Cheap IP camera with 1920×1080 resolution.
General -> Source type = Ffmpeg
Source -> Source path: rtsp://admin:20160404@<ip>:554/onvif1
Source -> Remote Method: RTP/Unicast
Capture width: 1920
Capture height: 1080
There is smearing on the bottom part of the image about half the time.
Most people on the internet recommends switching to TCP to avoid smearing, but I have been unable to get this camera working over TCP.
