getting gstreamer 1.0 to work with decklinksink

[Mitchell Foley]

After a bunch of messing around with my system, I was able to get
everything to compile from git. I think it had something to do with having
multiple versions of orc installed somehow. However, my simple
pipeline of gst-launch-1.0
videotestsrc ! decklinksink still doesn't display any output. It doesn't
crash, but it doesn't display anything either.

Any ideas what I should try next?

Thanks,

-Mitch
