379
         *   [0,255] or the 10/12bpp equivalents thereof) to an integer version
380
         *   of RGB in psuedo-restricted 15+sign bits. That means that the float
381
         *   range [0.0,1.0] is in [0,28762], and the remainder of the int16_t
382
         *   range is used for overflow/underflow outside the representable
383
         *   range of this RGB type. rgb2yuv is the exact opposite.
384
         * - gamma correction is done using a LUT since that appears to work
385
         *   fairly fast.
386
         * - If the input is chroma-subsampled (420/422), the yuv2rgb conversion
387
         *   (or rgb2yuv conversion) uses nearest-neighbour sampling to read
388
         *   read chroma pixels at luma resolution. If you want some more fancy
389
         *   filter, you can use swscale to convert to yuv444p.
390
         * - all coefficients are 14bit (so in the [-2.0,2.0] range).
