Try it online at https://letsmeet.no. You can add /roomname to the URL for specifying a room.

Features

• Local Recording

Local Recording

• Local Recording records the browser window video and audio. From the list of media formats that your browser supports you can select your preferred media format in the settings menu advanced video menu setting. MediaRecorder makes small chucks of recording and these recorded blob chunks temporary stored in IndexedDB, if IndexedDB implemented in your browser. Otherwise it stores blobs in memory in an array of blobs. Local Recording creates a local IndexedDB with the name of the starting timestamp (unix timestamp format) And a storage called chunks. All chunks read in an array and created a final blob that you can download. After blobs array concatenation as a big blob, this big blob saved as file, and finally we delete the temporary local IndexedDB.

• WARNINIG: Take care that You need for local recording extra cpu, memory and disk space. You need to have good enough free disk space!! Keep in mind that Browsers don't allow to use all the disk free capacity! See more info about browsers storage limits:

  • https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API/Browser_storage_limits_and_eviction_criteria#storage_limits
  • https://chromium.googlesource.com/chromium/src/+/refs/heads/master/storage/browser/quota/quota_settings.cc#68

• If there is an error during recording, or browser crashed or you accidentally close your tab, you can recover and save to file your data stored in the IndexDB with the following way. Open browser console and run function CLIENT.recoverRecording(DB_NAME) Where DB_NAME is the name of Indexed DataBase, so the starting date in unix timestamp format of the recording. If you open your browser developer console and find IndexDB storage info, you can find the name of your IndexedDB recording. It is a unix timestamp, the timestamp of the start of your recording.

Package Installation

If you want to install it on the Debian & Ubuntu based operating systems.

• Prerequisites: edumeet will run on nodejs v14.x (tested with v14.15.4 version). To install see here here.

• Download .deb package from here (job artifact)

• Unzip the file

$ unzip edumeet.zip

• Install the package

$ sudo apt install edumeet/edumeet.deb

• After package installation, don't forget the configure ip address in config file.

$ sudo nano /etc/meeting/server-config.js

• Finally, start the service by (it's enabled by default)

$ sudo systemctl start edumeet

Manual installation

• Install all the required dependencies and NodeJS v14 (Debian/Ubuntu):

sudo apt install -y curl git python build-essential redis openssl libssl-dev pkg-config
curl -fsSL https://deb.nodesource.com/setup_14.x | sudo bash -
sudo apt update && sudo apt install -y nodejs

• Install the Yarn package manager (recommended):

curl -sL https://dl.yarnpkg.com/debian/pubkey.gpg | gpg --dearmor | sudo tee /usr/share/keyrings/yarnkey.gpg >/dev/null
echo "deb [signed-by=/usr/share/keyrings/yarnkey.gpg] https://dl.yarnpkg.com/debian stable main" | sudo tee /etc/apt/sources.list.d/yarn.list
sudo apt update && sudo apt install -y yarn

• Clone the project:

git clone https://github.com/edumeet/edumeet.git
cd edumeet

# switch to the "develop" branch to get the latest version for developing
git checkout develop

• Copy server/config/config.example.js to server/config/config.js :

cp server/config/config.example.js server/config/config.js

• Copy app/public/config/config.example.js to app/public/config/config.js :

cp app/public/config/config.example.js app/public/config/config.js

• Edit your two config.js with appropriate settings (listening IP/port, logging options, valid TLS certificate, don't forget ip setting in last section in server config: (webRtcTransport), etc).

• Set up the browser app:

cd lib-edumeet

# using Yarn (recommended)
yarn && yarn link

# using NPM
npm i && npm link

cd ../app

# using Yarn (recommended)
yarn link lib-edumeet && yarn && yarn build

# using NPM
npm link lib-edumeet && npm i && npm run build

This will build the client application and copy everything to server/public from where the server can host client code to browser requests.

• Set up the server:

cd ../server

# using Yarn (recommended)
yarn && yarn build

# using NPM
npm i && npm run build

Run it locally

• Run the Node.js server application in a terminal:

cd server

# using Yarn (recommended)
yarn start

# using NPM
npm run start

• Note: Do not run the server as root. If you need to use port 80/443 make a iptables-mapping for that or use systemd configuration for that (see further down this doc).
• Test your service in a webRTC enabled browser: https://yourDomainOrIPAdress:3443/roomname

Deploy it in a server

• Stop your locally running server. Copy systemd-service file edumeet.service to /etc/systemd/system/ and check location path settings:

cp edumeet.service /etc/systemd/system/

# modify the install paths, if required
sudo edit /etc/systemd/system/edumeet.service

• Reload systemd configuration and start service:

sudo systemctl daemon-reload
sudo systemctl start edumeet

• If you want to start edumeet at boot time:

sudo systemctl enable edumeet

Ports and firewall

• 3443/tcp (default https webserver and signaling - adjustable in server/config.js)
• 4443/tcp (default npm start port for developing with live browser reload, not needed in production environments - adjustable in app/package.json)
• 40000-49999/udp/tcp (media ports - adjustable in server/config.js)

Load balanced installation

To deploy this as a load balanced cluster, have a look at HAproxy.

Learning management integration

To integrate with an LMS (e.g. Moodle), have a look at LTI.

TURN configuration

• You need an additional TURN-server for clients located behind restrictive firewalls! Add your server and credentials to server/config/config.js
