As an exception to the rule, I must say: Please google it!

You can find references in ffmpeg's docs for "unsafe file". And it has
been answered at least two times recently on this list. Most recently:

So, as Steven mentioned, "-safe" is the option to use. But it refers to
your inputs, so it must be placed before the input's "-i" in order to
work.
