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.

Move `inputColorInfo` from `VideoFrameProcessor`'s `Factory.create` to `FrameInfo`,
input via `registerInputStream`.
Also, manually tested on exoplayer demo that setVideoEffects still works.
PiperOrigin-RevId: 591273545
Also adds an alternate way to configure the AudioGraph.
Apps should no longer need to ensure that inputs have the same sample
rate.

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.

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.

Composition and EditedMediaItemSequence don't allow empty lists in their main

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.

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.

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.

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.

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.

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.

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
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
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
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

We will need to build upon original composition
for pause and resume feature and will have to set modified sequences.
In the next CL, will add method to set sequences on builder and will
probably remove it from the constructor parameter (to avoid providing
two APIs for same thing).

ExoPlayer queues the EOS buffer to the decoder with offset/size/timestamp all
equal to zero, and a EOS flag.
69769c77b3 set TIME_END_OF_SOURCE on the EOS buffer from the extractor.
Queueing the EOS buffer to the decoder with TIME_END_OF_SOURCE causes some
decoders to output wrong timestamps in its output.
This CL replicates what ExoPlayer does in Transformer.

After this change, every queued bitmap is treated as an individual input stream
(like a new MediaItems).
This change merges the FrameDropTest and FrameDropPixelTest into one (while maintaining all the test cases)
- This is accomplished by generating bitmaps with timestamps on it in FrameDropTest and compare them with goldens (one may call this a pixel test, please lmk if you want this to be renamed)
- The most part of the change comes from DefaultVideoFrameProcessorVideoFrameRenderingTest. The overall working is
- We bypass the input manager
- The TestFrameGenerator generates frames based on timestamps. In this case, we generate frames with timestamps on it
- The generated frame is sent to texture output and in turn saved to bitmaps
- We then compare the generated bitmap with the goldens

This should make no functional difference because `SampleExporter` always
checks for H.265 and H.264 first. However, in case we ever change that code,
these are used in priority order so it's better to order them accordingly.
PiperOrigin-RevId: 550894935
When generating silence for AudioProcessingPipeline, audio never
queued EOS downstream.
Linked to this, when silence followed an item with audio, the silence
was added to SilentAudioGenerator before the mediaItem reconfiguration
occurred. If the silence had effects, the APP would be flushed after
silence queued EOS, resetting APP.isEnded back to false, so AudioGraph
never ended.
Regression tests reproduce failure without fix, but pass with it.

AudioMixingUtil#mix handles input & output in float or Int16 PCM. Given
Float and Int16 use different sample ratnes, this util handles
conversion between the two, based on the encoding being mixed to.
Migrate AudioMixer to use the util, removing AudioMixingAlgorithm
interface and implementation. ChannelMixingAudioProcessor will be
migrated after additional performance checks.

On a MediaItem change, the input Format (and Effects to apply) may be
different. Therefore the AudioProcessingPipeline must be reconfigured
to determine what processing is active, and what the AudioFormat of the
data output is. In the event that it is different, additional
AudioProcessor instances must be used to ensure the encoder will still
be able to accept the audio buffers.

MP4 edit lists sometimes ask to start playback between two samples.
If this happens, we currently change the timestamp of the first
sample to zero to trim it (e.g. to display the first frame for a
slightly shorter period of time). However, we can't do this to audio
samples are they have an inherent duration and trimming them this
way is not possible.
