Fallback is only disabled for robolectric and instrumentation tests.
For MH tests, fallback is not disabled, as it may be needed due to
the broad range of devices available.

TransformerTest sounds like a unit test for Transformer but these
tests test behaviour that involves multiple stages of the pipeline.

If the output sample MIME type is inferred from the input
but is not supported by the muxer, we fallback to transcoding
to a supported sample MIME type.
The audio and video renderers need to make sure not to select the PassthroughSamplePipeline for this case. Which sample MIME type
to choose is decided by the EncoderFactory.
PiperOrigin-RevId: 423272812
We may fall back to a different sample MIME type because
a) the sample MIME type inferred from the input is not supported
by the muxer or b) no encoders are available for the the requested
sample MIME type.

After implementing fallback, it won't always be possible to
differentiate between muxer and encoder as the cause of an output
format not being supported.

The app will be notified about fallback using a callback on
Transformer.Listener. Fallback may be applied separately for
the audio and video options, so an intermediate internal
FallbackListener is needed to accumulate and merge the track-specific
changes to the TransformationRequest.

Exceptions thrown by MediaMuxer are converted MuxerExceptions
and later to TransformationExceptions with ERROR_CODE_MUXING_FAILED.

* Move checking that the output format is supported by the muxer
from supportsFormat (which deals with the input format) to
ensureConfigured.
* Add maps for the supported MIME types so that the muxer can
return what MIME types it supports rather than just check a
MIME type.

This is better than silently dropping tracks as done previously. Later,
we will implement fallback to transcoding to a supported MIME type.

Transformer uses ExoPlayer for reading input. Apps using Transformer
do not need to know this. So, PlaybackExceptions are converted to
TransformationExceptions with the same message, cause and error code.
The corresponding IO error codes are copied from PlaybackException.

Buffers that are useful to pass to the sample/passthrough pipeline
should either contain data or the end of input flag. Otherwise, passing
these buffers along is unnecessary and may even cause the decoder to
allocate a new input buffer which is wasteful.

This mime type is technically for the Muxer, and determines
the container used. In the context of the transformer, this can
be thought of more as a container mime type, to avoid confusion
with the video mime type and audio mime type.
Deprecates setOutputMimeType().

If the number of samples changes, the sizes will help us to verify
whether they are just split differently or extra data was added.
