Sounds like, you have defined source of video. With it, you can play video:
1. WPF app using MediaElement

HTML

<MediaElement Source="http://yourwebsite/yourvideo.mp4" LoadedBehavior="Manual" Name="mePlayer" />

Refer:Playing video - The complete WPF tutorial[^]

2. HTML5 using video tag

HTML

<video width="320" height="240" controls="">
  <source src="url-to-video.mp4" type="video/mp4"></source>
</video>

try out!

Hi I use the link you share. the link in that example work when I use in my program and video run after the load enough buffer data.
But when i use my Own URL or random video link from another site the program show the below error.
"System.NullReferenceException: Object reference not set to an instance of an object"
my video in mp4.
what should I do?

Details about the error you see: NullReferenceException Class (System) | Microsoft Docs[^]
Quote:A NullReferenceException exception is thrown when you try to access a member on a type whose value is null
Possibly because:
1. You've forgotten to instantiate a reference type
2. You've forgotten to dimension an array before initializing it.
3. You get a null return value from a method, and then call a method on the returned type.
4. You're using an expression (for example, you're chaining a list of methods or properties together) to retrieve a value
5. You're enumerating the elements of an array that contains reference types, and your attempt to process one of the elements throws
6. Exception is thrown by a method that is passed null

When you debug, you will be able to get the exact line where the variable is NULL and error is being raised.

my code for this part is:
if (mediaelement.Source != null)
{
mediaelement.Play();
}
the error occur in the mediaelement.play(); line

Sounds like your mediaelement is null. DEBUG please.

I DEBUG my project. when I set the example url in the XAML OR C# Code. the video is running.

mediaelement.Source = new Uri("http://hubblesource.stsci.edu/sources/video/clips/details/images/hst_1.mpg");

But when i use the another video link (for Mp4 type) on both way. the program show the above error.
