Value Description
E_INVALIDARG Coordinates not in the {0, 0, 10,000, 10,000} range.
S_OK Success.

Remarks

This method assumes window coordinates of {0, 0, 10,000, 10,000}. Therefore, if you want your video stream to be rendered in the bottom right quarter of the display window, you would call this method with the parameters {5,000, 5,000, 10,000, 10,000}.

Note Values greater than 10,000 are invalid and will cause an error.
