[FFmpeg-user] image2 examples missing `-f image2`, can that be right?

You were unable to convince me that an improvement is possible and
makes sense (would actually improve the documentation as opposed
to just make it longer).

You have now two possibilities:
Either send a patch (made with "git format-patch") that contains your
suggested improvements to the documentation to the development
mailing list or we continue here to discuss that 1) the image2 demuxer
does not support nearly all formats supported by FFmpeg but we
cannot mention them all, 2) it is not true that "'%d' usually implies
image2" (it never does, contrary to what was claimed in this thread)
and 3) you request an additional example but you failed to provide a
usecase that needs it (I know that an infinite number exists but since
you provided only a use-case for not using the image2 demuxer it
appears to me that an additional example - that by definition makes
the documentation longer and therefore less readable - would not
have helped you.
