Jitsi is an open source high quality video conferencing application with low latency.
This application has been developed for ad hoc video calls. The more participants you have in a call, the more resources you need for your hardware.
For best use, you are advised to limit the total amount of participants to six.
If you are planning on a conference exceeding 6 participants, you should keep the usage of video and audio streaming as low as possible.
Notice: The RHRZ is running the Jitsi server but cannot provide support for your conferences. We do appreciate your understanding.
Starting a Jitsi video call in your browser
Use Chrome Browser or Jitsi Client only to avoid interferences affecting all participants.
Prerequisites for use of Jitsi
- Webcam/Microphone: If you should use a newer generation notebook, the required hardware should be installed. You may have to activate the appliances. As an alternative you may want to use an external webcam and headset with a built-in microphone.
- Client: An additional client should not be necessary. The entire application is browser-based.
Initiating/ Starting a webconference
- Start your browser and type https://jitsi.rptu.de in the address field.
- Enter your self-selected web conference name in the field to the left of the "Start meeting" button or simply use one of the automatically generated names suggested by the system.
- By pressing the "Start meeting" button you initiate the start of your web conference.
- A new pop-up window will appear and you will see a button called „Zulassen“ - „Permit“. By pressing the button, you will authorize your browser to gain access to your webcam and microphone.
- If you are the first participant of the conference you will be the moderator, admin at the same time.
Invite more people
To invite other people, you simply need to provide the URL of your web conference, e.g. in an invitation email as a link to the conference. You can simply copy the URL from the address bar of your browser window and paste it into the invitation email.
You will find further options for inviting additional people via the attendees window. (see Control panel -> Attendees)
If you have assigned a password for the web conference in the security options (under "Other settings"), it is best to communicate the password in a separate message.
The invited persons can now join the web conference by calling up the conference link sent (and entering the password if necessary).
The control panel
If you move the mouse pointer over the control panel, the function of the individual buttons is displayed. The following is a brief overview of the panel functions from left to right:
Activate / deactivate mute (sound settings)
By clicking on the microphone button, you can specify whether your microphone is active or muted. If the microphone button is shown with a dash, your microphone is currently not active.
(Clicking on the small up arrow ^ takes you directly to the sound settings, where you can select and test the available output and input devices).
Start / stop camera (video settings)
By clicking on the camera button, you can determine whether your camera is active and the video image is transmitted to the other participants. If the camera button is shown with a dash, your camera is not active at the moment.
(Clicking on the small up arrow ^ takes you directly to the video settings, where you can select and test the available output and input devices).
Screen sharing
By clicking on this button, you can share individual application windows or the entire desktop instead of your camera image. The first time you use it, you will be prompted to install a plugin (depending on your browser version). If screen sharing does not work immediately after installing the plugin, it usually helps to reload the page. The current version of Google Chrome no longer requires a plugin.
Open / close chat
Clicking this button opens the chat window on the left-hand side of the browser window. Here you can exchange short text messages with the other web conference participants by entering text in the input field.
Report
Use this symbol to virtually raise your hand to signal your wish to speak. In many cases, this facilitates communication in a video conference. When you click on the button, a blue symbol with a hand appears in your preview image. If you click again, it disappears again.
Present (invite more people)
By clicking on the symbol, a list of those present appears on the right-hand side of the browser window.
(You will also find the "Invite person" button above the list. Click on this button to open a pop-up window. There you can copy the conference link to the clipboard and share it with other people).
