Has anybody tested and reported back success (no issues) with the recent
decklink and rgb support added? In particular rgb10 mode.
I've have good luck in capturing from my 'DeckLink Studio 4K' only when
RGB (can't seem to capture YUV, perhaps the HDMI data is only RGB --
still need to do testing with known YUV over HDMI as well)
-raw_format argb (and bgra) work and fairly well I will add!
-raw_format rgb10 does wierd things
(Sorry in advance for the long post, took most of the information out
because I was told to not be soooo long)

(ffmpeg10 is ffmpeg pointing at libx264-10-bit version)
FWIW, it seem the output file (x264-10.mov in the example above) is
okay, but haven't tested enough to make sure it isn't dropping actually
dropping frames (I know it's confused between 600.0fps and 60000/1001
[59.94]).
