Function fermium::renderer::SDL_UpdateNVTexture

pub unsafe extern "C" fn SDL_UpdateNVTexture(
    texture: *mut SDL_Texture, 
    rect: *const SDL_Rect, 
    Yplane: *const u8, 
    Ypitch: c_int, 
    UVplane: *const u8, 
    UVpitch: c_int
) -> c_int

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.

• 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.
• Returns: 0 on success, or -1 if the texture is not valid.
