Zoneminder and Odroid XU4 - needed a working setup!

pat2 · Post by **pat2** » Sun Feb 10, 2019 7:49 pm

Any experience about Zoneminder install on Odroid XU4?

I tried 18.04 (4.14)/16.04 (4.14) provided by the hardkernel wiki and the last 18.04 Armbian for Odroid provided by a third part site. Many ZM versions. Finding issues with FFmpeg or MJpeg management. In any cases not possible to view the stream, in other cases not possible to view recorded images. No way to get a full working setup with ZM versions higher than 1.29 (i.e: 1.33 or 1.32 or 1.30.4)

The only working setup I found is ZM 1.29 and 16.04 (4.14 kernel) Ubuntu image provided by the hardkernel wiki.

I will appreciate if an XU4 owner can share his experience on ZM. I hope there will be.
thanks

Note: I'm already running Ubuntu 14.04 and ZM 1.30.4 on my old Radxa Pro. Odroid XU4 is more powerful and fast, but I'm finding issue to find a full working setup for ZM >=1.30.4

The problem is ffmpeg from HardKernel tries to use hardware decoding and it might fail. I think you can force install ffmpeg from ubuntu repos and mark hold it. Not sure what version that is though (sudo apt-get install ffmpeg=x.y.z)

pat2 · Post by **pat2** » Sun Feb 10, 2019 11:26 pm

hi Mad, thanks.

I thought something similar related to Odroid (first the image provided by Hardkernel,then something related to Odroid HW) since with the Armbian image i had less issue (but I have).

On ZM log I'm receiving error messages about difficulties of ZM when to viewing ffmpeg streams and using Hardkernel image:

Code: Select all

Unable to open codec for video stream from rtsp://admin:admin@192.168.1.200:554/1/h264minor

Or with the Armbian image solved the above issue, but when i try too review recorded mjpeg stream (probably to review recorded stream ZM> 1.29 uses ffmpeg).

That's the reason, after some unsuccessful posts in zoneminder forum, I wrote in Odroid forum!

hoping that anyone before me faced the issue and solved.

Zoneminder is the most important surveillance tool in Linux environment. And Odroid XU4 is perfect in terms of power (cpu usage passed from 5 (Radxa) to 1(Odorid XU4) in ZM console). ZM became more responsive with Odroid !I have 7 (640x480) cameras.
And so, someone before me in this forum should have been experienced with ZM.

The strange is ZM 1.29 and Hardkernel 16.04 Ububntu image are fully working. Probably ZM 1.29 doesn't require HW decoding.

I already tried to reinstall but probably I used the Harkernel repo. I will do other tempatives. And let you know.

You can try Meveric's OGST image - it comes with an older kernel and an older ffmpeg I think and should not support hardware decoding in ffmpeg.

You can also try to run ffplay -i rtsp://... and see what it complains about.

There's also a zoneminder alternative you can try - can't remember the name, something japanese sounding - was featured in odroid magazine.

Do you mean Shinobi?

That's the one, yes.

thanks guys, for the insights about the Meveric image and Shinobi.

I will try Shinobi with hardkernel ubuntu images. And I will try ZM with Meveric image too.

Zoneminder is a strong tool: it exposes a web page (so accessible in LAN and in WAN too, through portforwarding and DDNS), with authentication and https protocol through which it is possible to see all cameras.
It's possible to record video on a NAS on motion detection (with a strong parameters flexibility to detect motion) and to move cameras.
There are no constraints on type of cameras. It's really a strong tool.
The issues are tool configuration difficulties (apache, mysql, php and zoneminder itself) and possible new releases regressions (due to not easy/changing configuration): since ZM free of charge and done by volunteers there could be bugs and not a valid support.
After weeks of trials I was able to get it fully working with my 7 cameras at home (ZM 1.30.4 with ubuntu 14.04 and Radxa Pro). And for charity in an hospital on an Ubuntu 18.04 running on a server and a lot of cameras.

Odroid XU4 is very powerful: with Odroid XU4 the ZM's CPU usage was reduced at 1/5 of the previous setup on Radxa. Odroid works at home. To be checked if possible to use Odroid in the hospital (i don't think, too many cameras).
Unfortunately with Odroid XU4 I'm having issues not related to Odroid, but related to the intregration/maturity of the tool on 16.04/18.04, ARM technology and ffmpeg. The only working setup I found is 16.04/ZM 1.29 (an old ZM version). And that's the reason I was curious to know if in the forum there is anyone experienced wtih Odroid and ZM and if able to run an higher ZM version (1.30.4 or greater) on Odroid XU4

thanks regards

I really hope someone will write an article with the latest ZM + XU4 for our Magazine.

mad_ady · Post by **mad_ady** » Wed Feb 13, 2019 2:48 pm

I'd like to say "challenge accepted", since I've used both zone minder and ffmpeg before, but with so many ongoing personal projects... we'll have to see how I make more time

pat2 · Post by **pat2** » Wed Feb 13, 2019 7:04 pm

guys, thanks a lot. a ZM wiki on XU4 and ZM could be really helpful.

please Mad take in consideration that the most stable ZM release is 1.30.4. I read the ZM forum: there are many users claiming for issues on higher versions. Big changes have been made on ZM after 1.30.4 so that's the reason of not perfect stability of versions greater than 1.30.4.

To install use as reference documentation in the Zoneminder site https://zoneminder.readthedocs.io/en/la ... buntu.html# (they recently added instruction for ubuntu 18.04 too, the only difference should be the different php version to be modified for timezone (7.2 for 18.04, 7.0 for 16.04), not so important).
To install LAMP they are suggesting to use tasksel. You could also install manually php, mysql and and apache.

For the ZM package you could use the iconnor repo or use the harder way (= build from source): it's not so hard, it is only longer...
I'm not a big expert but If you want I could support you for testing.
In my next post I will write all the set of instructions I'm using to install ZM 1.29 on Hardkernel 16.04 image. It's fully working!!
The issues are on greater ZM versions: the install activity goes well, the only issue is on ffmpeg streams cameras.

thanks regards

mad_ady · Post by **mad_ady** » Wed Feb 13, 2019 8:31 pm

Do you have any public webcam streams that don't work and can be tested?

pat2 · Post by **pat2** » Thu Feb 14, 2019 2:41 am

on XU4, ZM 1.29 and 16.04 hardkernel image all is working fine.

I could prepare another enviroment (I have 2 Odroid XU4 boards) with 18.04 image and and ZM 1.32 in which ffmpeg cameras are not working. I will expose the board in WAN so you could reach the board and the cameras.
The issue is that I have to come back at home: currently I'm outside for work for 2 weeks...

Install 16.04 Image (ZM 1.29 available on 16.04 repository) : https://wiki.odroid.com/odroid-xu4/os_i ... 4/20171213

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt autoremove

install LAMP
=================================================================================================================================
sudo apt install apache2
sudo apt install mysql-server
sudo apt install php libapache2-mod-php php-mysql
=================================================================================================================================

install ZM 1.29 (no need to install iconnor repo since ZM 1.29 already available on Ubuntu 16.04 (xenial) repo)
=================================================================================================================================

sudo -i

mandatory for ZM 1.29 (not needed for ZM >=1.32 )
=================================================================================================================================
rm /etc/mysql/my.cnf (this removes the current symbolic link)
cp /etc/mysql/mysql.conf.d/mysqld.cnf /etc/mysql/my.cnf

nano /etc/mysql/my.cnf

in the [mysqld] section add the following

sql_mode = NO_ENGINE_SUBSTITUTION

systemctl restart mysql
=================================================================================================================================

apt-get install zoneminder

mandatory for ZM 1.29 (not needed for ZM >=1.32))
=================================================================================================================================
mysql -uroot -p < /usr/share/zoneminder/db/zm_create.sql
mysql -uroot -p -e "grant lock tables,alter,drop,select,insert,update,delete,create,index,alter routine,create routine, trigger,execute on zm.* to 'zmuser'@localhost identified by 'zmpass';"
=================================================================================================================================

chmod 740 /etc/zm/zm.conf
chown root:www-data /etc/zm/zm.conf
chown -R www-data:www-data /usr/share/zoneminder/

a2enmod cgi
a2enmod rewrite
a2enconf zoneminder

a2enmod expires
a2enmod headers

systemctl enable zoneminder
systemctl start zoneminder

nano /etc/php/7.0/apache2/php.ini

insert
[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York (depending on your timezone)

systemctl reload apache2

you could find ZM web page on http://IP_of_the_board/zm and add cameras (all types working: ffmpeg and mjpeg cameras connected via wifi or via ethernet cable or through USB)

===================================================================================
The same procedure is valid for Ubuntu 18.04/ZM 1.32 avoiding not needed commands for ZM 1.32.
In this case before installing ZM you have to add the iconnor repo:

add-apt-repository ppa:iconnor/zoneminder-1.32

you will be able to install a working ZM except for ffmpeg cameras.

In my next post I could explain how to go in https mode (through letsencrypt or self made certificates), how to expose in WAN (through portforwarding and DDNS on router), how to force authentication (configuration in zoneminder), how to add a NAS or external network HD and record ZM events (through fstab and bind statement)

That's half an article already.

I'll try to replicate your setup and see what the problem is.

pat2 · Post by **pat2** » Thu Feb 14, 2019 4:41 am

thanks, Mad.

For 16.04/ZM 1.29 everything is working fine: ffmpeg and mjpeg streaming, recording and record viewing.

There are issues with 18.04/1.32 (or greater) and odroid XU4 . in particular to view ffmpeg stream.
On my pc 18.04 VMware machine/ZM 1.32 (or greater) all works fine, ffmpeg too!!

thanks regards

Post by **odroid** » Thu Feb 14, 2019 9:19 am

@mad_ady will find a root cause probably.
But I guess the pre-installed MFC hardware accelerated ffmpeg package in Ubuntu 18.04 image might cause the problem.

pat2 · Post by **pat2** » Thu Feb 14, 2019 6:33 pm

thanks, Odroid.
I agree. Thinking the same.

mad_ady · Post by **mad_ady** » Fri Feb 15, 2019 8:35 pm

I managed to replicate your setup (only difference was that I needed to edit php.ini for php7.2, not 7.0).
I added a MJPEG camera (from mjpeg-streamer) that was configured as below and works correctly. Below are my settings. Can you give me yours?
https://imgur.com/a/9CKj31b

I can try with a RTSP/H264 camera as well and will post back some results.

Update:
RTSP fails to get the resource, needs more digging in the configuration:

Hi Mad,

you are right. For 18.04, php is 7.2. (the instruction I wrote are for 16.04, in 16.04 php is 7.0).

Also MJPEG camera is working for me, Able to see stream, record and to see what recorded.
For FFMpeg camera ( I have 2 types, both not working) you should have issue to see the stream.

My next post i will provide printscreen of all my camera configuration (mjpeg and ffmpeg).
thanks

mad_ady · Post by **mad_ady** » Fri Feb 15, 2019 11:31 pm

The mjpeg camera was configured as ffmpeg. I'll try to get it working with the rtsp one, but so far it was configured as "remote" and it had issues registering to the stream.

all those configurationa are working on Radxa, 14.04, ZM 1.30.4 and on Odroid XU4, 16.04, ZM 1.29.

FFMPEG not working on Odroid XU4, 18.04, ZM 1.32

mad_ady · Post by **mad_ady** » Sat Feb 16, 2019 12:55 am

The mjpeg camera configured as remote does work, right?

pat2 · Post by **pat2** » Sat Feb 16, 2019 3:02 am

correct!

the issue is on FFMPEG cameras: even if well configured, not working on 18.04 - ZM1.32 on Odroid.

memeka · Post by **memeka** » Sat Feb 16, 2019 5:22 am

You should try installing the default ffmpeg packages from Ubuntu, not the ones from HK repository

pat2 · Post by **pat2** » Sat Feb 16, 2019 9:01 pm

I did. I un-installed the previous ffmpeg (it was from odroid repo since the reinstall was from odroid repo).

The I canceled the odroid repo and updated the repo list.
Then I installed the new one from ubuntu repo. I checked, during install, I was installing from Ubuntu repo.

Then installed ZM. For the last ZM version, ZM still continues to do not work for FFMPEG stream...

pat2 · Post by **pat2** » Wed Feb 20, 2019 8:24 pm

Hi Mad,

did you have chanche to understand why on Hardkernel Ubuntu images ZM is not working for ffmpeg streams?

Probably I already told you: I tried Odroid XU4 with an Armbian 18.04 image, https://www.armbian.com/odroid-xu4/ , the desktop one.
FFMpeg streams are working with ZM. There are 2 little issues for ZM on Armbian probably due to little bugs in ZM, but ffmpeg streams are working fine in ZM.

So the issue is something specific to HK images (16.04 and 18.04) and ZM higher versions (>1.29).

thanks regards

mad_ady · Post by **mad_ady** » Wed Feb 20, 2019 8:54 pm

No, sorry - I didn't have time to play with it yet.
One thing is ZoneMinder isn't using the ffmpeg binary directly and is probably using the libraries.

pat2 · Post by **pat2** » Thu Feb 21, 2019 12:39 am

ok, only my curiosity. if you, odroid expert and ZM user, not able to understand, definitively not possible for me.

ZM is using ffmpeg binary: there is in Option/Images table a field named PATH_FFMPEG telling ZM where the ffmpeg binary is (normally /usr/bin/ffmpeg).
I think the issue could be related to other libraries used by ffmpeg.
Anyway thanks for everything.

Michele

mad_ady · Post by **mad_ady** » Thu Feb 21, 2019 1:35 am

I'm not actually a ZM user. I've played with it once though.

Hardly an expert.
Can you try on a working system to run ps -ef | grep ffmpeg while streaming a ffmpeg stream? For me I got nothing, but it may be due to errors causing ffmpeg to quit.

I haven't given up yet, just busy

pat2 · Post by **pat2** » Thu Feb 21, 2019 4:32 pm

hi Mad,

I thought differently. Sure you were a ZM user!! Excuse my mistake! In this case pls take in consideration that ZM is a difficult tool to configure and make it working. Pls, don't spend too much tine...

Anyway I tried

Code: Select all

ps -ef | grep ffmpeg

on the 4 setup I have ZM.

The results are:

1 - on Radxa Rock/Ubuntu 14.04/ZM 1.30.4:
rock 16801 16790 0 08:02 pts/1 00:00:00 grep --color=auto ffmpeg
rock 16871 16790 0 08:03 pts/1 00:00:00 grep --color=auto ffmpeg (while ZM viewing FFMPEG stream)

2 - on Odroid XU4 n.1 / Ubuntu 18.04 HK image/ZM 1.32.3: with this setup FFMPEG not working on ZM!
odroid 29057 29047 0 07:11 pts/0 00:00:00 grep --color=auto ffmpeg

3 - on Odroid XU4 n.2 / Ubuntu 18.04 Armbian image/ZM 1.32.3:
odroid 7809 7730 0 07:09 pts/0 00:00:00 grep --color=auto ffmpeg
odroid 7819 7730 0 07:10 pts/0 00:00:00 grep --color=auto ffmpeg (while ZM viewing FFMPEG stream)

4 - on my PC Intel core 5 / Ubuntu 18.04 on VMware/ZM 1.32.3 :
michele 3141 2262 0 23:24 pts/0 00:00:00 grep --color=auto ffmpeg
michele 3859 2262 0 23:26 pts/0 00:00:00 grep --color=auto ffmpeg (while ZM viewing FFMPEG stream)

mad_ady · Post by **mad_ady** » Thu Feb 21, 2019 5:05 pm

Ok, so no ffmpeg process... I'll try some things hopefully today...
Edit: Sorry, no time today

Can you try the same on your end? You shouldn't need to downgrade ffmpeg.

mad_ady · Post by **mad_ady** » Tue Feb 26, 2019 12:02 am

Tried something else - I made a wrapper for the ffmpeg binary and added some logging to syslog to capture what parameters it tries to call. Unfortunately, zoneminder doesn't call ffmpeg directly, and uses the libraries to do it's work, so it's harder to inject that option.

One more thing I can think of is removing the firmware files for the decoder/encoder so that (hopefully) the /dev/video* nodes won't be created anymore. Or disabling some nodes in the dtb (but I couldn't find the relevant ones)...

Code: Select all

root@odroid:/usr/bin# mv /lib/firmware/s5p*.fw /root/
root@odroid:/usr/bin# reboot

Update: nope, the /dev/video* nodes still get created, but ffmpeg can't use them and doesn't know how to fall back to software decoding:

That's ok, Mad.

Zoneminder is an hard beast!

And since the support is based on volunteers it cannot be asked them too much. I will use the 18.04 Armbian distro on which ZM 1.32 is working except 2 issues that according to me are bugs in zoneminder 1.32. If lucky they will fix.
Or the 16.09 Hardkernel distro with ZM 1.29 that is fully working.
For who interested the installation procedure is in a post I wrote previously.

Since I'm not an expert I asked you support.

Thanks a lot: you are very kind and in general the forum is an effective forum in which it could be found support.

Thanks Michele

Hmm, a challenge is still a challenge...

I deleted the nodes in /dev/video* but ffmpeg still tries to use h264_v4l2m2m:

This wiki page confirms my suspicions that ffmpeg libraries are used: https://wiki.zoneminder.com/Ffmpeg

Now, why doesn't FFMPEG_INPUT_OPTIONS work? I had a look in the sources and the FFMPEG_OUTPUT_OPTIONS line is passed to "zmvideo.pl - ZoneMinder Video Creation Script", and in the generateEvent function which calls command-line ffmpeg to do a recording in case motion is detected.
So, it doesn't help this case.

Now - what options are left? It can't be fixed from zoneminder (unless you dig in the ffmpeg library code), so it should be fixable from ffmpeg. Sadly, this requires recompiling ffmpeg...

I'll give it a go and see how it goes...

mad_ady · Post by **mad_ady** » Wed Feb 27, 2019 6:00 pm

Success!

I've recompiled ffmpeg with --disable-v4l2_m2m and installed it and now zoneminder works correctly (with software decoding/encoding).

TL;DR version:

You can get the precompiled debs from here: https://oph.mdrjr.net/madady/xu4/deb/ff ... t-v4l2m2m/. They are tested with Ubuntu 18.04

You can install them with:

Code: Select all

# dpkg -i ffmpeg_3.4.4-0ubuntu0.18.04.1_armhf.deb libavcodec57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavdevice57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavfilter6_3.4.4-0ubuntu0.18.04.1_armhf.deb libavformat57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavresample3_3.4.4-0ubuntu0.18.04.1_armhf.deb libavutil55_3.4.4-0ubuntu0.18.04.1_armhf.deb libpostproc54_3.4.4-0ubuntu0.18.04.1_armhf.deb libswresample2_3.4.4-0ubuntu0.18.04.1_armhf.deb libswscale4_3.4.4-0ubuntu0.18.04.1_armhf.deb

Once you restart zoneminder, it should work.

The longer version:
You can compile your own ffmpeg build (you shouldn't trust some unsigned packages on the internet anyway):

Code: Select all

# sudo apt-get install build-essential fakeroot devscripts libchromaprint-dev librubberband-dev libjs-bootstrap
# sudo apt-get build-dep ffmpeg
# sudo apt-get source ffmpeg
# cd ffmpeg-3.4.4/
# vi debian/rules
### add --disable-v4l2_m2m under CONFIG_extra = section
# DEB_BUILD_OPTIONS="nocheck" debuild -b -uc -us
# cd ..
# dpkg -i ffmpeg_3.4.4-0ubuntu0.18.04.1_armhf.deb libavcodec57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavdevice57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavfilter6_3.4.4-0ubuntu0.18.04.1_armhf.deb libavformat57_3.4.4-0ubuntu0.18.04.1_armhf.deb libavresample3_3.4.4-0ubuntu0.18.04.1_armhf.deb libavutil55_3.4.4-0ubuntu0.18.04.1_armhf.deb libpostproc54_3.4.4-0ubuntu0.18.04.1_armhf.deb libswresample2_3.4.4-0ubuntu0.18.04.1_armhf.deb libswscale4_3.4.4-0ubuntu0.18.04.1_armhf.deb

You should polish up this guide and send it to @RobRoy and have it published in the magazine. Maybe add some tips for ZoneMinder usage as well/external clients. The interface is polished a bit better than the last time I saw it.

Post by **odroid** » Wed Feb 27, 2019 6:50 pm

Finally, you made it.

I'm also waiting for an article for easier setup because I'm building a tiny cabin on my small weekend farm land.

There are some wild pigs and foreigners steal my important vegetables and fruits.
So I have to prepare a couple of smart cameras as well as loud siren system with XU4/HC2 in a few months.

memeka · Post by **memeka** » Wed Feb 27, 2019 7:14 pm

@odroid - after setting up zoneminrr you can have a xu4 checking the rtsp stream and let you know when a human or when pigs come to your crops
https://magazine.odroid.com/article/obj ... gstreamer/

mad_ady · Post by **mad_ady** » Wed Feb 27, 2019 7:21 pm

Well, zoneminder can do motion detection and alerting by itself. Too bad I had to turn off hardware decoding

memeka · Post by **memeka** » Wed Feb 27, 2019 7:29 pm

Motion detection but not recognition of the object moving

Post by **odroid** » Wed Feb 27, 2019 7:38 pm

I just want to have simple motion detection, video storage(or streaming) and a very loud siren speakers.
Artificial intelligence for wild boar recognition seems to be too much.
I'm not sure if OpenCV with artificial intelligence can distinguish between pig face and chicken hips.

mad_ady · Post by **mad_ady** » Wed Feb 27, 2019 7:39 pm

That is true, indeed. But if you're after object recognition, you can probably skip zoneminder and do it as you suggest, or have your script trigger zoneminder to start recording.

Note - the ffmpeg downgrade above should be done only if zoneminder can't work with your camera with hardware decoding. I expect streams from better cameras to work with hardware decoding. A lot of cheaper cameras are cutting corners.

pat2 · Post by **pat2** » Thu Feb 28, 2019 1:43 am

hahahhahahaha

nice conversation.

odroid, to install ZM 1.29 on 16.04 Hardkernel image please follow exactly instruction of

viewtopic.php?f=95&t=33745#p245965

ZM 1.29 is fully working in this case.

In my next post i will add other info like: howto record on motion detection, how to record on an HDD or a network HDD, how to expose in WAN (if you need), how to access it only through userid/pwd, how to encrypt all, ....

At home and in the hospital i installed ZM it's used exactly to catch images of foreigners trying to take important things ....hahhahahahahahah

If the cameras have the possibility to move: you could configure too scripts to give them PTZ commands. There are already available scripts for famous camera. It's possible to build scripts dedicated to a specific camera if not yet available in the tool.

ZM is a little bit hard tool to install and configure, but really strong and full of functionalities.

mad_ady · Post by **mad_ady** » Thu Feb 28, 2019 3:23 am

@pat2: when you look into it, try several recording methods - saving as jpeg frames, software encoding to h264 - both in terms of disk usage and load/heat.

You wouldn't want your xu4 to overheat and shut down while an army of ninjas invades your house and triggers all your cameras.

pat2 · Post by **pat2** » Thu Feb 28, 2019 3:41 am

hahahhahah

with the odroid xu4 i'm sure! it's enough my old Radxa Pro, imagine with Odorid!
More seriously, I did! In ZM there is load indicator. With Odroid -same setup- it decreases 1/4 or 1/5!!

Odroid XU4 is really a strong board!

pat2 · Post by **pat2** » Thu Feb 28, 2019 8:54 am

UPDATE!

I found an hardkernel 14.04 image. it's valid for XU4 too. Even if marked XU3!

I installed ZM 1.30.4. The procedure is a little bit different from the previosly posted one. I will post it!
It works fully! The same setup I have with Radxa! I could dismiss my Radxa! Great!

EDIT: trying to mount SSD on USB3 with 14.04 HK. I'm able to do on whatever other image (16,04 HK, 18.04HK and other).
For 14.04 HK the system doesn't see the SSD when connected. I tried

ls -l /dev/disk/by-uuid/*
sudo blkid

so i'm not able to insert in /etc/fstab something like:

UUID=BE28A67028A626FD /home/odroid/Documents/STORAGE auto nosuid,nodev,nofail 0 0

Any reccomendation? Is it an issue of 14.04 with SSD or with USB3?
thanks
