webcam (v4l2) does not work with kopete

[martinellison]

My webcam works with Video for Linux 2 (v4l2) and VLC, but not with kopete. If I run kopete from the command line I get messages like:

~> VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument
VIDIOC_ENUMSTD: Invalid argument
VIDIOC_ENUM_FMT: Invalid argument
VIDIOC_S_INPUT: Device or resource busy
VIDIOC_S_INPUT: Device or resource busy
VIDIOC_REQBUFS error 16, Device or resource busy
VIDIOC_STREAMON error 16, Device or resource busy
QObject::connect: Cannot connect (null)::onlineStatusChanged(Kopete::Contact *, const Kopete::OnlineStatus &, const Kopete::OnlineStatus &) to Kopete::Identity::updateOnlineStatus()
VIDIOC_DQBUF error 16, Device or resource busy
VIDIOC_DQBUF error 16, Device or resource busy
VIDIOC_DQBUF error 16, Device or resource busy
VIDIOC_DQBUF error 16, Device or resource busy
VIDIOC_DQBUF error 16, Device or resource busy
QColor::setNamedColor: Unknown color name 'fafafa'

and then much more of the last two messages. The configure panel in kopete just gives the green box.

v4l2-tool also appears to work. Also, I don't have a /dev/v4l/by-path/ direcvtory.

Does anyone know how to fix this? Presumably, something else has grabbed the video feed, but what? How do I find out?
