VideoStreamContainer()

MayaFlux::Kakshya::VideoStreamContainer::VideoStreamContainer	(	uint32_t	width = 0,
		uint32_t	height = 0,
		Portal::Graphics::ImageFormat	format = Portal::Graphics::ImageFormat::RGBA8,
		double	frame_rate = 0.0
	)

Construct a VideoStreamContainer with specified parameters.

Parameters

width	Frame width in pixels.
height	Frame height in pixels.
format	Pixel format; determines channel count, bytes per pixel, the DataVariant element type, and whether the structure is VIDEO_COLOR or VIDEO_DEPTH.
frame_rate	Temporal rate in frames per second.
