ZoneMinder Forums

Hi all

I have just made a free install of Zoneminde on my Ubuntu 14.10 the easy way. The hardware is a Pentium 4 with 4 GB of memory.
uname -a Linux Zoneminder 3.16.0-28-generic #38-Ubuntu SMP Fri Dec 12 17:37:40 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

My camera that I'm using right now is "Foscam"ish like FI8916, FI8904 and FI8905 and some IP cam that looks like Foscam. It's very stable and is running without any problem what so ever.

But yesterday I got a new Escam QD300 "Brick" camera, and according to various sources on the internet, this camera will work with Zoneminder 1.28.
1) http://www.amazon.com/Escam-Peashooter- ... Descending
2) http://digdilem.org/cameras/?action=view&id=158

My setup is this:
Source type: Ffmpeg
Source Path: rtsp://172.31.3.7:554//user=visitor&password=&channel=1&stream=0.sdp?
Remote Method: RTP/Unicast
Colorspace: 24 Bit
1024/720

The QD300 camera has been setup from a Windows 7 and IE. And It's running perfectly within an IE browser. Most of the setting is default, just some DHCP stuff, and text removed from the GUI

Well I'm able to get a picture from the camera, but it's static. Like it's only updating each 30 sec. (not very live)

My log is showing this: (look for NewDriveway and 172.31.3.7)

Things to try:

End your Source Path with ?tcp to force the use of TCP

Turn down the frame rate (try 5 or less) and image quality on the camera. If you get "smearing" adjust the key frame rate to send a full image more often.

It is stopping because it is unable to decode the frame. Of course, the million dollar question is why.

Your cpu looks a little weak for seven cameras, especially if you are using a source type of ffmpeg or libvlc to decode each stream.
To verify this is not a resource issue, disable all cameras (make sure and set the function to "none") except for the one in question.
Verify the camera is set to a reasonable frame rate like your other cameras (~8 is perfect).

Does the camera work now or do you get the same error?

Hi all

@bbunge
that didn't change anything

@knnniggett
All cameras has been set to "None" but the result is still the same. Same entry in the log file
Some years ago I did try with a total of 11 cameras, all MJPEG, without any problem.

Hi all

I have been down the performance route, and it didn't help.
An Sun X4150 with dual Quad Core Intel CPU and 32 GB of memory, and a fast SAS drive did not make the camera more useable.

Fresh installed with Ubuntu 14.10 64 bit, and no other camera that the Escam produce the same error log.
Damn it would be nice if anyone out there did use the same camera and was able to share some info on how to set up the camera side, as well as the ZM side.

Appreciate any help!

Hi all
just want to update you with my latest finding.

I made an experiment, I got hold of my Sun X4150 server once again, and made a new installation of CentOS 6 by following this guide: http://www.if-not-true-then-false.com/2 ... tallation/

I'm 100% sure that any guide would have done the trick.
After making sure that the sever was updated, I made the Zoneminder install by following this guide: https://blog.yibi.org/tag/zoneminder-centos

Now my camera is working with Ffmpeg! No losing connection or other errors in the log file. I had it running for more than four hours without any glitch
The difference between the installation is Ubuntu/CentOS. Zoneminder is 1.28.1 on both servers
Just to make sure that running on CentOS made the difference, I tested with my normal Zoneminder server running Ubuntu and ZM 1.28.1. And very reliable it did produce the error: zmc_m7[21369].FAT-zm_ffmpeg_camera.cpp/262 [Unable to decode frame at frame 27]

By luck I found this page: https://www.devin.cl/blog/escam-ip-camera/
Same camera as mine, and running with Ubuntu. But he is using Libvlc, so that made my try the same thing, and what do you know! It's kind of working, but the frame rate is under the floor rendering that solution not useable!

Any one having an idea on why that is?

I appreciate any help/hints etc...

Lars

Nice work.

My guess as to the root cause of the problem was Ubuntu's choice of ffmpeg library. Ubuntu has chosen to ship with a library called libav. It claims to be compatible with ffmpeg, but it is not 100% compatible. This makes developing zoneminder difficult since we try to support both as best as we can. While zoneminder will technically work with libav, ffmpeg contains a few newer/different function calls that zoneminder makes use of. The issue with your camera has probably got something to do with that.

I'm not sure I understand what you mean by "the frame rate is under the floor rendering that solution not useable".

Hi Knnniggett

what I meant was that the frame rate was very low, and I somehow can't use the solution if the frame rate is under 1 per sec.

Right now I can see that the load on the server is very high 6.00

From top:
%Cpu(s): 94.0 us, 2.3 sy, 0.0 ni, 0.0 id, 0.0 wa, 0.0 hi, 3.6 si, 0.0 st
KiB Mem: 3587832 total, 3321548 used, 266284 free, 674380 buffers
KiB Swap: 3657724 total, 89516 used, 3568208 free. 1712128 cached Mem

So the solution with Libvlc is not the best!

Lars

There's a still a gap with libvlc. I got it working at one point but subsequent upgrading broke it. I suggest sticking with ffmpeg for now.
