This controller connects the audio output to the MediaCodec so
that it can automatically propagate CTA-2075 loudness metadata.

This replaces the existing PlaceholderSurface mode with a more
efficient solution that doesn't require a GL texture or a new

This is a regression test for the bug introduced in bb9ff30c3a
which was manually spotted and fixed in 0d2bf49d6a.
Reverting the fix causes this test to fail.
This test is a bit hacky because we have to munge the stack trace of
the `IllegalStateException` to make it look like it was thrown from
inside `MediaCodec`. We deliberately do this 'badly' (e.g. using
`fakeMethod`) to avoid a future reader being confused by a
fake-but-plausible stack trace.

Now the value is guaranteed to be zero (see bb9ff30c3a), we can
remove the rotation handling for it in the UI module. We can also
enforce the documentation more clearly by not even setting the
value to anything other than zero.

Added a method to set the timeout for the SNTP request.
Also changed the default timeout to 5s instead of 10s as it seemed quite high.

The change in bb9ff30c3a removed the detection util completely,
but even on API21+, the codec exceptions can be thrown as
IllegalStateException and we should reinstate this check to
correctly classify the exceptions.

This removes several workarounds that are no longer needed, including
`codecNeedsMonoChannelCountWorkaround` which has been permanently
disabled since the (incomplete) minSdk 19 clean-up in fb7438378d.

This should have no influence on app behavior and other policies
and just allows code to depend on new API 35 platform symbols.

We currently use displaySurface == placeholderSurface IF codec != null
as a signal that the codec is configured with a placeholder. In the
future, this placeholder might not be needed and we can decouple this
state a bit better by leaving displaySurface == null in this case and
only using placeholderSurface instead of null when setting a Surface
to the codec.

All other AndroidX libraries have already increased their min SDK to
21.
This change renames private symbols to remove `V21` suffixes and
similar, but doesn't change public or protected symbols with similar
names, to avoid needless breakages/churn on users of the library.
Some of the dead code removal is more complex, so I've split it out
into follow-up changes to make it easier to review.

MediaCodecRenderer might not be able to determine whether a sample
is last in time. Do not use decoder input skipping optimization
for buffers close to media end duration in order to ensure
last frame is rendered.

The integration with `SubtitleTranscodingExtractorOutput` has been

VideoSink.registerInputFrame is now called for every input frame (not
only the ones that should be rendered to the input surface) because it's
the VideoSink that decides whether it wants the frame to be rendered.

In order for DASH playback to benefit from
FLAG_READ_WITHIN_GOP_SAMPLE_DEPENDENCIES, the fMP4 extractor flag
must be set. The smallest API change that allows this is to add an
experimental method to BundledChunkExtractor.
Add a dash end-to-end test to verify that video frames are skipped at
decoder input.

The operation almost always acquires resources straight-away,
for example a new thread or file access. This means starting
many metadata retrievals in parallel easily causes resource
contention. This problem can be alleviated by limiting the
maximum number of parallel retrievals.
Local testing showed a 20% speedup for local file retrievals
when limited to 5 in parallel. Any more parallel retrievals
did not show any improvement or started getting slower again
the more operations are allowed.
PiperOrigin-RevId: 650674685
MetadataRetriever is often used in a loop to retrieve data about many
items in a directory for example. In such cases, it's wasteful to
start a new 'playback' thread for each retrieval, in particular since
this thread is doing almost nothing (just triggering loads and handling
events). This change re-uses an existing thread if one exists already.

During a seek, or when playing a media with clipped start,
MCVR encounters preroll decode-only buffers that are not rendered.
Use C.BUFFER_FLAG_NO_OTHER_SAMPLE_DEPENDS_ON_THIS to determine
whether a decode-only buffer is unused as reference.
These buffers can be dropped before the decoder.
When this optimization is triggered, increment
decoderCounters.skippedInputBufferCount.
Tested in ExoPlayer demo app on "One hour frame counter (MP4)"
after enabling extractorsFactory.setMp4ExtractorFlags(
FLAG_READ_WITHIN_GOP_SAMPLE_DEPENDENCIES);
Observe: "sib" increases on each seek.

The idea was to not even write any samples to SampleQueues as
they are not needed during the metadata extraction process.
However, this is not easily possible as long as we use our
existing Extractors and MediaSource/Periods for loading given
how deeply ingrained the extraction of samples is in these
classes. For most common formats like MP4, no samples will be
extracted anyway as they can finish the prepare step without
reading any samples.

Upon the call of `PreloadMediaSource.preload`, the source will periodically check the source refresh or period loading error, and trigger `PreloadMediaSource.PreloadControl.onPreloadError`. For now, the `DefaultPreloadManager` will skip the problematic source and continue to preload the next source. The checking of the error will be terminated when the source stops preloading or releases.

The percentage should be interpreted as relative to the size of a parent
node.
This change makes this inheritance work correctly for percentages in
both the parent and child. It does not fix the case of a non-percentage
parent size with a percentage child size.

The VideoSink has an input and an output surface. Clarify which surface
the Javadoc is referring to. Also document that the VideoSink can be fed
with images, and that multiple renderers can feed the same sink.

MCVR crashed because MCVR registers a new input stream to VideoSink on every
`onOutputFormatChanged()`, assuming that `onOutputFormatChanged()` is only
invoked on media item transition. However, it can be called multiple times for
one media item.

Upon track transition of offloaded playback of gapless tracks, the framework will reset the audiotrack frame position. The `AudioTrackPositionTracker`'s `AudioTimestampPoller` must be made to expect the reset and cache accumulated sum of `AudioTimestamp.framePosition`.

When handling a playback error that originates from a future item in
the playlist, we added support for jumping to that item first,
ensuring the errors 'happen' for the right 'current item'.
See 79b688ef30.
However, when we add this new position discontinuity to the
playback state, there may already be other position discontinuities
pending from other parts of the code that executed before the
error. As we can't control that in this case (because it's part
of a generic try/catch block), we need to send any pending
updates first before handling the new change.

Setting a `null` value doesn't remove the key as expected per the `MediaFormat` API documentation, using the `removeKey` method instead which is only available starting API level 29.

ExoPlayer used to call `stop()` before `release()`. This was removed in
<unknown commit>.
A framework bug introduced in Android 11 (API 30) resulted in some
DRM -> clear transitions failing during `MediaCodec.configure()`. An
investigation in Issue: google/ExoPlayer#8696 and b/191966399 identified that this was
due to `release()` returning 'too early' and the subsequent
`configure()` call was then trying to re-use a `Surface` that hadn't
been fully detached from the previous codec. This was fixed in
Android 13 (API 33) with http://r.android.com/2094347.
ExoPlayer worked around the framework bug by adding an arbitrary 50ms
sleep after a failed codec initialization, followed by retrying. This
was enough to resolve the problem in the test scenario on a OnePlus
AC2003.
Issue: androidx/media#1497 points out that 50ms might not be the appropriate delay
for all devices, so it's an incomplete fix. They suggested re-adding the
`MediaCodec.stop()` call instead. This also reliably resolves the issue
on the OnePlus AC2003 (with neither workaround in place, the problem
repros almost immediately).

Extractors should not report additional tracks once they called
ExtractorOutput.endTracks. This causes thread safety issues in
ProgressiveMediaPeriod where the array of sample queues is
extended while the playback thread accesses the arrays.
Detecting this problem early is beneficial to avoid unexplained
exceptions later one. In most cases where this may happen (namely
TS extractors finding new tracks), it's better to ignore the new
tracks instead of failing completely. So this change adds a
warning log message and assigns a placeholder output.
Note: The same workaround already exists in HlsSampleStreamWrapper
and MediaExtractorCompat.
