I try to find the option for selecting the audio channels I want to have, but to no prevail.

-c is the option for the setup file.

According to ffx264 -h there is no such option as -ac. -ac is not to be found in the man page either.

What do I miss here?

Do I need to create a setup file for each DVD to get the audio tracks that I want?

-ac is used internally by the channel code itself to set the channels desired by the user. I made a change to that code that I left and didn't revert. There's no -ac parameter in the ffx264 options

You don't need to set up any setup/config files. Just pass through the script and answer the questions

Ahh good to know.

One issue remains. It aborts with an error:

-> MPlayer is missing from your system!

I don't have mplayer but mpv installed in my system.

Can mpv used instead of mplayer?

If not and if I do not want any crop, how can ffx264 be convinced to run without mplayer?
I do not see an option to disable crop.

When I understand it correctly, ffx264 as well as fhevc and ffxvid all use mplayer for crop, so when one not uses crop all scripts should be able to work without mplayer.

Set AUTOCROP to "n" in the config file located in $HOME/.ffx264 (a hidden file)

MPlayer is a requirement, though. It is used only for crop preview, not crop itself which uses FFmpeg. I'll make it optional in another release shortly

I will not switch to mpv as someone else can come and say he has MPlayer installed but not mpv. I've chosen MPlayer for crop preview because it has the rectangle filter. I do not know if mpv has it too, for that matter

mpv have if you have not know all ffmpeg filters, thus it have drawbox filter which is much more powerful than rudimentary and unmaintained mplayer filter.
