6th Gen Intel NUC - Windows 10 - 4k Video Playback

We are trying to get 4K video displaying on our 6th NUCs.

When playing a video via the native Windows video player the CPU does not go over 50% whilst the video is playing. 

When a video presentation is playing via Rise Vision player, the CPU sits at 90% and above, and the video is very choppy.

Any tips on how to get 4k videos displaying nicely or whether this is even possible?

6th Gen Nuc
8 GB Ram
120GB .m2 SSD
Latest display drivers installed from intel site

As a side note I have tried Ubuntu also but had no luck finding any display drivers for the NUC - would be happy (really happy) if there are any answers on the Ubuntu side of things.

Hi Arnie
Could you check to see if your video drivers are properly installed? As this could contribute to the high CPU. See this SO for a reference.

Hi there,

This particular problem is based on a Windows 10 install, for which I have installed the following drivers:

In the Device Manager  in Windows I can see that it has recognised the Intel HD 520 chipset, and when looking at the properties the driver version and provider all line up with what has been installed.

Is there anything else I should check to verify this is installed properly?

When testing a 4K video using the native Windows Video Player the video plays back very smoothly and CPU does not go up very much at all - it peaks at under 50%.

When the same video is played through a rise vision presentation it is choppy and CPU is up at a constant 90% to 95%.

Is there a particular format, or codec that RiseVision needs in order to use hardware acceleration?

Is there something I should check from the configuration of the presentation is concerned?

Best Regards,
Don't test the video in WMP. Test it in Chrome. You can open a local video file in Chrome by just dragging the file. Then you can use Chrome's task manager to view the CPU usage of the tab playing the video. Since Rise uses Chromium it will give you a better idea of what will work on the display.

I've been doing some testing for my signs and Chrome seems to prefer h264 on my Intel Compute Stick. It shows a CPU usage of ~3% for the video tab vs 15-30% when playing the same video encoded with VP8.

I suggest you see how your video is encoded and if it isn't h264 try re encoding it to see if that has a performance impact.

Great point Chris! Arnie,

Can you let us know if a re-encode helps the issue?
