Is "Motion detection" sw linked to liberaries?

Hello,
How is Motion Detection software interpreted, and who is responsible for the interpretation operation?
Is motion.conf linked to a specific libraries?

I'd be grateful If I get some help.
Thanks in advanced.

Motion detection is done however the developers of the motion detection software you are using designed it to work. motion.conf is presumably a text configuration file, so it not linked to anything, as it's not code. If you want to study the motion code, then you should get the source from their project page and read it. You can also do something like "ldd /usr/bin/motion" and that will technically show you what library options are linked to it, but that's hardly the way to start learning about motion detection.

I just want to have an overview .. I want answer for my questions that in my mind.
e.g.

Quote:

videodevice /dev/video0

Quote:

input 8

videodevice /dev/video0 #How it know that mean listen to get an input for device video0?
input 8 #How it know that means, the input is USB webcam ?
Who is translate that script file (motion.conf)? Who understand it to execute it?

The motion detection software interprets that file (it is not a script, it is a configuration file). It knows how to interpret that file, because the developers (that designed both, the software and the configuration file) have written it in that way.

Code:

$ sudo apt-get install motion

I installed it usinf that command.

I found motion.conf +4 thread.conf (case I am going to control more than 1 webcam) in /etc/motion
I don't know where is the source of the software, Do you have where find it to understand it parallel to the configuration file?

You can install the source in your current directory with

Code:

apt-get source motion

Please be aware that you can find this stuff out for yourself very very easily by just googling for it. You have just picked on one arbitrary bit of software, it is not a standard, it is just some developers writing a bunch of code as they see fit. If you think that a configuration file is some magical standard, I really think you need to take a step back from it and learn more of the basics.
