Description

Hi all,

I have successfully compiled ffmpeg with Decklink SDK 10.9.5 and up to date ffmpeg repo with --enable-decklink option.

When I run :

ffmpeg -format_code Hi50 -f decklink -i 'UltraStudio Mini Recorder' out.ts

I receive this error :

I cannot even re-compile ffmpeg N-86620-g3594788b71 which was working before..

I think I have other errors somewhere :/

I ran otool -L on both bin (working and broken). Do you think those difference of library version can create those kind of bug ?

Please test ./configure --enable-nonfree --enable-decklink

./configure --enable-nonfree --enable-decklink --extra-cflags=-I/Users/Sylvain/Scripts/Blackmagic_SDK_10.9.3/Mac/include/ --extra-ldflags=-L/Users/Sylvain/Scripts/Blackmagic_SDK_10.9.3/Mac/include/

I've read somwhere that I should put static at the beginning of line 56, 77 and 157. It was working before but now I cannot reproduce the compilation. Maybe it's not a good way to resolve this.

Thanks.
