3612 /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
3613 * giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
3614 * two chroma(U and V) values. Each macropixel has two luminance values, one for
3615 * each single pixel it contains, and one U and one V value shared between both
3616 * pixels.
3617 *
3618 * The data is loaded into an A8L8 texture. With YUY2, the luminance component
3619 * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
3620 * take the format into account when generating the read swizzles
3621 *
3622 * Reading the Y value is straightforward - just sample the texture. The hardware
3623 * takes care of filtering in the horizontal and vertical direction.
3624 *
3625 * Reading the U and V values is harder. We have to avoid filtering horizontally,
3626 * because that would mix the U and V values of one pixel or two adjacent pixels.
3627 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
3628 * regardless of the filtering setting. Vertical filtering works automatically
3629 * though - the U and V values of two rows are mixed nicely.
3630 *
3631 * Appart of avoiding filtering issues, the code has to know which value it just
3632 * read, and where it can find the other one. To determine this, it checks if
3633 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
3634 *
3635 * Handling horizontal filtering of U and V values requires reading a 2nd pair
3636 * of pixels, extracting U and V and mixing them. This is not implemented yet.
3637 *
3638 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
3639 * with width / 2. This way one read gives all 3 values, finding U and V is easy
3640 * in an unfiltered situation. Finding the luminance on the other hand requires
3641 * finding out if it is an odd or even pixel. The real drawback of this approach
3642 * is filtering. This would have to be emulated completely in the shader, reading
3643 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
3644 * vertically. Beyond that it would require adjustments to the texture handling
3645 * code to deal with the width scaling
