KSPROPERTY_DISPLAY_ADAPTER_GUID
The KSPROPERTY_DISPLAY_ADAPTER_GUID property returns the adapter GUID from the capture minidriver.
To use VRAM transport, a capture minidriver must support this property.
Usage Summary Table
| Get | Set | Target | Property descriptor type | Property value type |
|---|---|---|---|---|
| Yes | No | Pin | KSPROPERTY | GUID |
Return value
A KSPROPERTY_DISPLAY_ADAPTER_GUID property returns STATUS_SUCCESS to indicate that it has completed successfully. If the Property Type Value is incorrect, it returns STATUS_INVALID_PARAMETER.
Remarks
The minidriver should return the adapter identifier of the first head on the GPU.
The capture GUID uniquely identifies a VRAM subsystem with which the capture device is compatible. The system-supplied kernel-streaming (KS) proxy module (KsProxy) uses this GUID to allocate surfaces on a compatible VRAM subsystem.
AVStream matches this GUID with the GUID of the downstream render pin to verify that both capture and render pins are on the same graphics adapter.
