How to display a video in the window from the path embedded in the program in C# WPF?

In the C# program, I want to display and play a video from within my program in a window.

The path that I give to my video source as an internal path of the embed type works in design mode, but it does not display the video when running the program, but if I give it the direct address of the file in Windows, it works.

This is despite the fact that if I want to show a photo or gif from the same path, it works and shows well

What I need :

In C# WPF on Visual studio 2019 in Windows 10, I want to show and play a video inside a My window from the app not directly path

What have I done :

I have included that video in my project, then I set the path for the video and it shows it to me in design view! :

What have I tried and my code :

so I decided to try it in three-way, also to try to show a gif for sure about the path.

Embedded path
Normal Path
Direct path on windows
but only the direct path works! While the same embedded path works for GIF

MyGIF : Source="pack://application:,,,/Medias/1Correctmation.gif" => works fine

My Video : Source="pack://application:,,,/Medias/Video1.mp4" => not working

My Video : Source="C:\Users\user\Desktop\Video1.mp4" => workis fine but I don't want this directly path

also for my video file I tried these BuildAction:

Embedded
Resource
Content Resource
none of them work.
