This is a fork of https://github.com/jibon57/bbb-recorder and modified very little to suit some specific use cases.
Bigbluebutton recordings export to webm
or mp4
& live broadcasting. This is an example how I have implemented BBB recordings to distibutable file.
- Videos will be copied to
./recordings
- Can be converted to
mp4
. Defaultwebm
- Specify bitrate to control quality of the exported video by adjusting
videoBitsPerSecond
property inbackground.js
- xvfb (
apt install xvfb
) - Google Chrome stable
- npm modules listed in package.json
- Everything inside
dependencies_check.sh
(run./dependencies_check.sh
to install all)
The latest Google Chrome stable build should be use.
curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add
echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" > /etc/apt/sources.list.d/google-chrome.list
apt-get -y update
apt-get -y install google-chrome-stable
FFmpeg (if not installed already & have plan for mp4 or RTMP)
sudo add-apt-repository ppa:jonathonf/ffmpeg-4
sudo apt-get update
sudo apt-get install ffmpeg
Clone the project first:
git clone https://github.com/tawkirahmed/bbb-recorder
cd bbb-recorder
npm install --ignore-scripts
node export.js "https://BBB_HOST/playback/presentation/2.0/playback.html?meetingId=MEETING_ID" meeting.webm 10 true
Options
You can pass 4 args
- BBB recording link
- Export file name. Should be
.webm
at end - Duration of recording in seconds. Default 10 seconds
- Convert to mp4 or not (true for convert to mp4). Default false
You can also use liveJoin.js
to live join meeting as a recorder & perform recording like this:
node liveJoin.js "https://BBB_HOST/bigbluebutton/api/join?meetingId=MEETING_ID...." liveRecord.webm 0 true
Here 0
mean no limit. Recording will auto stop after meeting end or kickout of recorder user. You can also set time limit like this:
node liveJoin.js "https://BBB_HOST/bigbluebutton/api/join?meetingId=MEETING_ID...." liveRecord.webm 60 true
Sometime you may want to broadcast meeting via RTMP. I did some experiment on it & got success but not 100%. To test you can use ffmpegServer.js
to run websocket server & liveRTMP.js
to join the meeting. You'll have to edit rtmpUrl
& ffmpegServer
info inside config.json
file (if need).
- First run websocket server by
node ffmpegServer.js
- Then in another terminal tab
node liveRTMP.js "https://BBB_HOST/bigbluebutton/api/join?meetingId=MEETING_ID...."
You can also set duration otherwise it will close after meeting end or kickout:
node liveRTMP.js "https://BBB_HOST/bigbluebutton/api/join?meetingId=MEETING_ID...." 20
Check the process of websocket server, ffmpeg
should start sending data to RTMP server.
Note:
If presenter do nothing in the meeting room that time ffmpeg
may exit with error & will try to reconnect again. So, it's recommend from me to keep webcam on. Actually I don't have much experience on ffmpeg
to resolve those problems. Please contribute your experience.
When you will run the command that time Chrome
browser will be open in background & visit the link to perform screen recording. So, if you have set 10 seconds then it will record 10 seconds only. Later it will give you file as webm or mp4.
Note: It will use extra CPU to process chrome & ffmpeg.
We are offering cheaper Bigbluebutton shared hosting or Bigbluebutton installation/configuration/loadbalance service. You can send me email jibon[@]mynaparrot.com
