I have installed an Intensity Pro 4K capture card in my linux machine. So far all seems to work well, i can capture HDMI frames in my own applications. I noticed something unusual though: it can happen that DesktopVideoUpdater consumes 200% CPU and DesktopVideoHelper consumes 200% CPU. They seem to be busy spinning in a loop? Interestingly, when i launch Media Express, CPU consumption goes down to 100% each, and stays that way. After i kill these two processes, i can still use the decklink API.
Please look into this! Who wants two utilities taking up so much CPU?

I have the same issue here on Linux Manjaro 19.04. Both DesktopVideoUpdater and DesktopVideoHelper suddenly start randomly and eat all my CPU (around 400% too). Even when I kill them my capture card (a quad HDMI) is still working so there is no reason those two processes should start and eat that much CPU.
Otherwise the capture card is working wonderfully.
