Extracting mp3 audio file from youtube video in C#

问题描述:

I am building a program(in C#) and I need to download the audio from a youtube video(using the URL). I found two libraries which allow me to do it:

YotubeExtractor and libvideo(Also known as VideoLibrary), but I don't know how to use them, I mean I tried using their documentation but non of them worked.

Do you know another way which I can download or maybe explain me how to do this?

Thank you and have a nice day!

网友答案:

Don't use other people's code unless it's large and popular or your only option, I recommend, so that you both learn more and know how it works, as well as know how to maintain it if it breaks.

Retrieve the page using standard .NET functionality, parse out the HTML to find the video URL, download it using the same standard functionality, and then convert it to MP3 as a separate logical unit of your software.

For converting to MP3 you may well want to use someone else's library or call an external program like FFMPEG since that's not as trivial as parsing a webpage.
