如何在PictureBox中显示视频文件缩略图？ [英] How to display Video File Thumbnails in PictureBox?

问题描述

我想在图片框中显示视频缩略图。我一直在寻找答案，但我发现的大部分内容（.GetThumbnailImage，System.Drawing.Image等）似乎只适用于图像，而不适用于视频。我想要做的就是显示与Windows文件浏览器相同的缩略图。我安装了ffmpeg，但是我发现的关于如何通过vb.net使用的文章对于像我这样的新手来说有点混乱。请帮助。

Hi, I would like to display a video thumbnail in a picturebox. I've been searching for answers, but most of what I've found (.GetThumbnailImage, System.Drawing.Image, etc.) seem to only work for images, not video. All I want to do is display the same thumbnail as windows file explorer. I have ffmpeg installed, but the articles that I've found on how to it use through vb.net are a bit confusing for a novice like me. Please help.

推荐答案

中心线索是你将自己描述为新手。文章告诉你如何做到这一点。新手应该学习他们选择的语言，而不是试着写一个最前沿的应用程序。



话虽如此， this [ ^ ]文章描述了你需要什么，我想。我会缓存缩略图，而不是在需求点生成缩略图。

The central clue is that you describe yourself as a novice. The articles are telling you how to do it. A novice should learn their language of choice, not try to write a cutting edge app.

Having said that, this[^] article describes what you need, I think. I would cache the thumbnails, not generate them at the point of demand.
