Function Documentation

void yuv2rgb_init	(	int	bpp,
		int	mode
	)

yuv2rgb_fun yuv2rgb_init_mmxext	(	int	bpp,
		int	mode
	)

This returns a yuv to rgba converter, using mmxext if MMX was compiled in.

Parameters:

	mode	must be MODE_RGB
	bpp	must be 32

Returns:

function pointer or NULL if converter could not be found.

Definition at line 348 of file yuv2rgb.cpp.

yuv2rgb_fun yuv2rgb_init_mmx	(	int	bpp,
		int	mode
	)

This returns a yuv to rgba converter, using mmx if MMX was compiled in.

Parameters:

	mode	must be MODE_RGB
	bpp	must be 32

Returns:

function pointer or NULL if converter could not be found.

		int	height,
		int	srcwidth
	)

Convert planar RGB to YUV420.

Despite the name, this actually converts to i420

conv_2vuy_i420_fun get_2vuy_i420_conv

(

void

)

Returns 2VUY to I420 conversion function.

See http://developer.apple.com/quicktime/icefloe/dispatch019.html for a complete description of 2VUY and fourcc.org for YUV 4:2:0.

2vuy is a like a 8-bit per component YUV 4:2:2, but it's actually a Y'Cb'Cr sampling. 2vuy is packed with bytes [Cb, Y, Cr, Y] representing two pixels.

Returns:

A pointer to a 2VUY to I420 conversion function, which uses Altivec when supported.
