Hi,
We are developing a hardware video decoder and would like to support
it under Windows Vista (if possible in XP too if there exists a driver
model which supports both). We would like to enable DXVA support on
this driver so that any DXVA (2.0 or 1.0) aware applications
(including Filters for DirectShow or Media Foundation) can use it.
I read lot about DXVA support in display hardware and its driver but
unable to find a similar situation where the hardware does only video
decode and no display. Is it possible to write a driver under WDDM (or
under any driver framework or as a standalone driver) which can export
a driver interface required by DXVA so that applications using
IDirectXVideoDecoderService interface will be interacting with driver
for our hardware?
Thanks!
