I have managed to get it to work after some trials.
This put me on the trail:
Sound URL - http://admin:YWRtaW4=@MYIP:8080/stream/audio/wavpcm
Video URL - http://admin:YWRtaW4=@MYIP:8080/stream/video/mjpeg
This set up is assuming the password of admin is used. Use base64 - https://www.base64decode.org/
Testing in the browser with <http://admin:YWRtaW4=@192.168.0.xxx:8080> resulted in video and audio playing!
Step 1: Add Camera and select Network (IP) Camera - Other
Step 2: Select "Use Sighthound Video to help me..."
Step 3: Select "My Camera does not appear in the list..." NOTE Even if it does appear!!!!
Step 4: Select Other IP Camera, http protocol, IP address, port 8080, stream path: stream/video/mjpeg, username, password in base64 (not text!!!, YWRtaW4= corresponds to default password=admin)
Haven't gotten audio to work though.
Good luck
