HEADER FILE

       Defined in SDL3/SDL_render.h

SYNOPSIS

       #include "SDL3/SDL.h"

       bool SDL_UpdateNVTexture(SDL_Texture *texture,
                            const SDL_Rect *rect,
                            const Uint8 *Yplane, int Ypitch,
                            const Uint8 *UVplane, int UVpitch);

DESCRIPTION

       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.

FUNCTION PARAMETERS

       texture
              the texture to update.

       rect   a pointer to the rectangle of pixels to update, or NULL to update the entire texture.

       Yplane the raw pixel data for the Y plane.

       Ypitch the number of bytes between rows of pixel data for the Y plane.

       UVplane
              the raw pixel data for the UV plane.

       UVpitch
              the number of bytes between rows of pixel data for the UV plane.

RETURN VALUE

       Returns true on success or false on failure; call

       SDL_GetError () for more information.

THREAD SAFETY

       This function should only be called on the main thread.

AVAILABILITY

       This function is available since SDL 3.2.0.
