If the AudioTimestamp was sampled before play() was called, it was incorrectly
returned to the caller for sanity-checking. Fix this behavior by dropping the
timestamp internally in the AudioTimestampPoller.

This change enables feeding decoders from the closest sync frame
before a specified seek position, where-as previously we'd
always feed decoders from the start of the chunk. This avoids
decoding and discarding many audio samples during each seek. The
same benefit also applies to video chunks containing more than
one key-frame.

This adds callbacks for creating, releasing, and starting to read from media
periods.
Such events allow listeners to keep a list of active media periods. This is
useful to determine when no further events for a certain media period are
expected. It also allows listeners to associate renderer events unambigiously
with a reading media period.

This was only needed to ensure a ClippingMediaSource can provide samples from
a key frame before the clipping start time. Now the ClippingMediaSource will
not report negative timestamps, this workaround can be removed.

This will never happen in practice, since CEA608 shouldn't be encrypted (and we
can't handle it if it is), but in theory appendSampleEncryptionData can be called,
then skipFully can throw when applying the CEA608 transformation, then when
retrying appendSampleEncryptionData will be called again for the same sample.
appendSampleEncryptionData consumes from trackFragment.sampleEncryptionData, and
so the second time around data is being consumed one sample ahead.

The ad events are independent of the other media source events. Also,
registering the listener to the internal ad media sources will report the
regular media source events twice: once directly (with a non-ad media period
id) and once through the wrapping ads source (with the correct ad media period
id).

Add logic to poll AudioTimestamp at different rates depending on when
playback starts and how the audio timestamp advances.
This fixes a pause about 500 ms after starting playback that occurs on some
devices and also makes our polling interval match the recommendations of the
AudioTrack documentation.

When creating DeferredMediaPeriods, we don't know the actual timeline yet and
thus the default position is also unknown. We can still forward the correct
default position by forwarding it the deferred media period as soon as it
becomes known.

As part of pausing DefaultAudioSink, its position-related fields are reset. If
the audio timestamp API was in use, this results in falling back to the
getPlaybackHeadPosition API, which (on some devices) can lead to a jump in the
reported position.
Sample the position before pausing instead of after, to avoid this jump.

compositions. The composite media source has the chance to correct the

Currently, whenever the clipping is updated, we move the time frame of the
clipped period to start at 0. This causes problems when we are already playing
this period and the renderer position does no longer match the stream
positions.
This change keeps the time frame of the clipped media period as it is and
instead specifies the offset of the window in the period.

DefaultAudioSink had a lot of code related to tracking the position of the
underlying AudioTrack, and working around issues with the position APIs.
Move this code to a separate class responsible for position tracking. This is in
preparation for improving the audio timestamp polling behavior.
This change is intended not to cause any behavior changes.

treated differently.

When creating a new AC-3 passthrough AudioTrack the position
may advance from an old AudioTrack's position. The workaround
checked for the playback head position returning to zero, but
a subsequent change meant that we'd always start writing data
to the new track immediately (rather than waiting for its
position to 'stabilize' at zero).
Fix the issue by using the AudioTrack position directly. (Nb.
this doesn't handle the case of the stale position before
unwrapping being zero, but it is very unlikely to occur.)
