Members
Mode
A D3D12DDI_VIDEO_ENCODER_INTRA_REFRESH_MODE_0080 value that indicates the type of intra refresh to be used.
IntraRefreshDuration
The duration of the intra-refresh session, in number of frames. If Mode is D3D12DDI_VIDEO_ENCODER_INTRA_REFRESH_MODE_ROW_BASED_0080, IntraRefreshDuration and the frame height define the size of the I rows for the duration of the IR session.
Remarks
When triggering an intra-refresh session, the host informs the current frame number relative to the [0..IntraRefreshDuration) session by setting IntraRefreshFrameIndex in the picture control structure.
