Some Vivotek camera factory defaulted codec is SVC (Scalable Video coding) which is an extension of H264 that we do not support. When the camera is in this mode, the plugin fails to stream video and stays in the “connecting” state. Also were not be able to change the codec setting from the client. The only work around is to go to the camera’s web page change the codec to H264/jpeg and reconnect the camera from our client. This affects model IP8162.
