Please show us the complete, uncut console output of that command. The
output contains information which is useful and not just there for the fun

Why ffmpeg 2.4.11? That should have decklink support, but it has
improved (extremely?) in recent versions. And I see no reason
whatsoever for choosing an old ffmpeg tree when compiling your own

Well, somebody is apparently not actually monitoring. 2.8.4 is latest,
and you might as well take HEAD of git master when compiling yourself.

There's a newer version of that available as well.
