We are deploying the latest version of cucilync (9.2.5) which is now based on the Jabber framework and contains the Cisco PVE (precision video engine), inherited from Tandberg Movi.
On the current workstations, there is also Cisco Jabber Video (formerly Movi) deployed. The CPU of the workstations are only dual core but "Movi" was able to maintain bidirectional 720p @30fps calls, perfect quality.
With Cucilync, the maximum resolution I got with the same OS and Hardware is 768x432 @30fps. The quality is really not nice... I guess it's the same with Jabber for Windows since it's the same engine.
I cannot find any documentation stating what is the minimum requirements to do HD calls with Cucilync 9.x or Jabber for windows.
Since cucilync and jabber implement the PVE engine of movi, I assume the video capabilities and quality should be the same... But it's not, according to my real-life tests.
Thank you for your feedbacks if you have any information.
