Once I found an article titled 'Video with Linux' that was published in the German Magazine FreeX 1/2004. After reading it several times I brought a Philips webcam and started with the basic configuration of my Debian GNU/Linux system (custom kernel with USB support, v4l with additional tools etc.).
Among other things there was a program called Motion mentioned in the article above. I found out that a quit new version of that program was already in the current Debian Distribution. So as soon as I had a working video device I installed it. Motion is a nice piece of software for detecting motion in video streams that is developed by volunteers within the Linux community. From the projects website and mailing list I received a lot of valuable information. Example: Despite of providing the recommended version of Ffmpeg for Debian my Motion was unable to encode mpeg-movies on the fly. But this seemed to be a regular problem to include support for Ffmpeg into Motion, since I found several questions with relation to this problem on the motion mailing list and with them the solution.
