NAME¶

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

SYNOPSIS¶

#include "SDL3/SDL.h"

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);

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 0 on success or a negative error code on failure; call

SDL_GetError () for more information.

AVAILABILITY¶

This function is available since SDL 3.0.0.
