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.

Some of the CSS font sizes are derived from the current view height, if
this calculation is done before the view has been measured then a zero
view height results in a zero px font size and no visible text.

This can happen when the view type is changed (and so the
WebViewSubtitleOutput has been recently added to the SubtitleView
ViewGroup).

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.

This is the last piece to bring feature parity between
WebViewSubtitleOutput and CanvasSubtitleOutput.

It displays images too, and in fact it's used exclusively to display
images in SubtitleWebView. It also doesn't use a TextView - so all round
a slightly confusing name.

Also rename SubtitleWebView to WebViewSubtitleOutput to match the same
pattern.

This is useful for merging the FFmpeg video support pull request,
since it allows a Decoder base class implementation to catch
DecoderException rather than forcing it to catch Exception (i.e.,
everything). Note that unfortunately, Java doesn't allow catching
of a generic type (i.e., you cannot "catch (E e)") due to type
erasure.

The only reason to require a context for creating an instance of
DefaultMediaSourceFactory is creating a user agent. DownloadHelper
has a bunch of static methods that need to instantiate a
DefaultMediaSourceFactory without a Context. By adding a setter for
the user agent we can remove that restriction and use a default user
agent.

We aim for all SinglePeriodTimelines to set window.mediaItem and hence want to eliminate all constructors not passing a media item. The constructor removed in this CL is the easiest one to remove and fix in google3. It is still a breaking change for external ExoPlayer user who provide a custom media source with this timeline.

Log content progress events, as these are helpful to debug triggering of events
based on the content progress.

Don't log AD_PROGRESS events as they occur several times per second while ads
are playing, and the verbosity makes logs difficult to read.

It's very unlikely any onQueueInputBuffer implementations are looking
at the subsample encryption data, but from a correctness perspective
we should be passing a buffer object that's self-consistent.

FFmpeg requires input buffers to be sized larger than the size
of the data they contain. This is to allow optimized decoder
implementations that read data in fixed size chunks, without
the risk of such decoders reading beyond the end of the buffer.

It makes it harder to work with a different branch. Also make
the FFmpeg instructions consistent with those of the other
extensions (e.g., by removing the "jni" part of the path from
the FFMPEG_EXT_PATH variable.

We currently use the playback position in the current window, not the
position in the window the event belongs to. This creates confusing
outputs, e.g, window=1, mediaPos=100, even if the position refers to
window 0.

The tts:textAlign property only applies to <p> elements, which
correspond 1:1 with ExoPlayer Cue objects, so we can use
Cue.textAlignment to store this info instead of encoding it in
the span-styled text.

This will mean that TTML subtitles used with
SubtitleView#setApplyEmbeddedStyles(false) will start respecting
the tts:textAlign properties from the source data (currently this
information is stripped when we remove all span styling). I think this
is working-as-intended, we respect alignment of other subtitle types
(e.g. WebVTT) when applyEmbeddedStyles=false. We also respect all other
'positioning' related properties in this case e.g. Cue.position and
Cue.line.
