3a99517f7c d3d11videosink: Avoid switching conversion tool during playback
Decoder might be able to copy decoded texture to the other buffer pool
during playback depending on context. In that case, copied one
has no D3D11_BIND_DECODER bind flag.

If we used ID3D11VideoProcessor previously for decoder texture,
and incoming texture supports ID3D11VideoProcessor as well even if it has no
D3D11_BIND_DECODER flag (having D3D11_BIND_RENDER_TARGET for example),
allow zero-copying instead of using our fallback texture.

Frequent conversion tool change (between ID3D11VideoProcessor and generic shader)
might result in inconsistent image quality.

5b3e316039 d3d11: Port to C++
Direct3D11 objects are COM, and most COM C APIs are verbose
(C++ is a little better). So, by using C++ APIs, we can make code
shorter and more readable.
Moreover, "ComPtr" helper class (which is C++ only) can be
utilized, that is very helpful for avoiding error-prone COM refcounting
issue/leak.
