Converts monochrome (luminance) to UYVY The jit.luma2uyvy object converts a 1-plane monochrome (lumninance) matrix to a 4-plane char UYVY (signed chroma blue, luminance left, signed chroma red, luminance right) matrix. Cycling '74 Jitter Jitter Colorspace in TEXT_HERE TEXT_HERE out TEXT_HERE dumpout TEXT_HERE char Alpha channel is lost and the horizontal dimension is halved to account for this half chroma, macro pixel out format. The UYVY format is typically useful for efficiently transfering chroma reduced codecs to the GPU without the expense of colorspace conversion, or bandwidth requirements of a full chroma format.
