That is weird. Maybe single quotes work differently in your command line, or
are those apostrophes or something?? try moving the first quote after the
equals sign, e.g. channelsplit=‘channel…..[FL][FR]’
But even after it gets the channelsplit working the right channel layout name
is probably stereo, and then you might have to move the channels from left and
right to center (maybe aformat=cl=mono will suffice) take a look at the
-map_channel option, it might be simpler for you.

In my system (Linux Mint), the filter chain parameters for the '-filter_complex' directive *must* be
double-quoted.
