The player may suppress playback when waiting for audio focus even if the
state==Player.READY. There is currently no getter or callback to obtain this
piece of information for UI updates or analytics.
Also, it's a important derived state to know whether the playback position is
advancing. Add isPlaying and the corresponding callback to allow retrieving
this information more easily.

If we use the default start position, we currently resolve it immediately
even if we need to play an ad first, and later try to project forward again
if we believe that the default start position should be used.
This causes problems if a specific start position is set and the later
projection after the preroll ad shouldn't take place.
The problem is solved by keeping the content position as TIME_UNSET (= default
position) if an ad needs to be played first. The content after the ad can
then be resolved to its current default position if needed.

It's only thrown in an edge case on API level 20 and below. If it
is thrown it causes playback failure when playback could succeed,
by throwing up through configureCodec.
It seems better just to catch the exception and have the codec be
configured using the format's own width and height.
PiperOrigin-RevId: 251745539
We currently don't display the last frame because the seek time is behind the
last frame's timestamps and it's thus marked as decodeOnly.
This case can be detected by checking whether all data sent to the codec is
marked as decodeOnly at the time we read the end of stream signal. If so, we
can re-enable the last frame. This should work for almost all cases because the
end-of-stream signal is read in the same feedInputBuffer loop as the last
frame and we therefore haven't released the last frame buffer yet.

For decoder reuse, we want disable() to flush the decoder. However,
if the flush needs to release the decoder for some reason, it seems
non-ideal to immediately re-initialize it. Re-initialization can
also throw ExoPlaybackException, which we don't want for disabling.
This change allows a variant of flush that wont re-initialize the
decoder if it has to be released, which will be used from disable().

If we prepare a deferred media period before the actual timeline is available,
we either prepare with position zero (= the default) or with a non-zero
initial seek position.
So far, the zero (default) position got replaced by the actual default position
(including any potential non-zero window offset) when the timeline became known.
However, a non-zero initial seek position was not corrected by the non-zero
window offset. This is fixed by this change.
Related to that, we always assumed that the deferred media period will the
first period in the actual timeline. This is not true if we prepare with an
offset (either because of an initial seek position or because of a default
window position). So, we also determine the actual first period when the
timeline becomes known.

Currently, we are using 2 copy steps for PixelCopySurfaceCapturerV24:
- Copy from the source surface to a similarly sized bitmap (using PixelCopy API).
- Copy from the bitmap to a scaled bitmap, based on the given output size, using scaledBitmap API.
This CL merges the 2 steps and uses PixelCopy API to perform copy directly from
the source surface to the bitmap of the given output size.
However, since our test uses scaledBitmap API to create reference bitmap from original image, due to various Bitmap copy optimizations (filtering, antialiasing etc...) that are different between PixelCopy API and scaledBitmap API implementations, the result images cannot be the same. We can perform the our tests by asserting that their PSNR value is very high, which means they are very similar.

All media periods are part of a queue of windows buffered and played by
ExoPlayer. When repeating windows, the current MediaPeriodId is insufficient
to distinguish between the repetitions of the same period. This makes it hard
to see to which media period load events belong to, and it is also difficult to
determine whether two media periods belong to the same logical window or
whether they are part of different repetitions of the same window.
Therefore this change adds a unique sequence number to each window in the

So far this wasn't possible because Robolectric's Looper and MessageQueue
implementations have multiple shortcomings:
1. The message loop of new HandlerThreads is an not an actual loop and
scheduled messages are executed on the thread the message is enqueued
(not the handler thread).
2. The scheduler used to replace the message queue is synchronizing all its
methods. Thus, when a test attempts to add messages to a Handler from
two different threads, it may easily run into a deadlock.
3. The scheduler doesn't correctly emulate the order of messages as they
would be in an actual MessageQueue:
a. If the message is enqueued on the handler thread, it gets executed
immediately (and not after all other messages at the same time).
b. The list of messages is always re-sorted by time, meaning that the
order of execution for messages at the same time is indeterminate.
4. Robolectric's SystemClock implementation returns the current scheduler
time of the main UI thread. So, unless this scheduler is used to add
messages in the future, the SystemClock time never advances.
This CL adds two helper classes which extend and replace Robolectric's
ShadowLooper and ShadowMessageQueue.
1. We intercept messages being enqueued or deleted in the message queue.
Thus Robolectric's faulty scheduler gets never used. Instead, we keep
a blocking priority queue of messages, sorted first by execution time
and then by FIFO order to correctly emulate the real MessageQueue.
2. We also keep a list of deleted messages to know which messages to ignore
when they come up in the looper.
3. When a new Looper is started, we override the dummy loop to an actual
eternal while loop which waits for new messages, checks if they haven't
been deleted, and runs the messages (similar to what Robolectric's
MessageQueue would have done at this point).
Because we don't actually use the main UI thread in our tests, we can't rely
on the SystemClock to progress in any sensible manner. To overcome this issue,
we can use the auto-advancing FakeClock also used for the simulation tests.

This achieves two things:
1. All our tests use the same type of assertions.
2. The tests currently run as instrumentation test can be moved to
Robolectric without changing the assertions.

These were caused by two issues:
1. The FakeMediaSource can be updated with a new timeline. The setNewSourceInfo
is called from a different thread than prepareSource and both access local
variables without synchronization.
2. For multi-window playback, the FakeRenderer claims that isReady and isEnded
are both set to false if it read the end of the stream. However isReady should be
true because it is able to "render" its data until the end of the stream.

This fixes a very specific case where the data read has non-cached gaps
and a read-only CDS switches to read from upstream in a gap then the
cached data is deleted. When the CDS reaches the end of the gap, it
tries to open the next source. As there is no cached data, it tries to
continue with the already opened upstream data source but as it reached
end of the gap range, the code starts looping.
Also fixes infinite lock which occurs when in the previous case CDS isn't
readonly. It locks the content while filling the gap in the cache. At the
end of the gap, as the following data is deleted it tries to lock the
content for writing but the content is already locked by itself.
The last fix is preventing removal of CachedContent entry from
CachedContentIndex while associated key is locked.

Some tests in ExoPlayerTest issue commands to the player from the test thread
while the player is actively playing media (playWhenReady=true). Due to the
indeterminate time taken to enqueue the commands on the playback thread, they
may arrive when the player already proceeded to another window or finished
playback.
To ensure the tests are always deterministic, this change pauses playback in
the tests where this may happen before issuing the commands.
Also, for tests where we need to wait for a new window before issuing the
next command, a new action is added which allows to play until a specified
position.

Partial reads were performed once using a partial size of 1 byte.
This was not enough to detect problems which only occur in combination
with IOExceptions. Partial reads are now only applied when no exception
is thrown.
Moreover, the tests didn't check whether the total number of sampled bytes
is what it is supposed to be. Added a field to the data dumps checking
the total number of bytes in the sampled data.

This removes the need to calculate the time needed to run the doSomeWork
method. Consequently, we can use both the real Clock/Handler and the
FakeClock without changing the way the playback loop works and without
violating the interfaces of Clock or Handler.

implement Handler methods. Instead, we have a separate Handler interface

This adds options to ExoPlayer.sendMessages which allow to specify a window index
and position at which the message should be sent. Additionally, the options can be
configured to use a custom Handler for the messages and whether the message should
be repeated when playback reaches the same position again.
The internal player converts these window positions to period index and position
at the earliest possibility. The internal player also attempts to update these
when the source info is refreshed. A sorted list of pending posts is kept and the
player triggers these posts when the playback position moves over the specified
position.

1. The player doesn't acknowledge phantom stops when an exception is thrown anymore.
2. It also makes sure it doesn't reset the pendingPrepareCount unless it's actually
immediately acknowledging these prepares.
3. It ensures a seek is acknowledged even though an exception is thrown during seeking.
Added tests (which previously failed) for all three cases.

In some occasions, we may want to discard a part of the buffered media to
improve playback quality. This CL adds this functionality by allowing the
loading media period to re-evaluate its buffer periodically (every 2s) and discard
chunks as it needs.

Calling it directly might skip other callbacks. For example:
ActionSchedule.Builder().waitForTimelineChanged(...).build().
is currently immediately calling through to
callback.onActionScheduleFinished when the timeline changes.
Depending on the position of the action schedule listener in the
listener set, it may skip other listeners also
listening to timeline changes.

The ExoPlayerImpl implementation forwards the stop request with this optional
parameter. To ensure correct masking (e.g. when timeline updates arrive after
calling reset in ExoPlayerImpl but before resetInternal in
ExoPlayerImplInternal), we use the existing prepareAck counter and extend it
also count stop operations. For this to work, we also return the updated
empty timeline after finishing the reset.
The CastPlayer doesn't support the two reset options so far.

A message to stop the playback and to quit the playback thread was posted in release().
The stop message removed all other already queued messages which might include
the second message to quit the thread. That led to infinite waiting in the
release method because the playback thread never got the quit signal.

Fixed by explicitly waiting for the timeline update. This shouldn't be
necessary and will be removed as soon as the correct order of events
can be guaranteed (timeline change -> state change -> onSeekProcessed).
The waiting for the timeline update is implemented by introducing the
feature that the test runner also waits until the action schedule has
finished before stopping the test.

Currently onTimelineChanged doesn't allow to distinguish easily between the
different reasons why it's being called. Especially, finding
out whether a new media source has been prepared or the current source
refreshed dynamically was impossible without tightly coupling the player
operations with the listener.
The new reasons provide this disdinction by either indicating a newly
initialized media source, a dynamic update to an existing timeline
or manifest, or a reset of the player (which usually results in an
empty timeline).
The original onTimelineChanged method without reason is kept in the
DefaultEventListener as deprecated to prevent the need to update all
existing listeners in one go.
