We are developing a Windows application using the Windows SDK and the INormalVideoRenderElement. When a user joins the meeting with video disabled the video element shows the user name in the center of the render element as expected. If the user then enables their video during the meeting the video does not render in the element. It displays a black screen with their name showing in the lower left hand corner of the element. If they join the meeting with video and then turn it off and on the element renders properly. Is there something we are missing that needs to happen to get the video to render properly?
We are using version 5.0.24433.0616 of the SDK.
