309a940614 d3d11decoder: Do negotiation again per forward/reverse playback mode change
For reverse playback, we are always copying decoded
frame to downstream buffer. So the pool size can be
and need to be large enough.

In case that forward playback, however, we need to restrict
the max pool size for performance reason. Otherwise decoder
will keep copying decoded texture to downstream buffer pool
if decoding is faster than downstream throughput
performance and also there are queue element between them.

78e4251750 Revert "d3d11vp9dec: Add support for internal frame resizing"
This reverts commit 58a4c33a0e

We should use ID3D11VideoProcessor instead of shader
to avoid copy. We need to revisit this topic later

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.
