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?
