I have found another piece of software which already supports ov519
cams called "showvideo" and available at
http://www.wlug.org.nz/archive/software/ov51x/ With this, grabbing
moving pictures at 640x480 will make my 900MHz Athlon CPU run at 98%
load. ;)
But at least it is working. showvideo used libjpeg to decode the raw
data from the cam, then imlib to display it.
Ciao
