带有帧访问权限的wpf视频 [英] Video in wpf with frame access

问题描述

你好，



我一直在努力在谷歌上回答这个问题。



我想创建ac＃wpf应用程序来播放视频avi文件。我想访问每个视频帧进行一些图像处理。



从我所看到的，c＃中没有本地控制来执行此操作（使用。 net 4）。



人们说应该可以使用DirectX和XNA。我一直在玩XNA，但在wpf应用程序中找不到任何播放视频的说明。



我想要的是有人指点我正确的方向？





亲切的问候....

Hello,

I''ve been struggling to answer this on Google.

I would like to create a c# wpf application to play video avi files. I would like to get access to each video frame to do some image processing.

From what I can see there is no native control in c# to do this (using .net 4).

People say that it should be possible with DirectX and XNA. I have been playing around with XNA but can''t find any instructions for playing video in a wpf application.

What I would like is someone to point me in the right direction?


Kind regards....

John

推荐答案

你可以在WPF中使用winforms控件，所以我想你想创建一个使用DX来做你想做的控件，然后插入就这样。我发现使用这些控件可以创建渲染问题，我这样做是为了导入winforms windows媒体播放器控件，因为WPF中的视频支持有多糟糕（这真的很糟糕，而且我不是'尝试做任何你想做的事情都很复杂。



WPF是DirectX，所以我希望有办法创建直接使用DirectX的东西，中间没有winforms图层。

You can use a winforms control in WPF, so I''d think you want to create a control that uses DX to do what you want, and then insert it that way. I''ve found that using those sort of controls can create rendering issues, I did that to import a winforms windows media player control, because of how bad the video support is in WPF ( it''s truly awful, and I wasn''t trying to do anything as complex as what you want to do ).

WPF IS DirectX though, so I''d have hoped there would be a way to create something that uses DirectX directly, without a winforms layer in the middle.
