blocking waits
with clock.onThreadBlocked and where relevant Handlers are created
without using the clock.
To fix the flakiness, we can make the following adjustments:
- Use TestExoPlayerBuilder instead of legacy ExoPlayerTestRunner
to avoid onThreadBlocked calls. This also makes the tests more
readable.
- Use clock to create Handler for FakeVideoRenderer and
FakeAudioRenderer. Ideally, this should be passed through
RenderersFactory, but it's too disruptive given this is a
public API.
- Use clock for MediaSourceList and MediaPeriodQueue update
handler.
