Ads can appear due to asynchronous ad tag requests completing after
earlier ads in a pod have loaded, so remove the requirement that the
ad count can't change. The MediaPeriodQueue should handling discarding
buffered content if an ad appears before already buffered content, so
I think this case is actually handled correctly by the core player
already.
Also remove the requirement that an ad URI can't change. This is a
defensive measure for now, but it's likely that a later fix in the IMA
SDK for an issue where loadAd is not called after preloading then
seeking before a preloaded ad plays will result in loadAd being called
more than once, and I think it's possible that the second call to
loadAd may have a different URI. Because the ad URI should only change
after an intermediate seek to another MediaPeriod, there shouldn't be
any problems with buffered data not getting discarded.

The test was trying to synchronize a background decoding thread by
waiting for pending decode calls. However, the background thread needs
to fully queue the newly available output buffer before we can stop
waiting to ensure it's actually fully predictable. So we change the
pending wait to wait until the input buffer is cleared, which only
happens after the decoder is definitely done with it.
Also properly clean-up decoder (including shutting down the background
thread).

- Leaving the TODO, since there are still MIME types we're unsure about.
- Removing AAC because xHE-AAC does not have this property. We may re-add
it with an additional profile check to exclude xHE-AAC in the future.

We haven't seen it used anywhere in practice. It's a niche feature not
supported by any other extractors, and is one of the very few things
stopping us from simplifying MediaSource implementations to not set the
decodeOnly sample flag. This is a simplification that we want to make,
since the current mechanism doesn't work properly for cases where a
downstream decoder adjusts the buffer presentation timestamps so that
they're different on the output side than on the input side.
PiperOrigin-RevId: 316712302
This flag isn't needed anymore because the waiting for keys happens on
the source side and the source just returns NOTHING_READ under the
same conditions.

We started using this method from other tests unrelated to

This change adds MediaSource.getMediaItem and deprecates MediaSource.getTag. For backwards compatibility, the tag is made available through the Window with `mediaItem.playbackProperties.tag` as well as in the deprecated `tag` attribute.

Using the default offset as a magic constant makes tests hard to

The correct order of initializing the MediaCodec should be (as per
documentation
https://developer.android.com/reference/android/media/MediaCodec#initialization)
"create -> setCallback -> configure -> start"
but the MediaCodecRenderer currently does
"create -> configure -> setCallback -> start"
MediaCodec implementations did not complain about this so far, but the
wrong sequence does not work with the MediaCodec in block mode (new mode
in Android R) and also the ShadowMediaCodec won't operate in
asynchronous mode otherwise. To initialize the MediaCodec in the correct
order, this commit adds configure() in the MediaCodecAdapter so the
MediaCodecRenderer can do:
adapter.configure(); // sets the callback and then configures the codec
adapter.start(); // starts the codec

The test uses two items with period-in-window offsets and a non-zero default start position. The test also prepares the first item lazily so
that the start position (and thus the renderer offsets) need to change.
This is arguably the most complicated setup that needs to be tested.

The option to cancel ongoing loads as part of the queue size evalation
was added recently. This split out the decision to a new method so that
a TrackSelection implementation can independently cancel loads and
discard upstream data. It also clarifies that evaluateQueueSize will
only be called if there is no ongoing load.

Output timestamps are calculated by the codec based on the buffers,
which is offset in Codec2. This adjusts the input timestamps as they
are passed in so they will match the output timestamps produced by
the MediaCodec.

FakeMediaSource and FakeTimeline should put a media item to the window just as other media sources and timelines do. This change provides a fake media item for both of them.
Further the MaskingMediaSource needs to provide a media item for when the real timeline of the masked media source is not available. This can be easily done by using mediaSource.getMediaItem() once available. For now a dummy is used to make ExoPlayerTest run green. This can be easily change to use mediaSource.getMediaSource as soon as this method is defined by the MediaSource interface.

This change makes the media item of Timeline.Window non-null by providing a fallback media item in window.set(...). After having migrated all media sources this should not be needed anymore, but a fallback makes it more safe than just making the mediaItem argument of window.set(...) non-null (which is done in a following CL in this chain of CLs).

Before loading a new chunk, the player will call reevaluateBuffer
anyway, so we don't have to do this directly after cancelation.
This simplifies some logic because we can remove the pending queue
size variable.

If no deprecated methods on the factory is called, the media item instance that is passed to the createMediaSource method must be passed down to the constructor of the media source.

If the sample times don't overlap and are independent, splicing makes no

We aim to have the same media item instance published in the timeline that is passed to the createMediaSource(mediaItem) method. This means when the manifest uri is manually replaced by a developer, the media item published in the next timeline update is still the same.
Note: This leads to the fact that the manifest published in that timeline is loaded from a different URI than the URI of the media item in the same timeline.

- The new CacheWriter is simplified somewhat
- Blocking on PriorityTaskManager.proceed is moved out of
CacheWriter and into the Downloader tasks. This is because
we want to shift only the caching parts of the Downloaders
onto their Executors, whilst keeping the blocking parts on
the main Downloader threads. Else we can end up "using"
the Executor threads indefinitely whilst they're blocked.

Add an `_` in long constants.

The test was flaky because it didn't wait for pending commands to finish

Sometimes it's useful to be able to block until something on some other thread
"really has finished". This will be needed for moving caching operations onto
the executor in Downloader implementations, since we need to guarantee that
Downloader.download doesn't return until it's no longer modifying the
underlying cache.
One solution to this is of course just to not interrupt the thread that's
blocking on the condition variable, but there are cases where you do need to do
this in case the thread is at some other point in its execution. This is true
for Downloader implementations, where the Download.download thread will also
be blocking on PriorityTaskManager.proceed. Arranging to conditionally
interrupt the thread based on where it's got to is probably possible, but seems
complicated and error prone.

Every timeline refresh currently assumes that it corresponds to a manifest
refresh and issues the respective load events. However, there are other
timeline updates that don't have a manifest refresh (e.g. ad state updates)and thus shouldn't issue these events.

This change adds an overloaded createMediaSource method which allows developers to pass in a media item with a in-memory manifest.

Previously if the AudioCapabilities reported that an encoding/channel count was
supported, DefaultAudioSink could try to play it via passthrough. However,
DefaultAudioSink does not support passthrough of every possible format (for
example, it's likely that AAC passthrough does not work given it's never been
tested and recent GitHub issues indicate that trying to use it leads to no
audio being played).
Add additional checks to make sure the encoding is in the list of encodings that
are known to work with passthrough in DefaultAudioSink.

The new behaviour:
- If the session is successfully opened, an acquire event is dispatched
to all attached dispatchers.
- If acquire() is called but the session is already open, the acquire
event is dispatched only to the dispatcher provided in to acquire()
- If the session is successfully released, a release event is dispatched
to all attached dispatchers (in theory at most one should ever be
attached at this point).
- If release() is called but the session isn't released (because
referenceCount > 0) then a release event is dispatched only to the
dispatcher provided to release().

EventTime contains information about when an event happened and where
it belongs to. Both places can be fully described using timeline, window
index, media period id and position.
Right now, only the information for where the event belongs to is fully
contained in EventTime, whereas the time when the event happened only has
the position, and none of the other information (timeline, window, period).
This change adds the missing information, so that the EventTime can easily
be used without having access to the Player. This also ensures Event
metadata is self-contained and can be stored and reused later.
