Description

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,
