Header file
Defined in SDL3/SDL_render.h
Overview
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.

- rect
-
a pointer to the rectangle of pixels to update, or NULL to update the entire texture.
- Yplane
-

- 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 true on success or false on failure; call
SDL_GetError () for more information.
