Currently, we sometimes apply new playback parameters directly and sometimes
through the list of playbackParameterCheckpoints. Only when using the checkpoints,
we also reset the offset and corresponding position for speedup position
calculation. However, these offsets need to be changed in all cases to prevent
calculation errors during speedup calculation[1].
This change channels all playback parameters changes through the checkpoints to
ensure the offsets get updated accordingly. This fixes an issue introduced in
31911ca54a.
[1] - The speed up is calculated using the ratio of input and output bytes in
SonicAudioProcessor.scaleDurationForSpeedUp. Whenever we set new playback
parameters to the audio processor these two counts are reset. If we don't reset
the offsets too, the scaled timestamp can be a large value compared to the input
and output bytes causing massive inaccuracies (like the +20 seconds in the
linked issue).

Before this change we'd release the audio track and create a new one as soon
as audio processors had drained when reconfiguring.
Fix this behavior by stop()ing the AudioTrack to play out all written data.

We currently handle most the control code logic after handling special
characters. This includes filtering out repeated control codes and checking
for the correct channel. As the special character sets are control codes as well,
these checks should happen before parsing the characters.

1. Only output video starting from a keyframe
2. When calculating the timestamp offset to adjust live streams to start
at t=0, use the timestamp of the first tag from which a sample is actually
output, rather than just the first audio/video tag. The test streams in
the referenced GitHub issue start with a video tag whose packet type is
AVC_PACKET_TYPE_SEQUENCE_HEADER (i.e. does not contain a sample) and whose
timestamp is set to 0 (i.e. isn't set). The timestamp is set correctly on
tags that from which a sample is actually output.

This permission has normal access right and can't be revoked by the user.
However, an app can choose to revoke it when using ExoPlayer, e.g. if
no network is required and the app doesn't want to list this permission.
Support this use case by gracefully catching the exception in the relevant
places.

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.

We are currently queuing periods in a way such that the new start position
lines up with the end of the previous period (to ensure continuous playback).
However, if the start position of the new period is larger than the total of
all previously played period durations, we may end up with negative renderer
timestamps when seeking back to the beginning of this new period. Negative
timestamps should be avoided as most decoders have problems handling them
correctly.
This change forces a renderer reset if we detect such a seek to a negative
renderer time and also resets the renderer offset to 0 every time all
renderers are disabled, as this is the only time where we can savely change
the offset of an existing media period.
Also, if playback starts with an ad, we choose the content position as
renderer offset to prevent the whole issue from occurring for the seek-behind-
midroll case.

It's currently very difficult to actually set a reason for track selection
triggered by a SelectionOverride. It would require creating a new custom
TrackSelection.Factory where the reason gets injected somehow before the
override is specified on the player.
Simplify this whole procedure by allowing to set the reason directly and
forward this reason to all fixed selections created based on this override.

The flag in ExoPlayer.prepare is documented as keeping the current window

but the position is not reset.
Using the initial seek position instead ensures we actually use the window

Add max video size workaround for Amlogic decoder.
The Amlogic awesome decoder reduces the video size of interlaced videos by half
if the internal configuration isn't force reset with new maximum input size
values. The product of these new values must exceed 1920x1088 to force the

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.

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.

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.

- 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
