Its only real purpose is to encapsulate a download ID, but it doesn't actually save
any code, and arguably makes it more complicated by having multiple lists of
Downloader instances, indexed by key, and also because it's another (undocumented)
class to understand.
This CL retains the multiple Downloader lists, but they will be flattened in a
child CL.

This is equivalent to the method ExoPlayer provides. It's nice for consistency,
and for retrieving the looper from test code.

DownloadRunner.getDownloader was creating Downloader instances before the actual
DownloadManager under test would have created them. Tests were then asserting and
manipulating these Downloader instances, which is quite confusing. In particular
FakeDownloader.assertDoesNotStart() is an assertion on a Downloader instance that
only makes sense when called on an instance that DownloadManager would not have
created by itself.
This change replaces FakeDownloader.assertDoesNotStart() with an assertion on
DownloadRunner that no Downloader instance has been created.

- Assertion chaining is generally discouraged. For example, because it's harder
to determine which assertion failed given a line number.
- Also removed chaining of the form obj.actionX().assertY(), because it's easy
for someone editing the test to accidentally delete actionX() when deleting
assertY(), where-as actionX() may often be important for subsequent assertions.

- Remove assertReleased and replace it with a proper condition variable
that's opened when Downloader.download or Download.remove finish. As
far as I can tell assertReleased was basically implementing "sleep for
10 seconds after the Downloader starts". Note fixing this properly
also makes the tests run much faster!
- Use ConditionVariable instead of CountDownLatch(1).
- Use AtomicInteger instead of volatile int because it's clearer and
allows removal of explanatory comments.
PiperOrigin-RevId: 308819204
- Improve documentation explaining the benefits of ExoPlayer's ConditionVariable
over the one that the platform provides
- Allow Clock injection
- Create TestUtil method for obtaining a ConditionVariable whose block(long)
method times out correctly when used in a Robolectric test
- Add basic unit tests for ConditionVariable

A previous change added these getters to CacheDataSource, but it can
also be useful to retrieve these components directly from the factory.
This is useful for tasks where we're going to need to build multiple
CacheDataSource instances (e.g., to make requests in parallel), and
also need to operate directly on the same components. It's a bit more
natural to retrieve them from the factory than from an arbitrary
CacheDataSource in this case, since it can avoid unnatural code where
you create a CacheDataSource instance earlier than you would otherwise
just to use its getters, and/or create one just to use its getters and
then throw it away.

- Executor is a superclass of ExecutorService, so this is arguably a little
more flexible.
- It removes the need to use null for direct execution, because Runnable::run
is a direct executor that can be trivially used instead.
- Removing the error-prone "cannot be a direct executor" restriction in the
parallel version of SegmentDownloader requires not relying on the futures
returned from ExecutorService.submit() anyway.

Currently, this method is only supposed to be called before removing
the listener from the player or when releasing the player.
If called at other times, it will throw an exception later when
a playback session is ended automatically.

The method is used to finish a brief "seeking" state that can be removed entirely
now state changes for seeking are masked.

Unmarshal from json to MediaItem instead of Sample. Further the playlist
of MediaItems is converted to Intent extras which are read by the
PlayerActivity.

While most ExoPlayer code parsing ByteBuffers is called with buffers in big
endian, in certain situation, buffers in little endian are used too.
MediaCodec produced ByteBuffers are in little endian, while buffers
receive from the sources are in big endian (ByteBuffer's default).
As a result, some code called from AudioSink in passthrough parsed
bytebuffer in little endian. This is not correct because those
format are specified in BigEndian.
Changing the endianness of the ByteBuffer returned from MediaCodec
would impact a lot more code that can currently be tested in the
current COVID lockdown situation.
As a result, this patch instead make the parsing code independent
of the ByteBuffer.order() set. All the code that is called from
DefaultAudioSink now parses the buffer explicitly in Big Endian.
Additionally, the MPEG big endian header data of size 4 bytes was
retrieved with ByteBuffer.get, which only returns one byte.

The first session should only be created once we have the media items
and/or called prepare. Otherwise the first session is created with
an EventTime having an empty timeline making it less useful.

Part of what makes these tests hard to deal with (imo) is being
unable to easily run a specific config, or seeing exactly which one
failed (because you always see only the first failure).
I put the parameters as a method on ExtractorAsserts to
reduce the boiler-plate required in each test class.
I'll migrate the extension FlacExtractorTest in a follow-up CL

Something that helps a constructor always seemed a bit strange.
It's now possible to use CacheDataSource.Factory directly instead.
PiperOrigin-RevId: 307661930
In the same way it made sense to tie CacheKeyFactory and CacheDataSource
together in
7ea83d7167,
it makes sense to tie the PriorityTaskManager to the CacheDataSource as
well. This prevents error prone scenarios where one can end up being
passed around without (or with the wrong instance of) the other.
This change also internalizes use of PriorityDataSource directly into
CacheDataSource, rather than requiring the caller to chain things
themselves.

The sample timestamps are currently rounded to milliseconds, only to
be multiplied by 1000 later. This causes rounding errors where the sample
timestamps don't match the timestamps in the seek table (which are already
in microseconds).
