I am not sure if/how this works with RDP directly, but there are other products out there that can do this (I am not sure if they use the RDP protocol directly, or if they install an agent etc.)
Hi! It`s great idea! Now we use ObserveIT for Linux gateway and Netwrix User Video Record for Windows gateways.
I`d like to use Royal Server, but now RS haven`t screen recording. Could you include in road map this feature?
