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.

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.

for more information.

This function should only be called on the main thread.

This function is available since SDL 3.2.0.
