Dear Dele,
I'm using Jitsi 1.2 in Openfire 3.9.1 in Ubuntu. The Ofmeet works perfectly till any one of the participant share's his Desktop Screen and the conference gets freezed. Upon searching here in the discussions I found a similar issue by Adam Crane (http://community.igniterealtime.org/thread/51791) and by default "enable-usermedia-screen-capture" flag in chrome was enabled and upon clicking the 'share desktop' button the Rayo Failure error was appering on the console with no desktop sharing. However after disabling the flag the desktop sharing started only in single mode but immediately freezes when a second particpant joins the conference.
Please do suggest me as how clear this issue as there are no error logs appering in the Openfire server nor the Chrome console is generating any errors.
Regards,
