Some Player implementations have no playlist capability but can still
set a MediaItem for playback. Examples are a MediaController connected
to a legacy MediaSession, ExoPlayer up to 2.12 or MediaPlayer.
To indicate this capability, we need an allowed command in addition
to COMMAND_CHANGE_MEDIA_ITEMS that just allows to set a single item
that replaces everything that is currently played.

With HLS chunkless preparation, audio formats may have no value

This provides an (unstable) API for apps to broadcast session extras
Bundle to all connected controllers and set the extras in the legacy
session.
Similar to the custom layout, the extras Bundle is not part of the
Media3 session state. This means that when a Media3 controller
connects to the session after the broadcast, the extras needs to be
sent to that controller in `MediaSession.Callback.onPostConnect(MediaSession session, ControllerInfo controller)`.

This value only existed to allow setting media URLs from external sources

The MediaItemFiller is not flexible enough for most realworld usages
because:
- it doesn't allow asynchronous resolution of MediaItems (e.g. to
look up URIs from a database)
- it doesn't allow to batch updates for multiple items or do more
advanced customizations (e.g. expanding a mediaId representing
a playlist to multiple items).
Both issues can be solved by passing in a list of items and
returning a ListenableFuture. The callback itself can also move
into MediaSession.Callback for consistency with the other
callbacks.

The MockPlayer currently:
- uses separate fields for single mediaItem vs multiple mediaItems
- replaces all items on addMediaItem operations
- does nothing on remove/move operations.

(for example only removing items from a playlist that have

ExoPlayer applies a large time offset to buffers so that, if the input has negative timestamps, generally buffers seen by the decoders should have positive timestamps. Modify how the offset is handled in `Transformer` so that decoders and encoders generally see positive timestamps, by leaving the offset on samples when reading them in the base renderer (remove the code that removed the offset), and then removing the offset when muxing. Also update the frame processor chain and slow motion flattening code to retain the existing behavior after this change (these both need original media presentation timestamps)
Tested via existing end-to-end tests and manually verified that the overlay frame processor shows the expected original media timestamps.
Aside: we don't need the same logic as ExoPlayer to track stream offsets across the decoder yet, because we don't try to handle stream changes during playback in single asset editing. (There is an edge case of multi-period DASH that may not work but I doubt anyone will use that as input to `Transformer` before we change the code to handle multi-asset properly.) In future we should try to refactor interaction with the decoder to use the same code for Transformer and ExoPlayer.

Unconditionally sleep for offload, if the audio buffer is full.
Previously ExoPlayer would not sleep if the expected wake-up was
in 2s. This was to prevent underrun if the wake-up was delayed.
Experiments have shown that the wakup audio buffer is far more
than 2s (around 1min). Additionally,
the metric was incorrect because it measured both,
AudioTrack + DSP.
Finally, this metric was erroneous after a gapless transition,
when the head position would reset to 0 and thus the computed
delay until next wakeup was too large.

Decode-only video frames (needed when the frame at / first frame after the

The clipping start offset needs to be removed from the frame timestamps

There are no changes needed for this in the audio pipeline, as it doesn't
use the input timestamps -- it uses its own timestamps derived from the

Representing HTTP headers in a `java.util.Map` is error-prone, because
the names (keys) need to be case-insensitive (per
[RFC 2616 section 4.2](https://datatracker.ietf.org/doc/html/rfc2616#section-4.2))
but this is fundamentally technically incompatible with the `Map`
interface (e.g. with headers `{"key": ["val_1", "val_2"]}` then
`get("key")` and `get("KeY")` both return the same list, but `size()`
returns `1`). It also breaks as soon as you copy the `Map` into a
non-case-insensitive (i.e. normal) `Map` implementation, e.g. Guava's
`ImmutableMap`. It's risky that a line as 'innocent' as
`ImmutableMap.copyOf(headers)` could break things so badly.
For now it's enough to keep this field unstable (it's currently the only
reference to HTTP headers in the stable API). We can consider
stabilising an improved HTTP header representation in future.

AudioTrack.setOffloadEndOfStream should be called after a track
has been buffered. Additionally, the AudioTrack must be playing.
It has been observed that for very short media (<1s), the AudioTrack
might not have started immediately after the read that buffered
the audio.
In such a situation, calling AudioTrack.setOffloadEndOfStream throws
and playback fails.
Avoid this failure by checking that the AudioTrack is playing before
calling setOffloadEndOfStream.
This means that very short gapless media will not be gapless, this was
deemed acceptable given that such very short media should be very rare
in offload.

Relates to https://github.com/square/okhttp/issues/3146. This was from https://github.com/androidx/media/pull/71.
There is a draft PR https://github.com/square/okhttp/pull/7185/files which documents OkHttp's ideal handling of cancellation including interrupts.
But a few key points
1) This is a target state, and OkHttp does not currently handle interrupts correctly. In the past this has been identified, and the advice is to avoid interrupts on Http threads, see discussion on https://github.com/square/okhttp/issues/1902. Also an attempt at a fix here https://github.com/square/okhttp/pull/7023 which wasn't in a form to land.
2) Even with this fixed, it is likely to never be optimal, because of OkHttp sharing a socket connection for multiple inflight requests.
From https://github.com/square/okhttp/pull/7185
```
Thread.interrupt() is Clumsy
----------------------------
`Thread.interrupt()` is Java's built-in mechanism to cancel an in-flight `Thread`, regardless of
what work it's currently performing.
We recommend against using `Thread.interrupt()` with OkHttp because it may disrupt shared resources
including HTTP/2 connections and cache files. In particular, calling `Thread.interrupt()` may cause
unrelated threads' call to fail with an `IOException`.
```

This fixes some small niggles:
1. `inferContentType(String)` is documented to take a path, but in the
tests we're passing full URIs.
2. A `String` parameter is usually a path, but also a MIME type or an
extension. In the new methods, the meaning of a `String` parameter
is always clear from the name of the method.
3. `inferContentType(String)` is always passed an extension in
'production' code (which has to be manually prefixed with a dot).
4. `inferContentType(Uri, @Nullable String)` always ignores the Uri if
the String is non-null. IMO this logic is clearer to a reader if it's
just in-lined at the call-site.
These methods are used from the demo apps, so will be part of the stable

Some devices under report their resolution support, like 2144 for 2160 in
H265, 1072 for 1080 in H264. This CL only takes care of these two cases,
- reporting 1920x1080 is supported when the device reports 1920x1072, and
- reporting 3840x2160 is supported when the device reports 3840x2144

When downlading an adaptive asset, if an ExoPlaybackException happens

This is safer because it will prevent any future problems with
creating a new FrameProcessorChain before the previous one has
completed its async release.
From [eglDestroyContext documentation](https://www.khronos.org/registry/EGL/sdk/docs/man/html/eglDestroyContext.xhtml):
"If the EGL rendering context is not current to any thread,
eglDestroyContext destroys it immediately."
The context isn't current to any thread here because GlUtil calls
eglMakeCurrent with EGL_NO_CONTEXT before calling eglDestroyContext.
So everthing should be released once the FrameProcessorChain's
release task terminates.

The stream with the mp3 track is added because

The MIME type was set to H265 to force transcoding. Now that we have an encoder

We add an entire class like we do for parsing other codec initialization formats; it's currently not doing any parsing though (... initialization data is really simple for AV1 though: just the entire contents of the box).

Since the output textures and surfaces are managed by the

This change adds the ability to update the error code of the PlaybackStateCompat in
cases we need this for backwards compatibility. It is applied in the least
intrusive way because normally, return values of a service method should not change
the state of the `PlaybackStateCompat`, just because it has nothing to do with the
playback state but rather with the state of the `MediaLibrarySession`.
For this reason only the error code `RESULT_ERROR_SESSION_AUTHENTICATION_EXPIRED`
is taken into account while all other error codes are not mapped to the
`PlaybackStateCompat'.

On some devices, decoding gets stuck when the number of frames pending at the
`SurfaceTexture` is too high. We added a workaround that only allows one frame
to be pending at a time. That fixed the issue, however, based on on-device
testing it seems that it's safe to queue more than one frame.
Add a method that returns a safe estimate of the number of frames that can be
pending at a time, and use this to limit the number of frames that can be
released from the decoder but not processed by the frame processor chain.
PiperOrigin-RevId: 437057075

When the start position of a MediaPeriodInfo is equal or higher than the duration,
we set the start position to `duration - 1` to end on the last frame. With server
side inserted ad streams, this has the effect that we actually need to seek back to
the last content frame after a post-roll.
This is desirable when actually ending on that frame but produces a BUFFERING event
when transitioning from an SSAI stream with a post-roll to the next media item in
the playlist. This change sets the start position to the duration when we are
clipping the last content period of an SSAI stream that is played in a playlist.

This makes the reading period advance early as expected at the end of an ad

prevented advancing the period until metadata arrived after the start position of

Because transitioning to the next period is a virtual transition and the

The MockPlayer has a single CountDownLatch field and multiple boolean
flags that track if a player method was called. Upon calling the methods
the latch count. Tests set the latch count to match exactly with the
number of expected player interactions then block the test thread until
the latch reaches zero and assert the respective method flags are true.
This is subject to false positives. If the underneath implementation
changes and call more player method, then the test thread will unblock
as soon as a certain number of interactions is performed, which may be
less than what the test expected originally. However, the test may stil
pass if the player thread had enough time to update the expected method
flag.
This change removes the single CountDownLatch and the boolean flags and

addTrackSelectionForSingleRenderer takes a list of legacy overrides,
which are then set on the supplied parameters one at a time to run

possible to place such overrides directly into a single parameters.
For new style overrides, multiple overrides for the same track type
can be placed directly into a single parameters. Therefore we'll be
able to replace use of addTrackSelectionForSingleRenderer with use
of addTrackSelection, which is a much cleaner API. For this to work,
we need to make DownloadHelper apply multiple overrides in this case.

We use SSIM to measure the transcoding quality between. SSIM is a widely used
tool that compares the luma channel between two images, and generates a score
from 0 to 1 that indicates "how similar" the two images are.
In `SsimHelper`, we decode the two videos, extract matching frames and
calculates the mean SSIM (SSIM averaged all matching frames) for both videos.
Matching frames are referred to as "comparisonFrame" in the CL, which is
selected based on the frame number and a user-set comparison interval.
For instance, if the interval is 7, then every seventh frames are compared.
We use MediaCodec/MediaExtractor to decode the video, and use ImageReader to
extract the decoded frame.
The SSIM calculation logic is a inspired by and modified from the CTS
[MSSIMMatcher](https://cs.android.com/android/platform/superproject/+/master:cts/tests/tests/uirendering/src/android/uirendering/cts/bitmapcomparers/MSSIMComparer.java;l=1?q=mssimcom)

images).

We need to access internal state to work around resources not being released on
old API versions. Add a reference to the bug about this and suppress the lint

All (later customizable) GlFrameProcessors after the
ExternalCopyFrameProcessor receive their input from a normal OpenGL
texture not an external texture, so they won't need to worry about
the textureTransformMatrix.

There are two major blockers to this test:
- H265 muxing is not available for API<24, so setting video mimeType to H265
will fail on those devices.
- AMR audio encoding is buggy on some device and it's not a widely used format.
The solution: use a video that is encoded with AVC/MP3, to ensure transcoding
to AVC/AAC.

the MSG_RELEASE message is already in the internal player queue.
- The demo app was failing because the stop watch was stopped in
onTransformationError after being reset.
