SDL_UpdateYUVTexture3
Update a rectangle within a planar yv12 or iyuv texture with new pixel data.
Usage
#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);
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 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.
