storing defaults ?

ive got ZM working with a labtec ( logitech) camera.

Problems
1. I need to chmod 777 /dev/video0 before i get pictures

2. If i go into the console to rotate the image it goes black ( ie the same results before i change the permissions on /dev/video0

ive tried changing the image dimensions , but havent got the picture back .

Where do i delete any changes so that I can get back to a working system ?
What do i need to save as a default config so when it goes t***s up I can recover the situation

What Distro and Release are you using?
What user owns the processes?

Ive got this in a right mess.
Resetting stuff to the defaults ( as I remember them ) hasnt got an image back and rebooting the machine doesnt do it

Okay so what user owns the processes?
It should be your web user.

so ive tried unmerging and then re-emerging zoneminder ( keeping the original /etc/zm.conf with the database settings )
and i still have no picture.

I cant shange any of the camera setting ( console->webcam->settings). When i enter a number in there it is blanked out - so where is this information stored , as the web process ( apache) cant write to the file ( well I think thats the problem )

ive manually added user apache to the video group and my picture has come back !
Must be a gentoo thing - theres a similar problem and solution with gentoo on this forum.

The problem now is that if i rotate to L or R then then the image disappears.

other manipulations ( invert/flip) are OK .

You will probably if you search your logs find an attribute error which is the result of rotating your image as documented in the README:

Orientation – If your camera is mounted upside down or at right angles you can use this field to specify a rotation that is applied to the image as it is captured. This incurs an additional processing overhead so if possible it is better to mount your camera the right way round if you can. If you choose one of the rotation options remember to switch the height and width fields so that they apply, e.g. if your camera captures at 352x288 and you choose ‘Rotate Right’ here then set the height to be 352 and width to be 288. You can also choose to ‘flip’ the image if your camera provides mirrored input.

thanks for the help - ive added what i had to do to the wiki
