The online documentation is intended to be used with current git head
and is refreshed nightly. Users of releases and older versions should
refer to their local copy of the documentation.

If you want to add an example to the documentation the best method is to
retrieve the latest source code, make a patch with "git format-patch"
or "git send-email", and send it to the ffmpeg-devel mailing list
(ffmpeg-devel at ffmpeg.org).
