I am on a mac.
Also, and more challenging, could I run two separate projectors, with different videos, that sync, off one RP?
Thanks for responding! Would piwall work to run two separate videos looping continuously (for the 7 week installation)? I just need the two separate videos to begin at the same time and stay in sync with each other. I have 2 RPi with looper on there from adafruit but it will be too hard to get them to sync.DougieLawson wrote:Get one RPi per projector and run your sync'd stuff with http://piwall.co.uk.
that would be perfect. How can I do that?[/quote]colleen wrote:.... you could run 2 videos independently from one RPi.
thanks so much. I am so absolutely new to this so this is way over my level of understanding. I somehow got the RPi going and with looper but that is because I found a step by step tutorial that I just followed. I may just insert the two memory sticks at the exact same time so they are in sync. I was able to do this once- they are about .5 second off but I can live with that. as long as I keep the RPis powered up they will loop forever this way. And then I will just turn projectors on and off each day- the loop just keeps going and is not affected by the projector. If there is a power outage I will have to re-sync the RPis-- hopefully this won't happen. But I ordered 2 long hdmi cords so I will have access at ground level to the players and can manually slot the thumb drives at the same exact time.DougieLawson wrote:You may need to write your own software. Take a look at MQTT (with Mosquitto) as a way to send a message (publish) that will sync your subscribers.
If your clocks are sync'd then a message that says "start video #3 @ 07:47" would mean they'll start at the same time.
thank you for this information. I am afraid it is way above my understanding, unfortunately!tvjon wrote:that would be perfect. How can I do that?colleen wrote:.... you could run 2 videos independently from one RPi.
these are the two things I used to first, install an OS on the Pi, then to load looper. It took some time to figure it all out- but it worked. Good luck!micknarshall wrote:Hi Colleen,
I'm also an artist trying to do the exact same thing as you. Any chance you could post the step-by-step tutorial you used for setting the RP3 up for projection? I think I'm going to take the same route that you did and just hook them up at the same time and let the device run continuously.
Many thanks in advance!
