`SilentAudioGenerator` could output a fractional audio frame, and this could cause downstream components to throw because of trying to read a complete audio frame but only seeing a partial one.

Calculate the output buffer size based on the frame size (which is a no-op for stereo 16-bit audio) and calculate a total number of frames to output then multiple by the frame size.

isLoading is not allowed to be true when IDLE, so we have to set to
false when stopping in case it was set to true before.

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.

calls setbounds() on the drawable as the bounds of a drawable must be set for the .draw() method to work as noted in the [Drawable Documentation](https://developer.android.com/reference/android/graphics/drawable/Drawable#draw(android.graphics.Canvas)).

The duration in TransformerInternal.ComponentListener is set on the
Transformer internal thread, and is read on the playback thread. Making
this field volatile ensures that the playback thread reads the updated
value.

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

The folder type has a mix of information about the item. It shows
whether the item is browsable (type != FOLDER_TYPE_NONE) and
which Bluetooth folder type to set for legacy session information.

It's a lot clearer to split this into a boolean isBrowsable and
use the existing mediaType to map back to the bluetooth folder type
where required.

folderType is not marked as deprecated yet as this would be an API
change, which will be done later.

This adds support for the release handling. To align with the
established behavior in ExoPlayer, the player can only call
listeners from within the release methods (and not afterwards)
and automatically enforces an IDLE state (without listener call)
in case getters of the player are used after release.

Rename ERROR_CODE_OUTPUT_FORMAT_UNSUPPORTED to
ERROR_CODE_ENCODING_FORMAT_UNSUPPORTED.

This makes the error code more consistent with ERROR_CODE_DECODING_FAILED on the
decoding side. Also, the error code is in the "Encoding errors (4xxx)" section,
so muxer errors probably should be in the "Muxer errors (7xxx)" section instead.

Additionally, no muxer errors currently seem to use
ERROR_CODE_OUTPUT_FORMAT_UNSUPPORTED, so this should be a safe change.

This is necessary to move video slow motion flattening to the
AssetLoader because this step can change the duration. As we use the
duration before flattening to calculate the progress, we must also use
the position before flattening.

These terms are easier to understand, and make sense in the context of
MatrixTextureProcessor now that a MatrixTextureProcessor may have a
different input and output transfer.

Modify FrameProcessor and MatrixTextureProcessor interfaces to support
different input and output color transfers. Does not implement conversion between
color ranges (ex. HDR and SDR), but should allow for conversion between color
transfers of the same color range (ex. HLG and PQ).

This supports in-app tone mapping, where we need a single FrameProcessor to
input HDR color transfers (ex. HLG/PQ) and output SDR (ex. gamma2.2). This also
supports previewing, where we need a single FrameProcessor to be able to input HLG
and output PQ.

Manually tested by confirming colors still look right on SDR and HDR videos
with a rotation and color affect applied.

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'.)
