ANSI/CTA-608-E R-2014 Annex B.5 says:
"The concept of a movable base row for a roll-up caption is new."
It means "new" compared to TC1 and TC2 (released in or before 1985).

Output timestamps are calculated by the codec based on the buffers,
which is offset in Codec2. This adjusts the input timestamps as they
are passed in so they will match the output timestamps produced by
the MediaCodec.

bear_vorbis_gap.ogg is a copy of bear_vorbis.ogg with 10 garbage bytes
(DE AD BE EF DE AD BE EF DE AD) inserted before the second capture
pattern and 3 garbage bytes inserted at the end (DE AD BE).

Previously if the AudioCapabilities reported that an encoding/channel count was
supported, DefaultAudioSink could try to play it via passthrough. However,
DefaultAudioSink does not support passthrough of every possible format (for
example, it's likely that AAC passthrough does not work given it's never been
tested and recent GitHub issues indicate that trying to use it leads to no
audio being played).
Add additional checks to make sure the encoding is in the list of encodings that
are known to work with passthrough in DefaultAudioSink.

Guava is heavily optimized for Android and the impact on binary size
is minimal (and outweighed by the organic growth of the ExoPlayer
library).
This change also replaces Util.toArray() with Guava's Ints.toArray()
in order to introduce a Guava usage into a range of modules.

EventTime contains information about when an event happened and where
it belongs to. Both places can be fully described using timeline, window
index, media period id and position.
Right now, only the information for where the event belongs to is fully
contained in EventTime, whereas the time when the event happened only has
the position, and none of the other information (timeline, window, period).
This change adds the missing information, so that the EventTime can easily
be used without having access to the Player. This also ensures Event
metadata is self-contained and can be stored and reused later.

ANSI/CTA-608-E R-2014 spec defines exactly 32 columns on the screen,
and limits all lines to this length.

Some player setup steps that are likely to be only done once
should be moved into the Builder so that player setup can use
a consistent style (builder vs setters).
This also prevents some threading warning issues when the player
is built on a background thread (e.g. for dependency injection
frameworks) and setters can't be used due to threading restrictions.

Users of addTextOutput should instead query the current cues if they
need them. This is more consistent with how other listeners are handled.

Now that MediaCodec is not use in passthrough, no
MediaCodec should be created in this mode.
Additionally, do not instantiate a MediaCodec in passthrough

We keep an index hint for the next pending player message. This hint
wasn't updated correctly when messages are removed due to a timeline
update.
This change makes sure to only use the hint locally in one method so
that it doesn't need to be updated anywhere else and also adds the "hint"
suffix to the variable name to make it clearer that it's just a hint and
there are no guarantees this index actually exists anymore.

Steps 4-10 of https://www.w3.org/TR/webvtt1/#cue-computed-line
This part is harder to fit into our code structure because it depends on
how many cues are simultaneously visible - so it has to go in
WebvttSubtitle not WebvttCueParser (which only deals with individual
cues in isolation).
This removes the `isNormal()` method that was trying to approximate
the correct behaviour.

Android scheduler has performance issues when a device has a
combiation of big/medium/little cores. Add a heuristic to set the
default number of threads used for deocding to the number of
"performance" (i.e. big) cores.
