7.8.4 General Purpose Input (GPI)
Figure 14: General Purpose Input
The GPI settings allow the Media Sequencer to be configured to handle GPI
commands. The commands can be handled by the Media Sequencer itself (Server
Command) or forwarded to the VCP client (Macro Command).
Both server and client side commands are profile specific, meaning that the
profile determines which VCP client and potentially which Viz Engine(s) that
should execute a client and/or server command. It is therefore very important to
assign the correct profile for each GPI action as they refer to unique profiles
configured per VCP client.
For example; A VCP client has its own profile with two Viz Engines (program and
preview) and receives a client command from a GPI on the Media Sequencer. The
command executes some logic on the VCP client that issues commands to the
program renderer. If the correct profile is not set, such commands might end up
on the wrong VCP client and potentially on the wrong program renderer. The
same would happen if the GPI action was defined as a server command; however,
it would then trigger commands from the Media Sequencer to the Viz directly and
not through the VCP client.
