Hi,

I read the French blog from the main author, looks to me it's a script
trying to detect which chipset the camera is using, and then installing
the right driver.
But for uvcvideo it's broken, since uvc shifted from svn to mercurial
and the compilation method changed accordingly.
uvcvideo is in the kernel starting with 2.6.26, gspca in 2.6.27 and
above, and all are available through module-assistant, so the script is
just to save the user the hassle of running a search with the usb ID,
and installing the driver.
>From the author blog I could understand that several drivers aren't
included in easycam, some are but installation process is broken, and
the author doesn't have much time to look into this (he is preparing a
challenging exam, French "concours", we are very fond of those...).

Finally it's intended for Ubuntu users, I didn't look into the code, the
main author says it's written in python and Glade provides the GUI.

So to answer your question, it seems to be more than a gui way to
replace m-a, the webcam detection module seems to be the important point
in easycam, on top of which is the collection of driver installation
routines.

Hope it helps.

Yes, it is much more than I could understand from the main web pages. I knew the steps it asked you to follow, but did not know what was going on under the hood.

A friends is asking me if he should try this out. I wanted to see how it worked in Debian first. I did not find the package in Debian so that naturally raised a flag. I actually wanted to see what it did so that I can help my friend undo whatever it does on his Ubuntu machine if it does not work out for him.

Thanks for your comments.
