Comment (by msiders):

 Hi,

 Regarding the use of D3D11 or D3D9 with the QSV accelator I noted this:

 - The current QSV filters, have support for both types of handles.
   See as example:
 https://github.com/FFmpeg/FFmpeg/blob/master/libavfilter/qsvvpp.c#L74

 - But the hardware device initialization for QSV only has support for
 D3D9.
   See the code:
 https://github.com/FFmpeg/FFmpeg/blob/master/libavutil/hwcontext_qsv.c#L93

 So I figure that the hwcontext for QSV needs to add support for handles
 with D3D11. Then the offscreen processing will be available.

 I'm right?
