I moved the option that is obviously needed for the auto-detecting demuxers.

The original issue was that the image2pipe demuxer happily accepts
"loop" but ignores it - confusing users, I wonder if the only solution is
to split the options between image2pipe and the auto-detecting
demuxers or if there is another solution (or if both patches should
be reverted).

Sorry, Carl Eugen
