ic0n_: I rolled back to the Oct 2016 build I have... It's the nph-zms servers streaming to the browser which are consumer way more cpu...

In Oct build, they use ~1.3% of cpu

in the one I built yesterday, they were using more than 4%

Bhaal: interesting. are you using mpeg streaming?

mastertheknife: No, just regular mjpeg

waiting and waiting and waiting for rexd666 to get the h264 -> browser direct working... And stopping ZM from decoding to jpeg when doing record only...

mastertheknife: What kind of cpu temp increase have you noticed with ZM running on a Pi?

from shit to hot shit?

haha

temp=67.5'C <--- Temp with IR board off during the day ... Last time I checked at night it was sitting at 83.3'C ...

At 85 it starts slowing down the CPU or may shut it down completely, I cannot remember...

anyway .. bbl

meeting to go to

Ichanged the data type for the AutoTimeOut field in the Monitors Table from DEC(5,2) TO DEC(6,2) , THEN all my recorded events disappeared. Is this related, or did something else happen

Also, no events are recorded any more for this zone

I think I found the issue, it was a faulty delete event filter Thanks for listening.

Bhaal: I haven't installed ZM on a Pi. I am optimizing some of the motion detection code for ARM's Neon instruction set

Bhaal: So far its been fun, managed to get 2.5x - 3.0x speedups yesterday, it seems the ARM loves parallelism and prefetching

mastertheknife: Ahhhh

Well seems I will have to give it a test

bhaal I can't image what might have change to increase cpu load of zms.

I can try it again

just to confirm

Just as an example:

18991 www-data 20 0 577352 191348 184164 S 1.7 4.9 0:57.98 nph-zms

18989 www-data 20 0 577352 193340 184116 S 1.3 4.9 0:43.28 nph-zms

18990 www-data 20 0 577352 193360 184132 S 1.3 4.9 0:44.92 nph-zms

18995 www-data 20 0 577352 193356 184120 R 1.3 4.9 0:43.47 nph-zms

maybe if one build was using jpeg-turbo and the other wasn't....

Woooo thunder

ic0n_: Ok, so load is *slightly* higher before I start montage

but not significant and to soon after start up

ic0n_: Confirmed

21531 www-data 20 0 572912 198504 195416 S 4.7 5.0 0:00.96 nph-zms

21538 www-data 20 0 572912 192068 186988 R 4.7 4.9 0:01.08 nph-zms

21527 www-data 20 0 572912 200444 195292 S 4.3 5.1 0:01.00 nph-zms

21532 www-data 20 0 572912 198820 195712 S 4.3 5.0 0:01.04 nph-zms

ic0n_: Is that a quick one line change to un-jpeg-turbo?

it comes down to build time detection...

Ok, well in that case, nothing has changed on the server

Hmm... I wonder if it is doing scaling now... unnnessessarily.

You may notice that there are now option to use a fixed width/height on montage... maybe I screwed something up in the zms url...

All mine are scaled to 37%

I don't use the normal montage ...

you might compare the url to zms in now verse oct 22

Hrm... ok

ic0n_: Version I compiled last night: /zm/cgi-bin/nph-zms?0=mode%3Djpeg&1=scale%3D37&2=maxfps%3D5&monitor=9

And Oct 22 compile: /zm/cgi-bin/nph-zms?mode=jpeg&scale=37&maxfps=5&monitor=9

uh yeah... you said you are using your own customised montage? I changed how parameters are passed when generating the img url... so I think that is screwing up your zms

I will pastebin the code

It's just a cut down version of the normal montage I have removed all the cruft

(no offence)

ic0n_: https://pastebin.com/eAXj0PuE

yeah so getStreamHTML now takes an array of options. So you are probably passing "scale=$scale" or "scale=37" but now you want to pass array('scale'=>37)

ok.. so getStreamSrc, I changed it to take a hash, not an array of string containing =

so $streamSrc = $monitor->getStreamSrc( array( "mode=jpeg", "scale=".$monitor->MontageScale, "maxfps=".ZM_WEB_VIDEO_MAXFPS ) );

becomes $streamSrc = $monitor->getStreamSRc( array( 'mode'=>'jpeg','scale'=>$monitor->MontageScale, 'maxfps'=>ZM_WEB_VIDEO_MAXFPS ));

Ok, will give thta a shot

ic0n_: Yep, that's fixed the load issue, yay!

interesting

ic0n_: I think a setting for each monitor to set a scale would be good... I do it manually when I create my monitors...

there is one...

not used much though.

there is a lot of work to do with scaling. I'm going to implement it on zone editing first.

Guys, how to fix this "Socket does not exist" error?

I might have set wrong paths somewhere, but I don’t know where to start.

google, we are so tired of answering that question.

All dependencies on the system are there since I’ve had the whole thing already running once.

I tried but alright. Try some more.

does the zm api work with php 5.6? or is it 5.4 only?

yes

to which question?

API requires php >= 5.4

ok

ic0n_: I couldn't find a scale for the montage which was able to be set individually per camera...

no it doesn't use it, but there is a scale setting on each monitor

ic0n_: It was useful when I had 640x480 mjpeg cameras in the mix...

ic0n_: yeah a "Default Scale" but it doesn't allow me to be specific...

I await your PR

Hahaha

I have to start from scratch with git I think before I go ahead with more PRs

hmmm ok, so i have php 5.6 and php7 installed, and OPT_USE_API is enabled, but I can't seem to access it at all

So the UK is definitely brexiting... wow :(

So will that mean Ireland will then Brexit from the UK?

Bhaal my next cruft in montage will be the ability to show the zones on it.

Got it. Permission problem.

Do one need to take care of the systemd files somehow specially?

ic0n_: I'd find that more useful as a switch on a per monitor basis, not so much in the montage, but maybe useful

knnniggett: csrf doesn't seem to block my csrf test

might be an issue with how I've merged it..

ic0n_: are you saying it doesn't block it when it should?

On the one hand you have https://github.com/ZoneMinder/ZoneMinder/blob/m..., but my temporary file in /var/run/zm isn’t created.

ic0n_: If I am happy with having ZM on the Pi's then I might be more likely to do motion detection ... Then the thing I'd like to see in the console is "Motion Events"

yup

Mar 29 16:05:10 titan zmpkg[12955]: FAT [Can't create missing temporary directory '/var/run/zm': Permission denied]

syrex: you have to reload the tmpfiles.d service. See the systemd docs. Describing your environment and how you are attempting to install zoneminder would be very helpful here.

knnniggett: You can use this url. It will insert a user into your zm

ic0n_: By design of the latest commit, the CSRF check will not run when processing logins

I’m on ArchLinux and building from current master. It works now, but seems to require manual intervention on the one or other occasion. Will check out how to reload the temporary files.

ok, looks like a merge problem as my tree is different than master.

syrex: that's because you haven't reloaded the tmpfiles.d service. Most packaging scripts take care of that for you, but if you are building from-source then you've got to do it manually (or just reboot).

knnniggett: okay, I'm good with the csrf. DO you wore people to test it or shall I just merge?

What do I need to test?

ic0n_: let me post another message in that pr to see if we can get a response/blessing from asker or mmn (?)

Reboot does not help and there is no zoneminder*.* in /usr/lib/tmpfiles.d/. Do I have to put it in there manually or have I missed something in the cmake configuratino?

bhaal: update, turn on csrf protection in options. then go to the url I posted above and see if you have a new user named attacker1

What is csrf?

CMakeLists.txt says: “Do not install the misc files by default” and there are no installation instructions for system files. Are there intended to be placed manually if building from source?

so if you have a tab open logged in to zm... and in another tab you browse to a malicious site... the malicious site can post to zm as your authenticated user

Really??? Why have I not heard of this...

syrex: Yes, you have to manually put all the config and init files into their proper place when you build from-source

Alright, that’s what I needed to know. Thanks, knnniggett.

ic0n_: What browsers?

all of them

:(

syrex: So every distro is different when it comes to where to put all the config & init files. Systemd helped standardize a lot of that, but there are still differences. If if it not obvious where something should go, then the best place to look would be in an Archlinux forum. They tend to have really good (better than most) zoneminder related information.

ic0n_: I didn't turn on the CSRF thing, I went to that URL which then redirected and went to a login thing.. But no new users on my server...

hmm.... you say you didn't turn it on?

correct

Got it. Seems good.
