VTDecoderXPCService taking upwards of 400% CPU

On startup & randomly while working/watching stuff on my computer, the fans will start to get really, really loud. I keep seeing "VTDecoderXPCService" showing up & taking up to 600% of my CPU. I've tried resetting the NVRAM & quitting the process but the problem is still occurring. I'm worried it will damage not only the fans but the battery as well since it's heating up a lot while the fans are extremely loud. Any idea on what could be wrong or what I can do?

MacBook Pro with Retina display, macOS High Sierra (10.13.4)

Hey kvnzrt,

If I understand correctly, there is a process that begins running and has a very high CPU percentage. If this happens after the computer starts, it could be a login item. Removing it as a login item will prevent it from starting randomly.

Add and Remove

To have an item open automatically at login, click the Add button on the right, then select the item.

To stop an item from opening automatically, select the name of the item, then click the Remove button on the right.

macOS Sierra: Login Items pane of Users & Groups System Preferences

Thank you for using Apple Support Communities. Have a good one.

That process will run every time there is decoding and rendering going on. You can quit some apps that you have running, restart and see if it is better.
