0ceff589b3 HLS Bugfix: Avoid loading initialization segment when reusing extractor
This bug affects any playlist that uses initialization segments. In practice,
almost exclusively fragmented mp4 segmented playlists are affected.

The bottom line is that extractors are chosen for reuse after the
initialization segment connection is open. However, reused extractors
do not need re-parsing the init segment, so loading the initialization is
wasteful.

c6195dbbaf Handle recreation of TrackSelectionView instances.
TrackSelectionView requires an initialization with a call to init(...).
That's why we shouldn't let the view retain its view hierarchy automatically
as the views won't be backed by data if restored. Instead add a listener
which lets the containing activity/fragment save and restore the state if
needed.

b69041bea2 Prevent NullPointerException exceptions in SimpleCache initialization
This is a temporary fix to prevent NullPointerException exceptions.
Though writing to cache will still fail if the cache folder isn't a real
folder.

There are a few thing we can try:
* The listing might be failing because the cache folder is just created.
We can wait and try again.
* If the cache folder is a regular file, we can try deleting and creating
a folder with the same name.

31911ca54a Drain audio processors on reconfiguration
Previously we would get a new AudioTrack and flush all audio processors if any
AudioProcessor needed to be flushed on reconfiguration. This was problematic for
the case of TrimmingAudioProcessor because it could become active or inactive
due to transitioning to a period with gapless metadata or without it (we don't
keep it active all the time because it is wasteful to populate its end buffer
for content that is not gapless).

This change handles the case where we don't need an AudioTrack but
AudioProcessors do need to be flushed. In this case we drain all the audio
processors when next handling data then switch to the new configuration.

This avoids truncation when period transitions change whether
TrimmingAudioProcessor is active but don't require a new AudioTrack, and is also
a step towards draining the AudioTrack when transitioning between periods if we
do need a new AudioTrack.

To do this, it needs to be possible to drain any pending output data from an
AudioProcessor after it's configured to a new format, so this change makes sure
AudioProcessors allow calling playToEndOfStream and getOutput after
reconfiguration and before flush.

c66d26b601 Fix EventMessage timestamp issue
Stop encoding/decoding presentation time as part of the message.
What's actually in emsg boxes is a presentation time delta,
which is why it's only 32 bits, and hence why it doesn't handle
large absolute timestamps. We were using this field to hold
absolute timestamps only for the purpose of passing presentation
times from DashManifestParser.parseEvent back to the calling
method. After this change, we return Pair<Long, EventMessage>
instead.

Imported from GitHub PR https://github.com/google/ExoPlayer/pull/5438

Plus the following changes:
- Only support profile 5 (handling other profiles requires
  backward-compatibility changes in the renderer which are left for a later
  change.)
- Only add KEY_PROFILE to the codec configuration MediaFormat for Dolby Vision.
- In MediaCodecUtil support all DV profiles that Android has constants for. This
  includes ones that are "not supported for new applications". Since we don't
  extract these profiles, this is currently only for the benefit of custom
  extractors.
- Misc code style fixes and reordering for consistency.

391f2bb6c2 Remove indirection in DefaultDownloadIndex
DefaultDownloadIndex is currently just forwarding all calls to its
inner class. getDownloadTable() handles initialization, but this
doesn't really seem different to having an initialization method. It
doesn't guarantee initialization happens, since a bad method
implementation could try and access downloadTable directly, just as
a bad method implementation could forget to call the initialization
method. Hence this change removes the indirection.

 2. Using ExoPlayer's QoE extension (which is also an AnalyticsListener).

track group is selected).

39505452de Make VersionTable static
The way it is currently, it's very unclear that an operation on the
version table will correctly belong to a transaction in code such as
this, taken from DefaultDownloadIndex:

writableDatabase.beginTransaction();
try {
  writableDatabase.execSQL(...);
  versionTable.setVersion(...);
  writableDatabase.setTransactionSuccessful();
} finally {
  writableDatabase.endTransaction();
}

This change explicitly passes the database, to make it obvious that
the operation will really go into the same transaction:

writableDatabase.beginTransaction();
try {
  writableDatabase.execSQL(....);
  VersionTable.setVersion(writableDatabase, ...);
  writableDatabase.setTransactionSuccessful();
} finally {
  writableDatabase.endTransaction();
}

866835ea03 Fix float output capability check
Float output is only possible from API 21, but the high-res int
to float conversion path was checking for 32-bit PCM not float
output capability.

a1c13ca6f5 Hack to instantiate ExoDatabaseProvider without a context
This will allow CachedContentIndex to start using database
storage without us having to change the SimpleCache and
CachedContentIndex constructors to require a Context or a
DatabaseProvider.

582adb748a Decouple end position from MediaPeriodId again.
If are allowing changing durations of periods, we shouldn't use the end position
of clipped content as part of the id as it may change. This change moves the end
position back to MediaPeriodInfo and adds the next ad group index to the id
instead to ensure we still have unique ids for all content parts.

355b3d6334 Increase minSdkVersion to 16
The combination of pre-16 API levels accounting for ~0.5% of the device
population, and that the most important components in ExoPlayer (e.g.
the MediaCodec renderers) have always required API level 16, mean it's
very unlikely this will negatively impact on anyone.

f182c0c116 Centralize serialization in CachedContentIndex
We need to support serialization to/from an SQLite table. The
model of passing something around for each class to write into
doesn't work well for SQL, and it would be messy to have two
different structural designs for serialization. This change
centralizes the logic in CachedContentIndex, where a centralized
SQL based version can more easily sit alongside it.

49b9775d08 Add getReadingPositionUs to Renderer.
This method is a generalization of the existing hasReadStreamToEnd. It is
useful to determine whether a renderer already read beyond a new duration of
a period.

d7b3820175 Make updateQueuedPeriods more readable and fix bug.
1. The method kept track of the current period index to check if the next
period is still in the correct period. This is unneccessary since we no longer
use the period index but the actual uid in MediaPeriodId and mismatches are
already detected by canKeepMediaPeriodHolder.
2. We updated the MediaPeriodIndfo twice: once in getFollowingMediaPeriodInfo
and once in getUpdatedMediaPeriodInfo. That's confusing and difficult to
follow. The only difference is that getUpdatedMediaPeriodInfo keeps the
content position while getFollowingMediaPeriodInfo resets it. This is made more
explicit for readability.
3. The durations compatibility check for all following periods was broken as
it compared the same durations (partly due to the confusion caused by 2.)
