EVR Dshow filter and DXVA2.0 API

$

Hi,

I am trying to use DXVA2 for decode video acceleration under vista. I have a DirectShow decoder filter (MPEG2 and works for XP with dxva1.0).  I have the following issues.

1) I was under the impression that dxva1 to dxva2 will happen automatically when we use EVR filter. But it looks like the filter is decoding in pure software mode when using EVR and dxva1.

2) I am trying to implement DXVA2 api's by using the IMFGetService interface. But I am failing on getting the IDirectXVideoAccelerationService interface. It returned E_NOINTERFACE. Why this is happening?

3) The sample dxva2.0 playback code which comes with Windows SDk uses D3d to initialize DXVA2. But is there any way to get the Service Interfaces from EVR filter. I was unable to get much documentation regarding those details. If there is any please give me some pointers.
