3605 /* The YUY2 and UYVY formats contain two pixels packed into a 32 bit macropixel,
3606 * giving effectively 16 bit per pixel. The color consists of a luminance(Y) and
3607 * two chroma(U and V) values. Each macropixel has two luminance values, one for
3608 * each single pixel it contains, and one U and one V value shared between both
3609 * pixels.
3610 *
3611 * The data is loaded into an A8L8 texture. With YUY2, the luminance component
3612 * contains the luminance and alpha the chroma. With UYVY it is vice versa. Thus
3613 * take the format into account when generating the read swizzles
3614 *
3615 * Reading the Y value is straightforward - just sample the texture. The hardware
3616 * takes care of filtering in the horizontal and vertical direction.
3617 *
3618 * Reading the U and V values is harder. We have to avoid filtering horizontally,
3619 * because that would mix the U and V values of one pixel or two adjacent pixels.
3620 * Thus floor the texture coordinate and add 0.5 to get an unfiltered read,
3621 * regardless of the filtering setting. Vertical filtering works automatically
3622 * though - the U and V values of two rows are mixed nicely.
3623 *
3624 * Appart of avoiding filtering issues, the code has to know which value it just
3625 * read, and where it can find the other one. To determine this, it checks if
3626 * it sampled an even or odd pixel, and shifts the 2nd read accordingly.
3627 *
3628 * Handling horizontal filtering of U and V values requires reading a 2nd pair
3629 * of pixels, extracting U and V and mixing them. This is not implemented yet.
3630 *
3631 * An alternative implementation idea is to load the texture as A8R8G8B8 texture,
3632 * with width / 2. This way one read gives all 3 values, finding U and V is easy
3633 * in an unfiltered situation. Finding the luminance on the other hand requires
3634 * finding out if it is an odd or even pixel. The real drawback of this approach
3635 * is filtering. This would have to be emulated completely in the shader, reading
3636 * up two 2 packed pixels in up to 2 rows and interpolating both horizontally and
3637 * vertically. Beyond that it would require adjustments to the texture handling
3638 * code to deal with the width scaling
