This changes fixes issue #7181.  Removing CEA-608 captions that timeout after 16 seconds without a
clear.

This makes the distinction more clear between the methods that test
a specific behaviour (and are meant to be used with parameterized
tests) and those that test everything in one go.

Also add a TODO to FlacExtractorTest to migrate it when we can

Also mark the two assertOutput methods private, to make the API surface
smaller.

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.

LoadEventInfo needs to also be sent to the LoadErrorHandlingPolicy.

This better supports custom listener types defined by MediaSource
subclasses.

This is just some trivial cleanup to get things into a better state to
implement parallel segment downloads.

The MediaSessionConnector gets a Bundle passed to the MediaSession.Callback
from the framework which can be null. This needs to be properly annotated
with @Nullable.

This avoids the non-parameterized tests being run repeatedly for every
combination of parameters.

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
https://github.com/google/ExoPlayer/commit/7ea83d7167d0b021fb280fca2b5dfa4a5616b5c1,
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).

This change generalizes the concept of "reading parameter sets" to
"reading prefix NAL units", ahead of a change that will treat AUD
and suffix SEI NAL units in the same way.

The change also introduces some static isXxxNalUnit methods for
clarity.

Currently we assume these are "start", "center", "middle" or "end",
which was correct in a previous draft of the spec:
https://www.w3.org/TR/2014/WD-webvtt1-20141111/#dfn-webvtt-text-position-cue-setting

The released spec uses "line-left", "center" and "line-right":
