您无法直接显示。你需要将其转换为RGB纹理。正如您从***中收集到的，YUV颜色空间有许多变化。确保您使用的是正确的。

You can't display it directly. You'll need to convert it to an RGB texture. As you may have gathered from Wikipedia, there are a bunch of variations on the YUV color space. Make sure you're using the right one.

对于每个像素，从YUV到RGB的转换是一种直接的线性变换。

For each pixel, the conversion from YUV to RGB is a straightforward linear transformation. You just do the same thing to each pixel independently.

将图像转换为RGB后，您可以通过创建纹理来显示它。您需要致电 glGenTextures（） 分配纹理句柄， glBindTexture（） 将纹理绑定到渲染上下文， glTexImage2D（） 以将纹理数据上传到GPU。要渲染它，你再次调用 glBindTexture（），然后渲染一个纹理坐标设置正确的四边形。

Once you've converted the image to RGB, you can display it by creating a texture. You need to call glGenTextures() to allocate a texture handle, glBindTexture() to bind the texture to the render context, and glTexImage2D() to upload the texture data to the GPU. To render it, you again call glBindTexture(), followed by the rendering of a quad with texture coordinates set up properly.

// parameters: image:  pointer to raw YUV input data
//             width:  image width (must be a power of 2)
//             height: image height (must be a power of 2)
// returns: a handle to the resulting RGB texture
GLuint makeTextureFromYUV(const float *image, int width, int height)
{
    float *rgbImage = (float *)malloc(width * height * 3 * sizeof(float));  // check for NULL
    float *rgbImagePtr = rgbImage;

    // convert from YUV to RGB (floats used here for simplicity; it's a little
    // trickier with 8-bit ints)
    int y, x;
    for(y = 0; y < height; y++)
    {
        for(x = 0; x < width; x++)
        {
            float Y = *image++;
            float U = *image++;
            float V = *image++;
            *rgbImagePtr++ = Y                + 1.13983f * V;  // R
            *rgbImagePtr++ = Y - 0.39465f * U - 0.58060f * V;  // G
            *rgbImagePtr++ = Y + 2.03211f * U;                 // B
        }
    }

    // create texture
    GLuint texture;
    glGenTextures(1, &texture);

    // bind texture to render context
    glBindTexture(GL_TEXTURE_2D, texture);

    // upload texture data
    glTexImage2D(GL_TEXTURE_2D, 0, 3, width, height, 0, GL_RGB, GL_FLOAT, rgbImage);

    // don't use mipmapping (since we're not creating any mipmaps); the default
    // minification filter uses mipmapping.  Use linear filtering for minification
    // and magnification.
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);

    // free data (it's now been copied onto the GPU) and return texture handle
    free(rgbImage);
    return texture;
}

要呈现：

glBindTexture(GL_TEXTURE_2D, texture);

glBegin(GL_QUADS);
    glTexCoord2f(0.0f, 0.0f); glVertex3f( 0.0f,  0.0f, 0.0f);
    glTexCoord2f(1.0f, 0.0f); glVertex3f(64.0f,  0.0f, 0.0f);
    glTexCoord2f(1.0f, 1.0f); glVertex3f(64.0f, 64.0f, 0.0f);
    glTexCoord2f(0.0f, 1.0f); glVertex3f( 0.0f, 64.0f, 0.0f);
glEnd();

别忘了调用 glEnable（GL_TEXTURE_2D）在初始化期间的某个时间点，并在关闭期间调用 glDeleteTextures（1，& texture）。

And don't forget to call glEnable(GL_TEXTURE_2D) at some point during initialization, and call glDeleteTextures(1, &texture) during shutdown.
