I used the following code to download HTML files and subtitle files over the Internet. But when I give the url of a Youtube video, the download stops very quickly and though some file IS downloaded, it doesn't open. Why ?

class read
{
	public static void main(String aa[])throws IOException
	{
		byte a;
		int  b,c,d;
		URL url=new URL("http://www.youtube.com/v/sHQXU9Kzgr8&color1=0xb1b1b1&color2=0xd0d0d0&hl=en_US&feature=player_detailpage&fs=1");
		URLConnection conn=url.openConnection();
		InputStream stream=conn.getInputStream();
		FileOutputStream out=new FileOutputStream("/home/daud/Desktop/video");
		while ((b=stream.read())!=-1)
			out.write(b);
	}
}

Maybe the server doesn't want you to download the file.
What do you receive when you have the problem?
Rename the file received to .txt and open it in an editor.

Have you tried catching and displaying any Exceptions that may be thrown?
And if you're reading/writing individual bytes, you should use buffered streams or it may just grind to a near halt on a large file

I tried to catch exceptions but there were none. When I tried to change the file to txt and open it by gedit, it said that it couldn't recognize the coding. Why did the download stop so quickly ?

This is what I found when I opened it through vi :

That doesn't look like hex characters.
Can you open it in a hex editor and display the contents in hex?
Also open a video file of the same type in the hex editor and compare the first few bytes of it to the mystery file's contents to see if you were starting to get a video file and then were cut off.
