ZoneMinder Forums

New to zoneminder, but I now have (8) 720p@10 FPS cameras connected to a zoneminder 1.27 VM. Everything is working, motion detection, email alerts, etc., but I have to restart every 15 hours or so, or at least one of the camera streams gets "hung". Sometimes, the capture appears red, and sometimes it just won't populate a picture.

Below's a snippet from /var/log/syslog that happened around the time the camera feed went offline:

If I set the motion detection to disabled on the camera, then set it back to modect, the camera comes back, but a lot of functions seem sluggish until I reboot the zoneminder VM.

Here's a snippet from reenabling modect on a camera:

I googled around and found this:
http://www.zoneminder.com/wiki/index.ph ... esolutions.

But I'm not sure whether to go the shared or mapped memory route, how best to implement on 1.27, or even if that is really the issue.

Any ideas before I start executing commands I don't really understand?

Increased the image buffer size to 75 on all the cameras, and the ring buffer error went away. Will see if the hang still happens.

What are the camera settings, are you using ffmpeg or libvlc? I'm new to ZM too...

You want to use memory map unless you have a specific reason not to use it.

It looks like you are not using a capture method that is completely compatible with your cameras. Dont use the 'tcp' option as it has been depreciated in recent versions of libvlc and ffmpeg...I think. Are you able to stream the cams via RTSP using VLC or other software? It looks like zm simply cant talk to the cam. Also, restart zm when you make changes to the camera settings or you will end up chasing your tail.

After experiencing similar problems, I found the following works well on a 4x 1080P cameras capturing at 25 frames per second.

Source Type - Libvlc
Maximum FPS - 5 (monitoring zones at 5 FPS to reduce CPU load)
Alarm FPS - 15 (recording at 15 FPS to reduce storage demand)

Source Path - rtsp://xxx.xxx.xxx.xxx
Target Colorspace - 24 bit
Capture Width - (720P = 1280) or (1080P = 1920)
Capture Height - (720P = 720) or (1080P = 1080)

Image Buffer Size (frames) - 50
Warmup Frames - 25
Pre Event Image Count (frames) - 25
Post Event Image Count (frames) - 25

I would recommend setting up a single camera in 'monitor' function before adding more cameras.

Once an image can be viewed on all camera in 'monitor' function, progressively switch each camera to 'modetect' with limited zone coverage.

Small tip: Many cameras seem to advertise audio as an option even if they don't actually provide audio and even if they do you cant do anything with it on zm so adding an option to ffmpeg of "allowed_media_types=video" seems to aid in stability. I am not sure if a similar option is available for libvlc as I am getting better results and lower overhead with ffmpeg on my new build.

The Maximum FPS and Alarm Maximum FPS fields are intended for local cameas only. For IP cameras, do not place values into these fields. Doing so introduces undesrieable side effects that may not be immediately noticed. Significant lag is introduced into the live view and entire motion events are missed.

Maybe you are already aware, if one has libjpeg-turbo installed on the system you can switch the color space to 32bit for a significant performance boost.

How do you confirm if libjpeg-turbo is installed and active within Ubuntu 12.04?

Thank you.

Easiest way to see if ZM found the libs and was built against them is to use ldd on one of the binary files. Find the dir where 'zmc' is located and do "ldd zmc | grep turbo" and see if libjpeg-turbo shows up.

One thing to keep in mind is many IP cams can only support two streams at a time so if you are feeding a stream to ZoneMinder and accessing it directly you can get the oldest stream to be ended to supply the newer ones. If you use a mobile app to watch the cams streams set it up to pull the stream from ZoneMinder instead of going direct to the can unless you know you won't max out the cams capability to feed multiple sources at the same time.

I finally got my libvlc to work but when I tried "ldd zmc | grep turbo" in my /usr/bin folder i got no message.

Can I just edit it in? I got my libvlc to finally start working when I followed this http://lachlanmiskin.com/blog/2012/06/2 ... rker-0xd9/

using
sudo apt-get install dpkg-dev
sudo apt-get build-dep libjpeg-turbo
apt-get source libjpeg-turbo
cd libjpeg-turbo-1.1.90+svn733
cp -p jdmarker.c jdmarker.c.orig
vi jdmarker.c
dpkg-buildpackage -rfakeroot -uc -b
sudo dpkg -i ~zmadmin/libjpeg-turbo8_1.1.90+svn733-0ubuntu4.1_i386.deb
sudo service zoneminder restart

with some errors at after the dpkg-buildpackage -rfakeroot -uc -b and the one after that.

But it did get my VLC to start working...just no turbo, and no errors so far....

No, don't do that. Sorry if I overlooked it, half asleep, but what distro are you running and what version of ZoneMinder are you using? Built from source or installed with a package?

You are running this in a VM? I have a few VM images that are ripe to build the current ZoneMinder code with all the goodies. When I get a few minutes I can clean up my 14.04 x86_64 image and share it. It uses turbo, recent libvlc, a good ffmpeg with x264, etc. I use the same confg on my physical servers and it works extremely well.

Im using Ubuntu 12.04 and zm 1.27 on a dedicated server. No VM.

Well as far as the errors go they returned and the picture on the libvlc started making wierd pixel shifts (dont know how to describe) so
I'm back to using ?tcp....thought maybe this libturbo would be my answer to get the libvlc working instead of ffmpeg.

Ahh. I wasn't sure. You said "..connected to a zoneminder 1.27 VM" so I thought it might be running in a virtual machine.
