Thanks a lot, David!
You've just opened my eyes! It may be not so clear to understand how, but
in fact it is so. We can add a switch to airtime stream settings telling
script generator whether we're working with video or not and setting a
trivial boolean variable. This var can be used to determine if we should
work with audio only functions or with video-oriented ones.
Your advice about using a kinda filler when video becomes unavailable is
also useful for achieving our goal to add live video streaming to airtime.
I guess, when video will suddenly disappear in stream, liquidsoap can
crash, and a filler would solve that potential issue.
