GPU usage restriction in specific app

I have two application running simultaneously.

  1. Camera Image Processing (Back-end)
  2. QT Interface with Video Playback

Here for camera processing I want full GPU utilization.
But when QT application plays video it also starts GPU use(I am using xvimagesink).

Is there any method to restrict GPU use to QT application(or any specific application)?

Hi,
You may refer to following page of controlling CPU/GPU frequencies:

However, it may not be possible to dedicate GPU cores to specific applications.
