XNA VideoPlayer对象导致“ CrossThreadMessagingException” [英] XNA VideoPlayer object causes 'CrossThreadMessagingException'

问题描述

（关于我之前的问题：播放视频（MSDN教程））

我遇到以下问题：当我尝试读取XNA VideoPlayer对象的状态时，出现了 CrossThreadMessagingException 。意思是，我正在尝试从其他线程中读取内容。

关于如何解决此问题的任何想法？ （是否有办法告诉VideoPlayer对象在缓冲区中写入内容？）

代码：

 受保护的重写void Update（GameTime gameTime）
 {
 //如果（GamePad.GetState（PlayerIndex.One）.Buttons，允许游戏退出
 .Back == ButtonState.Pressed）
 this.Exit（）; 
 
 if（player.State == MediaState.Stopped）//导致异常
 {
 player.IsLooped = true; 
 player.Play（视频）; //导致神秘的崩溃
} 
 
 // ... 
} 
  

错误消息：

player.State ='player.State'抛出了

类型的例外

'Microsoft。 VisualStudio.Debugger.Runtime.CrossThreadMessagingException'

解决方案

是的，显然不是他有这个问题，因为我也有同样的问题，可以在我的计算机上正常工作，可以连接到360和 BANG， CRASH， BOOM。我正在其他论坛上进行研究，并在寻找答案时找到了它。

(Relating to an earlier question of mine: Playing a Video (MSDN Tutorial))

I have the following problem: When I'm trying to read the state of a XNA VideoPlayer object I get an CrossThreadMessagingException. Meaning, I'm trying to read from a different thread. This seems to be not allowed (I have no idea how threads work in C# internally :-)

Any ideas on how to fix this? (Is there a way to tell the VideoPlayer object to write in a buffer or something?)

Code:

protected override void Update(GameTime gameTime)
{
    // Allows the game to exit
    if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
        this.Exit();

    if (player.State == MediaState.Stopped)  //Causes the exception
    {
        player.IsLooped = true;
        player.Play(video); //Causes the "mysterious" crash
    }

    // ...
}

Error Message:

player.State = 'player.State' threw an
exception of type
'Microsoft.VisualStudio.Debugger.Runtime.CrossThreadMessagingException'

解决方案

Yeah well it's apparently not just this him having the issue as I have the exact same problem , works fine on my computer, port to the 360 and "BANG" "CRASH" "BOOM". I'm working on it in other forums and found this while searching for an answer.
