WPF Media Element Video Source

Question

I try to set video source in XAML code, video doesn't play:

<MediaElement x:Name="bgvideo" Width="800" Height="600"Source="/Videos/BG_LOOP_BIG.wmv" />

So I try to set video source in codebehind, that doesn't play too. :

bgvideo.Source = new Uri(@"pack://application:,,,/Videos/BG_LOOP_BIG.wmv", UriKind.Absolute);

or

bgvideo.Source = new Uri(@"/Videos/BG_LOOP_BIG.wmv");

It just play when video source is absoulte:

bgvideo.Source = new Uri(@"C:\SomeFolder\Videos\BG_LOOP_BIG.wmv");

How can I set video source with relative source?

Solution 1

This works for me. Add LoadedBehavior="Manual"

<MediaElement LoadedBehavior="Manual" x:Name="bgvideo" Width="800" Height="600" Source="Videos/BG_LOOP_BIG.wmv" />

Then in the code behind you need to play the media

bgvideo.Play()

You also need to lose the first '/' in the uri.

Solution 2

<MediaElement x:Name="bgvideo" Width="800" Height="600"Source="Videos/BG_LOOP_BIG.wmv" />

This is also working, you just have to set the property Copy to output directory of the video file on copy if newer or copy always.

Solution 3

Drop the first slash:

:)

also, as far as I know, Videos cannot be embedded into the assembly.

I already try this issue : I set LoadedBehavior="Manual" and Loaded event with "bgvideo_Loaded" event handler. I wrote bgvideo.Play() in bgvideo_Loaded method. Now; I removed first '/' and still not working :(

Have you got the wmv in bin/debug/Videos/? If you remove the LoadedBehavior attribute it should start playing automatically without the need to call Play().

There is no Video folder in bin/debug :) I copied that, and it works :) Thank you so much. Why visual studio doesn't copy this folder in bin/debug, do you have any idea?

If you add a 'Video' folder to the project then pop your video in there and set it's 'Copy to Output' property to 'copy' it'll copy it down to the output folder for you.

damn. had the same issu since now 2 hours. First I thought it was the codec. When removing first "/" slash Visual Studio 2010 says: error, is not part of the project. But it just works perfect now. Just remove first "/" was my secret. thanks to your post!
