Galène is a videoconference server (an “SFU”) that is easy to deploy and that requires moderate server resources. It was originally designed for lectures and conferences (where a single speaker streams audio and video to hundreds or thousands of users), but later evolved to be useful for student practicals (where users are divided into many small groups), and meetings (where a dozen users interact with each other).
### Client features:
- multiparty audio and video
- text chat
- reasonably good support for mobile (Android and iPhone/iPad)
- screen and window sharing, including sharing multiple windows simultaneously (not on mobile)
*Galène* meeting rooms are called "groups". Any group is accessible at `https://domain.tld/group/GroupName`, by typing its name in the home page search field, or by selecting it in the public list (if the group is configured as publicly visible, see below).
To create a new group, you need to create a `GroupNameExample.json` file and restart Galène service (you can also make subfolder groups, and the groups will be accessible with `https://domain.tld/group/subfolder/GroupName`). Various configuration options are available (see https://github.com/YunoHost-Apps/galene_ynh/wiki/Configuration-file).
When Galène is removed, the data directory (`/home/yunohost.app/galene/`) is preserved. If you want to remove it along with Galène, use the `--purge` option: `sudo yunohost app remove galene --purge`.
Galène comes with a built-in TURN server that should work out-of-the-box.
- If your server is behind NAT, allow incoming traffic to TCP port `8443` (or whatever is configured with the `-http` option in `/etc/systemd/system/galene.service`) and TCP/UDP port `1194` (or whatever is configured with the `-turn` option in `/etc/systemd/system/galene.service`)
To check if the TURN server is up and running, type `/relay-test` in the chat box. If the TURN server is properly configured, you should see a message saying that the relay test has been successful.
Statistics are available under `/opt/yunohost/galene/stats.json`, with a human-readable version at `domain.ltd/stats.html`. This is only available to the server administrator (the admin/password is set in the `config.json` file: `/opt/yunohost/galene/data/config.json`).
Make sure allow-recording is set in your group configuration. Log-in as an operator, then say `/record` before you start your lecture. Don't forget to say `/unrecord` at the end. You will find your recordings under `https://server.example.com/recordings/groupname/`. The video recordings are stored in `/home/yunohost.app/galene/recordings` folder.
