libVLCSharp 无法创建 MediaList [英] libVLCSharp fail to create MediaList

问题描述

我正在玩 libVLCSharp，我发现了一个有线行为.实际上，我创建媒体并使用 MediaPlayer 播放没有问题.但是，当我尝试从 MediaList 创建媒体时，它会中断并显示以下消息:

I'am playing arround with libVLCSharp and I found a wired behavior. Actually I have no problem creating a media and playing it with MediaPlayer. However when I try to create a Media from MediaList it breaks with the followig message:

无法在本机端执行实例化.确保你在你的电脑中安装了正确的 VideoLAN.LibVLC.[YourPlatform] 包平台特定项目

Failed to perform instanciation on the native side. Make sure you installed the correct VideoLAN.LibVLC.[YourPlatform] package in your platform specific project

我想要实现的是使用 ":sout=#gather" 管道进行视频合并.

What I wanted to achive is video merging using ":sout=#gather" pipe.

我的代码非常基础:

Core.Initialize();

using (var libvlc = new LibVLC())
using (var mediaPlayer = new MediaPlayer(libvlc))
{
    Media media1 = new Media(libvlc, @"C:\Temp\SampleVideo.mp4");
    Media media2 = new Media(libvlc, @"C:\Temp\SampleVideo.mp4");
    MediaList list = new MediaList(libvlc);
    list.AddMedia(media1);
    list.AddMedia(media2);

    Media mediaList = new Media(list); <-- Error here

    ...
}

我的项目中使用了 2 个 nuget 包:

I have 2 nuget packages used in my project:

• LibVLCSharp v3.0.2 6 月 12 日
• VideoLAN.LibVLC.Windows v3.0.7 6 月 10 日

推荐答案

您希望为此使用 SetMedia，而不是 AddMedia.

You want to be using SetMedia for this, not AddMedia.

将媒体实例与此媒体列表实例相关联.

Associate media instance with this media list instance.

Core.Initialize();

using(var libVLC = new LibVLC())
{
    var media1 = new Media(libVLC, "https://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4", FromType.FromLocation);
    var mediaList = new MediaList(libVLC);
    mediaList.SetMedia(media1);
    var media2 = new Media(mediaList);
}
