The `DefaultPreloadManager.Builder` is able to build the `DefaultPreloadManager` and `ExoPlayer` instances with the consistently shared configurations. Apps can:
* Simply setup the `DefaultPreloadManager` and `ExoPlayer` with all default configurations via `build()` and `buildExoPlayer()`;
* Or customize the shared configurations by the setters on `DefaultPreloadManager.Builder` and setup via `build()` and `buildExoPlayer()`;
* Or customize the player-only configurations for `ExoPlayer` via `buildExoPlayer(ExoPlayer.Builder)`.

- Updated `DefaultTrackSelector.SpatializerWrapperV32.canBeSpatialized` to handle IAMF format.
- Modified `isAudioFormatWithinAudioChannelCountConstraints` to check for `NO_VALUE` of `channelCount` to improve readability.
Note: `DefaultTrackSelector.SpatializerWrapperV32.canBeSpatialized` is not triggered for the IAMF format due to the unset channel count (`Format.NO_VALUE`). The update ensures completeness.

Object-based audio is more efficient and flexible than channel-based audio, supporting a broader range of devices. This update makes `DefaultTrackSelector` prefer object-based audio when other factors are equal, ensuring its use whenever possible.

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.
PlaybackVideoGraphWrapper will soon contain an input and an output video
sink, as the rendering of the VideoGraph output frames will be handled
by a DefaultVideoSink instance.

If a codec received the EOS signal and already returned the last
output buffer, we should expect the output EOS very quickly. If
it doesn't arrive within 100ms, we can proceed to end the stream
manually without waiting any further to prevent cases where the
codec is completely stuck otherwise.

The buffered position was last updated before the beginning of
the renderer loop in doSomeWork. As the loading happens on a
background thread, it may have progressed further already
depending on how long it took to run the renderer loop.
It's slightly more correct to pass in an updated value to
shouldStartPlayback so that playback can start quicker if the
buffering is particularly fast.

We began to use a different preload thread than the main thread in the `DefaultPreloadManagerTest`, then in the test execution, we should also ensure that the events queued on the preload looper have been executed.
Also, there is an edge case also causing flakiness. Assume that `DefaultPreloadManager` is preloading source B, then the app invalidates and triggers another sequence of preloading, say they are A, B and C. There is possibility that source B finishes preloading (started before `invalidate`) when A starting to preload, then `onPreloadSkipped` will be triggered for source B instead of `onPreloadCompleted`. However, the functional block inside of `onPreloadSkipped` is dispatched asynchronously, and by then it's possible that B starts to preload again at the consequence of A being completed, then the functional block just mentioned may think that the current source matches at B, and will advance the current preloading source to C, without informing the `Listener.onPreloadCompleted` for it. As the result, the `Listener.onPreloadCompleted` can never be triggered for B for the second sequence. To fix this, we should prevent the functional block in `onPreloadCompleted`, `onPreloadError`, `onPreloadSkipped` to be even dispatched, when the source doesn't match the current preloading one.

This check is also done when setting a surface on ExoPlayerImpl,
but by the time we configure the codec the surface may have become
invalid (e.g. when it is destroyed). Even though we immediately remove
a destroyed surface, we could still accidentally use it before the
removal is processed. To avoid these edge cases, we can simply not
configure the codec with an invalid surface.

Allow apps to preload the first period of the next window in
the playlist of `ExoPlayer`. By default playlist preloading is
disabled. To enable preloading,
`ExoPlayer.setPreloadConfiguration(PreloadConfiguration)` can be
called.
`LoadControl` determines when to preload with its implemenation of `shouldContinuePreloading(timeline, mediaPeriodId, bufferedDurationUs)`.
The implementation in `DefaultLoadControl` allows preloading only when
the player isn't currently loading for playback. Apps can override this
behaviour.

AudioTrack doesn't automatically ramp up the volume after a flush
(only when resuming with play after a pause), which causes audible
pop sounds in most cases. The issue can be avoided by manually
applying a short 20ms volume ramp, the same duration used by the
platform for the automatic volume ramping where available.
Together with the already submitted 6147050b90, this fixes the
unwanted pop sounds for most cases in the desired way. It only
leaves two cases that are not handled perfectly:
- If the media file itself contains a volume ramp at the beginning,
we wouldn't need this additional ramping. Given the extremely
short duration, this seems ignorable and we can treat it as a
future feature request to mark the beginning of media in a special
way that can then disable the volume ramping.
- For seamless period transitions where we keep using the same
AudioTrack, we may still get a pop sound at the transition. To
solve this, we'd need a dedicated audio processor to either ramp
the end of media down and the beginning of the next item up, or
apply a very short cross-fade. Either way, we need new signalling
to identify cases where the media originates from the same source
and this effect should not be applied (e.g. when re-concatenating
clipped audio snippets from the same file).

This method is documented that it may only be called in `STATE_OPENED`
or `STATE_OPENED_WITH_KEYS`. It's possible for it to be called in other
states (like `STATE_ERROR`) without this guard.
Previously this didn't cause issues, but since 9d62845c45
we assume that the `sessionId` is non-null in this method, which results
in an `IllegalStateException` when the documented state restriction is
ignored.

The Galaxy Tab S7 FE has a device issue that causes 60fps secure H264 streams to be marked as unsupported. This CL adds a workaround for this issue by checking the CDD required support for secure H264 in addition to the current check on standard H264. If the provided performance points do not cover the CDD requirement of support 720p H264 at 60fps, then it falls back to using legacy methods for checking frame rate and resolution support.

Previously, track IDs were added to `trackIndicesPerSampleInQueuedOrder`
even when the sample was not committed. This caused issues where attempts
to read samples from the `SampleQueue` returned `C.RESULT_READ_NOTHING`,
which led to an exception being thrown due to the assumption that samples
were available to read.
This fix updates the logic to track sample commits by comparing the write index before and after calling `SampleQueue.sampleMetadata`. Track indices are only added if the sample was committed, ensuring accurate sample handling and avoiding exceptions.

`PreloadMediaSource` allows to have a `startPositionUs` passed when `preload` is called, then in `PreloadControl.onContinueLoadingRequested`, it can be more intuitive to see the buffered duration rather than the absolute buffered position as the preload progress. Similar in `DefaultPreloadManager`, we haven't allowed the apps to set a custom start position for individual sources though, once we add this support, using the "duration from the start position" than the absolute position will be less error-prone, otherwise, it can run into a case that the position that the apps set is smaller than the start position.

When processing edit lists in MP4 files, the media start position may be a non-keyframe. To ensure proper playback, the decoder must preroll to the preceding keyframe, as these preroll samples are essential for decoding but are not rendered.
