Record Zoom meetings automatically in headless docker container with Python and FFmpeg

zoomrec

A all-in-one solution to automatically join and record Zoom meetings.

---

• Python3 - Script to automatically join Zoom meetings and control FFmpeg
• FFmpeg - Triggered by python script to start/stop screen recording
• Docker - Headless VNC Container based on Ubuntu 20.04 with Xfce window manager and TigerVNC
• Telegram - Get notified about your recordings

---

Join with ID and Passcode	Join with URL

Installation

The entire mechanism runs in a Docker container. So all you need to do is install Docker and use the image from Registry.

Requirements

• Docker - https://docs.docker.com/get-docker/

Docker Registry

Docker images are build and pushed automatically to Docker Hub and GitHub Container Registry.

So you can choose and use one of them:

• ghcr.io/kastldratza/zoomrec:master
• kastldratza/zoomrec:latest

For my examples in this README I used kastldratza/zoomrec:latest

Usage

• Container saves recordings at /home/zoomrec/recordings
• The current directory is used to mount recordings-Folder, but can be changed if needed
  • Please check use of paths on different operating systems!
  • Please check permissions for used directory!
• Container stops when Python script is terminated
• Zoomrec uses a CSV file with entries of Zoom meetings to record them
  • The csv can be passed as seen below (mount as volume or add to docker image)
• To "say" something after joining a meeting:
  • paplay (pulseaudio-utils) is used to play a sound to a specified microphone output, which is mapped to a microphone input at startup.
  • paplay is triggered and plays a random file from /home/zoomrec/audio
  • Nothing will be played if directory:
    • does not contain .wav files
    • is not mounted properly

CSV structure

CSV must be formatted as in example/meetings.csv

• Delimiter must be a semicolon ";"
• Only meetings with flag "record = true" are joined and recorded
• "description" is used for filename when recording
• "duration" in minutes (+5 minutes to the end)

weekday	time	duration	id	password	description	record
monday	09:55	60	111111111111	741699	Important_Meeting	true
monday	14:00	90	222222222222	321523	Unimportant_Meeting	false
tuesday	17:00	90	https://zoom.us/j/123456789?pwd=abc		Meeting_with_URL	true

VNC

You can connect to zoomrec via vnc and see what is happening.

Connect (default)

Hostname	Port	Password
localhost	5901	zoomrec

Telegram

Zoomrec can notify you via Telegram about starting and ending a recording or if joining a meeting failed. All you need is a bot token and a chat id of a Telegram channel.

At first create a new telegram bot to get the bot token. After that create a new channel and add the bot with sufficient permissions to write messages in that channel. Finally get the chat id of your channel and look below how to pass your Telegram details to Zoomrec.

Preparation

To have access to the recordings, a volume is mounted, so you need to create a folder that container users can access.

[ IMPORTANT ]

Create folders and set permissions (on Host)

mkdir -p recordings/screenshots
chown -R 1000:1000 recordings

mkdir -p audio
chown -R 1000:1000 audio

Flags

Set timezone (default: Europe/Berlin)

docker run -d --restart unless-stopped \
  -e TZ=Europe/Berlin \
  -v $(pwd)/recordings:/home/zoomrec/recordings \
  -v $(pwd)/example/audio:/home/zoomrec/audio \
  -v $(pwd)/example/meetings.csv:/home/zoomrec/meetings.csv:ro \
  -p 5901:5901 \
  --security-opt seccomp:unconfined \
kastldratza/zoomrec:latest

Set debugging flag (default: False)

• screenshot on error
• record joining
• do not exit container on error

docker run -d --restart unless-stopped \
  -e DEBUG=True \
  -v $(pwd)/recordings:/home/zoomrec/recordings \
  -v $(pwd)/example/audio:/home/zoomrec/audio \

docker run -d --restart unless-stopped \
  -e TELEGRAM_BOT_TOKEN="YOUR_BOT_TOKEN" \
  -e TELEGRAM_CHAT_ID="-100_YOUR_CHAT_ID" \
  -v $(pwd)/recordings:/home/zoomrec/recordings \

cd example

# Build new image by customized Dockerfile
docker build -t kastldratza/zoomrec-custom:latest .

# Run image without mounting meetings.csv and audio directory
# Linux
docker run -d --restart unless-stopped -v $(pwd)/recordings:/home/zoomrec/recordings -p 5901:5901 --security-opt seccomp:unconfined kastldratza/zoomrec-custom:latest

# Windows / PowerShell
