Ofmeet screensharing "unable to switch video stream"

I got this error message when I switch to screen sharing. jitsi clients can only chat.

video and audio works in the browser.

focus had the right jid.

Used ofmeet version: 0.1.8

browser: chromium and chrome: 43.0.2357.130 Ubuntu 14.04 (64-bit)

The error.log doesn’t react.

jitis video bridge is used.

Openfire version: 3.10

The JavaScript console shows the following message:

the information.log shows the following:

2015.07.16 14:15:17 org.jitsi.videobridge.openfire.Config - Config servlet

2015.07.16 14:15:18 org.jitsi.jicofo.openfire.FocusComponent - handleIQSet

What could be my mistake? I’ve used the default configs.

Unfortunately, I can read your screen. The image is too small. The openfire log messages are for a failed login and not anything to do with screenshare.

Oh sorry, the picture-cutting-tool has changed the resolution. And the log-files didn’t show nothing when i like to switch the video stream
