I only use jriver at this time for music. There are commands in the builder for play/pause, stop, skip, etc. and they work perfectly with the computer running jriver's IP address set up as an http gateway on port 52199.
In android I launch the gizmo app for selecting music. I use an embedded webgizmo page to do the same in iOS.
I use a Dune play for video. Though with a recent remodel at my house I may start to use jriver more for that as a 2nd option.
