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

Mojtaba_Hakim 281

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

You could try pack://siteoforigin instead of pack://application in your Source path. Btw I found this out because there's a MediaFailed event that you can add a listener to on your MediaElement which will tell you the problem.

MediaElement silently fails when loading its source so it's best to listen for that error & at least log it to your debug console.

Try changing the Source of your <MediaElement> to start with pack://siteoforigin:

But generally you can also add a MediaFailed event handler to be alerted if your media fails for any reason. If you click on your <MediaElement> in Design view, click the events button (lightning bolt above the Properties panel), then double-click the "MediaFailed" event type:

Then you can add an event handler to Debug.WriteLine the error message if it occurs:

private void TestVideo_MediaFailed_1(object sender, ExceptionRoutedEventArgs e) { var details = $"Failed to load media: {e.ErrorException.Message}"; Debug.WriteLine(details); MessageBox.Show(details); }

This can give you an idea of whether your <MediaElement> failed to load.

Ah, if you set Build Action to None instead of Resource then it should work.

Hi,
please, use correct Uri (without slash):

 <MediaElement Stretch="Fill" Source="Medias/Video1.mp4" />

  <MediaElement Stretch="Fill" Source="pack://siteoforigin:,,,/Medias/Video1.mp4"/>

folder "Medias" in your project;
file "Video1.mp4" in this folder;
properties: Content and Copy always or if newer
