void NV21_T_RGB(unsigned int width , unsigned int height , unsigned char *yuyv , unsigned char *rgb){const int nv_start = width * height ; u32 i, j, index = 0, rgb_index = 0; u8 y, u, v; int r, g, b, nv_index = 0; for(i = 0; i < height ; i++) { for(j = 0; j < width; j ++){ //nv_index = (rgb_index / 2 - width / 2 * ((i + 1) / 2)) * 2; nv_index = i / 2 * width + j - j % 2; y = yuyv[rgb_index]; u = yuyv[nv_start + nv_index ]; v = yuyv[nv_start + nv_index + 1]; r = y + (140 * (v-128))/100; //r g = y - (34 * (u-128))/100 - (71 * (v-128))/100; //g b = y + (177 * (u-128))/100; //b if(r > 255) r = 255; if(g > 255) g = 255; if(b > 255) b = 255; if(r < 0) r = 0; if(g < 0) g = 0; if(b < 0) b = 0; index = rgb_index % width + (height - i - 1) * width; rgb[index * 3+0] = b; rgb[index * 3+1] = g; rgb[index * 3+2] = r; rgb_index++; } } return 0;} 以上是NV21转rgb,那么NV12转rgb怎么写呢？很简单，将u、v两句代码互换就可以了。 转载地址：http://lelum.baihongyu.com/
