Can't see my cam video but can record it?

[milesnz]

Hi,

I am not able to see my camera feed when in Monitor mode - but when I switch it to Record mode then it records and I can play it back in the montage window.
There is definitely data flowing because I can see the Network Receiving stats happening at about 300kbs.
I've tried all possible settings, including trying from another pc in the house, trying IE and also Chrome, on Windows and also on Linux.
What have I done wrong?

When I load the mrl into VLC I can see the video feed no problem.

Milesnz,

From /zm/index.php, click on Log

Leave that window open, and then try to view a monitor. Do any recent log entries appear? Anything that might help clue you into what may be happening?

Also, so that others here can get a bigger picture, please do the following:

From /zm/index.php, click on the Source that is giving you trouble.
Look at the top left of that windows -- There should be some blue text that starts with "Monitor - " followed by the monitor name and a number in parenthesis. Make note of that number.
Get a terminal prompt on your Zoneminder server (ssh works well for this).
Issue this command:
curl -k https://127.0.0.1/zm/api/monitors/NUMBER.json
where NUMBER is the number within the parenthesis.
I.E. if the number is 2:
curl -k https://127.0.0.1/zm/api/monitors/2.json

That should output all of the settings for that monitor -- just copy and paste that here (preferably within a CODE block).

The only thing else I can think of to try is to give us the Codec Information that VLC has while viewing your stream. We can verify that you've got the right dimensions, etc from that.

Hi,

Did you change the port to :554? Normally rtsp:\\ uses port :8554

[milesnz]

Hi jkemp, according to wiki the default port for rtsp is 554 and 8554 is an alternate port. I didn't change it myself to 554, it came as the default.

Hi SteveGilvarry,
That worked - for some reason the path in options was set to /cgi-bin/nph-zms instead of /zm/cgi-bin/nph-zms.
Awesome, thanks for all the help and advice everyone.
