Downloading Youtube clips

[vadi]

Hi everyone

I'm trying to create a program on which i can download youtube clips bye pasting their links into a textbox and pressing a button but don't know how to do it. I searched in google but i couldn't find the right solution. I hope someone can help me.

Thanks in advanced!!!!!

Have you seen if they have any info on that on http://www.youtube.com/dev?

What language are you using?

[vadi]

Hi

I'm using Visual basic (vb.net 2005 IDE).

[Hack]

How about something like (untested)

My.Computer.Network.DownLoadFile(Textbox1.Text, "c:\vadi", "username", password")

[DigiRev]

The hard part might be trying to get the URL to the actual media file/flash video embedded in the page.

I could be mistaken, but I think they use JavaScript or something else to encode the URL to the .swf video file.

[RobDog888]

Its a dynamically determined path on a different server for downloading the flv file

[Lord Orwell]

is there a way to determine the actual link? Perhaps calling the javascript?

[RobDog888]

Well there is a javascript variable that contains the path.

var swfUrl = '/player2.swf';
var swfArgs = {"e": "h", "sourceid": "y", "video_id": "6MFMEUtmF-A", "l": 44, "sk": "JKO_asxtlW_xe3eIs0UZ9AU", "t": "OEgsToPDskIZ6fUnnYIqLcvRuEZxQKSz", "hl": "en", "plid": "AARFlSgZ9IjBOJviAAAAoAAYAAA", "sdetail": "p%3A/browse"};

I have The Method to Access to Those Clip flv without any programme
so if interested i can post how to get it & then we can you cree the algo for it & running in vb.Net 2005 & post it in the CodeBank !

[RobDog888]

Sure sounds good.

[killer7k]

oK let's Take an Example !
1/This is the Link original from Youtube

http://www.youtube.com/watch?v=Ulf5CdFykX0

2/we will change This Url Like This way

http://www.youtube.com/watch/v/Ulf5CdFykX0

we removed the ? & = and replaced with /
when you type this 2 url you will Get The Url of the page like this
3/In The Browser Get The Url After &t= like

http://www.youtube.com/swf/l.swf?vid...n7pyvjYR30g849

Now This is The mean what we need , if we look well in the url what we need is this

&t=OEgsToPDskIpUGfLc8AzYa2_L5Zq_MSI

The one started from &t

4/Now enter The Full URL Like this & download Your file

http://youtube.com/get_video.php?vid...AzYa2_L5Zq_MSI

if we see very well
Ulf5CdFykX0 = The id of the url
&t=OEgsToPDskIpUGfLc8AzYa2_L5Zq_MSI = The link to download it

so Now we need to work on a algo that will do those operations

Thanks !

[RobDog888]

Oh yes I remember that method. Its from this post by Chris001
http://www.vbforums.com/showpost.php...78&postcount=2

But it seems there are some issues with it as noted in the thread.

My solution works fine if you want to download the video right away, but you can't post the final link on an other webpage, because the link expires.

[killer7k]

sorry I havent seen This Thread before , because this way i got it from my sister

[RobDog888]

Well as long as the issue gets solved

We cant be sure but it may appear that its for immediate download but if not then the links will be broken.

[vadi]

First of all thanks for your replies!!!!!!

Guys i tried this things but it only downloads only a small file like 100kb or so.
So it doesnt work. I would eppriciate if someone could give me a sample of that cos i don't think that i can do it otherwise.

Thanks in advanced!!!

[RobDog888]

I followed the directions ffrom the link I posted and it downloaded a 7.9 MB file.

This is my end result url I constructed but remember that it will only be available for a short time.

[Lord Orwell]

they worked for me too, IN A BROWSER. If you try to copy the link into a download accelerator, it fails. Incidently, if you get a 100kb file, rename it with a .htm extension and look again...

[vadi]

Guys thanks for your efforts but this is not what i was looking for. I expected code or a sample program. I will google a bit and see what i can find.

Thank

Thank

Because it's Not a Direct Link !

i put this together, it's best to run it in another thread ( Backgroundworker ) otherwise the app will sit there locked out until the download has done.
i tested it on a few vids.

        '/// ENTER THE URL THAT YOU WOULD WATCH THE VID ON IN BROWSER ...
        Dim request As HttpWebRequest = DirectCast(HttpWebRequest.Create("http://www.youtube.com/watch?v=FJaAe7sYoCA"), HttpWebRequest)
        Dim response As HttpWebResponse = DirectCast(request.GetResponse, HttpWebResponse)

        Dim source As String = New StreamReader(response.GetResponseStream, System.Text.Encoding.Default).ReadToEnd

        If source.IndexOf("video_id=") > -1 Then
            Dim url As String = System.Text.RegularExpressions.Regex.Split(source, "video_id=")(1)
            url = "http://www.youtube.com/get_video?video_id=" & System.Text.RegularExpressions.Regex.Split(url, "&title=")(0)

            Dim wc As New WebClient
            wc.DownloadFile(url, "C:\FJaAe7sYoCA.flv")
        End If

        response.Close()

might start you off.

[Chris001]

Here's a VB6 version. Internet Explorer must be installed, because it uses DoFileDownload to download the video.
