NAME
SDL_UpdateYUVTexture - Update a rectangle within a planar YV12 or IYUV texture with new pixel data.
SYNOPSIS
#include <SDL3/SDL_render.h>
bool SDL_UpdateYUVTexture(SDL_Texture *texture,
const SDL_Rect *rect,
const Uint8 *Yplane, int Ypitch,
const Uint8 *Uplane, int Upitch,
const Uint8 *Vplane, int Vpitch);
DESCRIPTION
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.
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.
Uplane the raw pixel data for the U plane.
Upitch the number of bytes between rows of pixel data for the U plane.
Vplane the raw pixel data for the V plane.
Vpitch the number of bytes between rows of pixel data for the V plane.
RETURN VALUE

THREAD SAFETY
This function should only be called on the main thread.
AVAILABILITY
This function is available since SDL 3.2.0.
