Users: Use Vidyo on Linux

!!! IMPORTANT !!! Vidyo stopped releasing a new Vidyo Desktop clients for Linux. As a replacement please connect with our WebRTC client (see below the Alternatives for Linux)

This page provides user guidelines and technical notes for the latest release of the Linux VidyoDesktop client. 

Tested Distributions and Environments

The last release of the Vidyo Desktop client was tested in several Linux distributions (32/64-bit) including:

  • Ubuntu 14.04
  • CERN CentOS Linux 7

Although VidyoDesktop may be installed and run on other distributions, they are not officially supported by Vidyo as of the writing of this note. Vidyo Desktop 3.6.3 is the last release of Vidyo Desktop for Linux. Vidyo stopped releasing a new version for Linux and they will release a new version only for Windows and Mac platform. Linux users on Ubunty 14.04 and Cern CC 7, can still use the last Vidyo Desktop 3.6.3 . If you have Ubuntu 15.04 and higher, you can install VidyoDesktop by followiong thi How to:

User with other distribution should use our WebRTC client(see below for Alternatives for Linux) to connect to Vidyo meetings.  

Alternatives for Linux 

If you have recurrent problems using your Vidyo client on your Linux Desktop or you are running a non-supported distro, you can access a Vidyo meeting with VidyoConnect WebRTC client. This client is a default one, if you are accessing a Vidyo meeting from indico and you are on the Linux platform. If you wat to start the client not from the indico link, simply use Chrome or Firefox browser and go to , use portal: and login with your CERN account. 

If you have difficulties to connect or you are disconnected after few seconds, please check if your firewall is open. You can find all the ports needed on our service page:


Another possibility is to join the Vidyo Room via SIP using Linphone:

To connect use just dial one of the IVRs available (at CERN or Internet2) using the followingf syntax:

3VidyoMeetingExtension'@' or 3VidyoMeetingExtension'@'

If the meeting is protected by a PIN:

3VidyoMeetingExtension*PIN'@' or 3VidyoMeetingExtension*PIN'@'

For the list of Vidyo Gateways IVRs hostnames and IPs and general information about H323/SIP support, please refer to:

I concur. None of the clients work for me (VidyoDesktop on Fedora 26 with Wayland, WebRTC client with FF v55-57 nor with Chrome). It's time for CERN to find an alternative...preferably an open-source one that can be maintained with the assistance of CERN if need be.

I have a similar issue with the vidyo webRTC: sometimes I am in a Vidyo room where people can hear me, but the webRTC does not give me sound. It seems to happen randomly when no CERN room is connected. Clearly a bug in vidyo.

On a Fedora 26 installation, I have so far had the following Vidyo experience.

The WebRTC client works for me in Firefox. after I installed the audio codecs from the rpmfusion repository.

dnf install gstreamer1-plugins-base gstreamer1-plugins-good gstreamer1-plugins-ugly gstreamer1-plugins-bad-free gstreamer1-plugins-bad-free gstreamer1-plugins-bad-freeworld gstreamer1-plugins-bad-free-extras ffmpeg

I am afraid I do not know exactly which package solved the issue.

In Chrome, I connect to the room but do not get any sound.

The VidyoDesktop application has a crash on startup.

As far as I remember, support for Linux was a key requirement, when Vidyo was chosen. If this requirement is not fulfilled anymore, this means the replacement should be find, and contract with Vidyo should dissolved.
It is frustrating, how many CERN users must do hacks and tricks to get running a basic collaborative tool on Linux, platform, which is primary choice for most of them. webRTC is not real alternative yet.
Not mentioning, that many features, promised at the beginning (like muting of remote participants) are still not available.
I hope IT will take this seriously, and either negotiate with Vidyo further support for Linux, or start to look for replacement.

people are already voting with their feet. I attend an ever-increasing number of phone-only (sometime with readytalk support), and zoom meetings (zoom works just fine on linux). The question is whether CERN IT wants to move on, or to be left behind

Very bad service. Does not work on Ubuntu 16.04, hangs the system after a few minutes. On Gentoo it works except sharing the screen. Webrtc is just buggy. The only place where it works for me more or less was Android, but obviously no way to share the screen there. Every remote connection to an important meeting, when stability is important, becomes a nightmare.
