- Android 12 will not allow our download service to be
restarted from the background when conditions that
allow downloads to continue are met. As an interim
(and possibly permanent) solution, we'll keep the
service in the foreground if there are unfinished
downloads that would continue if conditions were met.
- Keeping the service in the foreground requires a
foreground notification. Hence we need to be able to
generate a meaningful notification for this state.

Adding a CHANGE_FRAME_RATE_STRATEGY_ALWAYS strategy is
omitted from this commit, since adding it is more complicated
than just plumbing it through and leaving everything else
unchanged. Specifically, VideoFrameReleaseTimeHelper would
need updating to behave differently when such a strategy is
enabled. It currently calls setFrameRate in cases such as
pausing, seeking and re-buffering, on the assumption that
changes to the underlying display refresh rate will only be
made if they can be done seamlessly. For a mode in which
this will not be the case, it makes more sense to stick to
the content frame-rate when these events occur. It may also
make sense to only use explicit content frame-rate values,
and not those inferred from individual frame timestamps.
Finally, for adaptive content containing a mix of frame-rates,
it makes sense to use the maximal frame-rate across all
variants, and to avoid calling setFrameRate on switches from
one variant to another.
Applications that know the frame-rate of their content can
set ExoPlayer's strategy to CHANGE_FRAME_RATE_STRATEGY_OFF and
then use setFrameRate directly on the output surface. Note that
this is likely to be a better option for apps than anything we
could implement in ExoPlayer, because the application layer
most likely knows the frame-rate of the content earlier than
ExoPlayer does (e.g., to perform the disruptive mode switch
at the same time as an activity transition).
Adding CHANGE_FRAME_RATE_STRATEGY_ALWAYS will be deferred
until there's clear demand for it. In the meantime, we'll
recommend the alternative approach above.

The dokka javadoc generation tool complains when parameter names don't match between a method and its override. This change updates occurrences where there is currently a mismatch.
Notable renamings that might be controversial:
- `onPlaybackStateChanged(int state)` to `onPlaybackStateChanged(int playbackState)` affected a lot of lines but seems more consistent with other '-Changed' methods.
- `handleMessage(int messageType, Object payload)` to `handleMessage(int messageType, Object message)`
- `ExtractorInput` and `DataSource` inherit `DataReader` which had `read(byte[] target, ...`, while data sources normally called the first parameter `buffer`. I have standardized these all to use `buffer` even though it looks out of place in the `ExtractorInput` interface (which has more `read` methods with `target`).

The reason this was not an IO error code is that before other
IOExceptions were classified, this catch would grab non-IO error
codes, like ParserException. Now that we are getting closer to
the final state, we can assume IOExceptions are ok to classify
as IO error codes (unlike, for example, ParserExceptions or
DrmSessionExceptions).
PiperOrigin-RevId: 386496752
In some DataSources, it is not easy to assign an error code at the throw site.
For example, CronetDataSource.readInternal() throws SocketTimeoutException
on L1033, and is caught at L754 as IOException and is thrown.
We need the logic to assign error code for the actual type of the error cause.
While we can certainly do in individual DataSources, IMO there's value in
making this logic generic at a higher level (like what is in this CL).
The catch and translation logic is borrowed from EPII:L646.

Before this fix, if DefaultDrmSessionManager.release() was called while
there was at least one 'external' session reference still active (i.e.
session.referenceCount > 1) then the manager will release it's reference
immediately but when the session's reference count subsequently drops to
1 (due to external references being released) the manager will schedule
a task to release its internal reference *again*.
This change fixes the problem by only scheduling the timed release if
the manager is unreleased. This ensures that the internal references
are only released once.

A renderer is disabled (without being reset) in two situations:
* When transitioning into a period that starts with a discontinuity
* When stopping the player with setForegroundMode(true)
Before this change the behaviour of `MediaCodecRenderer` when disabled
(but not reset) depended on whether the content being decoded had an
associated `DrmSession`:
* For content without an associated DRM session the MediaCodec instance
was kept alive.
* For content with an associated DRM session, the MediaCodec instance
was released. This was to prevent the DRM session from staying alive
and continuing to make license refresh network requests while the
player was stopped in 'foreground mode'.
This change removes the second bullet, and keeps MediaCodec instances
alive in both the secure and insecure case. This will result in the
DRM machinery making occasional license refresh network requests (at
a frequency defined by the license policy) while the player is stopped
and in 'foreground mode'. This network usage is considered to be a
'limited resource' as described by the `ExoPlayer#setForegroundMode`
javadoc.
This means that switches between secure content (or between secure and
clear content when `MediaItem.drmConfiguration.sessionForClearTypes`
indicates a secure decoder should be used for clear content) should
keep the same video decoder, thus avoiding the 'black flash' that occurs
on some devices when switching the surface away from a secure decoder.

This change introduces a third 'state' for `DefaultDrmSessionManager`:
It's been fully released (prepareCount == 0) but at least one of its
sessions is still active.
In this state new acquisitions are rejected (`(pre)acquireSession()`
calls will fail) but the machinery to support the existing sessions
(ExoMediaDrm and MediaDrmHandler) is kept until they're all released.
This change will allow us to remove the TODO in MediaCodecRenderer
that resolves Issue: #8842.
PiperOrigin-RevId: 376193952

This allows to decouple the data structure from the access. In

Currently acquireSession() fails with an NPE from
checkNotNull(exoMediaDrm). A follow-up change will result in exoMediaDrm
sometimes being non-null while prepareCount==0 (and in this case we
still want acquireSession() to fail).
preacquireSession() doesn't currently fail in a way the caller can
observe - the same NPE is thrown, but asynchronously and it doesn't
propagate out of the background thread. Throwing directly seems
preferable since it's a clear bug to be trying to preacquire sessions
from an unprepared/released manager.

This media source wraps another source and publishes a Timeline with
ads. The created MediaPeriods for ad and content are mapped back to
the original stream to allow seamless playback.
PiperOrigin-RevId: 374836091
There is a newly added condition to help advancing between SSAI ads
and content in case the ad group position or ad duration changed. The
condition currently doesn't check directly whether it's a SSAI
transition but relies on indrect signals. Making this more direct
helps to understand the purpose and avoid unintentional bugs where
this condition would apply in other cases too.
In addition, we need to exclude TextRenderer from the check because
its read position doesn't correspond to the actual decode position
since the decoding happens in the renderer itself (b/181312195).
PiperOrigin-RevId: 374835985

When working with SSAI ads, we need to easily convert positions between
the underlying stream and the media model that exposes ad groups. To
simplify this, we can add util methods (that are testable on their own).
In addition, we need an easy way to build AdPlaybackStates for SSAI
inserted ads. The metadata is obtained out-of-band and usually has the
ad group start and end times in the underlying stream only. Hence, we
also add a util method to add a new ad group based on this information.
PiperOrigin-RevId: 374369360
There are two main changes that need to be made:
1. Whenever we determine the next ad to play, we need to select a
server-side inserted ad even if it has been played already (because
it's part of the stream).
2. When the Timeline is updated in the player, we need to avoid changes
that would unnecessarily reset the renderers. Whenever a Timeline
change replaces content with a server-side inserted ad at the same
position we can just keep the existing MediaPeriod and also if the
duration of the current MediaPeriod is reduced but it is followed by
a MediaPeriod in the same SSAI stream, we can don't need to reset
the renderers as we keep playing the same stream.
PiperOrigin-RevId: 373745031
Content after ad groups currently always resumes at the ad break position (unless
overridden by a seek or similar). In some cases, media inserting ads wants to
specify an offset after the ad group at which playback should resume. A common
example is a live stream that inserts an ad and then wants to continue streaming
at the current live edge.
Support this use case by allowing ad groups to specify a content resume offset
and making sure that the content start position after the ad group uses this offset.
PiperOrigin-RevId: 373393807
The player already supports changing durations of periods and ads.
The only thing not yet supported is a change in ad break positions
which changes the duration of clipped content ending in an ad break.
Adding support for this requires updating the end position in
MediaPeriodInfo and changing the clip end position of the respective
ClippingMediaPeriod.
Issue: #5067
PiperOrigin-RevId: 373139724
The method to handle Timeline updates currently uses
isAd() || isPlaceholder()
to trigger two things:
1. Using the existing requested content position as the content
position.
2. Re-resolving the content position from window to period in case
it changed since the last update.
The condition is correct for case (1) because ads must use the content
position (and not the position in the ad) and a placeholder period must
keep using the requested content position as well until the media
information is no longer a placeholder.
However, case (2) only needs to be done if the content position is
C.TIME_UNSET (to start at the default position) OR if the period is
still a placeholder and we want to re-resolve the position.
The case where re-resolution shouldn't be done is for ads with a non-
placeholder period and a concrete content position. This likely only
affects ads in live stream where the content position is currently
moving with the live stream instead of staying where it is.

As a result `VideoListener` and `AudioListener`
can be deprecated in favor `Listener`.
On the other hand `TextOutput` and `MedataOutput`

This means that those class can't be deprecated.
There usage in the public interface are indirectly

Move VideoSize in the common module and have the Player return it.
`Listener` and `AnalyticsListener` `onVideoSizeChanged` are updated
with the old method deprecated.
`VideoRendererEventListener.onVideoSizeChanged` was also migrated to
`VideoSize` but the old method is removed, not deprecated.
This is because:
- apps calling/listening to this method is a rare and niche use-case.
- it would introduce hard to diagnostic issues where if only the caller
or the callee is updated to use the new method, the event will be lost.
This doesn't occur with the other 2 listeners as the caller is always
in ExoPlayer library and was updated to call both the old and new methods.
VideoSize is used everywhere except in `Format` as this would lead to
too much refactoring and backward compatibility breakage for little gain.

1. Clarify intention of getAdGroupIndexForPositionUs and

3. Update MediaPeriodQueueTest for updateQueuedPeriods to only

Release is a life cycle operation that should only be called when
the player is no longer needed. It's linked to the player lifecycle
and thus very different from prepare/stop.
As a result, it should not be in the same command.
Additionally it's not clear if remote players will ever need to call release,
as the player creator is best candidate to release it.
As a result the release operation doesn't have a use case for a command.

ExoPlayerImpl.setMediaSourcesInternal() with startWindowIndex=0 and
resetToDefaultPosition=false.
- ExoPlayerImpl.prepare(mediaSource) ended up calling

startWindowIndex=C.INDEX_UNSET and resetToDefaultPosition=true.

Even when fixed to the US locale (and thus avoiding surprising behaviour
in e.g. Turkish locale with "i" and "I") there are unexpected behaviours
when upper and lower casing non-ASCII characters.
For example it's sometimes not symmetric, e.g.:
"ẞ".toLowerCase() -> "ß"
"ß".toUpperCase() -> "SS"
In all the ExoPlayer usages we are either dealing with known-ASCII
strings (e.g. MIME types) or comparing against ASCII constant strings
anyway, so it seems easier to just use Guava's ASCII-only class in these
cases.
Util.toUpperInvariant() is null-tolerant, while Ascii.toLowercase() is
not. Most usages in this change are clearly non-null. The BandwidthMeter
usages aren't annotated @Nullable, but the current code *would* work if
countryCode was null in both cases. These methods will now throw NPE if
they're passed null.

I'll make an equivalent change for Util.toUpperInvariant() next.
PiperOrigin-RevId: 368419813
Previously, we had separate MSG_SET_SURFACE and
MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER messages for
setting different types of supported output. Use of these
constants to switch between outputs during use of a player
was confusing because not all video renderers support both
message types.
To switch from VideoDecoderOutputBufferRenderer to a Surface,
it was sufficient just to send MSG_SET_SURFACE, since all
video renderers support this and clear any other output that
might be set. Conversely, to switch in the opposite direction,
just sending a MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER was
not sufficient, because not all video renderers handle this
message to clear any previous output. Hence it was necessary to
explicitly clear a previously set surface using a separate
MSG_SET_SURFACE message. Passing two messages to switch the
output may prevent renderers from implementing the output switch
efficiently.
This change passes all outputs using a single message type, and
requires that all renderers treat unsupported outputs as though
null were passed (i.e., they clear any existing output). There
are some other miscellaneous improvements:
1. Non-surface outputs are now passed to onRenderedFirstFrame.
This fixes a bug in SimpleExoPlayer's onRenderedFirstFrame,
where previously it could not correctly equality check the
output corresponding to the event to its current output in
the VideoDecoderOutputBufferRenderer case.
2. Fix SimpleExoPlayer to report surface size changes for the
VideoDecoderOutputBufferRenderer case. Even though the
surface is rendered to indirectly in this case, we can still
query (and listen to changes to) the surface's size.

If this condition isn't true, the player may enter a cycle of discarding
and reloading the same format. As minDurationToRetainAfterDiscard is a

case and log a warning instead of asserting it outright to prevent
unnecessary app breakages.

Prior to this change, there were some unrealistic quirks in
our Robolectric tests. For example, onRenderedFirstFrame would

This was added in 9609af3c23 as part of a LSC.
The RequiresNonNull annotation doesn't work anymore (it doesn't
recognize the outer class member and instead tries to find

the warning of the non-fulfilled precondition, we can just

The main change here is that VideoDecoderGLSurfaceView now implements
VideoDecoderOutputBufferRenderer directly. This avoids SimpleExoPlayer
having to cast to VideoDecoderGLSurfaceView, which will be necessary
if VideoDecoderGLSurfaceView is moved to the UI module. Instead, the
player can cast directly to VideoDecoderOutputBufferRenderer, which
could be moved to the Common module.
The renderer is also moved to be an inner class, since it's not used
anywhere else and since doing this makes it a little easier to move
things around.

We added a source that allows mixed placeholder and non-placeholder
periods, but have no way to denote that in the Timeline because the
placeholder flag only exists on Window level. This causes a bug if
the first item in a concatenation has a window-period offset and the
player can't detect whether it's still a placeholder or not.
Adding this flag to Period allows the player to detect this reliably.
In addition we need to make sure that re-resolving pending positions
only happens for the first placeholder period where the window-offset
can actually change. As all subsequent periods have to start at position
0, so they don't need to be re-resolved (and shouldn't).

If the player is created on a background thread (which is allowed
as the only exception to the access-on-one-thread-only rule), it
may happen that a callback on the main thread tries to access the
player before the constructor even finished. This is dangerous and
can cause exceptions due to uninitialized variables.
To solve this, we can make sure that every player access is blocked
until the constructor finished. Blocking is safe because the
constructor itself is not doing any blocking work or acquiring locks.
The thread verification method is already called on every entry
point to the player, so we can reuse the same method for checking.
PiperOrigin-RevId: 365792949
The extended onPositionDiscontinuity callback can be used to improve some
listener classes:
- Listening to onTimelineChanged to detect discontinuities is no longer needed.
- Listening to onSeekStarted is no longer needed as the start position is part

- The exact old position is also useful for media time history logging.

MaskingMediaSource needs to resolve the prepare position set for a MaskingPeriod

PiperOrigin-RevId: 359092124
Assert that an exception is not thrown from DataSource.open
if the DataSpec's start position is valid but its end position
extends beyond the end of the data.
HTTP based DataSource implementations have no good way of
knowing when this is the case, so it makes sense to make this
the required behaviour, rather than requiring an exception to
be thrown or allowing both.
There are also use cases where the caller may want to use the
end position as an upper bound, without knowing for sure how
long the content is. An example of this use case is wanting to
pre-cache the first N bytes of a stream. This implies that any
exception should be thrown after reading to the end of the
data, rather than preemptively in open.

When we add DRM pre-acquire support to SampleQueue, we'll dispatch
twice the number of acquire and release events. This is slightly
confusing, since there's the same number of
DrmSessionManager#acquireSession() calls.
We can mitigate this by only dispatching each acquire and release
event to at most one EventDispatcher.
This also changes the events fired when playing a stream with both audio
and video encrypted with the same keys (even without pre-acquisition).
Before: The EventDispatcher would see 2 aquires, 1 key load and 2
release events.
After: The EventDispatcher will see 1 acquire, 1 key load and 1 release.

This is a no-op assuming the class is always used correctly.

`TrackSelection` had mutation methods which were to be called only
internally by ExoPlayer components but were exposed in the
public `Player` interface.
The mutation methods have been moved out of `TrackSelection`
to a new class `ExoTrackSelection`.
Current track related read-only method have also been moved out,
because they are actually something quite unclear.
Even for a single item playlist, it's the track being buffered rather
than the track being played, which is unclear.
But when you have a playlist it starts to get really confusing,
because if the next item is being buffered, then it's actually
the last track to be buffered in the currently playing item.
As a final aside, the implementations don't do proper thread synchronization
to ensure visibility of updated state by the calling thread.
Exposing those mutable methods in the public `Player` interface
was problematic because they leaking internal concepts of `ExoPlayer`.
This is also required to minimize the `Player` interface for long term
stability.
`ExoTrackSelection` is a subclass of `TrackSelection`.
This is not ideal as an `TrackSelection` implementation could
break the current immutability.
This was done in order for this refactor to be simpler.
A future patch will fully split the two classes.
All `MediaPeriod` and `Sources` had to be updated to use the new
`TrackSelection` dynamic aspect class name.
An alternative would have been to break ExoPlayer's public API, keeping
`TrackSelection` as the dynamic aspect name, and calling the public static
aspect class `TrackSelectionState` or similar.
Nevertheless, while it would have impacted less files, it would have
many more small apps and casual users of ExoPlayer.

`ImaAdsLoader` only loads ad media URLs once playback of the preceding ad (if
any) has started, and this behavior is likely to be similar for other ad loader
implementations due to limits on how long before an ad plays it is meant to be
loaded. This is problematic for very short ads followed by an ad because the ad
will load to the end but load control may not allow playback to start due to
the total buffered duration being low.
Fix this by allowing playback to start regardless of load control if we are
waiting for an ad media period to prepare.
An alternative fix would be to fake the ad progress in the `ImaAdsLoader` to
trigger loading the next ad, but this would only allow one ad to load ahead (so
the problem would remain for two short ads in a row followed by another ad).

One drawback of this approach is that a `TrackSelectionArray`
has to be allocated on the boundary of the `Player` interface.
This should not be a performance issue as this only happens
on trackSelection changes, when the user calls
`Player.getCurrentTrackSelections` and on
`updateLoadControlTrackSelection`.

This field changed name during the code review, but these names and
references weren't updated to match.
Also use an ImmutableSet since the field is a Set.

This ensures the message devilery is governed by the clock.
Also replace setting a Handler with a Looper to facilititate this
change.

Codecs are not used by this test because PCM uses codec bypass,
but performing the setup is still necessary to have the test
verify that this is indeed the case!

The output dumps are intentionally empty because the playback
is using bypass modes.
Still adding a AUDIO_RAW decoder to the ShadowMediaCodecConfig to
ensure that we would output samples if bypass mode were disabled.
