    "Could not connect to video device (/dev/video0), please check connection" error

    The title of the thread is what I get when I turn on Camorama. I have done a quick search in the forums and found:

    http://newyork.ubuntuforums.org/show....php?t=1299976

    So Im executing those same commands, to try to know the reason of the error message:

    In another post (I cant recall which one) I found a post that said that if that message appears (Could not connect...), that means that the OS recognizes that there is an installed webcam (in my case is an eyeshot one that comes pre installed with the laptop). Please confirm if this is true or not.

    for lsusb:

    Code:
    lsusb

    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

    Realtek semi... doesnt look like a webcam to me, please correct me if wrong

    For -la /dev/video0:

    Code:
    ls -la /dev/video0
    ls: cannot access /dev/video0: No such file or directory
    However, if I type ls -la /dev/v*:

    Code:
    ls -la /dev/v*

    And for camorama -D:

    Code:
    camorama -D
    VIDIOCGCAP  --  could not get camera capabilities, exiting.....
    It seems that Ubuntu 10.04 doesn't recognize the embedded webcam of my laptop. Now, if any of you has any other command that I should run, please share.

    Cheers

    I was having similar difficulties when trying to use camorama. In the end, I realized that this is really a problem of camorama only. My webcam works fine with gstreamer-properties and cheese.

    me too, seems like development stopped in 2006. Somebody needs to take this app over, it is way too old. Can't believe we hardly have any choice when it comes to webcams in Ubuntu, just cheese (which always breaks) and wxCam which is a bit futzy. Time to get a sponsor an app programme going becaus e we like a distro where the only cool apps are sound apps. Every other app except gimp, sucks.
