It's still very confusing as to how this works. I followed your instructions, but things aren't still working properly: of my two cameras, I was able to access the RTSP stream for one of them in VLC for a few moments, but can't now; the other one has never shown up.
Is this really live streaming, or is it merely streaming the last clip captured by the camera?
EDIT: okay – in addition to the instructions listed, turning off RTSP for each camera, then turning it back on, worked!
EDIT 2: It only worked for a bit. Now, when I try to access either stream, VLC shows nothing (can't connect).
