Th input file index is explained e.g. in this chapter:
https://ffmpeg.org/ffmpeg.html#toc-Advanced-options

Basically, for your first (or only) input, use "0" (but that's the
default, apparently). Or higher numbers for your further inputs.

If you only have one input, and chapters aren't being mapped, then
something else is not working.
