Can you provide a link to the video that causes the problem? Also note that current ffmpeg version is 2.2. Please upgrade to that version and confirm that the problem still exists.
Thanks.

I simply can't. It's a pirated version of the first episode of Cosmos: A Spacetime Odyssey.
BTW I'm using the ffmpeg-devel port so it's pretty much up to date.

It's probably something else. This same issue happens when trying to play anything on mplayer with the SDL video-output driver. #43057

From your debug output it does look like a null pointer error in libsdl but I can't reproduce it here with any videos that I have tried using either ffmpeg-devel or mplayer-devel -vo sdl configured as you mention in #42906. Is this repeatable with any video that you try? Does mplayer-devel work correctly if you use the corevideo driver?

mplayer-devel and mplayer hanged with the CoreVideo driver, displaying a white screen with the correct video's aspect ratio and resolution, some audio can be heard at the beginning though.
BTW, I'm testing this on OS X 10.9.2

I've now tested on 10.9.2 and 10.8.5 using ffmpeg-devel and mplayer-devel and still cannot reproduce the problems cited here or in #42906 or #43057. Based on your debug output and other comments the problem does not seem to be ffmpeg or mplayer specific but has to do with libsdl itself as described in #43057. Therefore, I suggest switching this thread to #43057 and am marking this ticket as a duplicate.
The only remaining suggestion that I have is to rebuild libsdl from source to see if that makes any difference. Really a shot in the dark. Sorry for not being able to help more.
sudo port -ns upgrade --force libsdl
