Each macropixel has two * luminance values, one for each single pixel it contains, and one U and * one V value shared between both pixels. * * The data is loaded into an A8L8 texture. With YUY2, the luminance * component contains the luminance and alpha the chroma. With UYVY it is * vice versa. Thus take the format into account when generating the read * swizzles * * Reading the Y value is straightforward - just sample the texture. The * hardware takes care of filtering in the horizontal and vertical * direction. * * Reading the U and V values is harder. We have to avoid filtering * horizontally, because that would mix the U and V values of one pixel or * two adjacent pixels. Thus floor the texture coordinate and add 0.5 to * get an unfiltered read, regardless of the filtering setting. Vertical * filtering works automatically though - the U and V values of two rows * are mixed nicely. * * Apart of avoiding filtering issues, the code has to know which value it * just read, and where it can find the other one. To determine this, it * checks if it sampled an even or odd pixel, and shifts the 2nd read * accordingly. * * Handling horizontal filtering of U and V values requires reading a 2nd * pair of pixels, extracting U and V and mixing them. This is not * implemented yet. * * An alternative implementation idea is to load the texture as A8R8G8B8 * texture, with width / 2. This way one read gives all 3 values, finding * U and V is easy in an unfiltered situation. Finding the luminance on * the other hand requires finding out if it is an odd or even pixel. The * real drawback of this approach is filtering. This would have to be * emulated completely in the shader, reading up two 2 packed pixels in up * to 2 rows and interpolating both horizontally and vertically. Beyond * that it would require adjustments to the texture handling code to deal * with the width scaling. */ if (complex_fixup == COMPLEX_FIXUP_UYVY) { chroma = 'x'; luminance = gl_info->supported[WINED3D_GL_LEGACY_CONTEXT] ?
