如何在播放视频文件上放置透明的图片框？ [英] How can you place a transparent picturebox over a playing video file?

问题描述

是否有一种简单的方法可以在播放的视频上放置透明的图片框？



此时我宁愿在同一张表格上进行此操作。我想做什么

显示视频，并在视频上放置一个图片框。



必须有可能但经过一天的尝试后我有点卡住了吗？即使是关于如何执行此操作的

链接也将非常感激。

Is there an easy way to place a transparent picture box over a playing video?

At this point I would rather do it on the same form. What I am trying to do
is display the video, and place a picture box frame over the video.

It must be possible but after a day of trying I am a little stuck? Even a
link on how to do this would be greatly appreciated.

推荐答案

一个非常简短的答案：作为GDI和DirectX（用于显示视频）不能很好地生活在一起，这可以被认为是一个太困难的问题。您需要使用带有 System.Windows.Forms 的DirectX overlay 。例如，参见：

怎么办？我的建议是：不要到那儿，而是切换到WPF ，这本身就是基于DirectX。



WPF中的所有内容都可以半透明，所有内容都可以覆盖所有内容，包括视频，无需任何特别的努力。我测试了它;这很容易。

A very short answer: as GDI and DirectX (used to show video) don''t live well together, this can be considered to be a too difficult problem to bother. You would need to use DirectX overlay with System.Windows.Forms. See, for example:
http://www.unknowncheats.me/forum/c/62019-c-non-hooked-external-directx-overlay.html[^],
http://gregs-blog.com/2008/02/26/managed-directx-c-graphics-tutorial-1-getting-started/[^].

What to do? My advice is: don''t get there, instead, switch to WPF, which is itself based on DirectX.

Everything in WPF can be made semi-transparent, everything can be overlaid over everything, including video, without any special effort. I tested it; it''s very easy.
