All methods check if the player is currently handling the ad source
by calling isCurrentAdPlaying(). This method was missing a check
for empty timelines that throws an exception when trying to access
a non-existent period.
Also add this check to two methods that assume the current item
is the ads source, but didn't check it yet.

This helps to play ads where the file extension is not sufficient
to deduce the correct source in DefaultMediaSourceFactory.

Currently, ads are only defined by a single URL, which makes it
impossible to define additional fields needed to play ads correctly.
This can be fixed by using a full MediaItem in AdPlaybackState,
replacing the previous Uri field.

Both interfaces are not really needed as the methods can be called
on the respective classes directly. This also avoid error-prone
situations where classes define to/fromBundle methods with parameters
that should be used instead of the parameter-less version.
Also deprecate all existing CREATOR static instances and make the
corresponding fromBundle method public where needed.

The period index was calculated relative to the contentTimeline
of the DAI stream, but then used with the full timeline of the
player. This means it currently only works when the stream is the
only or first item in the playlist.
Issue: androidx/media#571
PiperOrigin-RevId: 560023412
This change addresses the case when the user joins the live stream
on an ad period but the metadata for the ad period is not emitted.
This results in inserting a partial ad group.
In this case the ad group duration is longer than the partial ad
group. If now the partial ad group ends at the period before the
last period of the window (unknown duration), the splitting algorithm
didn't recognize that the ad group already ended and made the last
period wrongly an ad period.
This change handles this edge case by counting the mapped ads in
the partial ad group to detect this situation and stops splitting.

This change improves `ImaUtil.maybeCorrectPreviouslyUnknownAdDuration` to
handles the case when the timeline moves forward more than a single period
while an ad group with unknown period duration is being played.
PiperOrigin-RevId: 522292612
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.
PiperOrigin-RevId: 520919236
This change makes sure that live ad periods that are played are
skip when attempted to be added to the queue. To make this work
the existing filter logic had to be take into account the content
resume offset that live periods use.
PiperOrigin-RevId: 518068138
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
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.

Ignorable ad periods are skipped to resolve the media period id with the
ad playback state of the resulting period. In case of a change in the period
position un-played ad periods are rolled forward to be played.

Right now, the option to build an IMA DAI URI programmatically is still
package-private. To simplify the process, we can remove the StreamRequest
wrapper and directly provide an URI builder.
The same class can provide some package-private helper methods to parse the
created URI.

This makes sure the number of ads in an ad group matches to the number of periods representing an ad group in a multi-period timeline. This makes it easier to accurately mark ads as played in multi-period windows which is needed to correctly prevent seeking over unplayed ads.

Where this introduced an inconsistency (e.g. assigning to something
called `windowIndex`), I generally renamed the transitive closure of
identifiers to maintain consistency (meaning this change is quite
large). The exception is code that interacts with Timeline and Window
directly, where sometimes I kept the 'window' nomenclature.
