Does anyone know what VTEncoderxpcservice is? Is it something my Macbook Pro needs to operate or an app? In my Activity Monitor it is using up to 170 % of my cpu. The processor gets very hot to the touch. Is this necessary?
MacBook Pro, Mac OS X (10.6.8)
If it is not a root function, what happens when you shut it down in Activity Monitor?
Ciao.
a quick search suggests that if it were spelled slightly differently, "VTDecoderxpcservice" is Lion and later's video sandboxing layer, so you may get it using lots of CPU by doing things such as Photo Booth or iMessage that require the camera. Shut those off and that usage disappears.
It's a background process that converts video in a photo or iMovie library. If an iOS device is connected, please disconnect it and see whether the activity stops.
My VTEncoderXPCService and VTDecoderXPCService runs between 150% to 300% and has already put 36 and 15 hours respectively of CPU time on my iMac in less than a day. I have no iOS device plugged in, however I do have photos in iCloud Photos library and a 49,000 song library in iTunes with iTunes Match turned on. Has the iMac been using these processes to optimize space for the Photos App on my little SSD (128 GB in optical bay) in which the OS X 10.11.2 resides? Might those processes be doing something else? (I can't tell how much disk or network activity are associated with those processes because they don't access the disk or network directly.) My iTunes library (iTunes Media folder is 411 GB) is on the 4TB WD Black HDD also inside my iMac.
This is on a 2009 iMac (Nehalem Core i7-860) so may this extra activity be due to Intel Quick Sync Video not being available because it's a pre-SandyBridge CPU? I have noticed people mentioning 2010 MacBook Pros and older Macs (all pre-SandyBridge) associated with this problem. In any case, I would like to know what the VTEncoderXPCService and VTDecoderXPCService are for, besides the obvious video encoding and decoding!
