Omxplayer multiples play bug. Over wlan or lan

[FabriceA]

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!!
