NAME¶

SDL_UpdateNVTexture - Update a rectangle within a planar NV12 or NV21 texture with new pixels.

SYNOPSIS¶

#include "SDL3/SDL.h"

int 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 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.
