YUV422转RGB

YUV422格式为YV16，YV16的存储方式是3 planer，即先存储所有的y，然后是所有的u，最后是所有的v。

public static int[] YV16ToRGB(byte[] src, int width, int height){int numOfPixel = width * height;int positionOfU = numOfPixel;int positionOfV = numOfPixel/2 + numOfPixel;int[] rgb = new int[numOfPixel*3];for(int i=0; i<height; i++){int startY = i*width;int step = i*width/2;int startU = positionOfU + step;int startV = positionOfV + step;for(int j = 0; j < width; j++){int Y = startY + j;int U = startU + j/2;int V = startV + j/2;int index = Y*3;rgb[index+R] = (int)((src[Y]&0xff) + 1.4075 * ((src[V]&0xff)-128));rgb[index+G] = (int)((src[Y]&0xff) - 0.3455 * ((src[U]&0xff)-128) - 0.7169*((src[V]&0xff)-128));rgb[index+B] = (int)((src[Y]&0xff) + 1.779 * ((src[U]&0xff)-128));}}return rgb;}
