calculate_output_region() [2/2]

Region MayaFlux::Kakshya::calculate_output_region	(	uint64_t	current_frame,
		uint64_t	frames_to_process,
		const std::shared_ptr< SignalSourceContainer > &	container
	)

Calculate output region for frame-based processing.

Parameters

current_frame	Current frame index.
frames_to_process	Number of frames to process.
container	Container providing layout information.

Returns

Region representing the output bounds for the specified frames.
