Comment (by thomas.c.jansen@…):

 I have to admit that I did not the same level of due diligence as you.
 However, I simply changed the “libsdl” to “libsdl2” in the port files (via
 “sudo port edit ffmpeg-devel”) and reinstalled ffmpeg-devel after that.

 Building worked fine, “port installed” does show “libsdl2” and _no_
 “libsdl" and “port deps ffmpeg-devel” shows..

 {{{
  $> port deps ffmpeg-devel
  Full Name: ffmpeg-devel @20140317_0+gpl2
  Build Dependencies:   pkgconfig, gmake, texi2html, yasm
  Library Dependencies: lame, libiconv, libvorbis, libopus, libogg,
 libtheora, libmodplug, schroedinger, libass, libbluray, gnutls,
 openjpeg15, fontconfig, freetype, speex, libvpx,
                        libsdl2, bzip2, zlib, XviD, x264

 However, otool doesn’t show a dependency to SDL on the ffmpeg binary at
 all — neither SDL1 nor SDL2! The same is true for the dylib's

 So, why does it require SDL?
