I was considering putting this directly in DefaultHttpDataSource, however:
- We'd need to modify at least OkHttpDataSource as well. I'm not sure whether
Cronet follows this type of redirect automatically or not.
- HttpDataSource instances don't know how they're going to be used, so it's
probably correct that they behave like the underlying network stack.

Currently, pending stream offset changes are kept until an output buffer
timestamp surpasses the next pending stream offset. However, this is
problematic if the next stream offset overlaps with the current output
buffer sample times (e.g. because the next stream starts at a non-zero start
time).
To correctly time the switch to the next stream offset, this change keeps
the timestamp of the last queued input sample as switch point. And we only
switch to the new offset after an output sample timestamp reached this switch
point.

In MatroskaExtractor TrueHD audio samples are joined into larger chunks. For
some streams the resulting chunked samples seem never to start with a syncframe.
This could result in playback of TrueHD streams getting stuck after seeking
because we could never read a syncframe at the start of a sample to determine
the sample size.
Instead of expecting to find a syncframe at the start of a sample, search for it
within the sample, to fix this issue.
Note: this means that we may search a few thousand bytes to find the sample
size, but the cost is only incurred for the first audio sample read.

Previously the SonicAudioProcessor and SilenceSkippingAudioProcessor would track
their pending playback parameters and only apply them in flush(). Having the
values only take effect once flushed made the processors a bit more difficult to
use, especially because the value returned by isActive wouldn't update
immediately.
Make DefaultAudioSink only set the new speed/pitch/skip silence setting after
the audio processors have drained. This means it's no longer necessary to keep
track of pending parameter values and also fixes a bug where initial playback
parameters weren't applied because the audio processors weren't flushed while
uninitialized before DefaultAudioSink called isActive() on them.

Video renderers assume that the player position is advancing linearly while in
the started state. MediaCodecVideoRenderer schedules frames for rendering in the
future in the expectation that the player position is advancing.
This assumption is not currently true when using a position from the AudioTrack:
the player position can be fixed for (in the worst case) up to about 100 ms
before it starts increasing. This leads to an effect where the first frame is
rendered then a few other frames are rendered, then there's a pause before
frames start being rendered smoothly.
Work around this issue by checking whether the position has started advancing
before scheduling frames to be rendered in the future.
It might be preferable to make the audio renderer only become ready when its
timestamp can start advancing, but this is likely to be complicated.

This adds two options to the ClippingMediaSource which allow proper clipping
of live streams:
1. The clipping stays fixed relative to already created media periods. That
means that playback actually progresses through the clipped media and
eventually reaches the end of the clipping. The window is also marked
as non-dynamic to let playback end in this case.
2. Allow to specify a clipping duration relative to the default position to
be able to specify the duration of live stream which is to be played.

This change is being made as a precursor to a subsequent change
where creating the TrackSelectorResult will move from
MappingTrackSelector to DefaultTrackSelector. DefaultTrackSelector

Before this change, HlsMediaSource timelines had a period starting at the epoch.
For VOD streams the window position in the period was the program date time.
This change makes period and initial window positions match. For live streams
the window position advances as segments are removed, so its position in the
period is the difference between the initial program date time and the program
date time of the latest playlist.
This also makes it possible to insert ads in VOD HLS content with program date
time, as the period and window are now aligned.

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.

So far this wasn't possible because Robolectric's Looper and MessageQueue
implementations have multiple shortcomings:
1. The message loop of new HandlerThreads is an not an actual loop and
scheduled messages are executed on the thread the message is enqueued
(not the handler thread).
2. The scheduler used to replace the message queue is synchronizing all its
methods. Thus, when a test attempts to add messages to a Handler from
two different threads, it may easily run into a deadlock.
3. The scheduler doesn't correctly emulate the order of messages as they
would be in an actual MessageQueue:
a. If the message is enqueued on the handler thread, it gets executed
immediately (and not after all other messages at the same time).
b. The list of messages is always re-sorted by time, meaning that the
order of execution for messages at the same time is indeterminate.
4. Robolectric's SystemClock implementation returns the current scheduler
time of the main UI thread. So, unless this scheduler is used to add
messages in the future, the SystemClock time never advances.
This CL adds two helper classes which extend and replace Robolectric's
ShadowLooper and ShadowMessageQueue.
1. We intercept messages being enqueued or deleted in the message queue.
Thus Robolectric's faulty scheduler gets never used. Instead, we keep
a blocking priority queue of messages, sorted first by execution time
and then by FIFO order to correctly emulate the real MessageQueue.
2. We also keep a list of deleted messages to know which messages to ignore
when they come up in the looper.
3. When a new Looper is started, we override the dummy loop to an actual
eternal while loop which waits for new messages, checks if they haven't
been deleted, and runs the messages (similar to what Robolectric's
MessageQueue would have done at this point).
Because we don't actually use the main UI thread in our tests, we can't rely
on the SystemClock to progress in any sensible manner. To overcome this issue,
we can use the auto-advancing FakeClock also used for the simulation tests.

This fixes a very specific case where the data read has non-cached gaps
and a read-only CDS switches to read from upstream in a gap then the
cached data is deleted. When the CDS reaches the end of the gap, it
tries to open the next source. As there is no cached data, it tries to
continue with the already opened upstream data source but as it reached
end of the gap range, the code starts looping.
Also fixes infinite lock which occurs when in the previous case CDS isn't
readonly. It locks the content while filling the gap in the cache. At the
end of the gap, as the following data is deleted it tries to lock the
content for writing but the content is already locked by itself.
The last fix is preventing removal of CachedContent entry from

If one stream is reading ahead more than a threshold (default: 10 seconds),
the extractor continues reading the other stream even though it needs
to reload the source at a new position.

ChunkSampleStream.seekToUs assumes that if we can seek within the
primary sample queue, we can also seek within the embedded queues.
This assumption can be violated fairly easily if discardBuffer is
called with toKeyframe=true, since this can cause samples to be
discarded from the embedded queues within the period for which a
seek in the primary sample queue will succeed. This change fixes
the issue.

Whilst the previous behavior was WAI and had the advantage of
updating the position to be more exact when known, there were
a couple of disadvantages:
1. If seeking to the very end of a period in a playlist when
paused, the position adjustment could trigger a position
discontinuity to the next period.
2. We de-duplicate seeks to the current playback position.
The position adjustment can prevent this from being
effective. This is particularly important with the new
SeekParameters support. When seeking to nearest sync point
it's often possible to de-duplicate seeks, but we cannot
do so if the playback position adjusts away from the sync
point's time.

draining playback parameters completed. Draining playback parameters are cleared
in reset(), so if parameters were set while paused then the sink was quickly

captions fetcher architecture.
1. ManifestlessCaptionsMetadata
Other captions fetchers must first fetch a manifest (HLS or manifest) to
discover captions tracks. This process does not exist for manifestless. All
we need to do is scan the FormatStream's for the right itag, so this is an
all-static class.
2. ManifestlessSubtitleWindowProvider
Once a captions track is selected, a subtitles provider is instantiated. This
is the main interface used by the player to retrieve captions according to
playback position. This class stores fetched captions in a tree index by time
for efficient lookups. Background captions fetches are used to populate
the tree.
3. ManifestlessCaptionsFetch
Captions are fetched one segment at a time. One instance of this object
is required per fetch. It performs a blocking fetch on call(), and is
intended to be submitted to a background-thread executor.
4. ManifestlessCaptionsFetch.CaptionSegment
This is the result of the caption fetch. These values are used to populate
the captions tree.
Manifestlessness
The initial request is always a headm request. There is a separate tree
of every segment indexed by start time. This tree is used to improve
manifestless sequence number calculation. Once we have data for the current
timestamp, we walk forward through the tree to find the next unfetched
sequence number, and fetch that.

We've found that in our production environment, the AAC stream's timestamp exceeds the 33bit limit from time to time, when it happens, `peekId3PrivTimestamp` returns a value that is greater than `TimestampAdjuster.MAX_PTS_PLUS_ONE`, which causes a overflow in `TimestampAdjuster.adjustTsTimestamp` (overflow inside `ptsToUs`) after playing for a while . When the overflow happens, the start time of the stream becomes negative and the playback simply stucks at buffering forever.
I fully understand that the 33bit is a spec requirement, thus I asked our stream provider to correct this mistake. But in the mean time, I'd also like ExoPlayer to handle this situation more error tolerance, as in other platforms (iOS, browsers) we see more tolerance behavior.

Now, media chunks may be discarded later on or in batches, leaving the

out whether a new media source has been prepared or the current source
refreshed dynamically was impossible without tightly coupling the player

Currently for a DASH ChunkSource that consists of multiple sub-streams, we
always use a CompositeSequenceableLoader, which only allows the furthest behind
loader or any loader that are behind current playback position to continue
loading.
This changes allow clients to have more flexibility when deciding the loading
strategy:
- They can construct a different kind of composite SequenceableLoader from
the sub-loaders, and use it by injecting a different CompositeSequeableLoaderFactory accordingly.

This change makes sure progress is being made before reporting
a discontinuity. Else in cases like having no network and
playing a live stream, we allow the discontinuity to be read
each time an internal retry occurs, meaning it gets read
repeatedly. This does no harm, but is noisy and unnecessary.
We should also not allow skipping whilst there is a pending
reset or discontinuity notification, just like we don't allow
reads.

This is a step toward retaining a back-buffer in a way that
works for all MediaSource implementations. It's not possible
to adjust the discardBuffer calls in ExoPlayerImplInternal

are to:
1. Find an appropriate place to specify the back buffer value,
to be passed to the discardBuffer calls. I guess the
LoadControl is the appropriate place to define such values.

When the renderer media clock source read its stream to end but is not ready,
this means one of two things. Either the next period is not prepared yet and
we need to stop the renderers and buffer until it's prepared, or we are
waiting for another track in the current period with a uneven (longer)
duration.
The second case was already covered by this if condition and uses the standalone
clock instead to continue.
The first case now also uses the standalone clock, but it doesn't make a
difference, because both clocks are stopped and still synchronized.

3. Ignore MSG_POSITION_DISCONTINUITY during preparation
4. Correctly set masking variables at start of preparation, and use them
Once this change goes in, PlaybackInfo will contain timeline, manifest
and position, which should always be self-consistent with one another.
The next step would then be to move a bunch of logic in ExoPlayerImpl
that derives state from timeline and position into PlaybackInfo, and
split that into its own top level class that can be easily tested to make
sure it never IndexOutOfBounds.
I think we could also replace the masking variables and instead just assign
a new PlaybackInfo to the playbackInfo variable whenever we're doing
something that requires masking. This should be possible because we no
longer update playbackInfo whenever we have pending acks. It would
require allowing PlaybackInfo to mask the window position internally when
the timeline is empty, but I think this is ok, and again is something we
could test pretty easily.

This change fixes various issues:
- MobileHarness sometimes allocated devices with SDK < 16. As we have no tests running
on these SDKs, a new dimension filter for the mobile_test target ensures that only
devices with SDK >= 16 are selected. A similar filter for SDK version is also added
to the ABR playback tests to ensure no old devices are selected.
- DRM specific tests are skipped for Api < 18, but were not able to run because the
DashTestRunner class tried to link to the MediaDrm constructor. Moved the
constructor to a seperate Builder class to allow execution on Api levels 16 and 17.
- DashWidevineOfflineTest also tried to access code for Api >= 18 without checking
the current level.
- Action implementations which are waiting for events did not ensure that they have a
nextAction to wait for. This caused NullPointerExceptions when this next action was
scheduled.
- DefaultDrmSession always restored the offline keys when a new license was requested,
even if the keys were already restored. These repeated slow calls to restoreKeys

- SampleRate

For NoSampleRenderer, we should avoid doing this: skipping ahead for such

SampleStream), and it will change the provided rendererOffsetUs while the

which prevents switching from ever happening. So we will provide the
durationToLiveEdgeUs to AdaptiveTrackSelection in live streaming case,
so it can handle this edge case.

The release callback handler in Loader might not be alive
anymore. Catch this case to prevent warnings about sending
messages on dead threads.

Remaining instrumentation tests either use android.os.Handler or rely on assets.
In the latter case, the tests are difficult to migrate due to differences
between the internal and external build systems, and configuration needed in
Android Studio. In addition, SimpleCacheSpanTest remains as an instrumentation
test because it fails due to a problem with string encoding on the internal
build (and two other tests in its package are kept with it because they depend
on it).
This test removes a dependency from testutils on Mockito, as a different
version of Mockito needs to be used for instrumentation tests vs Robolectric
tests, yet both sets of tests need to rely on testutils. Mockito setup is now
done directly in the tests that need it.
Move OggTestData to testutils so it can be used from both instrumentation and
Robolectric tests.
It may be possible to simplify assertions further using Truth but this is left
for possible later changes.
