The following was happening:
- VideoFrameRenderControl.render() was calling
VideoFrameReleaseAction.getFrameReleaseAction().
- VideoFrameReleaseAction.getFrameReleaseAction() was calling
FrameTimingEvaluator.shouldIgnoreFrame(), which is implemented in
MediaCodecVideoRenderer.
- MediaCodecVideoRenderer.shouldIgnoreFrame(), when returning true,
was also flushing the VideoSink, which was flushing the
VideoFrameRenderControl.
- VideoFrameRenderControl.render() was removing the frame from the
presentationTimestampsUs queue, but the frame had already been removed
by the flush operation, causing an exception to be thrown.
This fix removes the last step.

To do this, refactor stream start position handling so that
VideoFrameRenderControl is only passed a start position when it should
be applied, and therefore doesn't need to take a timestamp associated
with each start position anymore

From [ the last change in `DefaultPreloadManagerTest`](2b54b1ebbe), the preloadManager began to use a separate `preloadThread` in `release_returnZeroCount_sourcesAndRendererCapabilitiesListReleased`, which unveils a bug in `PreloadMediaSource`. When `PreloadMediaSource.releasePreloadMediaSource` is called, `preloadHandler` will post a `Runnable` on the preload looper to release the internal resources. Before this `Runnable` is executed, it is possible that the [`stopPreloading`](https://github.com/androidx/media/blob/main/libraries/exoplayer/src/main/java/androidx/media3/exoplayer/source/preload/PreloadMediaSource.java#L442) method is executed just as the result of preloading has completed. This is expected to remove the posted `Runnable`s for further preloading, however, the posted `Runnable` for releasing will also be removed from the message queue.
Ideally we should use `postDelayed(runnable, token, delayMillis)` to post the runnables so that the token will be useful to identify which messages to remove in `removeCallbacksAndMessages(token)`, but that `postDelayed` method is only available from API 28. So in this change we are using a separate handler for releasing, and then the call of `preloadHandler.removeCallbacksAndMessages` won't impact the runnable for releasing.

The new callback allows an app to read data from the content
timeline to populate the `AdPlaybackState`. To avoid a deadlock
between the `AdMediaSource` waiting for the `AdPlaybackState` and
the app waiting for the content `Timeline`, a boolean flag
`useLazyContentSourcePreparation` is introduced to tell the
`AdsMediaSource` to prepare the content source immediately
to make the `Timeline` available.
A unit test verifies that in none of the cases (lazy preparation or
immediate preparation) a `Timeline` without ad data is leaked to the
caller. This ensures that in the case of a preroll, the player won't
initially and accidentally read content media data before starting to
load the preroll ad. While the content source is prepared early, no
content media period must be created before the preroll starts.

Implemented `getCachedDuration()` to provide an estimate of cached data in memory and `hasCacheReachedEndOfStream()` to indicate if the cache has reached the end of the stream.
Note: The Javadoc for the newly added methods closely follows that of the platform `MediaExtractor`. While the current implementation always uses a cache and therefore never returns `-1` from `getCachedDuration`, this leaves room for future changes should caching behavior or conditions evolve.

The `RendererCapabilities` and `TrackSelector` objects are accessed on the preload thread during the preloading, when releasing them, they need to be released on the same thread. Otherwise, it is possible that they have already released on the application thread, while the PreloadMediaSource still tries to access them on the preload thread before the source is released.

The test has been moved to an instrumentation test as it relies on APIs that vary by SDK version. Robolectric’s emulation lacks sufficient realism in some cases, which impacts test accuracy.

Restructured sample metadata management in `MediaExtractorCompat` to maintain a queue of `SampleMetadata` objects, each containing `timeUs`, `flags`, `size`, and `trackIndex`, rather than storing only track indices.
Introduced a pooling mechanism for `SampleMetadata` to reduce object allocation and improve memory efficiency. The new `SampleMetaDataQueue` centralizes metadata for easier access and management, eliminating the need to allocate a buffer or peek into the `SampleQueue` to retrieve sample metadata.
This change does not change existing behavior, it optimizes the internal structure, and existing tests already verify the relevant APIs.

If audio processors report a drifting position, we currently update
the media position parameters to correct this drift. However, this
means we pass in the wrong value to
audioProcessorChain.getMediaDuration, which reuqires the time since
the last flush.
To fix this problem, we can instead save the drift seperately and
apply it where needed.

Previously, `getTrackFormat()` in `MediaExtractorCompat` returned a `MediaFormat` without setting `MediaFormat.KEY_DURATION`. With this change:
- `MediaFormat.KEY_DURATION` is set based on the track's duration, if available.
- If the track duration is unset, the duration from the seek map is used as a fallback.
- When neither duration is set, `MediaFormat.KEY_DURATION` remains unset.
This ensures that `MediaFormat.KEY_DURATION` is populated when possible, enhancing duration information availability.

When transitioning to the next media position parameter checkpoint
we estimate the position because the audio processor chain no longer
provides access to the actual playout duration.
The estimate using the declared speed and the last checkpoint may
have drifted over time, so we currently estimate relative to the
next checkpoint, which is closer and presumably provides a better
estimate. However, this assumes that these checkpoint are perfectly
aligned without any position jumps.
The current approach has two issues:
- The next checkpoint may include a position jump by design, e.g.
if it was set for a new item in the playlist and the duration of
the current item wasn't perfectly accurate.
- The sudden switch between two estimation methods may cause a jump
in the output position, which is visible when we add new media
position checkpoints to the queue, not when we actually reach the
playback position of the checkpoint.
We can fix both issues by taking a slightly different approach:
- Continuously monitor the estimate using the current checkpoint. If
it starts drifting, we can adjust it directly. This way the estimate
is always aligned with the actual position.
- The change above means we can safely switch to using the estimate
based on the previous checkpoint. This way we don't have to make
assumptions about the next checkpoint and any position jumps will
only happen when we actually reach this checkpoint (which is more
what a user expects to see, e.g. at a playlist item transition).

Added start and end time details to the error message for `REASON_START_EXCEEDS_END`, helping to debug cases where the start time exceeds the end time.
PiperOrigin-RevId: 688117440
Before this change:
* With legacy subtitle decoding (at render time), load errors (e.g. HTTP
404) would result playback completely failing, while parse errors
(e.g. invalid WebVTT data) would be silently ignored, so playback
would continue without subtitles.
* With new subtitle decoding (at extraction time), both load and parse
errors would result in playback completely failing.
This change means that now neither load nor parse errors in text or
metadata tracks stop playback from continuing. Instead the error'd track
is disabled until the end of the current period.
With new subtitle decoding, both load and parse errors happen during
loading/extraction, and so are emitted to the app via
`MediaSourceEventListener.onLoadError` and
`AnalyticsListener.onLoadError`. With legacy subtitle decoding, only
load errors are emitted via these listeners and parsing errors continue
to be silently ignored.

These events are always reported with the primary child period ID,
because this is the same ID used in the parent `MergingMediaSource`'s
Timeline.
This ensures that e.g. loading errors from sideloaded subtitles (which
uses `MergingMediaSource`) are now reported via
`AnalyticsListener.onLoadError`.
It results in non-error events being reported from these children too,
which will result in more `onLoadStarted` and `onLoadCompleted` events
being reported (one for each child).

When a `SampleQueue` is prepared prior to playback, the start position may be less than the timestamp of the first sample in the queue and still be valid. This scenario can come about with specific clipping values and if all samples are sync samples. Currently, with `ClippingMediaPeriods` around `ProgressiveMediaPeriods`, if the `SampleQueue` has already been reset through the seekTo operation in `onPrepared`, then in the aforementioned scenario the seekTo operation in `handleDiscontinuity` will remove all samples and reset the loading periods unnecessarily.
The solution is that if the `ProgressiveMediaPeriod` has already handled a seekTo operation for the same position and the sample queue has not been read yet, then loading does not need to be reset.
The tests in `MergingPlaylistPlaybackTest` were specifically causing this behavior through its setup of `MergingMediaSources` around clipped `FilteringMediaSources`. Since the video content was not 'all sync samples', there would always be a discontinuity to handle and the audio content being 'all sync samples' would start with samples post start time.
These changes also remove the flakiness from the `MergingPlaylistPlaybackTest`.

This refactors the `supportsFormat` method on the MediaCodecVideoRenderer to be a static method that can be called from external components to determine if a video format is supported by the device renderers. Since `context` is the only component that is part of the MCVR, it can easily be obtained externally and passed to the method.
This can help optimize format support decisions ahead of time of a player having been instantiated, such as removing unsupported representations from a dash manifest.
This could also be done for the MCAR but would also require passing in the AudioSink and isn't required at this time.
