IDirect3DSurface9的D3DFORMAT格式

/* Formats
 * Most of these names have the following convention:
 *      A = Alpha
 *      R = Red
 *      G = Green
 *      B = Blue
 *      X = Unused Bits
 *      P = Palette
 *      L = Luminance
 *      U = dU coordinate for BumpMap
 *      V = dV coordinate for BumpMap
 *      S = Stencil
 *      D = Depth (e.g. Z or W buffer)
 *      C = Computed from other channels (typically on certain read operations)
 *
 *      Further, the order of the pieces are from MSB first; hence
 *      D3DFMT_A8L8 indicates that the high byte of this two byte
 *      format is alpha.
 *
 *      D3DFMT_D16_LOCKABLE indicates:
 *           - An integer 16-bit value.
 *           - An app-lockable surface.
 *
 *      D3DFMT_D32F_LOCKABLE indicates:
 *           - An IEEE 754 floating-point value.
 *           - An app-lockable surface.
 *
 *      All Depth/Stencil formats except D3DFMT_D16_LOCKABLE and D3DFMT_D32F_LOCKABLE indicate:
 *          - no particular bit ordering per pixel, and
 *          - are not app lockable, and
 *          - the driver is allowed to consume more than the indicated
 *            number of bits per Depth channel (but not Stencil channel).

看到其中没有yuv420p,所以我们需要自己添加枚举,但是怎么定义yuv420p网上找不到具体的方法,

https://www.fourcc.org/yuv.php 这个位置有规范了yuv的fourcc code  

须知 yuv420p 又分为yu12 和yv12  

yu12 在安卓下双称I420

 yv12

 所以我们在上面说的网址中查表添加两个枚举

    D3DFMT_YUV420P_YU12                = 0x30323449,
    D3DFMT_YUV420P_YV12                = 0x32315659,

然后就可以愉快的使用surface渲染yuv420p了

向雷神致敬.
