typedef struct D3DWDDM2_4DDIARG_VIDEODECODERBEGINFRAME {
  D3D11_1DDI_HVIDEODECODEROUTPUTVIEW    hOutputView;
  const void                            *pContentKey;
  UINT                                  ContentKeySize;
  D3DWDDM2_4DDI_VIDEO_DECODER_HISTOGRAM Histograms[D3DWDDM2_4DDI_VIDEO_DECODER_MAX_HISTOGRAM_COMPONENTS];
} D3DWDDM2_4DDIARG_VIDEODECODERBEGINFRAME;

Members

hOutputView
