macOS – VTDecoderXPCService high CPU Usage

I noticed high CPU usage under macOS from a service called “VTDecoderXPCService” and I didnt know what was the cause, so I looked for a way to finde it.

  1. Go to the “Activity Manager” and select the “VTDecoderXPCService” Process, then click on the gear icon and select “Spindump”bildschirmfoto-2016-10-31-um-10-42-20
  2. Wait for about 10 seconds until you see the the Spindump.bildschirmfoto-2016-10-31-um-10-40-39
  3. In the Spindump window under “Responsible” you can find the Process which started the “VTDecoderXPCService” Process. (In my case it was a HTML5 Website with embedded video…)

This solution could be used for all Processes, not just for the “VTDecoderXPCService”
