问题描述
我正在开发中，我需要提取从视频音频的应用程序。音频需要以.wav格式将被提取，但我不具有与视频格式的一个问题。任何格式都行，只要我能提取一个WAV文件中的音频。
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.
目前我使用的Windows Media Player COM控件在Windows窗体中玩视频，但其他嵌入式播放器会做的一样好。
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.
