Comment:

 Status:

 In addition to the sdl outdev, the bundled utility ffplay also uses libSDL
 as its output device.  However, after applying the following configuration
 items
 {{{
 --disable-outdev=sdl
 --disable-ffplay
 }}}

 the sdl outdev and ffplay are, indeed, disabled but configure still
 detects libsdl if it is installed and the various libraries link with it.

 So it appears that there is no way to definitively disable references to
 libsdl other than it not being installed.  Since we can't guarantee this
 in MacPorts, I'm afraid there's not much further to be done without some
 major hacking of the code.

 I'm attaching my working patch to the current ffmpeg port in case you'd
 like to play with this yourself on your local port.

 I also note that a [https://trac.ffmpeg.org/ticket/3604 ticket has been
 opened upstream requesting SDL2 support].

 Closing as won't fix for now.
