Hello!

Is it possible to create a icecast client built only in PHP with sockets?
I have an icecast server and I want to programatically add a new mount point for a very user who wants to create a favourite playlist.
I wonder if there's a documentation on how to talk to the icecast server through its listening port.

Thank you.

There are no language restrictions imposed, just use the libshout api to talk to icecast, if you don't want to use the slightly modified HTTP mechansim.

i want to develop this php client on windows so i need the win32 libshout extension for php. unfortunately i didn't find a version for windows so i figure that what libshout does can be done using the icy protocol.
it surprises me that there is no description of this protocol whatsoever.

icy was never documented but there are decent references out there. The basic mechanism for talking to icecast is http but using SOURCE as the method.

do you mean http request method = SOURCE?

hi!

i see from your posts that you are involved with icecast or closer to it. is it possible for you to send me or post here more information about the icy protocol? i believe it's not some war secret or something.

thank you.

hi again,

i've read those docs before but this the code i manage to write as far as i figure it out:

Code:
<?php
   $headers = array(
      "Authorization: Basic c291cmNlOmNoYW5nZW1l",
      "User-Agent: libshout/2.2.2",
      "Content-Type: audio/mpeg",
      "ice-name: My Stream",
      "ice-public: 0",
      "ice-url: http://www.mydomain.com",
      "ice-genre: rock",
      "ice-audio-info: bitrate=128;channels=2;samplerate=44100",
      "ice-description: This is a stream description"
   );

   $ch = curl_init();
   curl_setopt($ch, CURLOPT_URL, "http://127.0.0.1:8000");
   curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($ch, CURLOPT_TIMEOUT, 60);
   curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "SOURCE /live");
   curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);

   $data = curl_exec($ch);
   curl_close($ch);
?>


So i understand this the part that should mount a new folder /live to the icecast server. After i send those headers i really don't know what i should do: just fopen the mp3 file and output it as it is or... that just blows my mind out.

I haven't tried that combination but I suspect you want the URL to refer to /live and CUSTOMREQUEST to be "SOURCE". Also make sure you are using CURLOPT_HTTPHEADER correctly.

When properly executed you should find that /live is a mountpoint on the icecast server. There are no files or directories created. After the headers (for which authorization and content-type are important) you have the actual content or mp3 data in your case.

hello karl,

thank you for your support until now. i finally manage to get /live mountpoint to work. here is the code:

Code:

$headers = array(
"Authorization: Basic c291cmNlOmNoYW5nZW1l",
"User-Agent: libshout/2.2.2",
"Content-Type: audio/mpeg",
"ice-name: my name",
"ice-public: 1",
"ice-url: http://www.mydomain.com",
"ice-genre: rock",
"ice-audio-info: bitrate=128;channels=2;samplerate=44100",
"ice-description: This is a stream description"
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://127.0.0.1:8000/live");
curl_setopt($ch, CURLOPT_FRESH_CONNECT, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($ch, CURLOPT_FAILONERROR, 1);
curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "SOURCE");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_exec($ch);
curl_close($ch);


i don't know by now how to actually send data through this mountpoint. i tried:

Code:

curl_setopt($ch, CURLOPT_UPLOAD, 1);
curl_setopt($ch, CURLOPT_INFILESIZE, filesize('some.mp3');
curl_setopt($ch, CURLOPT_INFILE, fopen('some.mp3, 'rb'));


but this code plays in winamp only the last notes of the song, probably because it uploads itself too fast to the server. i noticed that if i leave the CURLOPT_UPLOAD = 1 and remove CURLOPT_INFILESIZE and CURLOPT_INFILE, the script keeps sending to the icecast server and this seems to receive something, i don't know what, as you may see in the log file below.

Code:

[2008-03-30  17:23:41] DBUG stats/stats.c new node total_bytes_read (0)
[2008-03-30  17:23:41] DBUG stats/stats.c new node total_bytes_sent (0)

[2008-03-30  17:24:10] DBUG stats/stats.c update node total_bytes_read (2827992)


i don't really know how to inject something into this empty stream. i even tried to output the mp3 with:

Code:

curl_exec($ch);
echo file_get_contents('some.mp3', FILE_BINARY);
curl_close($ch);


but i get no sound.

besides, i'd prefer to mount /live to a playlist.m3u or playlist.pls rather than a mp3 because that will play continously and that is what i want.
