Before this change a timeline update of a live content
source has produced a timeline refresh before passing
the timeline to the ads loader. When in such a case
the ads loader updates the ad playback state, a
second timeline refresh is trigger that then
includes the updated ad data also. This can result
in a timeline being pulished with stale ad information.
This change prevents this by introducing a boolean
return value that requires the ads loader to signal
whether the ad playback state has been passed back
to the source. This ensures that an update of
timeline and ad playback state produces a single
timeline update and is published in sync.

ChannelMappingAudioProcessor, TrimmingAudioProcessor and
ToFloatPcmAudioProcessor are currently package-private even
though they might be useful in custom audio processing chains
or custom version of audio sinks.

The Context is currently passed right down from ExoPlayer.Builder
without ever converting it to the application context. This may
cause memory leaks if a Player is kept across activities/service
lifecycles.

This is part of the efforts for adding encoder support for ShadowMediaCodecConfig to use it for ExoPlayer and Transcoding tests.
* Replaced `ShadowMediaCodecConfig#forAllSupportedMimeTypes()` calls with `ShadowMediaCodecConfig#withAllDefaultSupportedCodecs()`
* Replaced `ShadowMediaCodecConfig#withNoDefaultSupportedMimeTypes() calls with `ShadowMediaCodexConfig#withNoDefaultSupportedCodecs()`

The current instanceof check accidentally unpacks the child,
returning the inner period instead of the one passed to the source.
PiperOrigin-RevId: 746556825
In `PreloadMediaSource` we accesses the `MediaPeriod.getBufferedPositionUs()` when we receive `onContinueLoadingRequested()` from the period. For `ProgressiveMediaPeriod` which requires loading a portion of media file to get it prepared, there is a chance that it needs more than one round of `onContinueLoadingRequested()` -> `continueLoading()` to complete preparation, for example, when the `setContinueLoadingIntervalBytes()` is small enough to not include the full information for preparation. Thus we should avoid `MediaPeriod.getBufferedPositionUs()` being called before period is prepared, as it will fail at `assertPrepared`.

We used to pass `audioTrackConfig.encoding` as the `bufferSize` parameter to `AudioSink.InitializationException`, for which this CL is supposed to correct. But `encoding` is a useful information for logging anyway, thus an `encoding` parameter is also added to `AudioSink.InitializationException` constructor, so now we pass both `encoding` and `bufferSize` parameters.

This is because the replay cache needs to clear the cache after one mediaItem is fully played.
That is, if the last two frames are cached, we need to wait until they are both rendered before
receiving inputs from the next input stream because the texture size might change. And when the
texture size changes, we teardown all previous used textures, and this causes a state confusion
in the shader program in that, the cache thinks one texture id is in-use (because it's not released)
but the baseGlShaderProgram texturePool thinks it's already free (as a result of size change)
Also fixes an issue that, if replaying a frame after EOS is signalled, the EOS
signal is lost because we flush the pipeline.

This adds the option to disable certain track types during scrubbing,
with audio and metadata disabled by default.
The tracks are disabled by modifying the `TrackSelectionParameters`,
but in a way that is invisible to
`Player.getTrackSelectionParameters()` and
`Player.Listener.onTrackSelectionParametersChanged`. This allows us to
clearly reason about what should happen if
`Player.setTrackSelectionParameters(...)` is called during scrubbing
mode. The **side effects** of disabling the tracks are all visible
through `Player.Listener` and `AnalyticsListener` (renderer disabled,
decoder released, `onTracksChanged`, etc.).

ExoPlayer disables sleeping for offload when the reading period advances and re-evaluates turning it back on when the playing period advances. For playlists of short items where the reading period could advance much further than the playing period, sleeping should still be disabled until the playing period advances to match the current reading period.

These are needed for the `waitUninterruptibly` handling, which is
really just waiting for a condition to become true on another thread
with a timeout, as well as Clock and interrupt handling.
We already have ConditionVariable that serves this purpose, which
has methods with a timeout and with interrupt handling. Adding
another version of the call with both timeout and interrupt handling
allows to replace the EPII manual code. The ConditionVariable methods
were also missing the clock calls to signal a wait operation.
PiperOrigin-RevId: 743214709
EPII currently uses 'synchronized' for two purposes:
1. `waitUninteruptably` to ensure the condition checks and
`wait` calls are atomic + the calls on the playback thread
that update these conditions to `notifyAll`.
2. Access to the `released` field that is used a condition
for `waitUninterruptibly` but otherwise only accessed on the
app thread.
We can remove the second usage by making the `released` variable
more clearly single thread on the app thread (including renaming to
make it obvious as this is the only variable in this class accessed
on that thread). The `waitUninterruptly` call for `release` can use
an `AtomicBoolean` like the other two calls to this method.
This also fixes a potential bug where a release timeout would leave
the `released` field as `false`, meaning future calls to these other
methods wouldn't be blocked early.

This also fixes the 'unsuitable output' logic incorrectly overriding
the `@PlayWhenReadyChangeReason` when only the playback **suppression**
state has changed.

Applications providing custom `AudioSink` implementations should have the dynamic scheduling for audio playback fallback to the static interval if they are not implementing `AudioSink#getAudioTrackBufferSizeUs()`.

This initial version prevents incoming seeks from pre-empting
in-progress seeks, allowing more seeks to complete when the scrubber
bar is dragged quickly back and forth.
More scrubbing optimizations will be added in follow-up changes.

When an ad is inserted into a live period with an unset
duration, the live period needs to be wrapped with a
`ClippingMediaPeriod` and then actually be clipped to
the end position when the duration gets known. Without
this the renderers will never see an EOS which prevents
the reading/playing period from advancing.
In the case of a server side inserted ad on the other
hand, the actual clipping needs to be prevented to
keep the current behavior for SSAI streams. In an SSAI
stream, an ad inserted before the current position should
not produce a snap back to the newly inserted ad. This is
currently prevented in both places, when the updated
timeline is handled to not disable the renderers, and when
the `mediaPeriodQueue` updates the queued periods. This
behaviour is preserved to not create side effects of this
change.

- Only have the primary sequence renderers listen to
PlaybackVideoGraphWrapper events. These events only need to be
forwarded to a single ExoPlayer instance.
- Set the DefaultVideoSinkListener only once.
PiperOrigin-RevId: 742636455
Some DefaultVideoSink methods are called once per sequence, but this
doesn't make sense as the DefaultVideoSink is connected to the
VideoGraph output. This CL calls the DefaultVideoSink method only for
the primary sequence.
The other problematic DefaultVideoSink method calls will be moved in
follow-up CLs.
This is part of the effort to prepare PlaybackVideoGraphWrapper for
multi-sequence.

The tests passed because of an issue in chaining. The chaining listener allows
self-looping, i.e. the producer and the consumer of a frame could be the same
instance. Like an effect chain of `a -> a -> b` This didn't fail any test
before, because the chaining is rectified when connecting a to b, but it should
have failed when connecting a to a.

We don't require high precision in the calculation of `percentDownloaded` for `Downloader.ProgressListener.onProgress` though, when `byteCached == contentLength`, we hope the `percentDownloaded` to be `100f` (rather than `99.99999f`). The result of `byteCached * 100f` can be less precise as the floating-point numbers are sparser when the value is far from zero. For example, if `byteCached == 812345L`, then the `byteCached * 100f` will become `81234496` (value checked by `BigDecimal`).

If a recoverable renderer error occurred just before playing period transition(aka media item transition) then the player may enter a continuous loop of retrying to play the previous media item.
This was most easily reproduced in an audio offload scenario where init in offload mode always fails. In initializing the following media, the process would fail with recoverable error to try in non-offload mode. The player would try to recover with playing the previous media item. Most times it would skip to the next track but not always.

It's unclear why the listeners would need access to the
PlaybackVideoGraphWrapper as there should always be only one. Also,
it's not common practice to pass the parent object to the listener in
media3 (see Player.Listener for example).

For now, even if a recoverable error occurs during pre-warming, the current process will be that pre-warming is disabled until subsequent media item transition.

This is a step towards unifying ShadowMediaCodecConfig structure to accommodate both ExoPlayer and Transcoding codecs configuration.
This change abstracts the codec information to a separate `CodecInfo` class. This allows having codecs with the same information configured with different configurations (passthrough/frame-dropping, decoder/encoder). It also does the following:
* Replaces the map of default codecs with public static final CodecInfo constants for each codec.
* Modifies the ShadowMediaCodecConfig constructor to accept a set of CodecImpls instead of mime types.
* Updates factory methods to reflect the constructor change.
* Updates addSupportedMimeTypes to addDecoder, taking a CodecInfo instead of a mimeType.
This is a non-functional change.

We currently assume SW codecs are capable of playing all resolutions
and frame rates up to their declared supported maximum values, even
though the are likely not able to keep up playback smoothly for higher
resolutions. For HW codecs we can check PerformancePoints to declare
them as EXCEEDS_CAPABILITIES if they technically support a format but
are not performant enough. We can do the same for SW codecs by
checking getAchievableFrameRatesFor.
