You should try the latest ffmpeg git master, RGB support just got recently 
committed, and if you are capturing from HDMI maybe you have to use an RGB 
format. Until now, ffmpeg always requested YUV, and I am not sure if 
decklink is supposed to do a software conversion by default or not.

You wrote a very long letter by the way, try to be more laconic.
