Calling it directly might skip other callbacks. For example:
ActionSchedule.Builder().waitForTimelineChanged(...).build().
is currently immediately calling through to
callback.onActionScheduleFinished when the timeline changes.
Depending on the position of the action schedule listener in the
listener set, it may skip other listeners also
listening to timeline changes.

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
be updated. This means that a switch to or from speed or pitch = 1 would not be
handled correctly if made while paused and followed by a seek.
Move resetting active audio processors from configure (where if the active audio
processors were reset we'd always initialize a new AudioTrack) to initialize().

- This change snaps the seek position for constant bitrate MP3s
to the nearest frame boundary, avoiding the need to skip one
byte at a time to re-synchronize (this may still happen if the
MP3 does not really have fixed size frames).
- Tweaked both ConstantBitrateSeeker and WavHeader to ensure the
returned positions are valid.

Some streams don't have the new video resolution in the primary format.
Use the subsequent call to videoListener.onVideoInputFormatChanged to

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.

Currently FragmentedMp4Extractor only parses and outputs emsg messages if the
flag FLAG_ENABLE_EMSG_TRACK is set (when there's a metadata renderer that
handles emsg messages). Since there are emsg messages that only targets the
player, which we want to handle independently from MetadateRenderer, this CL
adds the ability for FragmentedMp4Extractor to output emsg messages to an
additional TrackOutput if provided, independently from FLAG_ENABLED_EMSG_TRACK.

- Avoid re-downloading data prior to the first mdat box when
seeking back to the start of an unseekable FMP4.
- Avoid re-downloading data prior to the first frame for
constant bitrate MP3.
- Update SeekMap.getPosition documentation to allow a non-zero
position for the unseekable case. Note that XingSeeker was
already returning a non-zero position if unseekable.

We can acknoledge seeks before preparation finished immediately now,
because ExoPlayerImpl won't leave the masking state until the first prepare
operation is processed.
As a side effect, it also cleans up the responsibility of the callbacks.
Prepares are always acknowledged with a SOURCE_INFO_REFRESHED, while seeks
are always acknowledged with a SEEK_ACK.

The ExoPlayerImpl implementation forwards the stop request with this optional
parameter. To ensure correct masking (e.g. when timeline updates arrive after
calling reset in ExoPlayerImpl but before resetInternal in
ExoPlayerImplInternal), we use the existing prepareAck counter and extend it
also count stop operations. For this to work, we also return the updated
empty timeline after finishing the reset.
The CastPlayer doesn't support the two reset options so far.

For this CL, it is assumed that null and "und" languages are different
entities. Once we fully tackle language tag normalization, we can decide
whether to normalize the "undefined" language.

A message to stop the playback and to quit the playback thread was posted in release().
The stop message removed all other already queued messages which might include
the second message to quit the thread. That led to infinite waiting in the
release method because the playback thread never got the quit signal.

Fixed by explicitly waiting for the timeline update. This shouldn't be
necessary and will be removed as soon as the correct order of events
can be guaranteed (timeline change -> state change -> onSeekProcessed).
The waiting for the timeline update is implemented by introducing the
feature that the test runner also waits until the action schedule has
finished before stopping the test.

In a test run where no exceptions were thrown on the main thread and the test
did not time out, exceptions from onPlayerError were not correctly propagated to
the test thread (handleException would be called with null).
Fix ExoPlayerTestRunner.onPlayerError to propagate the actual exception from the
player.

We've found that in our production environment, the AAC stream's timestamp exceeds the 33bit limit from time to time, when it happens, `peekId3PrivTimestamp` returns a value that is greater than `TimestampAdjuster.MAX_PTS_PLUS_ONE`, which causes a overflow in `TimestampAdjuster.adjustTsTimestamp` (overflow inside `ptsToUs`) after playing for a while . When the overflow happens, the start time of the stream becomes negative and the playback simply stucks at buffering forever.
I fully understand that the 33bit is a spec requirement, thus I asked our stream provider to correct this mistake. But in the mean time, I'd also like ExoPlayer to handle this situation more error tolerance, as in other platforms (iOS, browsers) we see more tolerance behavior.
