decklinksrc pipeline optimization

[wunwunforever]

I am facing the same issue with an UltraStudio HD Mini and I'm unsure it is
caused by a lack of system resources.


runs successfully, utilising ~13% CPU monitored by htop, on an 8 core
MacbookPro with no cores maxing out.


is unsuccessful, constantly logging
gstdecklinkvideosrc.cpp:897:gst_decklink_video_src_got_frame:<decklinkvideosrc0>
Dropped 1 old frames from X to X

And the output gets stuck on the first frame.

I have tried changing CPU priority:
 - The first pipeline with minimum priority still runs smoothly.
 - The second pipeline with maximum priority still drops frames.

Is there something else I need to increase to allow it to use more system
resources?
