Provide the ability to monitor directly connected USB cameras
Yes, please. I'm actually deciding between several options and this is a strong point.
You already do! You can easily convert an USB camera to RTSP, both h264 and MJPEG. I'm actually monitoring 2 of them.
Should you help me with a license key, I would happily write a HOWTO on the subject.
I would really be interested in knowing how you can do this!
