Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_video_encoder_intra_refresh_0080)

Description

The D3D12DDI_VIDEO_ENCODER_INTRA_REFRESH_0080 structure specifies the parameters for the intra-refresh mode that should be used when triggering intra-refresh sessions.

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.

See D3D12 video encoding for general information.
