OSX Lion: VTDecoderXPCService taking lots of CPU

For some reason, maybe showing those little videos for swiping and multi-touch, the Trackpad system preference pane invokes the VTDecoderXPCService and its uses lots of CPU.


So just don't leave the Prefs Pane on it.


Update: The VTDecoderXPCService is OSX Lion's video sandboxing layer, so you may get it using lots of CPU by doing other things as well.

In my case, I accidentally started (and left running) Photo Booth. Holy cow, that kept the machine drawing power, and the VTDecoderXPCService hitting a full core 100%.

Merci :-)
Photo Booth was heating up the computer.

I just had the same cpu issue on my late 2011 Mac Book Pro. I Forced Quit Face Time and this also killed the VTDprocess which in turn brought my cpu back down to earth.

same problem here. No programs open and the VTEncoderXPCService shows up. Any ideas?

Same here - El Capitan, VTDecoderXPCService using a ton of CPU. I know it's getting prompted by video ads on a website, but I have no idea how to stop this automated prompt from happening.

Seemed to be a case of me letting Adobe Flash get out of date, and as a result this service was then used to play videos instead of Flash. Loaded same web sites after Flash update and Safari re-start as before, and no issues with this service popping up again.
Safari 9.1.3, OSX 10.11.6.
