recommend disabling B-frames on API 27, but some devices output B-frames anyway
when H.264/AVC High profile is selected. Add a workaround to force these
devices not to use high profile, to prevent B-frames being output.
`MediaMuxer` likely handles B-frames on these specific devices, but this change
allows the migration to default to in-app muxing to take place without
introducing errors, and it's a temporary workaround until B-frames are properly
supported in the in-app muxer.

This device doesn't seem to be capable of simultaneous encode/decode at this
resolution. We don't have a good way to check the capability (we are already
checking separate decode/encode capability) so just skip this test to save time
triaging its failures.

Although not public, documenting what happens in each state allows for
better code understanding at a glance.
As part of this, refactored the #getProgress method to highlight that
the other options are "non standard".

Moves setting bitmapFactory options from BitmapLoader to DatasourceBitmapLoader
BitmapLoader is a general interface for bitmap loading that could use loading implementations other that BitmapFactory, with the rise of Glide being a loader of choice. It's best to correct this interface so that it remains generic
We can't deprecate easily because the other loadBitmap method in that case has a default implementation that relies on the first one, so the change is still breaking. BitmapLoader is public api in common, but it's @UnstableAPI and hasn't been around for very long (be38670391 added it), so it seems this is the best way forward.

This file is CBR encoded with LAME, so it has an `Info` header (the CBR
equivalent to `Xing`).
A follow-up change will use this file in `Mp3ExtractorTest`.
Issue: androidx/media#878
PiperOrigin-RevId: 595938327
Mp4Muxer does not support out of order B-frames. Currently it
silently writes out of order B-frames, producing an invalid file (with
negative sample durations).
Although `Mp4Extractor` is somehow able to process this invalid file and
`Exoplayer` is able to play it but that is unexpected.
The `sample.mp4` test file contains B frames. Other test files does not
contain `H264 video + AAC audio` format hence created a new test file by
running `sample.mp4` via `Transformer` after applying some effects.
PiperOrigin-RevId: 594016144
Instead, for input videos, use the colorInfo provided by the extractor. Similarly, for input images, use sRGB, the only color currently in use.
Textures do still need the input ColorInfo provided though.
PiperOrigin-RevId: 592875967
Replace the event for notifying fallback to cover codec initialization in
general (but keeping the list of errors).
Add a flag to control whether to try non-primary codecs, with the same
documentation as the similar flag in ExoPlayer's renderer.
Make the class final as it shouldn't be necessary to subclass it.
PiperOrigin-RevId: 592869868
Checking the output format's mime type may skip tests more often than we'd like,
because we may desire using a lower-spec output mimetype than what's passed in, if
based on the input's HDR mimetype value.
Therefore, update this output format to null, for tone-mapping tests
PiperOrigin-RevId: 592855713
Move `inputColorInfo` from `VideoFrameProcessor`'s `Factory.create` to `FrameInfo`,
input via `registerInputStream`.
Also, manually tested on exoplayer demo that setVideoEffects still works.

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.
PiperOrigin-RevId: 590569772
Also adds an alternate way to configure the AudioGraph.
Apps should no longer need to ensure that inputs have the same sample
rate.

Added a new ABANDONED option so one can tell the difference between when the optimization has been requested but not applied vs not requested at all. also changed the ordering do better represent the hierarchy of failure modes

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.

* @Before and @After usage. [1].
* static fields before non-static. [2].
@Before method should typically be paired with an @After method,
focused on ensuring that the component is released regardless of what
the test does.
In tests, inlining final class variables is preferrable [1]. In general
things like the file path should be part of the test (the @Rule means
we don't need before/after) if only used once.
Statically importing values and using them directly is preferable to
having a variable declared as non-final that's effectively final,
because from a readability perspective someone can see (the caps) that
the value is final static and immutable, so doesn't have to check if
it's changed/reassigned.

The issue that motivated adding this (frames unexpectedly being dropped by the
decoder) has been addressed, so we can turn off the logging to reduce
unnecessary allocations during transformation. We can easily turn on debug
logging in future as needed by setting `DebugTraceUtil.DEBUG = true`.
Also avoid allocations for string building at logging call sites by passing a
format string for extra info. Formatting the string now only happens when
debugging is turned on.
Tested manually by running transformations in the new state (DEBUG = false) and
with debugging turned on.
PiperOrigin-RevId: 585666349
The decoder and encoder won't accept high values for frame rate, so avoid
setting the key when configuring the decoder, and set a default value for the
encoder (where the key is required).
Also skip SSIM calculation for 4k, where the device lacks concurrent decoding
support.

Using `Integer.MAX_VALUE` risks causing arithmetic overflow in the codec
implementation.

These usages have no need for the double ended input functionality. All
other usages across media3 are ConcurrentLinkedQueue.

Composition and EditedMediaItemSequence don't allow empty lists in their main
constructors, so shouldn't the vararg API. This is more inline with Effective
Java item 53.

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).

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.

Skip wearable devices, which don't have the same CDD requirements on codecs from Android 5 (API 21).
Limit an existing skipping case to pre API 33 devices, so that we can catch failures on Android 13 (API 33) onwards, and add OnePlus 9 Pro which also times out calculating SSIM. Remove TODOs for removing test/SSIM skipping now they are restricted to API version.
PiperOrigin-RevId: 581985554
This device over-reports encoding capabilities, so skip the test.
This is a Pixel device that was upgraded to Android 12 (API 31/32) so the issue should only affect devices that didn't take OTAs.

The dump file diff as part of this change is because using AudioGraph
means the 2nd item is automatically edited to match the AudioFormat of
the 1st item {44.1KHz mono}, rather than {48KHz stereo}.
Manually verified that for the 2nd item, data output:
* Before: 66936 bytes (16734 frames) output = 348_625us of audio.
* After: 30750 bytes (15375 frames) output = 348_639us of audio.
The small final buffer is caused by SonicAudioProcessor outputting all
pending data when EOS queued, and is WAI.

1. Add resume flow.
2. Change demo app code to resume export.
3. Changes in test infra to trigger resume.
4. E2E Test cases

When transmuxing, we usually only need to offset the timestamp by the position of a mediaItem in a sequence.
Trim optimization introduces another type of offset: for the transmux of the second part of the video we need to offset the timestamps by the total duration already trancoded by transformer.

Move remote 8K file to local and trim to 320ms.

MediaCodecRenderer has already been updated to not rely on the
input stream to mark its samples as decode-only and instead use
a simple time-based comparison to achieve the same effect.
This change makes the same update for all other renderers that
either use the flag directly or forward to a "decoder" instance.
PiperOrigin-RevId: 568232212
If getProgress is blocking whilst the internal thread calls endInternal
(for error or success), the condition is never opened. Related to this,
onCompleted and onError are therefore never surfaced to the app.
progressState is accessed from application and internal threads, so
should be marked volatile to prevent a thread caching the value.
PiperOrigin-RevId: 565720184
When we switch from MUXER_MODE_MUX_PARTIAL_VIDEO to MUXER_MODE_APPEND_VIDEO
`muxedPartialVideo` will already be `true` so `endTrack` method will pass
through this `if(muxedPartialVideo)` check which is incorrect.

The logic that handles components' boundaries are grouped together in private
methods, like handling VideoCompositor's output textures.

For pause and resume feature we need to use same `MuxerWrapper`
for `remuxing processed video` and then to `process remaining video`.
In order to use same `MuxerWrapper` across `different Exports`
we need to preserve its state.
PiperOrigin-RevId: 564728396
Modifying dumping to not required "released" to be called.
Track index is an arbitrary value based on the order of addTrack calls.
Samples are dumped by track (rather than as soon as they are written),
so it's preferable to use a value that provides more context.
By using the track type as a key, dump files will be more deterministic
and will have more similarities when branched.
PiperOrigin-RevId: 563700982
That said, only SDR is supported for now, so this will always throw if
HDR is input. This will also throw if different ColorInfo values are input
because color SDR mixing (ex. between sRGB and BT709) is not yet supported.
PiperOrigin-RevId: 563457729
For pause and resume feature we will need to build `ExportResult`
from multiple internal Exports. Keeping the `ExportResultBuider` in
`Transformer` class will allow using same builder across different
internal exports.
PiperOrigin-RevId: 563392443
When checking the color transfer, there is no reason that the file should have
exactly two tracks, and this assertion means that this method can't be used
as-is for checking video-only files, for example.
PiperOrigin-RevId: 562813111
Overlays may be overlaid over:
* In VideoFrameProcessor, videos or images (or texture input).
* In Compositor, other videos.
In Compositor, Overlays may consist of video, so it could be confusing
for videoFrameAnchor to contrast with overlayAnchor.
Also, rename overlayAnchor to overlayFrameAnchor, since it's modifying
the anchor in the overlay's frame, so this name seems slightly more precise.
PiperOrigin-RevId: 562004292
Implement VideoCompositor support of:
* Different input and output sizes
* CompositorSettings, to customize output size based on input texture sizes
* OverlaySettings, to place an input frame in an arbitrary position on
the output frame.
Also, refactor Overlay's matrix logic to make it more reusable between
Compositor and Overlays
PiperOrigin-RevId: 561931854
For pause and resume feature we will remux the previously processed
video in the first export and then in the second export we will resume
processing remaining video. For the second export we will have to
set initial timestamp offset so that video samples from the second
export are in continuation to the previously muxed samples.
PiperOrigin-RevId: 561689651
For pause and resume we need to perform multiple intermediate exports.
So moved start() logic into a separate so that it can be reused from
different places with different Compositions and MuxerWrapper.
PiperOrigin-RevId: 561675472
Switch to SparseArray<List> rather than a Map<Integer, List>.
Track indices now determine sample list dumping, reducing flakiness.
PiperOrigin-RevId: 561658586
For pause/resume feature, same MuxerWrapper needs to be
used across intermediate exports. So pass the MuxerWrapper
from Transformer.java
More specifically, when resume() is called
1. Create a MuxerWrapper and remux the previous
video samples (Export 1).
2. User the same MuxerWrapper and start processing
remaining video samples (Export 2).

More specifically, this CL
- Defines a VideoGraph interface
- Adds a factory method, to hide the constructors
- Separate out an initialize method that does the real work (following that constructor should not do real work)
- The VideoGraph takes in a list of composition effects. For now, we only use the `Presentation`, if there is one in the list. This means we can take any number of Presentations now, but only the first one will be used.
- Moves the VideoFrameProcessingWrapper to its own file
PiperOrigin-RevId: 561059653
For pause and resume feature we need to find the timestamp of
the last sync sample in an MP4 file. The Mp4ExtractorWrapper
provides an easy to use API on top of Mp4Extractor.
