Hi all

Zoneminder 1.22.1
Linux FC4 i386

I get the following error in my zmdc.log when i change my Axis network cams to resolutions 320x240 from any other, and yes the camera have the same resolution as ZoneMinder, and there are no errors in messages.

Code: Select all

Does any one else get this error.

And btw if i change the resolution to any higher it works.

Could it be possible that when you reduced the image size that the zones are still trying to analize a larger image size?

Can you do

Code: Select all

addr2line -e /usr/libexec/zm/bin/zmc 0x806a681

and post the result. It sort of looks to me like it's crashing in a debug statement.

Hi Phil

I ran the command :

addr2line -e /usr/libexec/zm/bin/zmc 0x806a681
and post the result. It sort of looks to me like it's crashing in a debug statement.

And the result is :

Code: Select all

??:0

And ZoneMinder debug is off.

I can reproduse this error on my test server by getting ZM to work with the cam in res. 640x480, and change the res. in the cam to 320x240 and then change the res. in zm to 320x240 and there is the error.

Post by **zoneminder** » Wed May 03, 2006 10:17 pm

I will try and see if I can reproduce this. Did you compile your binaries without -g by the way? If so perhaps you could compile them with it and run the addr2line command on a compiled binary. You don't need to install it at all, just compile, run the command and then delete!

It might help me pinpoint where to look and whether I find the same issue as you.

Hi Phil

This is my configure command for my custemized rpm.

Code: Select all

./configure ZM_DB_USER=%{zm_db_user} ZM_DB_PASS=%{zm_db_user_pass} --prefix=%{zm_home} --sysconfdir=%{zm_config} --with-libarch=%{zm_lib} --with-mysql=%{mysql} --with-ffmpeg=%{ffmpeg} --with-webdir=%{zm_webdir} --with-cgidir=%{zm_cgibin} --with-webuser=%{zmuid} --with-webgroup=%{zmgid} --enable-debug=yes --enable-crashtrace=yes

No not -g but i can do that tommorow, now it is time to sleep.

Post by **zoneminder** » Wed May 03, 2006 10:23 pm

Unless you turned it off with CXXFLAGS or CFLAGS I would expect -g to have been used. I will try and reproduce the issue tomorrow anyway.

Hi Phil

This is my make part :

Code: Select all

make

This is my make install part :

Code: Select all

make DESTDIR=$RPM_BUILD_ROOT install

Hope this can help you to reproduce the problem.

It would seem to me that there is a problem with the low resolutions like 320x240 and below, iam not 100% sure on this thou, but i cant get zm 1.22.1 to work with these low resolutions.

Post by **zoneminder** » Thu May 04, 2006 1:37 pm

I have identified a couple of issues with Zones, specifically, though not excleusively, to do with resizing of monitors. I suspect this may be the problem in your case. I am testing some fixes and will post a patch a bit later.

voronwe · Post by **voronwe** » Thu May 04, 2006 2:31 pm

Hi Phil

That sounds good, that a possible bug have been found and identified, then we can get that out of the way.

No hurry from my part, i have installed zm v. 1.21.4 at the custemers site, since it is a live system, but i will be glad to test the patch on my test server when it is ready.

voronwe · Post by **voronwe** » Thu May 04, 2006 2:33 pm

Ohh and btw Cordel

Yes that could be the problem, but then again iam not that much of a programmer so the backtrace dont tell me anything.

Post by **zoneminder** » Thu May 04, 2006 3:18 pm

Patch attached if anyone is feeling brave. Also available from http://www.zoneminder.com/downloads/zm-1.22.1-p1.txt

After applying the patch below and re-installing, I'm still seeing the following about every 10 or 15 minutes.

This looks like an assert failed. There _should_ not be any reason for these any more. Can you do the addr2line thing on the addresses in the backtrace?
