-// We found an issue where the ID3D11VideoDecoder won't release its underlying

-// Therefore, when checking whether we can use hardware decoding, we should use

-// leaking that can significantly degrade the performance. For the actual
-// decoding, we will still use the compositor device if it's avaiable in order
-// to avoid video copying.
