This implicitly fixes a bug by removing the buggy implementation in H265Reader in favour of a working one. This change also adds tests to confirm the parsing bug is fixed.
`prepare()` now logs a warning if it's called before `setPlayer()`
because it's not possible to tell if it's being called on the wrong
thread (since 3480a27994).
This change finds all the places one is called immediately after the
other and flips the order to be more correct.

`findDecoder/EncoderForFormat` seem to be more restrictive than querying

In `ExternalTextureManager` in seemingly rare cases end of stream is signaled
at the point where a frame is currently pending processing. In that case the
video end of stream signal was lost. If the muxer timeout was enabled this

get stuck
Add code to signal end of stream in `onInputFrameProcessed` as well, so that we
signal end of stream when the pending frame is handled.

The overrides specified by a MediaController may not use the exact
same TrackGroup instances as known to the Player because the groups
have been bundled to and from the controller. This bundling may
alter the instance slightly depending on the version used on each
side of the communication and the fields set (e.g. Format.metadata
is not supported for bundling).
This issue can be solved by creating unique track group ids for
each group on the session side before bundling. On the way back,
the groups in the track selection parameters can be mapped backed
to their original instances based on this id.

Previously `ChannelMixingAudioProcessor` output float because it was
implemented using the audio mixer's float mixing support.
Move the implementation over to just using the `ChannelMixingMatrix` and make
it publicly visible in the common module so it can be used by apps for both
playback and export.
Also resolve a TODO that no longer had a bug attached by implementing support
for putting multiple mixing matrices to handle different input audio channel
counts, and fix some nits in the test code.
Tested via unit tests and manually configuring a `ChannelMixingAudioProcessor`
in the transformer demo app and playing an audio stream that identifies
channels, and verifying that they are remapped as expected.

This change selects the best suited media button receiver
component and pending intent when creating the legacy
session. This is important to ensure that a service can
be started with a media button event from BT headsets
after the app has been terminated.
The `MediaSessionLegacyStub` selects the best suited
receiver to be passed to the `MediaSessionCompat`
constructor.
1. When the app has declared a broadcast receiver for
`ACTION_MEDIA_BUTTON` in the manifest, this broadcast
receiver is used.
2. When the session is housed in a service, the service
component is used as a fallback.
3. As a last resort a receiver is created at runtime.
When the `MediaSessionLegacyStub` is released, the media
button receiver is removed unless the app has provided a
media button receiver in the manifest. In this case we
assume the app supports resuming when the BT play intent
arrives at `MediaSessionService.onStartCommand`.

PiperOrigin-RevId: 523456840
In addition to the changes in 3a5c4277a7
This change essentially reverts 30e5bc9837 (Merged Jul 2022).
From this CL on, `VideoFrameProcessor` takes in non-offset, monotonically
increasing timestamps. For example, with one 5s and one 10s video,
- `VideoFrameProcessor`'s input should start from 0
- On switching to the second video (10s), the timestamp of the first frame in
the second video should be at 5s.
In ExoPlayer however, `streamOffset` is managed differently and thus needs
correction before sending the frames to `VideoFrameProcessor`:
- The timestamp of the first video is offset by a large int, so the first frame
of the first media item has timestamp (assuming) 10000000000000000
- The last frame of the first media item has 10000005000000000
- At this point the stream off set is updated to 10000005000000000
- The pts of the first frame of the second video starts from 0 again.
PiperOrigin-RevId: 523444236
Simplify the audio encoder input timestamp calculation. The new calculation
avoids drifting by tracking the total number of bytes encoded rather than
tracking the timestamp and remainder separately, and also makes the timestamps
match the decoder output buffer timestamps.
Also switch one of the export tests that was passing through AMR samples over
to using WAVE audio. The problem with using AMR is that the compressed samples
are not necessarily an integer number of audio frames and the shadow decoder
would pass them from input to output, so the audio encoder was receiving
non-integer numbers of audio frames.
Tested by logging the timestamps at the decoder output and encoder input with
forcing transcoding audio, and verifying that after this change the audio
timestamps are no longer off by one.
PiperOrigin-RevId: 523409869
The video asset loader renders decoder output to a surface texture, and if the
video sample pipeline is in the process of updating the surface texture image
at the moment when the asset loader video decoder is released this seems to
cause `MediaCodec.release` to get stuck.
Swap the release order so that we stop updating the texture before trying to
release the codec.
PiperOrigin-RevId: 523401619
Log at debug level immediately when MediaCodec throws. This logging will be
output closer to the time when the error actually happened so should make it
easier to identify the order of components failing.
Downgrade logging of errors after export ends to warning level, as output may
still be fine if there was a problem after exporting completed (though it's
still worth logging a warning as the device may not be in a good state).
PiperOrigin-RevId: 523370457
Before this CL, SurfaceTexture.onFrameAvailable was used to tell whether a frame
was available in the VideoFrameProcessor's output texture. This was incorrect, as
it would rely on having the texture be written to before the
SurfaceTexture.onFrameAvailableListener is invoked, leading to null-pointer-
exceptions on timeouts.
Instead of using DefaultVideoFrameProcessor different interfaces to set that we
want to output to a texture, and get that output texture, use one interface that
sets a listener, and renders to a texture iff that listener is set. As this
listener is executed on the GL thread, this also allows us to no longer need to
expand visibility for the GL task executor and tasks.

There is a race with the ad period preparation having completed
and `onDownstreamFormatChanged` being called when a live stream
is joined in an ad period. In this case the stream event metadata
of the period is immediately emitted and causing an ad media period

being prepared (1 out of 4).
Using an `isPrepared` flag makes sure we don't hand out the media
period to early in `getMediaPeriodForEvent`.

This includes:
- Add an ad for each LOADED event of the SDK by taking the duration
of the ad from the media structure to exactly match the start position
of ads and then use `addLiveAdBreak()` that is used for HLS live already.
- When the refreshed content timeline arrives, possibly correct
the duration of an ad that has been inserted while the period duration was
still unknown (last period of the live timeline).
- When an ad period is removed the ad group needs to be put into a condition
that allows continuing playback.

Handling of the stream offset and start position was unnecessarily
complex and even incorrect. It was going to be an issue for
concatenation of video and image input.
The stream offset is the offset added before decoding/encoding to
make sure it doesn’t fail in case of negative timestamps (which do
rarely occur).
The start position is equal to the stream offset, plus the clipping
start time if the media is clipped.
Before this change:
- Samples were offset by the start position before decoding, and this
offset was removed before muxing.
- The startPosition of the first MediaItem in a sequence was used for
all the MediaItems in this sequence (which is incorrect).
- The stream offset was removed before applying the GL effects and
added back before encoding so that it was not visible to the OpenGL
processing.
After this change:
- The start position is subtracted in the AssetLoader, so that the
downstream components don’t have to deal with the stream offsets and
start positions.
- Decoded samples with negative timestamps are not passed to the
SamplePipelines. The MediaMuxer doesn’t handle negative timestamps
well. If a stream is 10 secondes long and starts at timestamp -2
seconds, the output will only contain the samples corresponding to the
first 8 (10 - 2) seconds. It won’t contain the last 2 seconds of the
stream. It seems acceptable to remove the first 2 seconds instead.

The `DashMediaSource` wrongly added an offset to the media times set
to the `MediaLoadData`. With this the `startTimeMS` and `endTimeMs`
don't represent the positions in the period but in the stream.
`DashMediaSource` was the only call site that was setting the offset
to a non-zero value. So if we are using 0 for the `DashMediaSource`
as well, the offset is redundant and we can remove it everywhere.

Previously, we always used ImageReader to read from the output of DefaultVideoFrameProcessor, for pixel tests. This has a limitation of not being
able to read HDR contents, so that we couldn't support HDR pixel tests.
Reading from a texture allows us to use glReadPixels to read from
DefaultVideoFrameProcessor, and build upon this to implement HDR pixel tests. We do
still want tests for surface output though, because real use-cases only will output
to Surfaces.
Also, add some tests for outputting to textures, since this test infrastructure is
a bit complex.

When MediaCodecRenderer is given an empty sample stream, it puts
its output format change tracking in a bad state where we never
process future stream changes because we are waiting for a sample
that doesn't exist.
We can fix this by:
- Looping the pending output stream changes to see if we processed
more than one change at once (this fixes the tracking for empty
sample streams that are not the first in the queue).
- Checking if none of the previous streams queued any samples in
onStreamChanged to handle this in the same way as the case
where we already output all samples (this fixes the problem when
the empty sample stream comes first in the queue).
- Also calling onProcessedStreamChange for the case above, which
was missing previously.

This change does basically three things in preparation of a follow
up CL that will insert ad breaks into multi-period live windows.
- Make sure that only `AdPlaybackState`s of multi-period streams
are passed to `ImaUtil.splitAdPlaybackStateForPeriods()` from
the media source.
- Enhance the splitting algorithm in ImaUtil to support live windows.
Roughly, this includes calculating the window start position in the
UNIX epoch context, handling the end period with an unknown duration
and taking the `adResumePosition` of an ad group into account that
affects the ad group start positions (`adGroup.timeUs`).
- Append a placeholder postroll ad group to the ad playback state of
each period in a live stream to allow immediate transition to an
ad that's inserted by an ad event from the SDK.
PiperOrigin-RevId: 516167958
The value returned by `player.getContentPosition()` is calculated
in the timeline based on the position of the first period in the
window. In a single period live stream this position is advanced
when the live window advances on timeline refresh.
This calculation has produced slightly varying values below 1000
us which are likely caused by us/ms truncations for public API
values that we use in the IMASSAIMediaSource.
However, `AdGroup.timeUs` is the (recorded) content position at the
moment when the first ad of the an ad group has been inserted. While
playing an ad, we can always use this value instead of
`getContentPosition()` to not require recalculation.

This change makes sure that the `AdPlaybackState` of any period can
contain an empty postroll placeholder.
The placeholder postroll should be represented in the `MediaPeriodId`
of a content period as `nextAdGroupIndex`, but should be ignored when
building the list of `MediaPeriodInfo` in the `MediaPeriodQueue`. This
is required to allow to add an ad group to ad playback state of the
content period that is currently being played, instantly insert an ad
period into the media period queue and immediately transition playback
to the new period.
This change makes sure and tests that
- a live server side inserted postroll placeholder can be inserted to
a `AdPlaybackState` in well-defined and tested way (helper method)
- a postroll placeholder is NOT ignored when
`AdPlaybackState.getAdGroupIndexAfterPositionUs` is called (this
is required when evaluating the `nextAdGroupIndex`).
- a postroll placeholder is ignored when
`AdPlaybackState.getAdGroupIndexForPositionUs` is called (this is
required to not attempt to play the ad and is analogous to ignore the
post roll placeholder in a single period timeline).
- `MediaPeriod.getFollowingMediaPeriodInfo()` does not include a
`MediaPeriodInfo` for the placeholder postroll when building the
queue.

Split test/ TransformerEndToEndTest into SingleMediaItemEndToEndTest and
SingleSequenceEndToEndTest to reduce the file size and split the tests
by category.

By making this method accept context, we can use DefaultDataSource.Factory in the DatasourceBitmapLoader to support a wider range on URI schemes in Bitmap Overlays. (and implement a local file picker for images for custom bitmap overlays in the demo transformer app)

Callbacks onTrackCount and onTrackAdded can be called simultaneously
from different threads.
Before this fix, it was possible for the MuxerWrapper and
FallbackListener track count to never be set, or to be set
with incorrect values.

We currently rely on the raw playback head position to check if any
data is pending in the AudioTrack (e.g. to know if the renderer is
still ready). We can use the value returned from getCurrentPositionUs
instead to align the "isReady" logic with the playback position logic.
This has the side effect that getPlaybackHeadPosition position is called
less often when the position is obtained via getTimestamp.

Custom commands from controller to session are blocked if they are
not listed in the available session command list. This isn't well
documented in the Javadoc currently.

Segment timelines are technically allowed to be empty, but not all places
add the necessary checks.
