_DXGKARG_SETVIDPNSOURCEVISIBILITY structure

Description

The DXGKARG_SETVIDPNSOURCEVISIBILITY structure contains arguments for the DxgkDdiSetVidPnSourceVisibility function.

Members

`VidPnSourceId`

An integer that identifies a video present source on the display adapter.

`Visible`

A Boolean value that specifies whether the video output codec associated with the source must start scanning or stop scanning the source's primary surface. If Visible is TRUE, the codec must start scanning.

If Visible is FALSE, the codec must stop scanning. However, a VSync signal should be generated even if a call to the DxgkDdiSetVidPnSourceVisibility function sets Visible to FALSE.
