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.

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 is a refactoring to separate and simplify the logic
of VOD and live streams when handling IMA ad events. An
additional listener will be required for DASH live stream
in a follow-up CL.

ImaUtil calls VideoProgressUpdate.equals() which is annotated as hidden,
which causes lint errors with gradle.

For TV devices the skip button needs to have the focus to be accessible with
the remote control. This property makes this configurable while being set to
true by default.

Initialising the fields as Integer and then getting a String on compute time is slow. Instead we directly initialise these fields as String. Improves the time taken in bundling PlayerInfo further to less than 200ms from ~300ms.
Also modified a test to improve productive coverage.

Some Player methods operate relative to existing indices in the
playlist (add,remove,move,seek). As these operations may be issued
from a place with a stale playlist (e.g. a controller that sends
a command while the playlist is changing), we have to handle out-
of-bounds indices gracefully. In most cases this is already
documented and implemented correctly. However, some cases are not
documented and the existing player implementations don't handle
these cases consistently (or in some cases not even correctly).
PiperOrigin-RevId: 495856295
BasePlayer simplifies implementations by handling all the various
seek methods and forwarding to a single method that can then be
implemented by subclasses. However, this loses the information about
the concrete entry point used for seeking, which is relevant when
the subclass wants to verify or filter by Player.Command. This
can be improved by adding the command as a new parameter. Since
we have to change the method anyway, we can also incorporate the
boolean flag about whether the current item is repeated to avoid
the separate method.
PiperOrigin-RevId: 494948094
These flags ensure that any errors cause the script to exit (instead of
just carrying on) (`-e`) and that any unrecognised substitution variables
cause an error instead of silently resolving to an empty string (`-u`).
Issues like Issue: google/ExoPlayer#10791 should be more quickly resolved with
`set -e` because the script will clearly fail with an error like
`make: command not found` which would give the user a clear pointer
towards the cause of the problem.

Rework the interface for ID3v2 text frames by:
- Switching from a mutable array to ImmutableList
- Never leaving the array empty, instead filling it with "" if there
are no values
This makes the surface safer and more in line with the rest of the
module.
These aren't caught by presubmit because the classes are annotated
`@VisibleForTesting` and are therefore stripped out by Metalava. However
Metalava doesn't run when we're generating javadoc for real.
#minor-release
PiperOrigin-RevId: 487476260
This uses `@hide` on `protected final` methods to hide them from Dackka
javadoc generation, since these methods are inaccessible to developers
anyway. These symbols will still (currently) be included in artefacts
distributed on Maven (because we don't run Metalava as part of
generating these artefacts).
In some cases I had to change the visibility/finality of methods to make
them `protected final` before adding the `@hide` annotation (but
the impact should be very low, since most of these methods were either
already unusable by app developers, or they shouldn't have been used).
#minor-release
PiperOrigin-RevId: 487472907
This makes two types of fix:
1. Align parameter names on overridden methods where the superclass
has `@param` javadoc.
2. Use `@hide` on `protected final` methods that refer to package-private
types. This will hide these symbols from Dackka javadoc generation
but not (currently) from the artefacts distributed on Maven. These
methods are currently unusable outside their package anyway (e.g. by
external developers) because of the dependency on a package-private
type.
This also changes some HLS, SmoothStreaming, and IMA code where I've renamed
parameters of overridden methods to be consistent across the type
hierarchy.

This ensure that ffmpeg error code are properly translated to values that the ExoPlayer decoder understand.
The main gain is that it allows the decoder to properly ignore more cases of invalid data and recover.
The second gain is that the other errors are now proper ExoPlayer errors and no more obscure buffer ones.

This change makes adding ad events in live streams more robust by allowing ad
groups to grow in number of ads if more ad events are received than initially
announced by the SDK.
With the IMA prefetch feature, an AdPod can grow in size in certain conditions
like from initially 2 ads to 4 ads being part of the ad group. With this change,
if an additional ad event arrives while the ad group is still being played,
the ad group is expanded. If the event arrives late and the ad group is already
completed, a new group is created for the remaining ads.
This also covers the case where we join the live stream while an ad is being
played and we missed at least one LOADED event from the SDK. Ads of the group
before the first LOADED event are ignored in such a case.
