Earlier watchdog timer was started only after all the tracks are
added. For the cases where export is stuck before adding tracks,
the export would hang forever and will not timeout automatically.
With the changes, watchdog timer is started as soon as export is
started/resumed. Now if the pipeline is stuck before writing any samples,
it will timeout and report error to the caller.
Existing test case: c35a9d62ba/libraries/transformer/src/test/java/androidx/media3/transformer/MediaItemExportTest.java (L996)

The behaviour was changed in 1.4.0 with 0f42dd4752,
so that the buffer timestamp is compared to `outputStartTimeUs` when
deciding whether to discard a "decode only" buffer before decoding
(instead of the deprecated/removed `isDecodeOnly` property). This breaks
when the buffer timestamp is `TIME_END_OF_SOURCE` (which is
`Long.MIN_VALUE`), because `TIME_END_OF_SOURCE < outputStartTimeUs` is
always true, so the end-of-stream buffer is never passed to the decoder
and on to `TextRenderer` where it is used to
[set `inputStreamEnded = true`](40f187e4b4/libraries/exoplayer/src/main/java/androidx/media3/exoplayer/text/TextRenderer.java (L434-L436))
and so playback hangs.

PiperOrigin-RevId: 695767247
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.

A skeleton implementation that doesn't actually return decoded frames.
In the current state, we use ExoPlayer to seek to a position, and
ExoPlayer.setVideoEffects to record the presentation time selected.
Seeking and processing frames are synchronized via ListenableFuture
callbacks.

In some cases, callers will need to pass in both BitmapLoader and Codec.DecoderFactory without specifying a custom MediaSource.Factory. Omitting the annotation will result in NULL_FOR_NONNULL_TYPE compilation errors in Kotlin.

This is because the method is called for each media item, the current name
implies that the method is only called once for all videos in a sequence.

This method will replace the current estimation mechanism in place on
`getSpeedAdjustedTimeAsync()`, which relies on heuristics from previous
output rates and depends on the state of the `AudioProcessor`. The new
static method should be considerably more accurate.

This ensures it works correctly when there are multiple SEI messages per
sample and the max size is set from e.g. H.264's
`max_num_reorder_frames`.

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.

Note: `androidx.media3.common.DrmInitData` is returned instead of the platform `android.media.DrmInitData` because the platform class has a package-private constructor, making it impossible to implement the abstract class outside the platform.

Added the functionality for `Choose local file` button to be able to go and select a local file from the device. The file was then displayed by using ExoPlayer inside PlayerView.
PiperOrigin-RevId: 693756565
Added a basic UI to the effect demo app, including a PlayerView, buttons to choose preset input and choose local file, and a button to apply effects. The buttons are currently not implemented, and the app will show a snackbar message when they are clicked.

Changed the dependency of `lib-common` in `lib-ui` from an `implementation` dependency to an `api` dependency. This change ensures that classes and interfaces from `lib-common` used in the public API of `lib-ui` are correctly exposed to consumers of `lib-ui`.
For example, `PlayerView implements AdViewProvider` where the latter is from `androidx.media3.common.AdViewProvider`.

Enable transformer to transmux into alternative sample MIME types.
For example, some Dolby Vision profiles have a backwards-compatible
AVC or HEVC layer. MV-HEVC is backwards compatible with HEVC.
This change enables Transformer to transmux into the backwards compatible
format to improve compatibility with legacy APIs such as
MediaMetadataRetriever.

All instances of PlaybackVideoGraphWrapper use the same
VIDEO_FRAME_PROCESSOR_FACTORY_SUPPLIER which uses the same
DefaultGlObjectsProvider.
Each call to DefaultGlObjectsProvider.release() releases
all previously created EGLContexts.
Lazily create a new DefaultGlObjectsProvider for each
DefaultVideoFrameProcessor (not one per factory).

The tests became more flaky after 76e4abe428, likely because playback
was able to start slightly earlier, exaggerating any existing race
conditions. Fix the flakiness by letting all tests with subtitle
parsing wait until all data is fully loaded before starting to play.

When a new media session sets media button preferences, we need to
"translate" them back to a custom layout to ensure the user preferences
are represented as closely as possible when the controller uses the
old button placement rules.

The method currently modifies the input Bundle, but it's easier to
reason about it if the method is side-effect free and the places
that need to modify a Bundle do this after calling the method.
PiperOrigin-RevId: 693288031
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`.

* Provide a helper Composable for remembering the state instance and launching the listening coroutine that observes the changes in the Player
* Add an example to demo-compose of using Shuffle- and Repeat- ButtonStates inside a Shuffle- and RepeatButton Composable.
* Reformat the MainActivity usage of `Shuffle` and `Repeat` buttons to form extra Player Controls and combine Prev/Play-Pause/Next with Shuffle/Repeat (Minimal controls + Extra controls = `PlayerControls`)

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.
PiperOrigin-RevId: 692933259
Also move the `lint.xml` config which disables the `NewApi` check from
`lib-session` to the existing top-level file, and limit it to cover all
Robolectric tests by path matching.

This change keeps getSurfaceForCodec and hasSurfaceForCodec in sync.
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
PiperOrigin-RevId: 692900899
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.

This CL adds utility methods to obtain sample-aligned timestamps from a
`SpeedProvider` to solve in a unified way the issues arising from
conversions between sample positions and microseconds.
The new utility methods will also help with the implementation of a
static method like `getDurationAfterProcessorApplied()` that will remove
the need for thread synchronization between the video and audio pipeline
for speed changing effects.

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.

Also makes muxer shift the first video timestamp to zero, if it's not.
The trim position should respect the media timeline.
For example in a video that is 10s long (without edit list), if an edit list
adds 1_000ms to each video sample, and trimming 100ms, here's the expected:
- The video duration is 10.9s (`10s + 1s edit - 0.1s trim`)
- The first video frame time would be at 0.9s (`1s edit - 0.1s trim`)
