1 c# vlc visual-studio libvlcsharp
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: 无法加载 DLL 'libvlc': 找不到指定的模块。(来自 HRESULT 的异常: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,其中包含“win-x64”和“win-x86”文件夹。
我的临时解决方案:
Project>>中将我的程序设置为 x32Propertieslibvlc.dll和libvlccore.dll与卢阿,区域设置,插件和皮肤对我debug文件夹中的所有文件夹。这现在有效,但我需要一个务实的解决方案,因为我VideoLAN.LibVLC.Windows已经在项目中了。
你忘记调用 Core.Initialize() 了吗?
