I've removed the "by default" statements, since this now depends on how
the builder was configured.

This ensures BUFFER_FLAG_DECODE_ONLY is set on samples that are
before the playback start position, in the case that the queue
is created after the start position is set.

When playing TrueHD streams, it's possible that the first decoded
buffer is empty, and that the channel count and sample rate are
still unknown. To correct for this, defer determining the format
until a buffer that will actually be output from the decoder has
been obtained, and only then query the channel count and sample
rate.

The condition is meant to be unblocked whenever the constructor is
left. This should include unchecked exceptions (that may be thrown
due to bugs in the dependent components, or user-inhected factories)

The buildscript entry is required by
com.android.tools.build:gradle:4.0.1.

For other projects, it appears that org.checkerframework is
in jcenter.

Without this change building with gradlew is broken, at least.

again or the player is released.

Add an allowlist of Metadata.Entry implementations with stable toString

The dumped output should include metadata, but doesn't because of
Issue: #8710. The fix is in a follow-up change.

When playback transitions automatically, the timeline may have changed because the cast device learned about the duration of the next media item and includes this in the new media status that is sent to the CastPlayer. In such a case we need to make sure that we don't report a media item transition with reason PLAYLIST_CHANGED but for reason AUTO.

The new onPositionDiscontinuity callback contains sufficient information, so
that this former workaround to obtain the position before a seek is no longer
needed.

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.

This is generally not supported by our classes. A similar change for audio
was made in https://github.com/google/ExoPlayer/commit/aa2beb080c6f621264527a6147a258bdd7f0fa27.

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.

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.

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.

does).

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.

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.

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

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.
