SDL_UpdateYUVTexture - Update a rectangle within a planar YV12 or IYUV texture with new pixel data.

HEADER FILE

Defined in SDL3/SDL_render.h

SYNOPSIS

#include "SDL3/SDL.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

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.
