Just downloaded VLC version 2.1 and noticed the following line in the changelog:
New output for Decklink Blackmagic cards
This feature is also listed on the release page.
This got me pretty excited as I've been waiting for this to happen for a while, but I can not for the life of me figure out how to get this working. I've been hunting through menus and preference pages for a while but I can't seem to find anything pertaing to Blackmagic Decklink cards. I would really like to have VLC play video through my Decklink Intensity Pro card. Is this possible?
