c# - Dll未找到异常 : Unable to load DLL 'libvlc' : The specified module could not be found

Question

我正在使用 LibVLCSharp(Vlc nuget 包)设置视频播放器。我已经安装了VideoLAN.LibVLC.Windows和 LibVLCSharp.WPF到目前为止，在我编译和运行我的代码之前一切看起来都很好。

我的 VideoPlayer.xaml.cs 文件是这样的:

using LibVLCSharp.Shared;

using System.Windows;
using System.Windows.Controls;
using System.Windows.Media;
using MediaPlayer = LibVLCSharp.Shared.MediaPlayer;

namespace kec_wpf.ui
{
    public partial class VideoPlayer : Window
    {
        LibVLC _libVLC;
        MediaPlayer _mediaPlayer;

        public VideoPlayer()
        {
            InitializeComponent();

            var label = new Label
            {
                Content = "TEST",
                HorizontalAlignment = HorizontalAlignment.Right,
                VerticalAlignment = VerticalAlignment.Bottom,
                Foreground = new SolidColorBrush(Colors.Red)
            };
            test.Children.Add(label);

            _libVLC = new LibVLC();
            _mediaPlayer = new MediaPlayer(_libVLC);

            // we need the VideoView to be fully loaded before setting a MediaPlayer on it.
            VideoView.Loaded += (sender, e) => VideoView.MediaPlayer = _mediaPlayer;
        }

        void StopButton_Click(object sender, RoutedEventArgs e)
        {
            if (VideoView.MediaPlayer.IsPlaying)
            {
                VideoView.MediaPlayer.Stop();
            }
        }

        void PlayButton_Click(object sender, RoutedEventArgs e)
        {
            if (!VideoView.MediaPlayer.IsPlaying)
            {
                //VlcControl.SourceProvider.MediaPlayer.Play(new Uri("pack://siteoforigin:,,,/assets/content/" + Title + ".mp4"));
                VideoView.MediaPlayer.Play(new Media(_libVLC,
                    "http://www.quirksmode.org/html5/videos/big_buck_bunny.mp4", FromType.FromLocation));
            }
        }
    }
}

但是我在构建和运行时得到的错误是:

DllNotFoundException: Unable to load DLL 'libvlc': The specified module could not be found. (Exception from HRESULT: 0x8007007E)

我不知道如何解决这个问题，因为在 bin/debug 文件夹中我看到一个名为“libvlc”的文件夹，里面有文件夹“win-x64”和“win-x86”。

我的临时解决方案:

1. 在 Project 中将我的程序设置为 x32 >> Properties
2. 将 libvlc.dll 和 libvlccore.dll 以及 lua、语言环境、插件和皮肤的整个文件夹复制到我的调试文件夹中。

这目前有效，但我需要一个实用的解决方案，因为我在项目中已经有了 VideoLAN.LibVLC.Windows。

您是否忘记调用 Core.Initialize()？
