Aspect ratio in width:height form (for example, '16:9', '9:16', '1:1', '4:5').
OptionalCancellationOptional signal for cancelling the request. The driver is responsible for honoring it: it
passes the signal to the provider's SDK or HTTP call, so an aborted request is torn down

classified as Cancelled (see BuildCancellationErrorInfo), which is never failed over.

Generation mode selecting how input references/video are used.
