I am trying to output a pipeline to the decklinksink with no luck.  The card
will only output black although the modes change correctly when selected. I
have tried filesrc and videotestsrc, with the same result: no error, just
black.

Example test: GST_DEBUG=4 gst-launch-1.0 videotestsrc pattern=smpte100 !
video/x-raw,format=UYVY,width=720, height=576, framerate=25/1,
interlaced=interleaved, pixel-aspect-ratio=12/11, colormetry=bt601,
chromasite=mpeg2 ! decklinksink mode=2

or: videotestsrc pattern=smpte100 ! videoconvert ! videoscale ! decklinksink
mode=2
