Whilst the previous behavior was WAI and had the advantage of
updating the position to be more exact when known, there were
a couple of disadvantages:
1. If seeking to the very end of a period in a playlist when
paused, the position adjustment could trigger a position
discontinuity to the next period.
2. We de-duplicate seeks to the current playback position.
The position adjustment can prevent this from being
effective. This is particularly important with the new
SeekParameters support. When seeking to nearest sync point
it's often possible to de-duplicate seeks, but we cannot
do so if the playback position adjusts away from the sync
point's time.

The set of active audio processors was only updated on reconfiguration and when
draining playback parameters completed. Draining playback parameters are cleared
in reset(), so if parameters were set while paused then the sink was quickly
reset, without draining completing, the set of active audio processors wouldn't

handled correctly if made while paused and followed by a seek.

captions fetcher architecture.
1. ManifestlessCaptionsMetadata
Other captions fetchers must first fetch a manifest (HLS or manifest) to
discover captions tracks. This process does not exist for manifestless. All
we need to do is scan the FormatStream's for the right itag, so this is an
all-static class.
2. ManifestlessSubtitleWindowProvider
Once a captions track is selected, a subtitles provider is instantiated. This
is the main interface used by the player to retrieve captions according to
playback position. This class stores fetched captions in a tree index by time
for efficient lookups. Background captions fetches are used to populate
the tree.
3. ManifestlessCaptionsFetch
Captions are fetched one segment at a time. One instance of this object
is required per fetch. It performs a blocking fetch on call(), and is
intended to be submitted to a background-thread executor.
4. ManifestlessCaptionsFetch.CaptionSegment
This is the result of the caption fetch. These values are used to populate
the captions tree.
Manifestlessness
The initial request is always a headm request. There is a separate tree
of every segment indexed by start time. This tree is used to improve
manifestless sequence number calculation. Once we have data for the current
timestamp, we walk forward through the tree to find the next unfetched
sequence number, and fetch that.

Now, media chunks may be discarded later on or in batches, leaving the

can be reported when the media chunk is first read from, while the discarding

First fix, prevents forced rewriting when cipher is set but encrypt is
false.
Second, removes the store() call in SimpleCache.initialize() so
initialization doesn't fail because of CachedContentIndex write issues.

The mediaChunks.size() > 1 check was supposed to ensure this, and
did roughly the right thing when there was only a single stream
(although it was unnecessarily restrictive in preventing chunk
cancelation for the first chunk, where bytesLoaded != 0 and none
of the samples had been consumed).
Now we have multiple streams the check doesn't do the right thing,
and adding a back-buffer feature will make even more incorrect.
This change switches to checking the condition we actually want
to check directly :).

1. Move Timeline/Manifest into PlaybackInfo
2. Don't update externally visible Timeline/Manifest during preparation
3. Ignore MSG_POSITION_DISCONTINUITY during preparation
4. Correctly set masking variables at start of preparation, and use them
Once this change goes in, PlaybackInfo will contain timeline, manifest
and position, which should always be self-consistent with one another.
The next step would then be to move a bunch of logic in ExoPlayerImpl
that derives state from timeline and position into PlaybackInfo, and
split that into its own top level class that can be easily tested to make
sure it never IndexOutOfBounds.
I think we could also replace the masking variables and instead just assign
a new PlaybackInfo to the playbackInfo variable whenever we're doing
something that requires masking. This should be possible because we no
longer update playbackInfo whenever we have pending acks. It would
require allowing PlaybackInfo to mask the window position internally when
the timeline is empty, but I think this is ok, and again is something we
could test pretty easily.

We don't expect this case to occur, since track selection is
normally expected to check canAcquireSession before selecting
a track. Nevertheless, if an attempt is made to acquire a
session when the media doesn't support the manager's UUID, we
should fail in a more graceful way.

- When transitioning to a new period, the value of bufferedDurationUs
passed to TrackSelection.updateSelectedTrack was incorrectly set to
0. It should have been set to correctly reflect buffered media in
previous periods still being played out.
- This change fixes the issue described above, and also propagates the
playback position through to this method. The position of the next
load within the period can be calculated by adding the position and
bufferedDurationUs.

newPlayingPeriodHolder could be set then updated if seeking to a repeated period

This change fixes various issues:
- MobileHarness sometimes allocated devices with SDK < 16. As we have no tests running
on these SDKs, a new dimension filter for the mobile_test target ensures that only
devices with SDK >= 16 are selected. A similar filter for SDK version is also added
to the ABR playback tests to ensure no old devices are selected.
- DRM specific tests are skipped for Api < 18, but were not able to run because the
DashTestRunner class tried to link to the MediaDrm constructor. Moved the
constructor to a seperate Builder class to allow execution on Api levels 16 and 17.
- DashWidevineOfflineTest also tried to access code for Api >= 18 without checking
the current level.
- Action implementations which are waiting for events did not ensure that they have a
nextAction to wait for. This caused NullPointerExceptions when this next action was
scheduled.
- DefaultDrmSession always restored the offline keys when a new license was requested,
even if the keys were already restored. These repeated slow calls to restoreKeys
resulted in high numbers of dropped buffers.

Update the audio track selection logic in DefaultTrackSelector:
- When forcing lowest bitrate, use bitrate as tie-breaker when track scores are
the same, prefer the lower bitrate.
- Otherwise, use one of the following values as tie-breaker in order:
- ChannelCount
- SampleRate
- BitRate
If the format being checked is within renderer's capabilities, select it if it
has higher tie-break value, else, select it if it has lower tie-break value.
If all tie-break values are the same, prefer the already selected track.

Controls are still hidden while playing ads, but if the app pauses the player,
controls will be shown. During ads, the player is not seekable.
When the player enters the background then returns to the foreground, the
content period may not be prepared, so also cache the content window duration.
This means that if the app reenters the foreground while an ad is paused the
time bar can be populated.

Updates DefaultDrmSessionManager to use the prefered Widevine version (v1
on >= 23 and v0 for < 23).
For other DRM schemes, uses the first scheme found.
* Always assume a renderer is ready if it's read to the end of
its current stream and there's a subsequent period already
prepared. This prevents getting stuck when a non-clock renderer
has a short stream.
* Switch to the standalone clock if the renderer providing the
media clock has read to the end of its current stream, is no
longer ready, and there's a subsequent period already prepared.
This prevents getting stuck when a clock renderer has a short
stream.
* Remove unnecessary clock synchronization logic (since it would
need to be made more complicated as a result of this change).
* Don't update the playing period holder when playWhenReady is
false. This avoids the position jumping to the start of the
next period when seeking to the very end of the current period
whilst paused (we still end up showing the first frame of video
from the next period, but fixing that will have to wait).

The refactoring is mostly mechanical and shouldn't result in any functionality
