Integrate VLC player in C# (WPF) project using Vlc.DotNet

I want to integrate to my project a VLC player to display video cameras streams. For that, I try to use Vlc.DotNet (2.1.126 version) in my WPF project.

Answer 1

The WPF version of the VlcControl is just a WindowsFormsHost control hosting the Windows Forms version of the VlcControl. Judging by the error message (The value of type "VlcControl" cannot be added to a collection or dictionary of type 'UIElementCollection') you're simply missing a reference to the WindowsFormsIntegration assembly, in which the WindowsFormsHost is defined (it can be found under Assemblies → Framework in the reference manager).

Here's a fully working example of a WPF window hosting the VLC player. You need to install the Vlc.DotNet.Wpf NuGet package (and its dependencies) and reference the WindowsFormsIntegration assembly.

MainWindow.xaml

<Window x:Class="HelloVlc.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:vlc="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf">
    <vlc:VlcControl x:Name="vlcPlayer" />
</Window>

MainWindow.xaml.cs

public partial class MainWindow
{
    public MainWindow()
    {
        InitializeComponent();
        vlcPlayer.MediaPlayer.VlcLibDirectory =
            //replace this path with an appropriate one
            new DirectoryInfo(@"c:\Program Files (x86)\VideoLAN\VLC\");
        vlcPlayer.MediaPlayer.EndInit();
        vlcPlayer.MediaPlayer.Play(new Uri("http://download.blender.org/peach/" +
            "bigbuckbunny_movies/big_buck_bunny_480p_surround-fix.avi"));
    }
}
