Project Description
Video Downloader makes it easier for developers to generate download links for videos from You-Tube as well as getting information on the video itself. You'll no longer have to search through HTML source code on the You-Tube Website.

Abandoned Project - This project has since been abandoned due to time constraints and changes at YouTube.
With each change of YouTube's website this DLL has to be updated to search for the new download link. I am no longer able to constantly provide updates to this project to continue to get download links to work.

If you are interested in continuing to use this software visit http://www.codeproject.com/KB/cs/YouTube_Downloader.aspx where a guide has been created. Several members have also contributed bug-fixes and changes which might allow the downloading of videos once more.

This Software is to only be used to download videos that you own the full rights too, and that do not Infringe on copyright laws.
Use of this software is against You-Tube's Terms and Conditions. - Although if you own the video and need to make a backup it may be acceptable.

Example usage showing what information the DLL can be used to retrieve:

How to Use the DLL in your Project:

Generating Video Download Links.

1. Add a Reference to the DLL in your project.

Public Class Form1
    Private downloadmaker As New Video_Downloader_DLL.VideoDownloader
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim output As String = ""
        downloadmaker.MakeDownloadURL("http://www.youtube.com/watch?v=hwQdGY6JuDY", output)
        MsgBox(output)
    End Sub
End Class

*Where output is the generated download URL for that particular You-Tube Video.

Getting the You-Tube Videos Video Title

1. Add a Reference to the DLL in your project.

Public Class Form1
    Private downloadmaker As New Video_Downloader_DLL.VideoDownloader
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim videotitle As String = ""
        downloadmaker.GetVideoTitle("http://www.youtube.com/watch?v=hwQdGY6JuDY", videotitle)
    End Sub
End Class

*Where videotitle is the Video Title for that particular You-Tube Video.

Generating Video Thumbnail URLs.

1. Add a Reference to the DLL in your project.

Public Class Form1
    Private downloadmaker As New Video_Downloader_DLL.VideoDownloader
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Dim thumbnailurl As String = ""
        downloadmaker.GetPreviewThumbnail("http://www.youtube.com/watch?v=hwQdGY6JuDY", thumbnailurl)
    End Sub
End Class

*Where thumbnailurl is the generated URL for that particular You-Tube Video Thumbnail for that video.

This link is 2 years old but may explain some of the antics at youTube: http://hothardware.com/News/YouTube-Begins-to-Kill-Off-Video-Download-Tools/

Until things are fixed: This works, is free, and has been updated! Tested today! http://www.wondershare.com/pro/free-youtube-downloader.html

I downloaded this about 3 days ago.

I also modified the .dll so it would work again, but now after 2 days its stopped working again :(

Does anybody have a fix ? :)

I agree, I made the recent changes and it worked, but today it's broken again.

Yeah, google made changes again. Its worked for awhile after changing that line of code and then a few days ago google changed the url sheme again.

Hopefully the author can find the time to update the library. I'm not sure about the changes google made to be able to fix any of the code myself.

Thanks

Thankyou VERY much. That actually fixed it. I guess Youtube changed some minor setting or something...

Hard to believe it just needed a single line of code. Thanks again! :)

Here is the fix:

1) Place the following line of code under this line:

signature = signature.Replace("%2C", ",")

signature = signature.Replace("\", "") <---- new line of code

It should work, you will have to recompile the .dll file though.

I know this is a old library and no one may read this message, but just in case I am wondering if you get an error message: "Index was outside the bounds of the array." when trying to call the "MakeDownloadURL" sub.

If you have a fix or know of a library that still works with youtube, please let everyone know. :)

I'm not sure if your still interested in updating your video downloader library, but it no longer works correctly. Whenever you try to call the "MakeDownloadURL" sub, it will throw an error message: "Index was outside the bounds of the array."

Would be great if you could find the time to update it. Thanks
