   DXVA2 and Direct3D
  Hi,I have a question regarding DXVA2 and render targets. I am developing a video processing application and ultimately I want to use pixel shaders (in D3D) to process video that comes out of the DXVA2 decoder.I have successfully managed to create an H264 decoder and decode video, but I run into problems when I try and change the render targets for the decoder. Ideally I want to use IDirect3DTexture9 surfaces created with IDirect3DDevice9::CreateTexture because this way I can avoid unnecessary video copies or colour space conversions. However, it seems as if only surfaces created with IDirectXVideoAccelerationService::CreateSurface will work in the decoder (note I have also tried IDirect3DDevice9::CreateOffscreenPlainSurface which fails in IDirectXVideoDecoderService::CreateVideoDecoder and  IDirect3DDevice9::CreateRenderTarget which cannot make type NV12). Please can you advise if what I am trying to do is possible and if so how.Currently I am using ATI Mobility HD 4570.Many thanks,Matthew
