Very impressive! Doing all that as a plugin is some smart plugin
For a VDR internal method things would get easier, no need to
pre-allocate dummies. Cleaning up the mess however is not as easy.
How did you solve the case that a device disappears while being used? If
this happens for a recording, then VDR would terminate with a VDSB, or?
Do you silently switch the device to another resource?
