# FAQ Jitsi / Meet

This source provides a comprehensive list of frequently asked questions and technical troubleshooting steps for the Jitsi Meet web conferencing service provided by the Universitätsrechenzentrum (URZ) at Universität Greifswald.

## Key Operational Details
- **External Access**: External participants can join a conference once a university member has opened the room.
- **Room Persistence**: Rooms are ephemeral. They exist only while participants are present (as long as at least one participant is present). All settings, including passwords, are wiped/deleted once the last person leaves and the room is empty.
- **Moderation**: The person who opens the room or logs in via the [[zentraler-nutzeraccount]] is assigned the "Moderator" role (indicated by a star symbol). Moderators can mute or remove participants.
- **Participant Rights**: All users/participants have equal rights regarding audio, camera, and screen sharing.
- **Presentations**: There is no dedicated presentation mode; users must use the screen sharing feature. Video and screen sharing can operate simultaneously.

## Technical Configurations and Workarounds
- **Bandwidth Optimization**: By default, the tile view only shows the last two active speakers.
- **View Override**: Users can see all active speakers/force the display of all participants by appending `#config.channelLastN=-1` to the conference URL or room name (e.g., `meetings.uni-greifswald.de/RoomName#config.channelLastN=-1`).
- **Android App Bug**: A known communication error exists in Jitsi Meet build 21.6.0 on Android, preventing room creation/entry after a cache clear or reinstall. The recommended workaround is using the **Chrome Browser** in "Desktop Mode."

## Troubleshooting
- **Audio/Video Issues**: Often caused by local network firewalls or browser extensions (e.g., uBlock, AdBlock) that block tracking. Users are advised to disable these extensions for `meetings.uni-greifswald.de`.
- **Performance**: Lagging in the app may be caused by multiple running instances or residual/orphaned background processes from previous sessions.

## Support
Technical support is provided by the URZ via the [[groupware]] ticket system or the hotline (ext. 1420).
