缩略图视频C# [英] Thumbnail video C#

问题描述

是否可以用C#(如第一帧)创建视频的缩略图?

Is it possible to create a thumbnail image of a video in C# (like the first frame)?

小更新:由于我正在使用Flex来显示视频，因此我需要C#中的FLV视频的缩略图.是的，链接到某些库将很有用.

Little update: I'll need a thumbnail image of an FLV video in C# since I'm using Flex to show video's. And yes, links to some libraries would be useful.

推荐答案

我可以想到两个选项:

1. 使用外部工具(例如 ffmpeg )来生成缩略图.这可能是解决此问题最常用的解决方案.
2. 解析FLV文件，仅将其发送到第一个 I帧的结尾.(您可以在代码中找到解析逻辑，该逻辑使您可以按时间标记查找FLV的中间位置.

1. Use an external tool, like ffmpeg, to generate thumbnails. This is probably the most commonly implemented solution to this problem.
2. Parse the FLV file and only send the file only to the end of the first I Frame. (You can find the parsing logic in code that allows you to seek into the middle of an FLV by time mark.
