I'm afraid I don't feel technically able to comment on more recent posts
in this thread, but I've just removed the 'trunk' version from the wiki
and posted a new one, identified by today's date, in which the polarity
is controlled by editing a single variable and can be checked before
first use, and the PID streams can be selected automatically with
timeout for user interaction or directly from the command line. I think
the 'cutting' part is functionally unchanged.
PID selection can be a personal as well as a technical or national
choice and some modification of the script may well be called for.
The script chooses the first-listed from "ffmpeg -i". That usually
works for me.
