We currently don't display the last frame because the seek time is behind the
last frame's timestamps and it's thus marked as decodeOnly.
This case can be detected by checking whether all data sent to the codec is
marked as decodeOnly at the time we read the end of stream signal. If so, we
can re-enable the last frame. This should work for almost all cases because the
end-of-stream signal is read in the same feedInputBuffer loop as the last
frame and we therefore haven't released the last frame buffer yet.

This bug affects any playlist that uses initialization segments. In practice,

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.

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.

We currently default to not caching data if the content length
cannot be resolved once the DataSource has been open. The
reason for this is to avoid caching progressive live streams.
By doing this we were accidentally not caching in other places
where caching is possible, such as DASH/SS/HLS segments during
playback if the server doesn't include a Content-Length header.
Also HLS encryption key chunks, which were very unlikely to be
cached during playback because we explicitly set FLAG_ALLOW_GZIP
(which normally stops content length from resolving) without
setting FLAG_ALLOW_CACHING_UNKNOWN_LENGTH.
It seems like a good idea to flip the default at this point,
and explicitly disable caching in the one case where we want
that to happen.

If we prepare a deferred media period before the actual timeline is available,
we either prepare with position zero (= the default) or with a non-zero
initial seek position.
So far, the zero (default) position got replaced by the actual default position
(including any potential non-zero window offset) when the timeline became known.
However, a non-zero initial seek position was not corrected by the non-zero
window offset. This is fixed by this change.
Related to that, we always assumed that the deferred media period will the
first period in the actual timeline. This is not true if we prepare with an
offset (either because of an initial seek position or because of a default
window position). So, we also determine the actual first period when the

This was only needed temporatily until we could ensure that the player always
provides a BandwidthMeter.

This bandwidth meter is then forwarded to the track selection and as a transfer
listener to media and data sources.
When no bandwidth meter is specified in the ExoPlayerFactory methods, a static
singleton instance will be used.

After [] we support default font size for TTML, relative to the cellResolution of the document. However, this introduced a bug that makes TTML font-size in such case always follow the cellResolution font size, even when SubtitleView.setApplyEmbeddedStyles(false) and SubtitleView.setApplyEmbeddedFontSizes(false) were used.
This CL updates the fix so that the default font-size using cellResolution works in the same way as other embedded styles, and can be turned off using setters from SubtitleView.

That allows to add listeners after the BandwidthMeter has been created which is
helpful as the BandwidthMeter instances are often long-lived static instances.
