Specifies how the output alpha values are calculated for blit operations when using Microsoft DirectX Video Acceleration High Definition (DXVA-HD).
Specifies the alpha fill mode, as a member of the DXVAHD_ALPHA_FILL_MODE enumeration.
If the FeatureCaps member of the DXVAHD_VPDEVCAPS structure does not contain the DXVAHD_FEATURE_CAPS_ALPHA_FILL flag, the alpha fill mode must be set to DXVAHD_ALPHA_FILL_MODE_OPAQUE.
The default state value is DXVAHD_ALPHA_FILL_MODE_OPAQUE.
Zero-based index of the input stream to use for the alpha values. This member is used when the alpha fill mode is DXVAHD_ALPHA_FILL_MODE_SOURCE_STREAM; otherwise, the value is ignored.
To get the maximum number of streams, call IDXVAHD_Device::GetVideoProcessorDeviceCaps and check the MaxStreamStates member of the DXVAHD_VPDEVCAPS structure.
