Microsoft.Xna.Framework.Media（Monogame）中 VideoPlayer 上的 Microsoft.Xna.Framework.Content.ContentLoadException

Question

我正在尝试在 Monogame 中播放视频。我遇到了一些麻烦，因为最简单的方法是使用 VideoPlayer，由于某种原因它不在我的 Microsoft.Xna.Framework.Media 中。所以我将我的 visual studio 项目指向引用 Microsoft.Xna.Framework.Video.dll 并且我能够很好地制作 VideoPlayer 的对象。

我的示例代码如下：

videoPlayer = new VideoPlayer();
video = content.Load<Video>("Intro_Videos/main_intro");
videoPlayer.Play(video);

我在第 2 行遇到错误，

Microsoft.Xna.Framework.Content.ContentLoadException: 'Could not find ContentTypeReader Type. Please ensure the name of the Assembly that contains the Type matches the assembly in the full type name: Microsoft.Xna.Framework.Content.VideoReader (Microsoft.Xna.Framework.Content.VideoReader)'

下面更详细的错误：

Microsoft.Xna.Framework.Content.ContentLoadException
  HResult=0x80131500
  Message=Could not find ContentTypeReader Type. Please ensure the name of the Assembly that contains the Type matches the assembly in the full type name: Microsoft.Xna.Framework.Content.VideoReader (Microsoft.Xna.Framework.Content.VideoReader)

   at Microsoft.Xna.Framework.Game.Run()
   at Program.<Main>$(String[] args) in C:\Users\garre\Desktop\Devcade\Devcade-Hero\Program.cs:line 3

更多的上下文是路径应该是正确的。该视频是一个 .mp4，并且该项目使用资产构建得很好。我在 x86（主动解决方案平台）上构建。

如有任何帮助，我们将不胜感激。

VideoPlayer 已在 Monogame 中删除，引用 Microsoft.Xna.Framework.Video 与 Monogame 不兼容。
