Convert youtube to mp3 using website

Question

I am trying to make a program that can download youtube videos as mp3 files. I used this youtube-mp3.org website to achieve this. So, I downloaded the contents of www.youtube-mp3.org/?c#v=sTbd2e2EyTk , where sTbd2e2EyTk is the identifier of the video, now I need to get a link to the mp3 file (in this case http://www.youtube-mp3.org / get? video_id ..... ), but there is no link in the downloaded content. I noticed that chrome developer tools (ctrl + shift + j, tab Elements) show that the link and view source option (ctrl + u) in chrome gives me the same result that I get when loading a page using java. How can I get this link? I tried to get the data using JSoap, but the data that I need is not loaded onto the page right away, so I can’t get it.

The following code is for loading the contents of a web page ...

URL tU = new URL("http://www.youtube-mp3.org/?c#v=sTbd2e2EyTk"); HttpURLConnection conn = (HttpURLConnection) tU.openConnection(); InputStream ins = conn.getInputStream(); BufferedReader rd = new BufferedReader(new InputStreamReader(ins)); String line; StringBuffer content = new StringBuffer(); while ((line = rd.readLine()) != null) { content.append(line); } System.out.println(content.toString()); 

I used this method to get the file, but I need a link.

  private static void downloadStreamData(String url, String fileName) throws Exception { URL tU = new URL(url); HttpURLConnection conn = (HttpURLConnection) tU.openConnection(); String type = conn.getContentType(); InputStream ins = conn.getInputStream(); FileOutputStream fout = new FileOutputStream(new File(fileName)); byte[] outputByte = new byte[4096]; int bytesRead; int length = conn.getContentLength(); int read = 0; while ((bytesRead = ins.read(outputByte, 0, 4096)) != -1) { read += bytesRead; System.out.println(read + " out of " + length); fout.write(outputByte, 0, bytesRead); } fout.flush(); fout.close(); }

I did this with youtube-mp3.org. You can see my code here: YoutubeMp3

All you have to do is the following:

  DownloadManager d = new DownloadManager(); d.download(YoutubeMp3.builder("http://www.youtube.com/watch?v=ebcrEqm5FFg"), "C:\\Users\\loikkk\\Music\\testDownload"); d.setDownloadListener(new DownloadListener() { @Override public void onDownloadStart(long totalFileSize) { // TODO Auto-generated method stub } @Override public void onDownloadProcess(long currentFileSize, long totalFileSize) { // TODO Auto-generated method stub } @Override public void onDownloadFinished() { // TODO Auto-generated method stub } @Override public void onDownloadError(int arg0) { // TODO Auto-generated method stub } }); 

Hope this helps,

@hanry and Josh M:

I deleted my Github account. However, if you use Google Chrome, you can use the developer console in a network perspective. Thus, you can change the configured download link as I did.

• Submit my Youtube URL to Youtube-mp-3.org
• View response from webservice
• Create a donwload link following the pattern they use.

Example:

Youtube url: http://www.youtube.com/watch?v=KMU0tzLwhbE ;

Web service request in content body: KMU0tzLwhbE

Reply from webservice: info = {"title": "Developers", "image": " http://i.ytimg.com/vi/KMU0tzLwhbE/default.jpg ", "length": "3", "status" : "serve", "progress_speed": "," progress ":", "ads": "," pf ":" http://ping.aclst.com/ping.php/10754233/KMU0tzLwhbE?h=401301 " , "h": "e8e446dbd937a0d8f636fdc8d8bb9874"};

Download link: http://www.youtube-mp3.org/get?ab=128&video_id=KMU0tzLwhbE&h=e8e446dbd937a0d8f636fdc8d8bb9874&r=1388680822878.1534658195
