6162 * two chroma(U and V) values. Each macropixel has two luminance values, one for
6163 * each single pixel it contains, and one U and one V value shared between both
6166 * The data is loaded into an A8L8 texture. With YUY2, the luminance component
6167 * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
6168 * take the format into account when generating the read swizzles
6170 * Reading the Y value is straightforward - just sample the texture. The hardware
6171 * takes care of filtering in the horizontal and vertical direction.
6173 * Reading the U and V values is harder. We have to avoid filtering horizontally,
6174 * because that would mix the U and V values of one pixel or two adjacent pixels.
6175 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
6176 * regardless of the filtering setting. Vertical filtering works automatically
6177 * though - the U and V values of two rows are mixed nicely.
6179 * Appart of avoiding filtering issues, the code has to know which value it just
6180 * read, and where it can find the other one. To determine this, it checks if
6181 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
6183 * Handling horizontal filtering of U and V values requires reading a 2nd pair
6184 * of pixels, extracting U and V and mixing them. This is not implemented yet.
6186 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
6187 * with width / 2. This way one read gives all 3 values, finding U and V is easy
6188 * in an unfiltered situation. Finding the luminance on the other hand requires
6189 * finding out if it is an odd or even pixel. The real drawback of this approach
6190 * is filtering. This would have to be emulated completely in the shader, reading
6191 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
6192 * vertically. Beyond that it would require adjustments to the texture handling
6193 * code to deal with the width scaling
