No live camera view and errors when viewing

[withanHdammit]

This is a fresh install on Debian Buster using the wiki install guide https://wiki.zoneminder.com/Debian_10_B ... om_ZM_Repo
ZM = v1.34.10
Apache = v2.4.38
PHP = v7.4.5

I have my first camera added (currently only in monitor mode), and when looking at the logs, they appear to show the camera is working. The source path works correctly when viewed in VLC, so I'm certain that is correct.

Logs when initially viewing:

When I look at the live view, it only shows a broken image and the logs start showing errors:

The logs show a lot of this:

Both of which refer to the same thing, but aren't actually helpful.
I checked the /var/run/zm and it has the appropriate permissions and is clearly creating the .sock files there:

I'm not really sure where to go from here. Any assistance is greatly appreciated!

Use VLC to check the resolution you should use.

[withanHdammit]

Both Zoneminder and the camera are configured for 1920x1080.

[bbunge]

OK, but the camera may not be using that exact resolution. Have seen it many times and is worth a check.

Camera resolution in Zoneminder does not match camera output. Use VLC (Tools, Media Information, Codec) to check camera Display Resolution.

Also, if you are on a server with low RAM use half of the camera resolution to start.

It looks like that I have exactly the same problem. Fresh install on Ubuntu 18.04 LTS. I´m searching since 4 days to find the error At first start after install of Zoneminder, I could see the live stream in the Zoneminder´s webend, so everything worked well.

Since I did the first reboot of the server it fails and I didn´t changed anything after first start of Zoneminder when it works and first reboot, not regarding hardware not at the configuration. If now I click at "console => name of the camera" the browser window changes regarding the size of the defined capture resolution (pixels) (in my example 640x380) and under it I can see the buttons to stop, continue and zoom the camera picture (which I can´t see). I also can´t play the events, which are grabbed by one camera. The pictures as jpeg are stored on the disc and I can open from a samba share, but instead of playing on the Zoneminder´s webend there is just a white space.

I´m running Firefox on Windows managing Zoneminder. However, I tried with different other browsers, no one is showing a camera stream in Zoneminder webend.

For test reasons I added just one camera with 2 rtsp streams (highres and lowres) and setup the lowres stream as capturing. This works well, I can find a lot of pictures on the disc. Also I can see both live streams in VLC as I added into Zoneminder´s configuration:
rtsp://USER:PASSWORD@192.168.50.100:554/Streaming/Channels/102

Any ideas?

[denvid]

In the Wiki section "Socket_sendto or no live streaming" I can find the hint:

From console go to Options->Path and make sure PATH_ZMS is set to /zm/cgi-bin/nph-zms.


Where can I find "PATH_ZMS"?

I wasnß t able to find in the web-backend and also not in any config-file.

Thanks!

OK, but the camera may not be using that exact resolution. Have seen it many times and is worth a check.

Camera resolution in Zoneminder does not match camera output. Use VLC (Tools, Media Information, Codec) to check camera Display Resolution.

Also, if you are on a server with low RAM use half of the camera resolution to start.

VLC codec info shows 1920 x 1080. ZM set for 1920 x 1080.

Since I am only working with one camera for now, I had the server set for 8GB RAM, but I updated it to 16GB and that did not help.

I'm on a Debian Linux server and that setting is in /etc/zm/conf.d/01-system-paths.conf

i am having the same issue.
i have a centos 7 install without issues, works fine.
i'm running proxmox 6.1 with ubuntu 20.04 lts container
everything else seems to be working in terms of database, sign in, i left the timezone as UTC, same as the host.
4 gigs of ram and only one motion detect sub stream added at 320x240 resolution.
the source is green, it even shows frames per second, but when you click on it, it only displays the broken image symbol.

the log file says to try installing cambozola, but all the download links i can find are all broken for that software, and i haven't needed to enable and download that for ages using newer browsers.

no firewall running and it does see the stream.
the stream on the camera is set to 320x240 same as ZM.
using VLC, with the exact same URL as what I have for my source, it works fine and plays.

i used the script that said it was for LTS 20/18/16 under the current ubuntu instructions.
the /etc/zm/conf.d/01-system-paths.conf has the proper path.
the /etc/zm/zm-config.conf does not.
which should be setup?

# ZoneMinder url path to the zms streaming server
ZM_PATH_ZMS=/zm/cgi-bin/nph-zms

[shores]

please see this report on a second thread.
i turned off auth (everyone should be using auth for security). and the streams work fine
only on ubuntu, mine is 20.04 lts, the other person is 18.04 lts


Everything actually works fine until I turn Authentication on. As soon as I check the box for "OPT_USE_AUTH" under Options>System, I can no longer view the streams. Log entries are below.

I´ve got it working
First step, to uncheck in webend: Option => System => OPT_USE_AUTH
Then camera live stream will be able in the web-backend

Second step, check and fix, that timezone on Ubuntu system match with php setting, e.g.:
https://linuxize.com/post/how-to-set-or ... ntu-18-04/

After restart:
service apache2 restart
service zoneminder restart

you might enter the webend without login, then you can check again
Option => System => OPT_USE_AUTH

to enable auth login.
