Hopefully someone can point me in the right direction as I am fairly new to linux
Background
Ubuntu 8.04 server 64bit edition
PCI-e DVR card with 8 chips - based on phillips SAA7130 chipset
this is the card I have:
http://www.camsecure.co.uk/PCIECapture.html

According to HCL the drivers for the card are installed:

video 0 to 7 are listed in the /dev directory

zmu output:

I currently can't get an image from either zoneminder or xawtv
output from xawtvis:

game over

I have read that there is a bttv.conf or an modprobe.conf file that probably needs modifying but I can't find either!

Some help would be really appreciated!

For Unbuntu, you need to create a configuration file (call it something like "saa7134") in the following folder:

/etc/modprobe.d/

FYI: The /etc/modprobe.conf file is depreciated, which is why you didn't see it.

The next step (the hard part) will be to populate the file with the right configuration info. It looks like this driver is configured similar to the bttv driver so the following may be helpful:
http://www.zoneminder.com/wiki/index.ph ... t8x8_Cards

You'll need to figure out the correct card type for your hardware. You may not have that info on your machine. I had to download the saa7134 driver here:
http://dl.bytesex.org/releases/video4linux/

and then open the file "CARDLIST.saa7134" found under the doc subfolder.
That lists all the available card types.

Thanks for your reply.

Yeah, I had a look at that - I think it's fairly out of date as it only lists 33 cards and the return from dmsg lists 117! - I tried dmsg and found that the card is listed as indervidual chips (ie 8 of them) plus all the possible card options:

What would happen if I inlcuded several options in the file, I was thinking of adding them all? ie:

options bttv card=1,1,1,1,1,1,1,1
options bttv card =2,2,2,2,2,2,2,2
etc, etc,

sorry t show my ignorance but why is this and what does it mean? Similar to hiding system files/folders in windows?

Posted: **Tue Sep 08, 2009 1:32 pm**

Hmmm.... my hunch is that adding all 117 options to your configuration file will not work. My guess is that either the first or the last set of options will be the one that takes effect, but I've never tried it myself. It's possible you could end up with a system that doesn't finish booting (or boots incredibly slow) so, unless you are up to a good challenge, you may want to avoid trying this.

Oh and about the "depreciated" comment....
When a certain way of configuring something in software becomes outdated, we call it "depreciated"... meaning that it's possible you could get your system to run using the old method, but at some point in the future only the new method will work. Consequently, one should typically start using the new method as soon as possible.

In your case, the "old" method is to place module options (for all modules on your system) into a single file called "modprobe.conf". Today some systems may have this file hanging around and some may not. It's possible you could get things working by placing your module options inside this file. However, the "new" way of doing things is to create a separate file for each module in the folder "modprobe.d". At some point, placing your options into the "modprobe.conf" file will no longer work.

I know.... that was the long answer to your question... sorry about that.

But back to addressing the real issue...
You are in what I would call interesting position (maybe I'm weird, but I find it kind of fun). You've got a card with a chipset known by Linux, but it doesn't look like anyone has posted instructions for the specific card you have (at least I did not see any). What I recommend you do is follow the method posted in this thread:
http://www.zoneminder.com/forums/viewtopic.php?t=5921

While the card in that thread is different than yours, the method for determining the card type should work for you.

The author shows how to go through all the card types w/o rebooting. Once you find a set of options that work for your card, to make it permanent, simply place the options into a text file in your modprobe.d folder as mentioned previously.

And lastly, let us know your results so that we all can benefit from your work.

Hope that helps, and I hope you enjoy your Linux experience(es).

one other thing if I used these commands with the appropriate vales:

rmmod saa7134 (remove current driver)
modprobe saa7134 card=n,n,n,n (Install new driver, n = cardtype)

and then listed dmsg, would this then list the new driver or just the orginal?

Thanks for your help

As changes to your system occur, new information is appended to your dmesg output.

Posted: **Fri Sep 11, 2009 4:44 pm**

Sucess! I found card=2,2,2,2,2,2,2,2 worked and also card=3,3,3,3,3,3,3,3 - can't decide which gives the best picture.

I also found that adding -v to the "rmmod saa7134" and "modprobe saa7134 card=n,n,n,n" line was useful to esnsure things were actually happening becuase:

knnniggett wrote:As changes to your system occur, new information is appended to your dmesg output.

Not accutally sure if they do when an option is specified in a config file in the /etc/modprobe.d direcetory. I foud if I removed this then there was less of a problem.

I think I will write this up with a pitcure of the card as a how to post?

Thanks for your help.

Just one other thing I realise that I need to install cambozola to allow streaming to IE. I have downloaded the tar.gz file but have no idea how what to do with it once extracted? I have installed the ant command but just get errors (will post these for you to see on monday), any suggestions in the meantime?

Posted: **Sat Sep 12, 2009 11:09 pm**

Glad you got your card working. I bet you are glad that your card was number 2 or 3 in the list rather than number 115.

IMO the easiest way to get Cambozola to work is to simply download the one from the Zoneminder Downloads section. After downloading simply uncompress and copy the cambozoola.jar file to your zm web root folder. Then it just magically works... no need to use ant.

Ok after many hours trying to get this card to work I threw in the towel and got Phil to SSH into my server to sort it! Here is a list of the CLI history for those that are interested. I have not had a chance to go through it myself yet, I would be grateful if someone has the time to interpret which are the important commands and what they do?

I've skimmed through Phil's command history a few times and here is my take on what was done:

- gather info about your video device with v4l-info
- Turn up zm debug
- Check that the Ubuntu deb package you used put everything in the right places with the right permissions
- Check zm log, apache log, and syslog for errors
- Edit/Read apache config file (my guess is to determine the proper user and group names ...e.g. www-data and www-data)
- Check /etc/modprobe.d/libsane for blacklisted bbtv module?
- Delete all existing zm events
- Create a new events folder, linked to the following disk /media/disk/cctv
- Change user and group ownership of your events folder to www-data:www-data
- (re)start zm, check log files for errors
- Done

Barrydocks, unless I overlooked something, to me it looks like the root cause of your problem was an incorrectly configured events folder. Based on what you told me privately and what I see in the history, it does not appear that any configuration files (zm, apache, or your driver modules) needed to be changed.

Perhaps we could get Phil to confirm or deny this.

hmmm...

I didn't think there was anything spectacular going on, I think I might hook up a spare HHD with a fresh Ubuntu install and try to replicate the steps (not sure when mind).

Thanks for your help.

PS how are you with SAMBA problems? have a look at:

If you feel you must share your zm events folder, I recommend setting the read only flag on your cctv samba share just to prevent any accidental deletions or modifications.

yes the thought had crossed my mind, I was a bit worried about preventing the zm filter I have set up from deleting events and ending up with a full HDD

ps have replyed to the other thread with even more questions

thanks for your time

I've just realised that if I limit the access to the CCTV folder via samba, it will no affect data being written to the folder by ZM as this is not governed by samba, right?

Posted: **Fri Oct 23, 2009 4:10 pm**

There are two layers of permissions we are dealing with here: file permissions and samba permissions.

The way your system is configured, Zoneminder records directly to /media/disk/cctv. It doesn't use samba to do this. Consequently, you can set your Samba permissions to anything you want, and it will not affect Zoneminder.

Out of curiosity sake, for what purpose do you want to remotely access your Zonemidner Events folder? Backups perhaps?
