Cannot destroy ofxBlackmagic object

[acastles91]

Hello. I am trying to make a program that uses the feed from a decklink card but then at some point it closes it and opens ffmpeg to capture from it externally. However, the .close() method doesn't kill the camera and leave it available for ffmpeg, and if I define it as a shared pointer and try to delete it before calling ffmpeg I get a segmentation fault. Do you know where the problem might be?
