Update: http://www.zdez.org/fcnok-1.1a.tgz has just the flashcam and flashcam.c files. Setting the right resolution prevents the 4x magnification (so it looks normal in the small window), plus some optimization and ignoring EIO, which works well. (the 640x480 original will be reduced to 160x120 but have a much slower frame rate).

Note: I had to load things as root - I don't think I have all the permissions right, but I need to use/work the install script to change the perms right
