ZM 1.36 RTSP Remote capturing but not showing video

[F1R35pirit]

I have a PTZ camera from AliExpress. I guess it is CamHi IPCAM C6F0SpZ3N0PlL2.
I have no problems connecting to it via VLC or via ONVIF Device Manager, the latter also successfully controls the PTZ functions.

The device's stream url is rtsp://172.17.71.32:554/11, and there is also a secondary stream at /12

With ZM 1.36, however, I'm struggling to make it work. I have configured a "monitor" with the following parameters:

• General:
  • Source Type: Remote
  • Function: Monitor
• Source:
  • Protocol: RTSP
  • Method: RTP/Unicast (I've also tried other, but they produce even worse results)
  • Host Name: 172.17.71.32 (somehow it doesn't actually work with a hostname here, only with ip address)
  • Port: 554
  • Path: /11
  • Capture Resolution: 2560x1440 1440p QHD WQHD

I guess other settings are irrelevant. With the above settings I get the following:

• On the "Console" page I see "Capturing" in the "Function" column, but a broken image icon in the "Name" column.
• On the "Log" page I see a lot of messages like this:

  Code: Select all

• On the monitor's page that opens when I click on monitor's name, I see a blank page with the standard "broken image" icon and some standard header and footer.

What am I doing wrong? How can I make it work?

P.S. Just for reference, the camera is this: https://aliexpress.ru/item/1005008018786467.html

Source Path: rtsp://user:password@172.17.71.52:554/11
Method: TCP

And make sure the resolution matches the cam settings! To get started set the cam main stream to 720P or 1080P

I suspect you are not using ZM 1.36 as some of your settings do not appear in ZM 1.36.36

I suspect you are not using ZM 1.36

This is what my apt says:

Code: Select all

# apt show zoneminder
Package: zoneminder
Version: 1.36.33+dfsg1-1build4
...

Source Path: rtsp://user:password@172.17.71.52:554/11
Method: TCP

There is no such method for 'Remote' source type in my ZM. Did you mean some other source type?

set the cam main stream to 720P or 1080P

1080P is the least my camera can do, but it doesn't help. Still no picture.

Source Path: rtsp://user:password@172.17.71.52:554/11
Method: TCP

I tried this with 'ffmpeg' source type, and the result is exactly the same as with 'Remote'/'RTSP': "capturing" in the console window and in the logs, but no actual picture.

Looks like my setup is somehow broken, because when I tried to open the URL that my ZM uses to show the picture:

Code: Select all

http://myzmhost.mydomain.tld/zm/cgi-bin/zms?scale=75&mode=jpeg&maxfps=30&monitor=1&rand=323286&connkey=927939

all I got was... an ELF file! So it looks like CGI apps are served as usual files instead of being executed.

[F1R35pirit]

Turned out, the CGI module wasn't enabled for my apache2. Yet another 'peculiarity' of ZM installer. I would expect the installer to make the product ready for use, but first I had to manually create the mysql user and the databse, now this...

For anyone having the same problem, do this:

Code: Select all

sudo a2enmod cgi
sudo systemctl restart apache2
