I bought a foscam fi9900p today, and I am trying to get the live stream into opencv, I had a hikvision before and I added this and it worked "rtsp://admin: pass@1IP/doc/page/previw.asp", I googled how to do it on Foscam, and it said to do this "rtsp://admin: pass@1IP: port/videoMain", but when I run it on OpenCV i keep getting "Missing reference picture, default is 65536" as multiple messages. How can I fix this?
