Anyone else seeing this in your Activity Monitor?
VTDecoderXPCService is running a full 25-30% of my CPU's on quadcore i7 iMac with 8GB RAM.
I have no apps running, yet the service is running like crazy..... any solutions?
OK... I finally discovered the source of the problem.
VTDecoderXPCService is the sandboxing for video content in Lion. All things that are QuickTime related, audio or video, are sandboxed by this service. It just clicked as to what it is. We have iCam for our iPhones. It allows us to remotely view from the webcams on our machines. So... because iCamSource is a QuickTime-related service, VTDecoderXPCService takes over. So when iCam is operating, it's sucking up 25% of the CPU. Which I'm going to report to the developer. :-)
Had the same issue with El Capitan (MacBook Pro late 2011). Found out that Evernote was using this process. Solved by quitting the Evernote app.
I have OS X El Capitan, I am only listening to music on YouTube. No special plug-in installed in Safari. Everything is deactivate in the System Preferences. VTDecoderXPCService and Quicktime ?
your step solved my issue!
thank you!
To Doug, so does this mean you actually DID have this iCamSource app running, only you didn't notice it?
I had this issue while watching HD podcasts in iTunes in PiP mode on Sierra. Simply restarting iTunes has solved the issue ... for now at least!
On my machine what was causing high CPU usage was Photos in icloud being logged in and constantly syncing. Go into icloud in settings of your mac and untick the box for photos.
Thanks, quitting the process fixed this for me, too. But I wonder what is triggering it to begin with? For me it opening mail seems to trigger it.
