On Archlinux:
$sudo pacman -S gst-plugins-bad

On Ubuntu (in Mint and Debian the package name+ installation should be pretty
much the same/similar):
$sudo apt-get install gstreamer0.10-plugins-bad 

On Fedora (not sure which one of these or maybe both):
$dnf install gstreamer-plugins-bad-free 
$dnf install gstreamer1-plugins-bad-free 

That should fix the not working kamoso.

Created attachment 99372

Shutting down gracefully at startup in case of missing plugin.

As promised, a patch for improved error handling. Let me know about it :)

On Chakra, the bad plugins for gstreamer1.0 are also in their own package; once
installed that, kamoso starts up without issues.

I have added the gst-plugins-bad package as a dependency of kamoso, other
packagers should do the same for their distros (e.g. Archlinux).

Error handling inside kamoso could be improved, if there are no objections I'll
send a patch for that later on.

Regarding my comment "but I still cannot get kamoso to find it, i.e.
QGst::ElementFactory::find fails too, not just ::make.", that is because on
Chakra kamoso uses gstreamer-1.0 and not gstreamer-0.10. 

For some reason gstreamer-1.0 does not have the plugin on my system (as shown
by gst-inspect-1.0).

--- Comment #12 from Lisa  ---
More information: the crash is caused by the fact that the element factory
"wrappercamerabinsrc" does not exist on the system, therefore a null element is
returned.

This should be part of gstreamer-bad-plugins. Before installing the bad plugins
I run "gst-inspect-0.10 | grep camera" and got an empty output. After
installing them, I get this:

camerabin2:  camerabin2: CameraBin2
camerabin2:  wrappercamerabinsrc: V4l2 camera src element for camerabin
camerabin2:  viewfinderbin: Viewfinder Bin
bayer:  bayer2rgb: Bayer to RGB decoder for cameras
camerabin:  camerabin: Camera Bin

but I still cannot get kamoso to find it, i.e. QGst::ElementFactory::find fails
too, not just ::make.

for me this problem has gone away, if it has stopped for others too we can
close this bug.
