从视频提取音频作为MP3文件c＃ [英] extract audio as a MP3 file from video c#

问题描述

我想使用c＃从MP3视频文件中提取音频。音频的比特率应该能够指定。有人可以帮我吗？我已经看过是否，但是我不知道是否可以与否有关，而不提示CMD。

I want to extract audio from a video file as a MP3 using c#. The bit-rate of the audio should be able to specify. Could someone please help me on this? I have already looked at "whether" but I'm not sure whether it is possible to do with "whether" without prompting CMD.

请不要建议我下面的文章。对于大于700mb

推荐答案

您可以调用ffmpeg二进制文件而不创建单独的控制台窗口。我假设C＃/ .NET有模板，但如果没有，那么WinAPI的方法是在CreateProcess（）调用中指定运行的ffmpeg命令和stdin / stdout的虚拟句柄。这里描述的内容如下： http ：//msdn.microsoft.com/en-us/library/windows/desktop/ms682499（v = vs85）.aspx

You could call an ffmpeg binary without creating a separate console window. I'd assume C#/.NET has templates for that, but if not then the WinAPI way to do it is to specify the ffmpeg command to run and dummy handles for stdin/stdout in your CreateProcess() call. Something like that is described here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms682499(v=vs.85).aspx
