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).

As part of pausing DefaultAudioSink, its position-related fields are reset. If

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.

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.)

internal player using a null timeline while ExoPlayerImpl keeps the previous

Up to now we use a boolean "preventListenerNotification" to suppress updates
while other operations are still in progress. This ensures, for example, that
only one initial timeline is issued even for multiple child sources.
As soon as we allow to reuse the same instance, it becomes increasingly difficult
to manage this manual listener notification suppression. Therefore, this change
schedules an update as a new message on the playback thread immediately after the
current message. This way, we also ensure that all simultaneous updates within one
looper message iteration are reported together.

If an exception is thrown in an IMA callback it crashes the process with lots of
logging from WebView (including several stack traces, etc.). This change wraps
ImaAdsLoader code that might throw, skips any remaining ads (as the errors are
not recoverable, in general) and notifies a new load error callback so that the
application can implement its own handling. The intention is to make the loader
robust to unexpected requests from IMA and avoid crashes.
Also handle IMA loading an ad in an ad group that has no available ads. In rare
cases IMA will try to load an ad for which an error was previously notified, so
this drops those load requests allowing playback of the content to continue.

All media periods are part of a queue of windows buffered and played by
ExoPlayer. When repeating windows, the current MediaPeriodId is insufficient
to distinguish between the repetitions of the same period. This makes it hard
to see to which media period load events belong to, and it is also difficult to
determine whether two media periods belong to the same logical window or
whether they are part of different repetitions of the same window.
Therefore this change adds a unique sequence number to each window in the
sequence of windows and this sequence number is saved as part of the
MediaPeriodId.

Releasing the player released the internal playback thread once renderers were
released. Releasing a MediaPeriod queued a Loader.ReleaseTask on the loading
thread which would post back to the playback thread. If the playback thread had
been quit by the time this happened, the release task wouldn't be run.
Release on the loading thread instead of the playback thread. This avoids
needing to block releasing the player until the loading threads have ended, and
ensures that release tasks will run eventually. As part of this change,
ExtractorMediaPeriod's call to Extractor.release will now run on the loading
thread (which means that all Extractor methods are called on that thread) and
other cleanup in ReleaseCallback will run on the loading thread instead of the
playback thread.
