YUV 转RGB代码如下

 public static int[] yuvToRGBA (byte[] data, int width, int height){
        int frameSize = width * height;
        int[] rgba = new int[frameSize];
        for (int i = 0; i < height; i++) {
            for (int j = 0; j < width; j++) {
                int y = (0xff & ((int) data[i * width + j]));
                int u = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 0]));
                int v = (0xff & ((int) data[frameSize + (i >> 1) * width + (j & ~1) + 1]));
                y = y < 16 ? 16 : y;
                int r = Math.round(1.164f * (y - 16) + 1.596f * (v - 128));
                int g = Math.round(1.164f * (y - 16) - 0.813f * (v - 128) - 0.391f * (u - 128));
                int b = Math.round(1.164f * (y - 16) + 2.018f * (u - 128));
                r = r < 0 ? 0 : (r > 255 ? 255 : r);
                g = g < 0 ? 0 : (g > 255 ? 255 : g);
                b = b < 0 ? 0 : (b > 255 ? 255 : b);
                rgba[i * width + j] = 0xff000000 + (b << 16) + (g << 8) + r;
            }
        }
        return rgba;

    }

yuv 数据转 bitmap

public static Bitmap yuvToBitmap(byte[] data, int width, int height) {

        Bitmap bmp = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        bmp.setPixels(yuvToRGBA(data,width,height), 0 , width, 0, 0, width, height);
        return bmp;
    }
