如何播放MemoryStrem Video C＃？ [英] How To Play MemoryStrem Video C# ?

问题描述

伙计们



我有大问题



如何在WinForms中从MemoryStream播放视频使用C＃



非常感谢

解决方案

如果您可以放弃要求从MemoryStream播放并且很开心要从文件中播放，您可以在表单ElementHost中使用WPF MediaElement：

 ElementHost host =  new  ElementHost （）; 
 MediaElementControl mediaElement =  new  MediaElementControl（）; 
 host.Child = mediaElement; 
  this  .Controls.Add（host）; 
 mediaElement.mediaPlayer.Source =  new  Uri（ @  C：\temp\delta.mpg）; 
 mediaElement.mediaPlayer.LoadedBehavior = System.Windows.Controls.MediaState.Manual; 
 mediaElement.mediaPlayer.Play（）; 

MediaElementControl.xaml

 <   usercontrol     x：class   =  WindowsFormsApplication2.MediaElementControl    xmlns：x   = ＃未知 >  
 xmlns =http://schemas.microsoft.com/winfx/2006/xaml/presentation
 xmlns：x =http://schemas.microsoft.com/winfx/2006/xaml
 xmlns：mc =http://schemas.openxmlformats.org/markup-compatibility/2006
 xmlns：d =http://schemas.microsoft.com/expression/blend/2008> 
 <   mediaelement    < span class =code-attribute> x：name   =  mediaPlayer    /  >  
 <   / usercontrol  >  

Hi ,Guys

I Have Big Problem

How Can Play Video From MemoryStream In WinForms Using C#

Thanks Alot

解决方案

If you can drop the requirement to play from MemoryStream and are happy to play it from file, you could use WPF MediaElement inside forms ElementHost:

ElementHost host = new ElementHost();
MediaElementControl mediaElement = new MediaElementControl();
host.Child = mediaElement;
this.Controls.Add(host);
mediaElement.mediaPlayer.Source = new Uri(@"c:\temp\delta.mpg");
mediaElement.mediaPlayer.LoadedBehavior = System.Windows.Controls.MediaState.Manual;
mediaElement.mediaPlayer.Play();

MediaElementControl.xaml

<usercontrol x:class="WindowsFormsApplication2.MediaElementControl" xmlns:x="#unknown">
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008">
<mediaelement x:name="mediaPlayer" />
</usercontrol>
