The BasePlayer implementation of add/remove
Listener knows about Components.
As those are removed from the Player
interface, the implementation of those
methods needs to be moved down in Player
implementations.
This commit makes no functional change.

All Player methods should throw
NotSupportedException.
Making it abstract prevents the compiler catching
non implemented methods.

Null was an alias for DEFAULT. Remove this for nullness
safety in the API.
The ExoPlayer implementation still checks for null and
replaces it by DEFAULT, so this is ABI compatible.

- Update the three `HttpDataSource` implementations to use the
Content-Range response header to determine when this is the
case. The Content-Range header is included when the status
code is 416. See [here](https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/416).
- Update `ByteArrayDataSource` to conform to the requirement.
- Update `DataSourceContractTest` to enforce the requirement.

- SampleQueue.peek is replaced with SampleQueue.read with
FLAG_PEEK. This also exposes peek functionality through
SampleStream.
- Use of DecoderInputBuffer.isFlagsOnly is replaced with
FLAG_OMIT_SAMPLE_DATA. This flag can be used with or
without FLAG_PEEK, where-as previously the read position
would never be advanced for an isFlagsOnly buffer.
- formatRequired is replaced with FLAG_FORMAT_REQUIRED.

Assert that opening the DataSource at the end of the resource
results in only RESULT_END_OF_INPUT being read.
open() and read() are still permitted to throw, although this
permissiveness will be removed in subsequent commits.

TransferListener has the contract to have exactly one onTransferEnd per
onTransferStart, so the test can both assert that onTransferInitializing
is called, but not onTransferEnd (even after calling close).

MaskingMediaSource needs to resolve the prepare position set for a MaskingPeriod
while the source was still unprepared to the first actual prepare position.
It currently assumes that the period-window offset and the default position is
zero. This assumption is correct when a PlaceholderTimeline is used, but it
may not be true if the real timeline is already known (e.g. when re-preparing
a live stream after a playback error).
Fix this by using the known timeline at the time of the preparation.
Also:
- Update a test that should have caught this to use lazy re-preparation.
- Change the demo app code to use the recommended way to restart playback
after a BehindLiveWindowException.

- Split text emphasis mark and style into two IntDefs
- Represent textEmphasis="none" with a span rather than null
- Fixed bugs in the style parsing logic
- Refactor TextEmphasis class to support different ordering of styles
- Merge RubySpan.Position and TextEmphasisSpan.Position
- Remove TTML constructs from Spanned classes
Includes fixes for the HTTP implementations, which previously
broke this contract specifically in the case when a server
responds to a range request with a HTTP 200 response. To fix
this case, skipping to the requested position is moved from
read() to open(). As a side effect, this nicely simplifies
CronetDataSource!

Given we're proposing to make reading from the end a non-error case,
it's important to check that we return the right thing from open(),
and that we read the right thing (i.e., nothing) once opened.
For now, this test allows quite a bit of permissiveness, in line
with other related tests. This will be tightened up in due course.

Currently, this only asserts that *if* an exception is thrown, it
must be a position-out-of-range exception as determined by
DataSourceException.isCausedByPositionOutOfRange.
Issue: #7326
PiperOrigin-RevId: 359092124
Assert that an exception is not thrown from DataSource.open
if the DataSpec's start position is valid but its end position
extends beyond the end of the data.
HTTP based DataSource implementations have no good way of
knowing when this is the case, so it makes sense to make this
the required behaviour, rather than requiring an exception to
be thrown or allowing both.
There are also use cases where the caller may want to use the
end position as an upper bound, without knowing for sure how
long the content is. An example of this use case is wanting to
pre-cache the first N bytes of a stream. This implies that any
exception should be thrown after reading to the end of the
data, rather than preemptively in open.

- If DataSource.close fails then it's unknown whether the underlying file was
written to the cache. We should assume that it has not been.
- Always re-query cachedBytes at the start of CacheWriter.cache, since its
current value may be incorrect if a previous failure was the result of a
file not being written to the cache.
PiperOrigin-RevId: 359039109
- Make it a property of the DataSource, not of the resource.
- Apply it only when a contract test reads using an
unbounded DataSpec.

This type is different to the selection reason, which is
dynamic (i.e., corresponds to the individual selected track,
which can change during playback). The static type is
exposed via TrackSelection, where-as the selection reason
will be internal to the core (i.e., player) module.

This parameterized test execute a single playback with a variety of
specified network conditions, user country and network types, and then
compares some basic ABR performance data against a dump file to detect
changes.

We currently block the loading thread until the calculated load
time has past and then unblock again by a message sent from the
playback thread. However, because the loading thread itself is not
using a Looper and runs freely, we don't control when the short
calculations on the loader thread that determine how long we have
to wait are happening, and we also don't control how long it takes
to start and stop this thread.
To solve these problems and to make the playback deterministic we
can
1. Send a message on the playback thread to block until the loader
thread has started.
2. Block the playback thread whenever a loading thread is doing its
short calculation of wait times. The playback thread knows when it
can continue because loading either enter a new waiting state for
a simulated load time or loading is finished completely.
3. Also wait on the playback thread until the loader has shut down.
As this is waiting for a message on the playback thread, we can
achieve this by sending messages to ourselves at the current time
until the loader is shut down.
All 3 steps together ensure that the loading thread interaction is
compeltely deterministic when simulating bandwidth profiles with the
BandwidthProfileDataSource. As we need to notify the source before and
after the load started/finished, we also need a small wrapper for the
chunk source when running the playback.

Main improvement is to switch away from ExoPlayerTestRunner and to
split out the waiting component so that the same class can be used
from Robolectric tests in the future.
The only functional difference is that that BufferLengthLogAction
is removed completely because the data isn't used downstream and the
method of collecting this data is a bit arbitrary.

This can happen for instrumented tests that are run on a non-Looper
thread. If these tests send a message to a Looper thread to start the
test procedure, they should just triger the message directly as before.

- The order of sample stream (and thus the order in which loads are
triggered) currently depends on a Set and thus on the hash codes
of the objects that change with every run. Changing to a List solves
this problem.
- The FakeAdaptiveDataSet directly created a static Random (with random
seed) to compute the variation of chunk sizes. Changing this to an
injected Random object that can always be initialized with the same
seed also removed this randomness from the tests.
PiperOrigin-RevId: 353878661
This is achieved by only triggering one message at a time. After
triggering a message we send another to ourselves to know when the
following message can be triggered.
Other required changes:
- The messages need to be sorted correctly (by time and creation order)
- To prevent deadlocks when one thread is waiting for another,
we need to add new method to Clock to indicate that the current
thread is about to wait. This then allows us to trigger messages
from other threads in FakeClock.
- AnalyticsCollectorTest needed some adjustments:
- onTimelineChanged now deterministically arrives after the initial
timline is already known, so some of the period information changes
from window only to full period info.
- The playlistOperations test suffers from a bug that the first frame
is rendered too early and that's why we now get additional events.
PiperOrigin-RevId: 353877832
We currently only remove messages that have already been sent
to the actual Handler, not the pending ones that are only kept
in the FakeClock. Fix this by also removing matching messages
from the FakeClock list.
PiperOrigin-RevId: 353877049
Currently only delayed messages are handled. Change this to handling
all messages so that we have more control over their execution order.
This requires adding a new wrapper type for the Message to support
the obtainMessage + sendToTarget use case.
