Ok, I compiled webcamd with debug and additional printf's to catch the ioctl's coming down from Skype; I launched by hand (i.e. not via devd(8)) two webcamd in two windows: # ./webcamd -d ugen4.2 (for the built-in, gives /dev/video0) # ./webcamd -d ugen4.4 (for the external, gives /dev/video8) Then I launched skype and on its start only /dev/video0 is probed as I can see in the window for ugen4.2; the other device is not shown in the skype's config window and never probed with open or ioctl's; I stopped both webcamd proc and launched only the one for the external cam: # ./webcamd -d ugen4.4 (for the external, gives now /dev/video0) and the device /dev/video0 is probed by skype on start and is just working fine; Now I altered the order of the start of the two webcamd proc, i.e. the external was now created as /dev/video0 and the built-in as video8; in skype now only the external is presented and working; The only conclusion I can draw from this is that the older skype 2.0.0.72,1 ignores /dev/video8; I was not able to create /dev/video1 by launching webcamd with -v 1; using -v only gives video8, video16, video24 for 1, 2 and 3 resp., all are not seen by skype; It must be a skype bug, I think.
