从视频文件中提取 wav 文件 [英] Extract wav file from video file

问题描述

我正在开发一个应用程序，我需要在其中从视频中提取音频.音频需要以 .wav 格式提取，但我对视频格式没有问题.任何格式都可以，只要我能在 wav 文件中提取音频.

I am developing an application in which I need to extract the audio from a video. The audio needs to be extracted in .wav format but I do not have a problem with the video format. Any format will do, as long as I can extract the audio in a wav file.

目前我正在使用 Windows 窗体中的 Windows Media Player COM 控件来播放视频，但任何其他嵌入式播放器也可以.

Currently I am using Windows Media Player COM control in a windows form to play the videos, but any other embedded player will do as well.

关于如何做到这一点的任何建议?谢谢

Any suggestions on how to do this? Thanks
