Function SDL_UpdateNVTexture 

pub unsafe extern "C" fn SDL_UpdateNVTexture(
    texture: *mut SDL_Texture,
    rect: *const SDL_Rect,
    Yplane: *const Uint8,
    Ypitch: c_int,
    UVplane: *const Uint8,
    UVpitch: c_int,
) -> bool

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

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.

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 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.

Availability

This function is available since SDL 3.2.0.
