Update a rectangle within a planar NV12 or NV21 texture with new pixels.
int SDL_UpdateNVTexture(SDL_Texture *texture,
const SDL_Rect *rect,
const Uint8 *Yplane, int Ypitch,
const Uint8 *UVplane, int UVpitch);
|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 UV plane.
|the number of bytes between rows of pixel data for the UV plane.
Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
You can use SDL_UpdateTexture() as long as your pixel data is a contiguous block of NV12/21 planes in the proper order, but this function is available if your pixel data is not contiguous.
This function is available since SDL 3.0.0.
