从DVD上的avi文件中提取帧 [英] Extract a frame from an avi file on a DVD

问题描述

作为新手，我不具备从DVD上的avi文件中提取/捕获帧并将其另存为jpg文件在硬盘驱动器上的知识(不需要播放avi).

最近三天，我一直在网上寻找各种信息(DirectShow，ffmpeg，DrawToBitmap，MemoryStream ...)，但似乎没有显示我所需要的信息.

是否有一段简单的代码可以从avi文件中提取帧?

任何建议或信息将不胜感激.
谢谢.

As newbie I don''t have the knowledge to extract/capture a frame from an avi file on a DVD and save it as a jpg file on the Hard Drive (the avi doesn''t need to be played).

I have been looking on the net for the last 3 days, following-up various information (DirectShow, ffmpeg, DrawToBitmap, MemoryStream... ), but nothing seems to show what I need.

Is there a simple piece of code that will extract a frame from an avi file?

Any advice or information would be greatly appreciated.
Thanks.

推荐答案

您可能必须分两步来完成.首先，您必须将DVD翻录为AVI或其他某种视频格式.然后，您必须提取帧.

如果要这样做，我将从 vStrip [从视频文件中提取帧 [

you''ll probably have to do it in a couple of steps. First, you''ll have to rip the dvd to an avi or some other video format. Then, you''ll have to extract the frames.

If I were going to do it, I would start with vStrip[^]. It''s a command-line DVD ripping program, so you can interact with it programmatically. Then, I would look at this article: Extract Frames from Video Files[^]
