VideoContainerBuffer()

MayaFlux::Buffers::VideoContainerBuffer::VideoContainerBuffer	(	const std::shared_ptr< Kakshya::StreamContainer > &	container,
		Portal::Graphics::ImageFormat	format = Portal::Graphics::ImageFormat::RGBA8
	)

Construct a VideoContainerBuffer from a video container.

Extracts width, height, and pixel format from the container's structure and initialises the TextureBuffer base with matching dimensions. Creates a pending VideoStreamReader that is wired on initialize().

Parameters

container	Backing video StreamContainer (must carry VIDEO_COLOR data).
format	Pixel format (default RGBA8 matching container convention).
