process_to_live_container() [1/2]

std::shared_ptr< Kakshya::TextureCollection > MayaFlux::Yantra::Vision::VisionWorkflow::process_to_live_container	(	const std::shared_ptr< VisionMatrix > &	matrix,
		const std::shared_ptr< Kakshya::VideoStreamContainer > &	source,

		const std::optional< LiveConfig > &	live = {}
	)

process_to_live_container() with a matrix the caller made and configured.

Returns

The collection, or null when matrix is null or as process_to_live_container() fails.
