ZoneMinder Forums

Okie dokie-

I've been a long time happy zoneminder user for quite some time now. I've decided to update the box, but keep my capture card.

I've done an Ubuntu Server 10.10 install with apt-get install zoneminder. Thus far, the only substantial change that I've made is adding www-data to the "video" group.

Here's the biggest problem.
When I go with
/etc/modprobe.d/options.conf
#options bttv gbuffers=16 card=77,77,77,77

Any kind of video I get is either interlaced (no matter the resolution) or is only yellow.

If I do go with having
/etc/modprobe.d/options.conf
options bttv gbuffers=16 card=77,77,77,77

I get *no* video in either v4l or v4l2.

I'm stumped. I haven't had this much trouble with ZM or v4l in the past; it's always worked right out of the box with very little hassle.

In addition, there is an error that keeps cropping up with any of the videoX's:
Can't chmod /dev/video0 to 20666: Operation not permitted

I'm modifying the startup script for ZM to chmod 777 /dev/video*

Ultimately, I'd like to get this working again with the newer (and faster) system.

Any shortcuts and pointers as to where I should prod would be great.

=========

I just needed some sleep. Here's the working result:

In:
/etc/init.d/zoneminder
In the Start function, these are the first few lines:
sleep 15
chmod 777 /dev/video*
zmfix -a


In:
/etc/sysctl.conf

kernel.shmmax = 268435456
kernel.shmall = 268435456

I removed the /etc/modprobe.d/options.conf file. It wasnt needed.

Currently, with only 6 cam's the frame rate is 1.5 with disabling V4L_MULTI_BUFFER. Enabling it, of course, shows many interlace issues, but the frame rate jumps to 15fps which is what I'm after. To completely solve this, I'm after a higher frame rate- any options?

Okay,

update. I'm not able to get more than 1.5 fps for 6 camera's that are on this card. I've load balanced them out across three of the encoders (video0/video1/video2). I also cannot have more than one zone, otherwise capture stops for the cameras on that one chip. The resolution is 320x240, and there is still interlacing with other video channels (sometimes the picture from it, other times blue). Finally, video channels on the same channel seem to randomly go dark.

Practical question. Since I'm no longer getting anywhere near the desired frame rate, should I just purchase two PV-149's?

did you give the LiveCD a shot? I think it uses Arch.

extra frame captures to "settle" the capture image?

pretty much, I dunno but I have similar issues PV-149 but the one I have supposedly does 8 cameras. When I have 2 cameras on a channel the frame rates goes in half.

I might dittel with the memory settings shxxxx and try mmap if I can figure out to to turn it on.

Good Luck,
Pat Jr.

mate i think its a 10.10 problem
i setup a new box with 10.10 and also tried 10.04
but bugger me i have 4 cards and all of them are interlaced
then reading this thread i wonder

anyway how did you go

I'm starting to wonder if it is 10.10 as well with this new info. I've messed with the memory settings, and frame rate adjustments.

It's still interlacing randomly. I'm going to disable some stuff to try to rule out IRQ.

I have a PV-155 attached to 9 cameras.

With V4L_MULTI_BUFFER off and CAPTURES_PER_FRAME set to 2, I get ~2.5 fps on cameras that are sharing a capture chip with another camera and ~1.6fps on cameras sharing a capture chip with 2 other cameras. This is without the random interlacing issue.

The issue you are having sounds like you don't have your camera's evenly distributed across capture chips and have 3 cameras on one capture chip and 3 cameras on another capture chip.

for example, with the following setup you should get:

camera1 -> video0 ch0 = 2.5 fps
camera2 -> video0 ch1 = 2.5 fps
camera3 -> video1 ch0 = 2.5 fps
camera4 -> video1 ch0 = 2.5 fps
camera5 -> video2 ch0 = 30 fps
camera6 -> video3 ch0 = 30 fps

another alternative setup would be:

camera1 -> video0 ch0 = 1.6 fps
camera2 -> video0 ch1 = 1.6 fps
camera3 -> video0 ch2 = 1.6 fps
camera4 -> video1 ch0 = 30 fps
camera5 -> video2 ch0 = 30 fps
camera6 -> video3 ch0 = 30 fps

yea i tried that
i followed the wiki to the t
so i installed server 9.10 and used the identical wiki howto
and bam to works now

I've balanced it out as well. Each chip is supporting two camera's.

I'll give ubuntu 9.10 a shot in the next day or so.

I've learned about a bunch of changes that have gone into 10.10 from new applications that manage security on the platform that weren't there in the 9 series. Before I reinstall, I'm going to try disabling all of them

Then it certainly sounds like an issue with Ubuntu 10.10.

Hopefully this is an Ubuntu thing and not a mainline Linux issue that will eventually creep into other distributions.

Okay,

downgraded to 9.10. Followed the wiki here: http://www.zoneminder.com/wiki/index.ph ... 10_Desktop

Yeah- zoneminder doesnt work anymore. at all.

here's some additional info:

sysctl -p
kernel.shmall = 1073741824
kernel.shmmax = 1073741824

I know the "cant get shared memory" is a shared memory issue, but I've allocated 1GB!

Currently running 1.24.1 from apt-get install zoneminder

Check the value of the Shm_key in the options, if it's not = 7a6d0001 try changing it to this value (saw this in an unrelated post and fix, it did clear up the memory issue in that case).

Thanks!

A combination of that and adding irqpoll to grub took care of that.

All image streams are coming in *faster* than what I've had before on the previous hardware.

One last bit of goofyness:

they're all reporting random and odd fps, like -3744131936485390524185011246081821665100925998966105412907634927417968350828279424352256 fps

Okay- so after many months of happy run time, and reboots as well, it has finally decided to stop working again. As I recalled from my note taking thread... it had to do with the shared memory key. I tried changing the values around, but it doesnt work at all.

The key is currently set to: 0x7a6d0001

If all you are getting is complaints from zmwatch that doesn't necessary mean disaster. If you type 'ipcs -m' do you see the shared memory segments listed? Do the permissions look ok?

Yeah- the owner is www-data for the processes and the memory space. I dont know why it's 700


When I let it run, I'll get one frame, the screen will go black, and then maybe one frame comes back 15 or so seconds later, goes black, rinse repeat.
