OPMGetVideoOutputForTarget function (opmapi.h)

Returns a video output object for the VidPN target on the specified adapter.

Syntax

HRESULT OPMGetVideoOutputForTarget(
  [in]  LUID                       *pAdapterLuid,
  [in]  ULONG                      VidPnTarget,
  [in]  OPM_VIDEO_OUTPUT_SEMANTICS vos,
  [out] IOPMVideoOutput            **ppOPMVideoOutput
);

Parameters

[in] pAdapterLuid

The LUID for the adapter where the target is located.

[in] VidPnTarget

Target ID for the target on the specified adapter.

[in] vos

A member of the OPM_VIDEO_OUTPUT_SEMANTICS enumeration.

[out] ppOPMVideoOutput

Receives a pointer to an IOPMVideoOutput pointer. The caller must release this pointer.

Return value

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

The IOPMVideoOutput interface has two modes of behavior, depending on the value of the vos parameter. If vos is OPM_VOS_COPP_SEMANTICS, IOPMVideoOutput uses COPP semantics. This mode is intended for backward compatibility with COPP. If vos is OPM_VOS_OPM_SEMANTICS, IOPMVideoOutput uses the newer OPM semantics. Differences in behavior are noted on the reference page for each method. The mode does not change during the lifetime of the object.
