Windows 10: Not working h/w acceleration for WPF app. over RDP

When I use WPF application over RDP, .NET using only CPU instead GPU for processing DirectX: https://github.com/dotnet/wpf/issues/3215

Windows 10 getting HEVC H.265 Codec to use Hardware Acceleration

Playing HEVC H.265 videos using Windows Media Player and GoPro Quik then the 4k 60 fps video appears all stuttering and becomes a slideshow. The CPU usage is going through the roof and it's not using Hardware Acceleration. I have installed the "HEVC Video Extensions" from Microsoft Store. When I use the app "Movies & TV" for playing the video file then it uses around 1% CPU and Hardware Acceleration seems to be enabled.

How can I get Windows Media Player and GoPro Quik to use Hardware Acceleration?

"HEVC Video Extensions from Device Manufacturer" (Free version that works with licence software like GoPro Quik): https://www.microsoft.com/en-us/store/p/hevc-video-extension/9n4wgh0z6vhq

I have tried following:

1. Uninstall all codecs, also the "HEVC Video Extensions" from Store: Windows Media Player plays only the sound, screen is black. Unable to open video in GoPro Quik
   
2. Installed K-Lite Codec Pack (w/HEVC codec): Windows Media Player plays the video with both video and audio smoothly. The playback is hardware accelerated as it only used 1% CPU. Unable to open video in GoPro Quik
   
3. Install "HEVC Video Extensions" from store (Regardless if K-Lite is installed or not): Windows Media Player plays video with both video and audio but it's stuttering. Playback is not hardware accelerated and it uses near 100% CPU. GoPro Quik is now able to open and edit the video but it's stuttering, using 100% CPU on playback and hard to edit the movie
   

System specifications:

• Windows 10 Pro N, Version 1803, OS Build 17134.165
  
• Intel i7-8700K @ 3.7Ghz (8th gen, coffee lake, newer then Kaby Lake)
  
• 16 GB Ram
  
• Nvidia GeForce 1070 GTX (Driver version 398.82 which is the newest)
  

One solution would be using software like Handbrake to convert the video file from H.265 to H.264, but I consider that a "hack" as this really should work with my system spec.

 

Notifications not showing from WPF app

I'm having trouble seeing toast notifications from a WPF app that I've built in Visual Studio 2017. About a month or so ago, these notifications were working fine. I had already gone into the Windows settings and enabled the notifications for this app.
However, my app is no longer in the list of applications that can have notifications enabled or disabled. I'm not sure how to go about fixing this. How do I make them come back?

 

Enable visual styles in WPF application

EUREKA!

Steps:
1) I made a Windows form (HostWPF namespace, Form1 is the form).
2) I added a reference => System.Windows.Forms.Integration which contains classes that enable interoperation between the Windows Forms and WPF technologies. When you use System.Windows.Forms.Integration classes, you can host Windows Forms controls on WPF pages, and WPF elements in Windows Forms-based applications.
3) Then added a control (damn Vi$ual $tudio 2010 does not allow to add a WPF window) but after adding I edited the XMAL code in the way I want *Wink
4) The next steps are simple. Download the first attachment. But => see the photo.
It crashes!!!!!
5) Finally???
We must use System.Windows.Forms.Application.Exit(); command because the WPF window behaves like a classical Windows Form.
Download the second attachment. Note that the Windows form's name is Initial.
Enjoy!
