Comment (by BenjaminG):

 I've tested on Linux and MacOS
 For MacOS :

 {{{
 port install libopenjpeg
 export CFLAGS="-I/opt/local/include/"
 export LDFLAGS="-L/opt//local/lib/"
 ./configure --enable-libopenjpeg --prefix=/your/path/of/ffmpeg/
 make
 }}}

 }}}

 Playing...

 Works with lowres 1 to 3.
 I see some freeze in some DCP

 In attachment, 2 outputs display.
 First: DCP Test from Eclair Laboratoires
 Second: DCP Terminator Salvation.

 Colorspace seems to be good for me (I should do this test on a DCP2000
 player when it's possible).
