i cannot remember the exact model, but i have bought one of those
philips webcams too for an installation and since there was only one
single colour-space supported i have written the conversion-routines
from yuv420p (i think that was it) to YUV422/RGB(A)/grey (the last of
which was very easy ;-)). it should be in the CVS-version of Gem
(GemPixUtil.cpp: fromYV12(char*yuvdata); YV12 is the FOURCC-name of yuv420p)
