I displayed the decoding stream two times,one is on multi-screen,and the other is on a single screen.The single screen display to get a better performance.The multi-screen display takes up more GPU.Whether multi screen display will affects the decoding performance by Intel Media SDK?Is there any way to improve?
I assume this is on the Windows OS.
This is basically the rendering issue which should not be caused by MSDK. The first you need to decide if this is caused by the platform itself--you can do the following test:
1. Launch an video/graphic application and let it render on 2 screen.
2. Find out if the GPU performance get increased.
Note: you should check both mirror mode and extend mode of the double screen.
