Museum Looper
This is a looper for multi-screen video installations at museums for raspberry pi. It's not the greatest code, but works reliably.
Based on
- A modified version of omxplayer-sync (unclear license)
- OSC.py (LGPL)
PREPARE
You will need ...
- A certain amount of raspberry pi 3 or 4 with raspbian installed
- An unmanaged switch and network cables to connect them
- Some kind of wifi/public hotspot during set up
- One test file for each raspberry (files need to be exactly the same duration)
SETUP ON EACH RASPBERRY
First grab the files and run the setup:
-
Make sure your pi is connected to the internet
-
Copy the files in this repository to /home/pi/looper
-
Open a terminal and type
cd /home/pi/looper ./setup.sh -
Plug in a usb drive with a single mp4 file, or see "update using your laptop" below
-
reboot
The setup step is a bit intricate. It will enable the ssh server, set a password and a few other things. You will only have to answer basic questions.
Please read the source code in setup.sh. It has an explanation what's going on for each step.
UPDATE VIDEO FILES USING USB
- Empty the usb drive, format it as ext3,ext4 or extfs
- Copy a single mp4 file on the drive
- Plug it into the raspberry you want to
UPDATE VIDEO FILES USING YOUR LAPTOP
Connect your laptop to the unmanaged switch and set the ip to 192.168.0.240, now you can update your files using
rsync --progress my_file_1.mp4 pi@192.168.0.114:/home/pi/Videos/main_video.mp4
rsync --progress my_file_2.mp4 pi@192.168.0.115:/home/pi/Videos/main_video.mp4
etc.
