Select random video input device from dynamic enum

[tonfilm]

It is indeed easier if you make a Spread of all textures of the video inputs with a Cons node and then use GetSlice with a random index for every quad.

For nodes that generally work with dynamic enums have a look at the data types starting with IDynamcEnum, there you’ll find things like SelectIndex and so on. But note that changing the device on a VideoInput will most likely freeze the application for a few frames, so it isn’t recommended to do that during a show.
