Update a rectangle within a planar YV12 or IYUV texture with new pixel data.
int SDL_UpdateYUVTexture(SDL_Texture * texture,
const SDL_Rect * rect,
const Uint8 *Yplane, int Ypitch,
const Uint8 *Uplane, int Upitch,
const Uint8 *Vplane, int Vpitch);
|the texture to update
|a pointer to the rectangle of pixels to update, or NULL to update the entire texture
|the raw pixel data for the Y plane
|the number of bytes between rows of pixel data for the Y plane
|the raw pixel data for the U plane
|the number of bytes between rows of pixel data for the U plane
|the raw pixel data for the V plane
|the number of bytes between rows of pixel data for the V plane
Returns 0 on success or -1 if the texture is not valid; call SDL_GetError() for more information.
You can use SDL_UpdateTexture() as long as your pixel data is a contiguous block of Y and U/V planes in the proper order, but this function is available if your pixel data is not contiguous.
This function is available since SDL 2.0.1.
