When track is changed during playback, `playbackPositionUs` may be in middle of a chunk and `loadPositionUs` should be the start of that chunk. In this situation `loadPositionUs` can be less than the current `playbackPositionUs`, resulting into negative `bufferedDurationUs`. It translates to having no buffer and hence we should send `0` for `bufferedDurationUs` when creating new instances of `CmcdData.Factory`.

Otherwise, there's a memory leak of ~30MB, as this is never released.
This likely used to be considered released as part of what now became
`intermediateGlShaderPrograms`, but its release was missed after we split
`finalShaderProgramWrapper` out from the larger glShaderProgram list.

To prepare to move `inputColorInfo` from `VFP.Factory.create` to
`VFP.registerInputStream`, move all usage of `inputColorInfo` to be *after*
`registerInputStream`.
To do this, defer creation of `externalShaderProgram` instances, which require
`inputColorInfo`. However, we must still initialize `InputSwitcher` and OpenGL
ES 3.0 contexts in the VFP create, to create and request the input surface from
ExternalTextureManager.

The timestamp adjuster also estimates the number of wraparounds
of the 90Khz TS timestamp. It does that by assuming that a new
timestamp is always close to the previous one (in either direction).
This logic doesn't always work for duration estimates because the
timestamp at the end of the media is not close to the one at the
beginning and it may also never be less than the one at the beginning.
This can be fixed by introducing a new estimation model that assumes
the new timestamp is strictly greater than the previous one without
making the assumption that it has to be close to it.

When broadcasting a notifyChildrenChanged event, the task for legacy
controllers was sent to the broadcasting callback. This would
technically work, but because the subscription list is maintained
with specific controllers, the broadcast controller isn't subscribed
and hence the call wasn't executed.
This change calls the overloaded method for a specific controller
for each connected controller. Making sure (only) subscribed
controllers are notified.

Vertical and horizontal tile counts inside Format used by ImageRenderer
used to be required to equal 1 and were set to 1 regardless of what
the manifest said.
This change removes the above requirement and sets the tile counts to
the values from the manifest.

Using 0 as the unset prepare position is the root cause of a number of issues,
as outliine in the ExoPlayer issue https://github.com/google/ExoPlayer/issues/7975
The premise of this fix is that once the prepare override is used (the initial call
to `selectTracks()`) it is never needed again, so simply invalidate it after use.
Despite GL 3.0 not being required on API 29+, it is experimentally
determined to always be supported on our testing devices, on API 29+.
That said, still fall back to OpenGL 2.0 if 3.0 is not supported,
just in case.

`Mp4Writer` receives all the tracks/samples and then it adds them to
corresponding `Track` object. As the `Track` object is primarily to hold
track specific data and `Mp4Writer` is responsible for interleaving related
logic, the call to `doInterleave` should be with `Mp4Writer`. The `Track`
object should just act like a data holding class.
This will also help in reusing `Track` class for fragmented MP4 implementation.

An app that uses the `MediaSession` without a `MediaSessionService` may
want to connect a media notification controller on it own. To avoid apps
using a string literal, the key should be exposed as public.

The MP4 data in JPEG motion photos can contain multiple `video/hevc` tracks, but only the first is at a playable frame rate while the others are low-fps, high-res tracks designed for specific use-cases (not direct video playback).
ExoPlayer currently selects the unplayable track by default, because it
has a higher resolution. This change introduces a flag to
`Mp4Extractor` that results in the first video track being marked as
`ROLE_FLAG_MAIN`, and all subsequent video tracks `ROLE_FLAG_ALTERNATE`
- this then results in the playable lower-res track being selected by
default.

There is a bug in CompositionVideoSinkProvider where the rotation
effect is applied only on the first video and the same effect
is applied on subsequent videos without checking if the next
items in the playlist must be rotated.
The bug applies only on devices with API < 21.

We currently pause playback to prevent further progress while the
app thread runs assertion and triggers additional actions. This is
not ideal because we do not actually want to pause playback in
almost all cases where this method used.
This can be improved by keeping the playback thread blocked and only
unblock it the next time the app thread waits for the player (either
via RobolectricUtil methods or by blocking the thread itself). To
add this automatic handling, this change introduces a new util class
for the tests that can keep the list of waiting threads statically
(because the access to this logic is spread across multiple independent
classes).

Fix a bug where CompositingVideoSinkProvider.isInitialized() returns
true even after releasing the CompositingVideoSinkProvider.
PiperOrigin-RevId: 588481744
This change moves the instantiation of the CompositingVideoSinkProvider
out of MediaCodecVideoRenderer so that the composition preview player can
re-use the CompositingVideoSinkProvider instance for driving the rendering of
images.
The main point of the change is the ownership of the
VideoFrameReleaseControl, which decides when a frame should be rendered
and so far was owned by the MediaCodecVideoRenderer. With this change,
in the context of composition preview, the VideoFrameReleaseControl
is no longer owned by MediaCodecVideoRenderer, but provided to it.
This way, the CompositingVideoSinkProvider instance, hence the
VideoFrameReleaseControl can be re-used to funnel images into the
video pipeline and render the pipeline from elsewhere (and not
MediaCodecVideoRenderer).

The serializable form is used when we need to serialize the result into
bytes in the sample queue. The binder-based (ultimately
filedescriptor-based) form is used for
session/controller IPC, in order to avoid sending the bitmap bytes over
the IPC.

This helped me debug which bitmap was actually failing. Otherwise, you need to clear all bitmaps on the device relating to this test, then adb pull all bitmaps and see the last uploaded one to see, which is much more confusing.
