I'm using your script "YoutubeToMp3Converter.class.php" Everything was working fine yesterday from the same server but today I woke and tested the script and now getting this error:

Error downloading video, Please check your URL.!

Can you think of anything? did youtube changed their video URL code again?

My site convert youtube to mp3

Thanks for your help.

@expertmac,

What did you do to fix it? I'm having the same issue as you.

I'm getting the same error...I'll look into it and post a fix when I find one...

[chump2877]

It does appear that YouTube has changed the format of FLV URLs in the source code...

Unfortunately, I don't have any more time right now to investigate this...I'll dabble with developing a fix in my spare time...

In the meantime, anyone is welcome to provide the regex or series of regular expressions required to parse and grab the FLV video URL from YouTube's source code...

To be continued...

As I was typing my last post, I realized what the problem was...

Here is the fix (pending further testing?):

The SetFlvUrl() method has been revised as follows:

        private function SetFlvUrl($file_contents)
        {
            $vidUrl = '';
            if (eregi('url_encoded_fmt_stream_map',$file_contents))
            {
                $vidUrl = end(explode('url_encoded_fmt_stream_map=',$file_contents));
                $vidUrl = urldecode(urldecode(current(explode('&',$vidUrl))));
                $vidUrl = current(explode(';',$vidUrl));
                $vidUrl = urldecode(end(explode('url=',$vidUrl)));
            }
            $this->_flvUrl = $vidUrl;
        }

Hello,
Don't work any more

Hello,
Don't work any more

What is the YouTube video page URL that you are using? I may have to tinker with the regular expressions some more so that they work on all YouTube URLs?

FWIW, I haven't had any problems yet...

Here is an example :
http://www.youtube.com/watch?v=2ZCUt...eature=r_and_b

i use firefox.

Hey Chump I'm registering JUST to say thank you! You saved me man! Thank you so much.

But one question, could you show us how to do this ourselves just incase youtube updates again?

[chump2877]

Here is an example :
http://www.youtube.com/watch?v=2ZCUt...eature=r_and_b

i use firefox.

I just tried "http://www.youtube.com/watch?v=2ZCUtnuAXg8" and it works fine for me...I'm not sure if anything other than "v" in the query string would cause the app to fail, but like the app front end says:

Enter a valid YouTube.com video URL:
(i.e., "http://www.youtube.com/watch?v=HMpmI2F2cMs")

If other types of YouTube URLs dont work for you, then you'll need to write your own code to handle those URLs, or write some code to validate URLs so that they conform to the example URL format. (I didn't really program any validation because I'm just using this app recreationally, for my own personal use.)

Hope that helps....Good luck!

Unfortunately, I can't really give you a magic formula for how to tweak the regex when YouTube updates their site...It's mostly just "educated" guessing and a vague familiarity with how YouTube stores and encodes video data in their source code.

What I can say is that, this time, video data is found in this part of the source code (of any given video page):

The code in red is the URL-encoded FLV file location (I think I highlighted the right code -- it's hard to tell when it's encoded like that -- but that is the general vicinity in the source code)...It's just a matter of picking out the correct URL from that garbled mess and then URL-decoding it...

Also, as an aside, the series of regular expressions that I used in SetFlvUrl() could probably be made more efficient (from a coding perspective), but:

1) I wrote the code quickly, and
2) The code does what I need it to do, so I guess I don't care

As always, if something (namely, the regex) doesn't work, let me know and I'll try to fix it....But as long as it works, no matter how ugly it might look, I'm good with it
