Retrieving Shoutcast MetaData

[indiephp]

Hi, php newbie here..

 

Can you explain how can i use this stuff in php?

http://www.smackfu.com/stuff/programming/shoutcast.html

 

I found a phyton script:

http://jasonlebrun.info/2006/12/31/icy-metadata-shoutcast-song-titles/

 

and Java code (i guess):

http://www.codeproject.com/KB/audio-video/SHOUTcastRipper.aspx

 

But i didn't found any php solution for this problem anywhere

[indiephp]

i found this code and it works..

 

<?php
header("Content-type: audio/mpeg");
$fp = fsockopen("74.208.71.58", 8000, $errno, $errstr, 30);
if ($fp == false) {
echo "$errstr ($errno)";
} else {

fputs($fp, "GET / HTTP/1.1\r\n");
fputs($fp, "User-Agnet: WinampMPEG/2.9\r\n");
fputs($fp, "Accept: */*\r\n");
fputs($fp, "Icy-MetaData:1\r\n");
fputs($fp, "Connection: Close\r\n\r\n");

while (!feof($fp)) {
$buf = fread($fp, 1024 / 16);
echo $buf;
}
fclose($fp);
}
?>

 

Result is very strange for me. But at the same time it contains data which i need. (red line)

Actualy, the result is too long more than this. I think this is streaming audio data. 

 

Now, don't know how can i pick StreamTitle. I read again "Shoutcast Metadata Protocol document. He talks about metadata lenght.

 

Step 3: Get the metadata

This is the important part.

 

Read the data stream as you normally would, keeping a byte count as you go. When the number of bytes equals the metadata interval, you will get a metadata block. The first part of the block is a length specifier, which is the next byte in the stream. This byte will equal the metadata length / 16. Multiply by 16 to get the actual metadata length. (Max byte size = 255 so metadata max length = 4080.) Now read that many bytes and you will have a string containing the metadata. Restart your byte count, and repeat. Success!

 

Note that the metadata length is set to 0 most of the time, meaning there is no metadata. The metadata is normally sent at two particular places: immediately after connecting and when the song changes. It seems as if some servers aren't real diligent about the former, so it might take a while to get your first block.

 

Also, be sure you don't count the bytes in the metadata length field or the metadata when you're figuring out whether you've hit the interval. Only the MP3 data counts. So you can't be lazy and just keep a total byte count and mod it.

 

How to figure out? I am realy stuck.

I didnt paste all of the result because of special characters.

Therefore i attach screenshot.
