SDL_UpdateYUVTexture

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

Header File

Syntax

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);

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.

Remarks

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.

Version

This function is available since SDL 3.0.0.
