The GetOutputRect method retrieves the position of this stream's video rectangle within the composition rectangle.
HRESULT GetOutputRect( DWORD dwStreamID, NORMALIZEDRECT* pRect );
[in] Specifies the input stream.
[out] Pointer to a NORMALIZEDRECT structure that receives the destination rectangle in composition space.
If the method succeeds, it returns S_OK. If it fails, it returns an error code.
|E_POINTER||pRect is invalid.|
|VFW_E_NOT_CONNECTED||The pin is not connected.|
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.
