Hi,
I use your script for multiples raspberry pi3b+ playing under the control of QLab 4.7.2.

It's as if it received the same command several times at the same time, perhaps through interference in the network... which it would interpret as a double or multiple command. Is there any way to prevent app.js from not multiplying the orders, at least for a second?

Thank you!!

OMXPlayer is deprecated in favor of VLC player.
I've used this project in a couple shows and greatly appreciated the utility. An update to allow a build on modern hardware would be greatly appreciated.

Thanks for making your project public.

I followed the install steps on my RPI4.
After running sh install.sh the PI rebooted and eventually the desktop shows.
I assume to start the player I need to npm start or something?

But I am not able to make it run.

I did test that npm is installed with npm list and get:

Thanks for any tips.

The install.sh throws several errors while installing, and then (obviously) won't run properly.

Here's where the errors seem to start:

I'm trying to install on a pi zero - could that be the problem?

Edit 3/19/19 - picked up a pi 3b+ and it works fine there. Would still like to be able to run it on a zero if possible - great footprint to put in props!

I have an Error: cannot find module 'osc'
If i check:
node /osc-node/app.js

Any idea where to look to fix this?
Can it be that i'm not the standard user "pi"?

Hello,

When running this the install it crashes my Pi3B+,

When it reboot's the display is black, ssh still works but im unable to see the display.

only way to get display back is to format SD card and start again.

Hoi Ik was benieuwd of je aleens geprobeerd had om dit te gebruiken op een Pi 4.

en dan 2 verschillende projectoren te bedienen met lab.

dit ben ik aan het proberen voor elkaar te krijgen maar helaas zonder succes.
ik kan niet ontdekken waar de displays aangesproken worden.
door middel van terminal kan ik wel beide schermen een eigen filmpje laten vertonen

ik hoor graag of je mij een richting in kunt sturen

Groetjes

Hey, first of all thanks for the code !

I changed the Port to 56000 to match the "ctrl" app for iPad. Qlab is just working fine.
Via "ctrl" from ON LX (https://onlx.ltd/ctrl-for-ipad) I can /pause /stop and /cmd but when I try to start a video with /loop or /play the video wich was playing back (startet on Qlab) stops but the new video isn't starting.

do you have any suggestions where to look at, seems to be a path problem...

Thanks,
Lexi
