switchfilter still not working in 3.2.4.snap2

Question

Hello Kenneth

I tried 3.2.4.snap2 as you recommended but the problem still remains. With switchfilter on no one motion is detected.

 motion --version
motion: invalid option -- -
motion Version 3.2.4, Copyright 2000-2005 Jeroen Vreeken/Folkert van Heusden/Kenneth Lavrsen

usage:  motion [options]


Possible options:

-n              Run in non-daemon mode.
-s              Run in setup mode.
-c config       Full path and filename of config file.
-d              Debug mode.
-h              Show this screen.

Motion is configured using a config file only. If none is supplied,
it will read motion.conf from current directory, ~/.motion or /usr/local/etc.

Answer

use <VERBATIM> </VERBATIM> tags round text when you want to avoid TWiki formatting the text. And continue this topic instead of making a new

Can you post the entire motion.conf and the thread files? You can simply attach them to this topic. Use the link at the bottom of the topic.

It may be that the switchfilter detects certain types of Motion as a camera change. And I need to learn what this is. It may also be good to see some examples of motion detected when the filter is off.

I have added a comment box to make replies easier but you can also edit the page and add your follow up in front of the COMMENT tag.

Hello Kenneth

I put the config files as attachments. As you can see I used a value of threshold less than the default so that a movement of a person at 10 mt from the camera could be detected.

In order to test switchfilter I walked in front of the camera so the number of changed pixel was by far greater than threshold. I am sending the jpegs of the images of motions detected without switchfilter takens from two cameras (threads 1 e 2)

Your config files do not show anything that should prevent motion detection.

I have something to look at. I will try and find some time to play with the switchfilter and try to understand what it is it is supposed to do. The fix I just made was not related to the algoritm but the way the function was called which was very wrong. But I guess the feature will need some more fixing.

You should update your motion.conf and config files to match version 3.2.X.

It is very easy. Just open the control port with a normal browser and save the config files. Then Motion is smart enough to clean up the files. All the obsolete options are removed, the new are added with their default values, and the common values are moved from the thread files to motion.conf.

It is a good idea to save the original config files before you do this - in case there was a commented out value you want to return to or Motion dies during saving.

I will follow up when I know more about this bug.

Thanks Kenneth, I'll be here waiting any news.

Did you try the MotionRelease3x2x4snap3 that I released 08 Oct 2005?

It may have improved and maybe cured your problem.
