Vlc-sync

vlc-sync is a modern adaptation of OMXPlayer-Sync, using VLC as a replacement for the deprecated OMXPlayer. This implementation facilitates the synchronization of multiple VLC players across a network, following a conductor/follower model. You are also able to use a single conductor or follower for a simple video loop.

In simple terms, this tool makes it possible synchronize videos playing on different computers (usually Raspberry Pi's) using a program called VLC. The conductor computer sends signals to the follower computers, telling them when to start or loop a video so that they all stay perfectly in sync. This guide exists to replace the outdated Making a video installation with Raspberry Pi tutorial on our wiki.

Getting started

You can use vlc-sync downloading our ready-to-use Raspberry Pi images from our website. If you want to synchronize videos between two Pi's, make sure to download both the conductor and follower images. For a simple video loop you can download either.

Download conductor.img (4.75GB)
Download follower.img (4.36GB)

Flashing the image

To use the downloaded image, you need to "flash" it to the micro SD card the Pi uses. The easiest way to do this is with a program called Etcher. Once you've downloaded Etcher, you can insert the micro SD card in your computer and use Etcher to flash the contents of the downloaded image (either conductor.img or follower.img) to the micro SD card.

From left to right: the image you want to flash, the SD card you've plugged in your computer, the button that starts the flashing process.

Customizing

Both the conductor.img and the follower.img vlc-sync images make it easy to change the settings and the video that should be playing. Insert a thumb drive (USB stick) containing a config.conf and a .mp4 file in the Pi that is running the newly flashed image. The configuration file should be edited to match your intentions. A config.conf file must look like the following:

[video]
file_name = synctest.mp4

[audio]
output = hdmi

[options]
verbose = False
conductor = True
destination = 172.24.1.255

file_name should be set to match the filename of the .mp4 file on the thumb drive.
output can be set to hdmi or analog to use 3.5mm jack as an output device.
verbose can be set to True or False for logging more data to the vlc-sync systemd service. Most users don't need to change this.
conductor can be set to True or False to switch between conductor and follower mode.
destination can be set to a random IP address to avoid conflicts with other installations running on the same network. It is advised to pick a random number between 0 and 200 for the second set of numbers e.g 172.120.1.255. Always end the IP address with 255
