DesktopVideoUpdater and DesktopVideoHelper consume 400% CPU

PostSat Mar 14, 2020 8:15 pm

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?

Hello,

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.

Exactly same behaviour here: full CPU usage after suspend to RAM.

Setup: Linux Mint 19 Tara 64-bit (equivalent to Ubuntu Bionic), kernel 4.15.0-109-generic x86_64, DeckLink Duo 2 running firmware version 11.5.1.

Same here, consuming 100-200% of 12 processors while DR is not running!!!

Has anyone found a way to stop this? Seems like an excessive amount of updating on a system that isn't running.
