Converting videos from YouTube to mp3


Hello! In this post, I'll show you my small new project. With this software, you can download Youtube videos as mp3 files. It works with where program sends commands that convert video and sends download link of mp3 file to the program.

Using the Code

To convert a video, you must do the following three steps:

  1. Submit a link of the video you want to convert.
  2. Send command to and get the download link of mp3 file.
  3. Download mp3 file.

Now see that in code!

  1. TextBox1 is textbox for video URL. Button2 is convert button. This code checks video URL. Place this code on Button1_Click event. Button1 is submit or check button.
    If TextBox1.Text.StartsWith("") Then
    	Button2.Enabled = True
    	Button2.Enabled = False
    End If  
  2. This code sends video URL and convert command. Button3 is download button. Place this code on Button2_Click event.
    WebBrowser1.Document.GetElementById("youtube-url").SetAttribute("value", TextBox1.Text)
    Button3.Enabled = True  
  3. This code starts downloading the mp3 file. Place this code on Button3_Click event.
    Dim download_link As HtmlElement = WebBrowser1.Document.GetElementById("dl_link")
    Dim links As HtmlElementCollection = download_link.GetElementsByTagName("a")
    Dim link As String = links(0).GetAttribute("href")
  4. This code navigates web browser to the webpage where converting starts. Put it on Form1_Load event.

In this project, you need TextBox1, Button1, Button2, Button3, WebBrowser1.

The workflow of the[^] seems to have changed. Now without the additional number after the dot of the timestamp the link redirects back to the conversion. Thus your program is not working anymore - at least it seems like it.
