Before this change, calling read after reaching the end of input in an Ogg file
would cause an IllegalStateException.

The exo_controls_background view is supposed to fill its parent,
and so previously used match_parent to do this. However, if the
parent uses wrap_content for its own dimensions, the constraints
being specified become somewhat ambiguous. The parent is supposed
to be sizing itself to wrap its children, and one of the children
is supposed to be sizing itself to match the parent.

Intuitively for this case, you'd hope that the layout logic would
size the parent to wrap its other children, and that the
match_parent child would then fill the parent with its determined
size. That's not what happens, and instead the parent ends up
expanding to occupy all of the space available to it.

This commit sets the exo_controls_background view's dimensions
to be 0dp in the layout, to stop it from influencing the size of
the parent. It's then expanded to fill the parent in code.

All Player methods should throw
NotSupportedException.
Making it abstract prevents the compiler catching
non implemented methods.

PiperOrigin-RevId: 364974387
The BasePlayer implementation of add/remove
Listener knows about Components.
As those are removed from the Player
interface, the implementation of those
methods needs to be moved down in Player
implementations.

This commit makes no functional change.

The hacky workaround for APIs 29/30 doesn't work on API 31. Instead,
we can use the onDisplayInfoChanged callback, that is accessible from
API 31.

Fix WebViewSubtitleOutput to respect this (CanvasSubtitleOutput already
does).

Issue: #8704
PiperOrigin-RevId: 365534018
A TrackGroup must contain the same content in all Formats (except for
the quality, encoding etc). Verify that the language and role flags
are the same and log an error if don't match. Don't throw to avoid
breaking existing use cases that just happen to work by chance.

The extended onPositionDiscontinuity callback can be used to improve some
listener classes:
 - Listening to onTimelineChanged to detect discontinuities is no longer needed.
 - Listening to onSeekStarted is no longer needed as the start position is part
   of the onPositionDiscontinuty callback.
 - The exact old position is also useful for media time history logging.

As a side effect, removing onSeekStarted handling from PlaybackStatsListener
fixes Issue: #8675 that was caused by the special EventTime handling for
onSeekStarted.

If the player is created on a background thread (which is allowed
as the only exception to the access-on-one-thread-only rule), it
may happen that a callback on the main thread tries to access the
player before the constructor even finished. This is dangerous and
can cause exceptions due to uninitialized variables.

To solve this, we can make sure that every player access is blocked
until the constructor finished. Blocking is safe because the
constructor itself is not doing any blocking work or acquiring locks.

The thread verification method is already called on every entry
point to the player, so we can reuse the same method for checking.

This is generally not supported by our classes. A similar change for audio
was made in aa2beb0.

Aims to achieve visibility parity with MediaCodecRenderer#onQueueInputBuffer.

Allows measuring the time when the codec queue the first input buffer in the codec. Which means the Codec has been initialized and is about to start decoding.

It also allows measuring how long it takes for the Codec to render its first frame.

We remove other source related listeners if a MediaSource is
removed from the playlist or the player/source is released.
This isn't currently done for the DRM listener.

Release is a life cycle operation that should only be called when
the player is no longer needed. It's linked to the player lifecycle
and thus very different from prepare/stop.
As a result, it should not be in the same command.

Additionally it's not clear if remote players will ever need to call release,
as the player creator is best candidate to release it.

As a result the release operation doesn't have a use case for a command.
A release command can be added later if a need is identified.

The ForwardingPlayer implements the Player interface and forwards all
operations to another Player instance. Apps will be able to override
methods of ForwardinPlayer in order to modify and/or suppress specific
Player funcionalities.

This commit introduces the ForwardingPlayer which simply forwards all
Player operations to another Player instance. In follow-up changes,
the ForwardingPlayer will be extended so that it eventually reaches the
feature-set offered by ControlDispatcher.

1. Clarify intention of getAdGroupIndexForPositionUs and
   getAdGroupIndexAfterPositionUs. Both methods are used for very
   specific but different purposes and encode the logic of which
   ads should be played at which time, so it's helpful to clarify
   this in the documentation as well.
2. Change one usage getAdGroupIndexForPositionUs to use the already
   existing nextAdGroupIndex. This is also more in line with the
   intended usage as clarified in step 1.
3. Update MediaPeriodQueueTest for updateQueuedPeriods to only
   look for duration changes in future periods, not in the
   current one, because that's not handled MediaPeriodQueue for ads
   and the test is just passing by chance now. Also remove wrong
   advancePlaying() calls that are already implicitly included in
   the preceding enqueueNext() call.
4. Fix a minor bug where post-roll ads are not checked whether they
   are played already before using them as the next ad group. Also
   added a test covering this case.

Move VideoSize in the common module and have the Player return it.

`Listener` and `AnalyticsListener` `onVideoSizeChanged` are updated
with the old method deprecated.

`VideoRendererEventListener.onVideoSizeChanged` was also migrated to
`VideoSize` but the old method is removed, not deprecated.
This is because:
 - apps calling/listening to this method is a rare and niche use-case.
 - it would introduce hard to diagnostic issues where if only the caller
   or the callee is updated to use the new method, the event will be lost.
   This doesn't occur with the other 2 listeners as the caller is always
   in ExoPlayer library and was updated to call both the old and new methods.

VideoSize is used everywhere except in `Format` as this would lead to
too much refactoring and backward compatibility breakage for little gain.

This change adds an API in the ForwardingPlayer to disable commands.
This is affecting what Player.isCommandAvailable() returns as
well as what is being advertised from the
EventListener.onAvailableCommandsChanged() callback.

For the callback case, the ForwardingPlayer needs to intercept the
callback. It does so by wrapping registered EventListener and Listener
instances, which resulted in some boiler-plate code. In addition, there
is logic on the wrapped listeners to avoid triggering a queued callback
if all listeners have been removed in the meantime. This includes the
case where new listeners are added while callbacks scheduled for the
removed listeners are still pending.
