| * 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. |
| * |
| * Appart 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 |
