Well, there are two problems above: the "Skype V4L2: Could not find a suitable capture format" and the "Skype Xv: No suitable overlay format found". I am trying to fix the first one for now, after that I am going to try to fix the other. As I said before the webcam works with Kopete (64-bit) and with mplayer (32-bit and 64-bit), so the Xv problem must be Skype specific, but I cannot test this problem until I fix the first one. > Markus > > > OBS: compat-ioctl32.ko is being used by the driver so it should > > support 32- bit ioctl. > > > > Em Tuesday 24 March 2009, Lamarque Vieira Souza escreveu: > >> Hi, > >> > >> Em Tuesday 24 March 2009, Hans de Goede escreveu: > >> > On 03/23/2009 09:08 PM, Lamarque Vieira Souza wrote: > >> > > Hi all, > >> > > > >> > > I am trying to make Skype work with my webcam (Creative PC-CAM > >> > > 880, driver zr364xx).
