> My setup is a dericam IP camera (A) with an rtsp server on a subnet
> (rtsp://Aip:554/12). On the same subnet, there is a server (L) running
> live555proxyServer exporting A's rtsp stream as
> rtsp://l555ip:8554/proxyStream-1.
>
> There is another (janus) server (J) that supports webrtc and exports J's
> rtsp to a browser on another subnet.

> In general, things work fine. However, when I start viewing the stream
> through janus, and then stop viewing the stream, and then let things sit
> for a while, then try to start viewing the stream again, I do not get image
> data all the way through to janus.

> It may be a janus problem, it may be a live555 problem, or it may be a

> When I get into the situation where I seem (from a janus and live555
> perspective) to be able to talk to the camera, but still not get image
> data, I tried running vlc on the same subnet as live555 and the camera.
> Looking at vlc, I can see the camera's image data, but looking at the
> live555 port I cannot. (When everything is working fine, I can see (using
> vls and janus) the camera's image data both directly with the camera and
> through live555.)
>
> So, this makes me think janus is not the culprit, but something I have done
> has put the live555 and camera in an undesirable state.
