How to sync different videos on differents Raspberry?
I searched for documents but they are old in 2014 and are not up to date.
I use Raspi CM3 that works exactly like a Raspberry pi 3.
If you're ok with using a commercial product, our info-beamer hosted product can do that. You can easily build video walls or individual screens that play either the same content or different content of the same duration in sync. info-beamer works on all Pi versions: There are installations that use the NEC compute module, so the CM3 is fully supported. Let me know if you have any questions.
