Previously, we had separate MSG_SET_SURFACE and
MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER messages for
setting different types of supported output. Use of these
constants to switch between outputs during use of a player
was confusing because not all video renderers support both
message types.
To switch from VideoDecoderOutputBufferRenderer to a Surface,
it was sufficient just to send MSG_SET_SURFACE, since all
video renderers support this and clear any other output that
might be set. Conversely, to switch in the opposite direction,
just sending a MSG_SET_VIDEO_DECODER_OUTPUT_BUFFER_RENDERER was
not sufficient, because not all video renderers handle this
message to clear any previous output. Hence it was necessary to
explicitly clear a previously set surface using a separate
MSG_SET_SURFACE message. Passing two messages to switch the
output may prevent renderers from implementing the output switch
efficiently.
This change passes all outputs using a single message type, and
requires that all renderers treat unsupported outputs as though
null were passed (i.e., they clear any existing output). There
are some other miscellaneous improvements:
1. Non-surface outputs are now passed to onRenderedFirstFrame.
This fixes a bug in SimpleExoPlayer's onRenderedFirstFrame,
where previously it could not correctly equality check the
output corresponding to the event to its current output in
the VideoDecoderOutputBufferRenderer case.
2. Fix SimpleExoPlayer to report surface size changes for the
VideoDecoderOutputBufferRenderer case. Even though the
surface is rendered to indirectly in this case, we can still
query (and listen to changes to) the surface's size.

If this condition isn't true, the player may enter a cycle of discarding
and reloading the same format. As minDurationToRetainAfterDiscard is a
parameter likely left at its default, and minDurationForQualityIncrease
is likely adjusted more often, we correct the value in the problematic
case and log a warning instead of asserting it outright to prevent
unnecessary app breakages.

Prior to this change, there were some unrealistic quirks in
our Robolectric tests. For example, onRenderedFirstFrame would

improvements being made to how outputs are set on video

This was added in 9609af3c23 as part of a LSC.
The RequiresNonNull annotation doesn't work anymore (it doesn't
recognize the outer class member and instead tries to find
the same variable on the inner class). So instead of suppressing
the warning of the non-fulfilled precondition, we can just
check the non-nullness directly and remove the precondition.
PiperOrigin-RevId: 367593941
The main change here is that VideoDecoderGLSurfaceView now implements
VideoDecoderOutputBufferRenderer directly. This avoids SimpleExoPlayer
having to cast to VideoDecoderGLSurfaceView, which will be necessary
if VideoDecoderGLSurfaceView is moved to the UI module. Instead, the
player can cast directly to VideoDecoderOutputBufferRenderer, which
could be moved to the Common module.
The renderer is also moved to be an inner class, since it's not used
anywhere else and since doing this makes it a little easier to move
things around.

We added a source that allows mixed placeholder and non-placeholder
periods, but have no way to denote that in the Timeline because the
placeholder flag only exists on Window level. This causes a bug if
the first item in a concatenation has a window-period offset and the
player can't detect whether it's still a placeholder or not.
Adding this flag to Period allows the player to detect this reliably.
In addition we need to make sure that re-resolving pending positions
only happens for the first placeholder period where the window-offset
can actually change. As all subsequent periods have to start at position
0, so they don't need to be re-resolved (and shouldn't).

If the player is created on a background thread (which is allowed
as the only exception to the access-on-one-thread-only rule), it
may happen that a callback on the main thread tries to access the
player before the constructor even finished. This is dangerous and
can cause exceptions due to uninitialized variables.
To solve this, we can make sure that every player access is blocked
until the constructor finished. Blocking is safe because the
constructor itself is not doing any blocking work or acquiring locks.
The thread verification method is already called on every entry
point to the player, so we can reuse the same method for checking.

- The exact old position is also useful for media time history logging.

The exo_controls_background view is supposed to fill its parent,
and so previously used match_parent to do this. However, if the
parent uses wrap_content for its own dimensions, the constraints
being specified become somewhat ambiguous. The parent is supposed
to be sizing itself to wrap its children, and one of the children
is supposed to be sizing itself to match the parent.
Intuitively for this case, you'd hope that the layout logic would
size the parent to wrap its other children, and that the
match_parent child would then fill the parent with its determined
size. That's not what happens, and instead the parent ends up
expanding to occupy all of the space available to it.
This commit sets the exo_controls_background view's dimensions
to be 0dp in the layout, to stop it from influencing the size of
the parent. It's then expanded to fill the parent in code.

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.

When we add DRM pre-acquire support to SampleQueue, we'll dispatch
twice the number of acquire and release events. This is slightly
confusing, since there's the same number of
DrmSessionManager#acquireSession() calls.
We can mitigate this by only dispatching each acquire and release
event to at most one EventDispatcher.
This also changes the events fired when playing a stream with both audio
and video encrypted with the same keys (even without pre-acquisition).

release events.
After: The EventDispatcher will see 1 acquire, 1 key load and 1 release.

This is a no-op assuming the class is always used correctly.

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.
