 Hi all,

 First ticket here, sorry if incomplete.

 I try to compile ffmpeg on MacOS with the --enable-decklink option :

 {{{
 ./configure --prefix=/usr/local --enable-gpl --enable-nonfree --enable-
 libass --enable-libfdk-aac --enable-libfreetype --enable-libtheora
 --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265
 --enable-libopus --enable-libxvid --enable-decklink --extra-
 cflags=-I/usr/local/include/ --extra-ldflags=-L/usr/local/lib/
 }}}


 configure script is OK but fail when I make :

 {{{
 libavdevice/decklink_dec.cpp:265:10: error: no previous prototype for
 function 'vanc_to_cc' [-Werror,-Wmissing-prototypes]

 I have succeed to do it before (June 2017) so I think it's a regression.

 Thank for your help,
