I have updated the 'videoswitch' program that controls the video MUX. It now includes the ability to query the video mux for the channel mapping:
controls@pianosa:~ 0$ /opt/rtcds/caltech/c1/scripts/general/videoswitch -h
Usage:
videoswitch [options] [OUT] List current output/input mapping [for OUT]
videoswitch [options] OUT IN Set output OUT to be input IN
Options:
-h, --help show this help message and exit
-i, --inputs List input channels and exit
-o, --outputs List output channels and exit
-l, --list List all input and output channels and exit
-H HOST, --host=HOST IP address/Host name
controls@pianosa:~ 0$
