Your requirement that it do what Samsung All Share does is where I have to write no.
There are players that play content but your requirements are beyond playing AVI and showing JPEGs so if only you had not added a Mount Everest requirement (does all that All Share does.)
https://www.google.com/search?q=video+wall+for+restaurants finds other solutions but fails your requirements about All Share.
Hello,
I have 6 Samsung Smart TV in a restaurant, all connected to a local network.
I use the TVs to show the restaurant menu for clients and I have static .jpeg menu or .avi movie menu.
The software I use now is Samsung All Share ( old software from Samsung ) but it crashes after 2-3 hours of playing and I need my menu to be played 24/24.
Is there any updated free/paid software that can do what Samsung All Share does ? For 6 devices, playlist options and network play via a computer.
Thank you !
