I'm pretty sure most of the issues are in farstreamer as well. There may be 
also be some issues from some objects not having support in the Qt/Glib 
interface

So, mostly I just want this version to have a release, and I'm sufficiently new 
to KDE not to know how best to do that.

Also what Niels and I did is port it from KDE4 and GStreamer 0.10 to Plasma5 & 
GStreamer 1.0. Most of the core logic is still from  George Kiagiadakis. It 
now works about as well as it did with KDE4 but with newer libraries.

Also its not like there's any KDE client that has better support for video 
chat for XMPP. As far as I am aware the only open source project with better 
XMPP video support is Jitsi. (I think there's some SIP based clients that are 
Qt based that claim support for video, but I haven't tested them).

However if there's a way to make an official "kde extras" or "unstable" release 
that can be easily shipped by distros, I'm totally fine with that too. I would 
rather not ship a git snapshot into Debian proper.
