[Live-devel] advice and debugging a problem

[Brian Koblenz]

Ross,

I am hoping you can provide some advice as to how I might debug a problem I
am having.  It is "reasonably", but not perfectly repeatable.

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
camera problem.

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.

Do you have a suggestion as to what I should do next to further isolate the
problem?
