    I notice several times: unsupported, but could not paste whole text in message.
    Is there any suggestions how to fix it? Or does it mean that I have to buy other webcam?

    I need to buy other webcam, what should I look for?

    Regards,

    Mathieu

    That is a uvc compatible web cam. IMHO obtaining a uvc compatible web cam is the best you can do.

    IMHO if there is a problem here it is likely to do with gstreamer support to empathy and not with your webcam. Likely you are missing a gstreamer plugin or a v4l app and need someone who knows what openSUSE gstreamer plugins (or v4l) are needed to help here.

    I don't use empathy so can't help any more here.

    Thanks for the answer, I'll have a look into that direction then.

    I have been trying to get somewhere with your tips... But no result so far, Get message in Empathy: Busy, ... and no reason specified.

    Hope someone still has a tip.

    Busy ? That suggests some other device is accessing the webcam.

    What happens if IMMEDIATELY after a boot you try Empathy. Note that as far as I know, only one application at a time can use the webcam. Device sharing for webcams is not implemented to the best of my knowledge.

    When I go straight to Empathy and try webcam from there, get unspecified error. Account goes to disconnected to I see.
