278eaf47ad Add log session ID APIs to MediaExtractorCompat
Implemented `setLogSessionId(LogSessionId)` and `getLogSessionId()` methods.

Note: The `LogSessionId` is currently **not** forwarded to `MediaParser`, but this will be addressed once `MediaParser` can be used to configure `MediaExtractorCompat`.

261ca326c5 Move MediaExtractorCompatTest from test/ to androidTest/
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. By using an instrumentation test, we ensure that the tests run in a real Android environment, providing reliable results for SDK-dependent APIs.

Before this change when ExoPlayer is configured with setVideoEffects
and no display surface, codecs that need Set Output Surface Workaround
would not be initialized because hasSurfaceForCodec always returns false

d8ad18383d Optimize sample metadata handling in MediaExtractorCompat
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.

06718c5df3 Fix position tracking bug for inaccurate audio processors
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.

df07fa35d8 Populate MediaFormat.KEY_DURATION in MediaExtractorCompat
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.

7c0cffdca8 Improve position estimate when transitioning to another checkpoint
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).

49dec5db8b Ignore renderer errors from text/metadata tracks
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.

191bc094a5 Propagate events from secondary children in MergingMediaSource
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).

2a1e71b203 Reduce needless loading period resets in clipping mediasource playlists
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`.

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.

f7af58951d Allow signed TTML region origins
The origin may be negative if the subtitle starts off-screen
but extends into the screen for example.

TTML1 defines `tts:origin` in terms of
[`length`](https://www.w3.org/TR/2018/REC-ttml1-20181108/#style-value-length),
which allows a prefix of `+`, `-` or nothing, and it's the
[same in TTML2](https://www.w3.org/TR/2018/REC-ttml2-20181108/#style-value-length).

4481b3567e Add workaround for codecs not propagating EOS signal.
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.

138a8d65ca Get updated buffered position when calling shouldStartPlayback
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.

2dde824bde Fix the flakiness in DefaultPreloadManagerTest
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.

5879426c07 Check surface validity before configuring it on a codec
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.

ba1cdba403 Preload first period of next window
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.

5e3dcea1bf Ramp up volume after AudioTrack flush to avoid pop sound
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).

0b86f89498 Guard DrmSession.requiresSecureDecoder calls with state checks
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.
