fvnet ā€” Explore and retrieve from FireVision instances on the network

Synopsis

fvnet -e
fvnet -s -n host[:port]]
fvnet <-i|-j|-c|-C> -n host[:port]]/id file

Description

Explore FireVision instances on the network and interact with those instances. In the first form the network is explored using mDNS-SD service discovery to find FireVision Fountain instances. These are then queried for existing images and lookup tables.

In the second form the available images and lookup tables are queried from a specified host.

The third form finally allows for retrieving images and retrieving or pushing colormaps reading from or writing to file.
