Audio processors are now flushed twice after reconfiguration.
The second flush call cleared the pending trim start bytes so
transitions between tracks were no longer gapless.
Fix this by removing logic to clear pending trim bytes on flush.
As a result we may trim data incorrectly if there is a flush
before any data has been handled for seeking to a non-zero
position, but this edge case will happen rarely and the effect
shouldn't be noticeable.

If we're in the ducked state and updateAudioFocus is called with a
new state for which focus is no longer required, we should restore
the player back to full volume.

This avoids cases where audio focus is never successfully acquired
because another app is holding on to transient audio focus indefinitely.

handlePrepare/Stop/SetPlayReady can be merged together as they all
handle changes to the desires state of the player.
Also, simplify parts of the control flow by not mixing code that
determines if audio focus needs to be handled with code that actually
acquires or abandons the focus.

When ClippingMediaPeriod first tried to read a buffer, if its end
position was before the end of the stream and it was buffered to its end
position, it would sometimes erroneously signal end-of-stream for
protected content because the sample queue might be waiting for DRM keys
at this point.
Work around the issue temporarily by signaling this specific case back
to ClippingMediaPeriod via the DecoderInputBuffer.
There will likely be a cleaner fix as a result of adding support for
dynamic clip end points in the future, at which point this can be
reverted.

- They are always listed with their canonical names
- Considering aliases means that blacklisting a decoder can end up
not actually blacklisting it, since it may still be accessible
via an alias. It also means that our decoder fallback logic can
end up falling back to a decoder that we've already tried!

This is less confusing than having audio processing functionality (e.g., playback
speed adjustment) just "not work" for some pieces of media.

If the start time of the edit falls within a sample, start from that
sample rather than the next one. This ensures playback can start from

It's not clear why we're currently outputting the format in both init()
and consume() - it seems likely that this was accidentally introduced
in <unknown commit>
when we started outputting the format in consume() but didn't remove it
from init().
CryptoInfo.iv length is always 16. When the actual initialization vector
is shorter, zero out the trailing bytes.

This condition is trying to detect when it might be necessary
to switch from a non-secure to a secure codec. This is not
possible if the DRM session is unchanged, unless a different
codec is required for some other reason (e.g., H264 -> H265),
which is anyway handled by canKeepCodec below.

Passing EXT-X-KEY DrmInitData through the FragmentedMp4Extractor
doesn't work for streams with key rotation, because an extractor
instance is used for multiple segments, but is only passed the
EXT-X-KEY DrmInitData corresponding to the first segment.
This change removes passing DrmInitData through the extractor,
and instead passes it via FormatAdjustingSampleQueue. This is
in-line with how manifest DrmInitData is handled during DASH
playbacks.

- Add additional Listener methods to DownloadManager, to inform of
changes to whether the downloads are paused or waiting for requirements.
- Only schedule the Scheduler if we really are waiting for requirements.
- Only restart the service if we're no longer waiting for requirements,
and if there are queued downloads that will now be restarted.
Previously the service would be restarted whenever the requirements
were met, regardless of whether there was any work to do.
- Restart service if it might be stopping, as well as if it's already
stopped. Also restart service if there's a download state change to a
state for which the service should be started, if.

Doing so prevent Codec which is a big object with
JNI to be garbage collected.
As the codec can not be hold in the listener, there
is no way to call release, as it must be called on
the same codec.
As a result the release method is also removed.
The downside is that at runtime some callbacks may be
dropped but it should be a short transitive state.
This also simplifies lifecycle of the listener as
the client does not have to know if release needs
to be called or not.
An alternative would have been to hold a weak ref,
but I deemed it too complicated for the
runtime gain.

This fixes an issue where a DownloadService implementation
that allows foreground but doesn't provide a scheduler would
not be restarted in the case that it was still in memory but
classed as idle by the platform.
It also speeds up service restart in the case that a
scheduler is provided.

This method has two use cases:
1. Seeking. Calls are immediately preceded by a call to rewind(), and
the returned value isn't important unless it's ADVANCED_FAILED (i.e.
the caller is only interested in success and failure).
2. Advancing. The return value is important unless it's ADVANCED_FAILED,
in which case the caller wants to treat it as 0.
This change creates separate methods for each use case. The new seekTo
methods automatically rewind and return a boolean. The updated advanceTo
method returns 0 directly in cases where ADVANCED_FAILED was returned.
Arguments that were always hard-coded to true by callers have also been
removed.
This change is a step toward one possible solution for #6155. How we'll
solve that issue is still up for discussion, but this change seems like
one we should make regardless!

- DownloadManagerHelper now passes all downloads to the
DownloadService when the service is attached (and once
the downloads are known). The service then starts the
foreground notification updater if necessary. This fixes
the ref'd issue.
- Don't call getScheduler() if the service is background
only. This was already documented to be the case on the
DownloadService constructor.
- If the service is started in the foreground on SDK level
26 and higher, satisfy the condition to move the service
to the foreground in onStartCommand rather than in stop().
It's much more obviously correct, and should produce the
same end result.

This optimization allows a ChunkSampleStream to output track
formats as soon as they're parsed during an InitializationChunk
load, rather than waiting until after the InitializationChunk
load is completed.
In DASH VOD, a single InitializationChunk typically loads the
moov and sidx atoms in that order. Hence for long form content
where the sidx is a non-trivial size, this may result in the
track formats being output a non-negligible period of time
sooner than was previously the case. This allows downstream
renderers to start codec initialization sooner, potentially
decreasing startup latency.
For a single test stream on a fast & stable network, this
pretty consistently reduced elapsed time until both audio and
video codecs have been initialized from ~0.5s to ~0.3 seconds
on a Galaxy S8. For 5 test runs without and with these patches,
the eventTime logged by EventLogger for the second decoder
init were:
Without (secs): 0.47 0.47 0.45 0.48 0.46
With (secs) : 0.32 0.33 0.34 0.31 0.40
PiperOrigin-RevId: 289845089
The current order of operations means that the Format is only passed
to the chunk's output after the DataSource has been opened. This
means that establishing the network connection and the downstream
renderers initializing their codecs are effectively serialized to
occur one after the other.
In the new order, the Format is passed to the chunk's output before
the DataSource has been opened. This allows the downstream renderers
to initialize their codecs in parallel with the network connection
being established, and hence latency at the start of playback is
reduced.

As discovered whilst investigating #6798, there are cases
where these methods are not correctly. They were added as
convenience methods that could be overridden by concrete
DownloadService implementations, but since they don't work
properly it's preferable to require application code to
listen to their DownloadManager directly instead.
Notes:
- The original proposal to fix#6798 stored the state change
events in memory until they could be delivered. This approach
is not ideal because the events still end up being delivered
later than they should be. We also want to fix the root cause
in a different way that does not require doing this.
- This change does not fix#6798. It's a preparatory step.

This change makes it clear the SampleQueue doesn't outlive
the wrapping PlayerTrackEmsgHandler, and releases it from
PlayerTrackEmsgHandler.release().
This change is a no-op because calling release() is the
same as reset() in this case (the behavior only differs if
a non-dummy DrmSessionManager is being used).

therefore configured with the wrong expected output data).
