IVMRMixerControl::GetOutputRect method (strmif.h)

The GetOutputRect method retrieves the position of this stream's video rectangle within the composition rectangle.

Syntax

HRESULT GetOutputRect(
  [in]  DWORD          dwStreamID,
  [out] NORMALIZEDRECT *pRect
);

Parameters

[in] dwStreamID

Specifies the input stream.

[out] pRect

Pointer to a NORMALIZEDRECT structure that receives the destination rectangle in composition space.

Return value

If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Return code Description
E_POINTER
pRect is invalid.
VFW_E_NOT_CONNECTED
The pin is not connected.

Remarks

Because this rectangle exists in compositional space, there is no such thing as an "invalid" rectangle. For example, if left is greater than right, it means the video is mirrored in the x direction. An empty rectangle turns off this stream.
