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.

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).

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.

Both the extension OPUS decoder and the OMX/C2 MediaCodec
implementations for OPUS and VORBIS decode into the channel
layout defined by VORBIS. See
https://www.xiph.org/vorbis/doc/Vorbis_I_spec.html#x1-140001.2.3
While this is technically correct for a stand-alone OPUS or VORBIS
decoder, it doesn't match the channel layout expected by Android.
See https://developer.android.com/reference/android/media/AudioFormat#channelMask
The fix is to apply the channel mapping after decoding if needed.
Also add e2e tests with audio dumps for the extension renderer,
including a new 5.1 channel test file.

`mediaCrypto` is initialized before `codec` in
`maybeInitCodecOrBypass`. Before this change, it was possible for
`maybeInitCodecOrBypass` to complete with `mediaCrypto != null` and
`codec == null`, in particular if it was run as part of clearing the
player surface (since in that case, no video codec is initialized).
This inconsistent state then causes issues during a later invocation of
`maybeInitCodecOrBypass`, when `mediaCrypto` is still non-null, and
`mediaCryptoRequiresSecureDecoder = true`, but the
content has been changed to unencrypted with no associated DRM session.
This results in a playback error, because a secure decoder is
initialized but there's no DRM session available to work with it.
This change ensures that when `maybeInitCodecOrBypass` completes,
either both `mediaCrypto != null` and `codec != null` (i.e. codec
initialization was completed) or `mediaCrypto == null` and
`codec == null` (i.e. codec initialization was not completed). We also
ensure that when nulling out `mediaCrypto` we also set
`maybeInitCodecOrBypass = false`. A later change should be able to
demote `maybeInitCodecOrBypass` from a field to a local in order to
remove any risk of that part of state becoming out of sync. This
resolves the issue, because during the second invocation of
`maybeInitCodecOrBypass` an insecure decoder is now (correctly)
initialized and the unencrypted content is successfully played.

This change fixes a bug with seeking forward in MIDI. When seeking forward,
the progressive media period attempts to seek within the sample queue, if a
key-frame exists before the seeking position. With MIDI, however, we can
only skip Note-On and Note-Off samples and all other samples must be sent
to the MIDI decoder.
When seeking outside the sample queue, the MidiExtractor already
instructs the player to start from the beginning of the MIDI input. With
this change, only the first output sample is a key-frame, thus the
progressive media period can no longer seek within the sample queue and
is forced to seek from the MIDI input start always.

The live offset override is used to replace the media-defined
live offset after user seeks to ensure the live adjustment adjusts
to the new user-provided live offset and doesn't go back to the
original one.
However, the code currently clips the override to the min/max
live offsets defined in LiveConfiguration. This is useful to
clip the default value (in case of inconsistent values in the media),
but the clipping shouldn't be applied to user overrides as
the player will then adjust the position back to the min/max
and doesn't stay at the desired user position.

When transmuxing, the `EncodedSampleExporter` maintains a queue of input
buffers that get filled with encoded data by the asset loader. The number of
buffers was limited to avoid using more and more memory if producer (asset
loader) gets far ahead of the consumer (exporter).
Previously this limit was fixed at 10 buffers, but increasing the number of
buffers can make some transmux operations much faster. Allow allocating between
a min and max number of buffers, and also set a target allocation size beyond
which new buffers can't be allocated. This allows audio formats which require
many small buffers to be processed more quickly, while preventing allocating
too much memory for hypothetical very high bitrate formats.
'Remove video' edits on local videos in particular get much faster, because
audio buffers are very short and there are lots of them. With a sample 10
minute video, a 'remove video' edit took 2 seconds (36 seconds before this
change). With a sample 1 minute removing video took 0.25 seconds after this
change (2.5 seconds before).
The speed improvement is smaller for other types of edits that retain the video
track. Transmuxing a 10 minute video retaining the video track took 26 seconds
(40 seconds before).

In some contexts (e.g. BottomSheetDialogFrament), Material Design
themes will override the default of singleLine=false to true. This
causes layout problems because the forward/rewind buttons are no
longer visible with singleLine=true.
This problem can be avoided by explicitly requesting the default
value of false in our layout files.

This helps to play ads where the file extension is not sufficient
to deduce the correct source in DefaultMediaSourceFactory.
PiperOrigin-RevId: 582340114
Currently, ads are only defined by a single URL, which makes it
impossible to define additional fields needed to play ads correctly.
This can be fixed by using a full MediaItem in AdPlaybackState,
replacing the previous Uri field.

MIME types are case-insensitive, but none of the many existing
comparisons across our code base take this into account. The
code can be made more robust by normalizing all MIME types at the
moment they are first set into a class/builder and adding toLowerCase
as part of the normalization.
Most concretely, this fixes an issue with playing HLS streams via
the IMA SDK where the stream MIME type is indicated with all lower
case "application/x-mpegurl", which failed the MIME type comparison
in DefaultMediaSourceFactory.

This was intended to avoid bringing in a transitive dependency on the

DefaultTrackSelector now has all logic necessary for selecting an

If isPrioritizeImageOverVideoEnabled is set to true, image track will
try to be selected first and a video track will only be selected if no
image track is available. If isPrioritizeImageOverVideoEnabled is set
to false, image track will be selected only if video track wasn't
selected.

This has been documented to work since this class was created, but until
now we were always trying to resolve using the current application's
`Resources.getIdentifier` method. This commit changes to resolve to the
other app's `Resources` object if the package name doesn't match the
current package.
This will only work if the current app has package-visibility to the
destination package: http://g.co/dev/packagevisibility
This is hard to test because to do so robustly requires being able to
guaranteed that another test APK will be installed with a known raw
resource inside it.

Some devices supporting Performance Points for decoder coverage are missing coverage over the CDD requirements for H264. For these cases ExoPlayer should fall back to legacy resolution and frame rate support checks. If there is an H264 stream evaluated as a `PerformancePointCoverageResult` of `COVERAGE_RESULT_NO`, then ExoPlayer checks for coverage of the [720p CDD requirement](https://source.android.com/docs/compatibility/10/android-10-cdd#5_3_4_h_264).
