Hello folks,

I am looking for a script that can read song information from a stream playing on a parcel, parse out the title and artist information, and return it as a string (for example, for LLSetText).

I have a full-perm radio that does this, but I am not an confident or experienced enough programmer to decipher which parts of the script I need to strip out and which parts control other aspects of the radio. Well, I probably could with a bunch of trial and error, but if someone already has a suitable script that would be much easier on me.

Background: I have, in Madhu's inventory, a very simple display board that reads title and artist from the stream, writes it to hovertext, and shouts into chat when the song changes. It's not transferable, and I would like one for Carter, who has taken over all my DJ gigs. The shop I bought it from now has a newer version, but it is a huge monstrosity that uses XY-text and looks like an ugly club board. I asked the shopkeeper if he could sell me another copy of the old version, and he said he no longer had it and the creator of it has left SL.

So I was hoping I could build one for myself, and I'd hoped I could decipher the full-perm radio script, but I'm a bit daunted by the task.

I'd appreciate any help anyone can offer.

I'd also be happy just to buy a new display if anyone knows of one that's not too big and not too ugly (or that is modifiable).

Madhu:

I've never played around with scripting the media stream, so this response is offered solely on a "just in case a better one doesn't come along".

I'd be happy to at least have a quick look if you could post said script here.

Very basic script for shoutcast servers.

Code:

// 7.html gives the following in the body
// 0 -> current listeners
// 1 -> status
// 2 -> listener peak
// 3 -> max listeners
// 4 -> reported listeners
// 5 -> bitrate
// 6 -> song


string stream = "YOUR STREAM URL"; 
key kSentRequest;

default
{
    state_entry()
    {   
        string URL = stream + "/7.html HTTP/1.0\nUser-Agent: XML Getter (Mozilla Compatible)\n\n";
        kSentRequest = llHTTPRequest(URL, [], "");
    }
    
    http_response (key kRecRequest, integer intStatus, list lstMeta, string strBody)
    {
        if (kRecRequest == kSentRequest)
        {   
            // Strip the html out of the received information and just show what is inbetween the body tags
            list html = llParseString2List(strBody,["<body>", "</body>"],[]);
            string info = (llList2String(html,1));
            
            list status = llCSV2List(info);
            
            llSay(0," Current Listeners: " + llList2String(status,0));
            llSay(0,"Status: " + llList2String(status,1));
            llSay(0,"listener peak: " + llList2String(status,2));
            llSay(0,"max listeners: " + llList2String(status,3));
            llSay(0,"reported listeners: " + llList2String(status,4));
            llSay(0,"bitrate: " + llList2String(status,5));
            llSay(0,"Song: " + llList2String(status,6));
            kSentRequest = NULL_KEY;
        }
    }
}

Carter-Madhu · 07-14-2009, 09:22 PM

Thank you both so much!

Johnnie: dumb question.

Will that script automatically update when the song changes, or do I need to put the http_response portion inside of some timer event to get it to check periodically?

Free Xue · 07-14-2009, 09:24 PM

Here is a *simple* script modified from the one I wrote for my own DJ titler. It can take the music url from the music_url string or from the description field of the object. I don't think there is a way to get the music url from the land profile (at least I've never found a way).

Code:

// leave music_url blank if set in object's description
string music_url = ""; 

key HTTPRequest;
string feed;
string URL;
string currSongTitle;
string lastSongTitle;
list feedList;

default
{
    state_entry()
    {
        llSetText(" ",<1,1,1>,1);
        llSetTimerEvent(5.0);
    
        if(music_url) 
        {
            URL = music_url;
        } else {
            URL = llGetObjectDesc();
        }
    }

    timer()
    {
        HTTPRequest=llHTTPRequest(URL + "/7.html HTTP/1.0\nUser-Agent: LSL Script (Mozilla Compatible)\n\n",[],"");
    }

    http_response(key k,integer status, list meta, string body)
    {
        if(k != HTTPRequest) return;

        feed = llGetSubString(body,llSubStringIndex(body, "<body>") + llStringLength("<body>"), llSubStringIndex(body,"</body>") - 1);
        feedList = llParseString2List(feed,[","],[]);
        currSongTitle = llList2String(feedList,6);
        integer length = llGetListLength(feedList);
        
        if(llList2String(feedList,7))
        {
            integer a = 7;
            for(; a<length; ++a)
            {
                currSongTitle += ", " + llList2String(feedList,a);
            }
        }
         
        if (currSongTitle != lastSongTitle)
        {
            llSetText(currSongTitle,<1,1,1>,0.75);
            lastSongTitle = currSongTitle;
        }
    }
}

EDIT: This is also a Shoutcast-specific script. Timer takes care of the song changes. Also note it's a little smarter about song titles than the one Johnnie pasted in (correcting for when they have commas, which causes problems if you just grab the #6 index in the list.

Carter-Madhu · 07-14-2009, 09:26 PM

Thank you thank you !

Johnnie Carling · 07-14-2009, 09:26 PM

Yea this is a basic grab the info and stop script

I'd put the lines in state_entry in it's own function, then run that function in a timer.

and add whatever channel changing, and display options you want

Try removing the closing slash on your stream URL for the music_url string, or alternatively change it in this line:

Quote:

HTTPRequest=llHTTPRequest(URL + "/7.html HTTP/1.0\nUser-Agent: LSL Script (Mozilla Compatible)\n\n",[],"");

to:

Quote:

HTTPRequest=llHTTPRequest(URL + "7.html HTTP/1.0\nUser-Agent: LSL Script (Mozilla Compatible)\n\n",[],"");

But I personally would just edit it in the music_url string.

demoney420 · 08-02-2009, 04:54 PM

sorry im dumb lol but i got it to work now. ...

but if i want to add more info how can i get the strings like now it shows the current song but i would like to add things like
stream title like Stations Name
Previous Songs
Stream Url
Stream Genre

Things like dat

You'll need something more robust than the scripts above, as they only read and parse the "7.html" page a Shoutcast server outputs, which gives info only on the current or last song.

It *may* be possible to parse the Shoutcast status page, but llHTTPRequest() has a low limit of 2048 bytes for a document. Anything beyond that is truncated, and the status page is far larger than that.

The best tools I've seen for this first capture the data using a separate, web-based tool (such as a PHP script) that transforms the status page into something they can better target (say an XML or CSV document) for use with llHTTPRequest().

Can't help with Java as I don't know it. A PHP (with accompanying LSL) script for this would be something I could do, though. But for this to work for you, you'll need a web host somewhere you can run and reach the PHP script.

I can write it and test it, but I cannot host it.

Hehe, I think the last thing you want is others leeching off your service. Though it would be easy to pass the Shoutcast URL as a GET and make the script a generic tool for anyone who wants to use it..... Nah.

So... here's two PHP scripts I whipped up. The first deals with the general status page on a Shoutcast server, and the second talks to the "played.html" page. You could combine them, but 2 points to consider:

1. To make the data as normalized as I could for LSL scripting, they output to the "standard" SL notecard config format, where each bit of data is on its own line:

Code:

Server Status: Server is currently up and public.
Stream Status: Stream is up at 96 kbps with 11 of 25 listeners (8 unique)
Listener Peak: 14
Average Listen Time: 0m 42s
Stream Title: DJ SLU
Content Type: audio/mpeg
Stream Genre: Punk/Techno/Waltz
Stream URL: http://shout.sluniverse.com:12345
Stream AIM: N/A
Stream IRC: #shoutcast
Current Song: Green Day - Basket Case

Combining it with the output of played.html would require further evaluation to parse it all correctly, whereas two separate 'feeds' scripted independently avoids the problem.

2. Again, the issue of requested documents getting truncated at 2K I think makes a good case to handle them separately.

...

I didn't tackle the parser on the LSL side. Don't really have the time; but there's lots of LSL scripts floating around that handle notecard (config) reading that can be adapted. Anyway, the fun in all this is when it gets to be collaborative, right?

So... PHP scripts, finally!

shout2notecard.php:

Code:

<?php
// user-configurable var: Shoutcast server URL
$shoutcast_url = 'http://shout.sluniverse.com:12345';

error_reporting(0);
ini_set('user_agent', 'Mozilla');
header('Content-type: text/plain; charset=utf-8');
$html = file_get_contents($shoutcast_url);

$dom = new domDocument;
$dom->loadHTML($html);
$tables = $dom->getElementsByTagName('table');
$rows = $tables->item(3)->getElementsByTagName('tr');

foreach($rows as $row)
{
    $cols = $row->getElementsByTagName('td');
    echo $cols->item(0)->nodeValue;
    echo $cols->item(1)->nodeValue."\n";
}
?>

shout-played2notecard.php:

Code:

<?php
// user-configurable var: Shoutcast server URL
$shoutcast_url = 'http://shout.sluniverse.com:12345';

error_reporting(0);
ini_set('user_agent', 'Mozilla');
header('Content-type: text/plain; charset=utf-8');
$html = file_get_contents(rtrim($shoutcast_url, '/').'/played.html');

$dom = new domDocument;
$dom->loadHTML($html);
$tables = $dom->getElementsByTagName('table');
$rows = $tables->item(2)->getElementsByTagName('tr');

foreach($rows as $row)
{
    $cols = $row->getElementsByTagName('td');

    if(!strstr($cols->item(0)->nodeValue,'@'))
    {
        echo $cols->item(0)->nodeValue . ': ';
        echo $cols->item(1)->nodeValue;

        if($cols->item(2)->nodeValue)
            echo '*'.$cols->item(2)->nodeValue.'*';

        echo "\n";
    }
}
?>

Notes:

I wrote and tested both on a PHP5 setup (5.2.9).

I strip out the column headers in played.html (Played @ and Song Title), but these can easily be left in if wanted.

Error reporting is turned off because... well, the DOMDocument class loadHTML() function has issues with badly formed HTML, something Shoutcast server pages are littered with.

Ok, any questions about the code, have at the asking thing!

Hey - I just wanted to say, I finally got around to trying the script Free posted and it worked like a dream! And it's simple enough that I was able to hack it to add a few more features I wanted. Thanks so much to everyone who helped me with this!

Frau Yardley · 10-29-2009, 06:34 PM

Hello all.

I hope you dont mind me joining this discussion.
I am looking for something similar, something that announces the song playing and the artist, etc.
I tried the scripts here and they work.

But I would like them to do something more, my apalogies if this was actually mentioned earlier, but I would want the script to say the information in chat.

I have a little radio in my club that I would like to 'chat' this information when there is no DJ or anyone else.
So automatically when a new song starts it chats ;the next song is, and then the information it gets from shoutcast, etc.

I modded Free's script to do just this. It's not perfectly timed with the start of a new song - it can't be, because the stream is different for each listener - but it works very well and usually changes within 30 seconds of the change of songs.

I'll be happy to drop my version of the script on you in world when I get in a bit later. Is Fraulein Yardley your SL name?

I've been using the above (closer to the top) bit of code to pull the song info from the stream. I've got the script set in a little ball I made and added a few extra lines of code so when you click it, it will shout the song title.

What I'm currently using:

Code:

// leave music_url blank if set in object's description
string music_url = "";

key HTTPRequest;
string feed;
string URL;
string currSongTitle;
string lastSongTitle;
list feedList;

default
{
    state_entry()
    {
        llSetText(" ",<1,0,0>,1);
        llSetTimerEvent(5.0);
    
        if(music_url) 
        {
            URL = music_url;
        } else {
            URL = llGetObjectDesc();
        }
    }

        if (currSongTitle != lastSongTitle)
        {
            llSetText(currSongTitle + "\n\nClick anywhere to shout track information",<1,1,1>,0.75);
            lastSongTitle = currSongTitle;
        }
    }
    touch_start(integer num_detected)
    {
        llShout(0, "You're listening to '" + currSongTitle + "'");
    }
}

Everything works great. What I'm currently doing is I have the stream URL in the description which the script reads from.

What I would like is to add a / command or even a menu script or something that would allow me to change the stream URL without having the URL listed in the Description as some URLs I would like to keep hidden.

I am kind of new at scripting so any guidance would be greatly appreciated.

Thank you

Code:

integer Channel = 123;
float Time = 5.0;

key HTTPRequest;
string feed;
string URL;
string currSongTitle;
string lastSongTitle;
list feedList;

default
{
    state_entry()
    {
        llSetText(" ",<1,0,0>,1);
        llListen(Channel, "", llGetOwner(), "");
        llOwnerSay("Starting. Change stream on channel " + (string)Channel );
    
        if( URL != "" )
        {
            llSetTimerEvent(Time);
        }
        else
        {
            llOwnerSay("Stream has not yet been set!");
        }
    }

    timer()
    {
        HTTPRequest=llHTTPRequest(URL + "/7.html HTTP/1.0\nUser-Agent: LSL Script (Mozilla Compatible)\n\n",[],"");
    }

    http_response(key k,integer status, list meta, string body)
    {
        if(k != HTTPRequest) return;

        feed = llGetSubString(body,llSubStringIndex(body, "<body>") + llStringLength("<body>"), llSubStringIndex(body,"</body>") - 1);
        feedList = llParseString2List(feed,[","],[]);
        currSongTitle = llList2String(feedList,6);
        integer length = llGetListLength(feedList);
        
        if(llList2String(feedList,7))
        {
            integer a = 7;
            for(; a<length; ++a)
            {
                currSongTitle += ", " + llList2String(feedList,a);
            }
        }
         
        if (currSongTitle != lastSongTitle)
        {
            llSetText(currSongTitle + "\n\nClick anywhere to shout track information",<1,1,1>,0.75);
            lastSongTitle = currSongTitle;
        }
    }

    touch_start(integer num_detected)
    {
        llShout(0, "You're listening to '" + currSongTitle + "'");
    }
    
    listen (integer channel, string name, key id, string message)
    {
        if( llGetSubString(message,0,6) == "http://" )
        {
            URL = llStringTrim(message,STRING_TRIM);

            if( llGetSubString(URL,-1,-1) == "/" )
                URL = llDeleteSubString(URL,-1,-1);

            llSetTimerEvent(Time);
            llOwnerSay("Stream changed to : " + URL);
        }
        else
        {
            llOwnerSay("Address appears invalid. Stream was not changed.");
        }
    }
}

That will let you set a stream URL through channel 123 in local chat.

Does a tiny bit of validation on the URL you enter (just makes sure it starts with http://), as well as stripping off any trailing slash.

Thank you, that actually worked out pretty good.

I got to messing around a bit and improved my little ball prim and made into a box and drew a little radio picture for the front of it. I added a 2nd prim to it and added the following script into it:

Code:

string music_url1 = "http://mystream1.net:12345";
string music_url2 = "http://mystream2.net:54321";

integer CHANNEL = 99;
list MENU_MAIN = ["Main", "Backup"];

default
{
    state_entry()
    {
        llListen(CHANNEL, "", NULL_KEY, "");
    }
    
    touch_start(integer total_number) 
    {
        llDialog(llDetectedKey(0), "Select a stream:", MENU_MAIN, CHANNEL);
    }
    
    listen(integer channel, string name, key id, string message) 
    {
        if (llListFindList(MENU_MAIN, [message]) != -1) 
        {
            if (message == "Main")
            {
                llOwnerSay("Main Stream - " + music_url1);
                llSetParcelMusicURL(music_url1);
            }
    
            else if (message == "Backup")
            {
                llOwnerSay("Backup Stream - " + music_url2);
                llSetParcelMusicURL(music_url2);
            }
        }

        else
        {
            llOwnerSay("There was an error!");
        }
    }
}

What I would like to do is click this prim which brings up a menu so I can swap streams. How would I go about sending the stream info to the other script. I know there's a way but am having difficulty in locating guides on this.

Again, thank you for any help.

Hello folks, I am looking for a script that can read song information from a stream playing on a parcel, parse out the title and artist information, and return it as a string (for example, for LLSetText). I have a full-perm radio that does this, but I am not an confident or experienced enough programmer to decipher which parts of the script I need to strip out and which parts control other aspects of the radio. Well, I probably could with a bunch of trial and error, but if someone already has a suitable script that would be much easier on me. Background: I have, in Madhu's inventory, a very simple display board that reads title and artist from the stream, writes it to hovertext, and shouts into chat when the song changes. It's not transferable, and I would like one for Carter, who has taken over all my DJ gigs. The shop I bought it from now has a newer version, but it is a huge monstrosity that uses XY-text and looks like an ugly club board. I asked the shopkeeper if he could sell me another copy of the old version, and he said he no longer had it and the creator of it has left SL. So I was hoping I could build one for myself, and I'd hoped I could decipher the full-perm radio script, but I'm a bit daunted by the task. I'd appreciate any help anyone can offer. I'd also be happy just to buy a new display if anyone knows of one that's not too big and not too ugly (or that is modifiable). __________________ Pocket Gardens -- prefab landscaping \|\|\| Madhu's Cafe world music coffeehouse

Will that script automatically update when the song changes, or do I need to put the http_response portion inside of some timer event to get it to check periodically?

Johnnie Carling Senior Member DEUS EST HOMO Join Date: Nov 2007 Posts: 2,692 My Mood: SL Join Date: 2007-08-17 Client: Viewer Development	Yea this is a basic grab the info and stop script I'd put the lines in state_entry in it's own function, then run that function in a timer. and add whatever channel changing, and display options you want

And it's simple enough that I was able to hack it to add a few more features I wanted. Thanks so much to everyone who helped me with this!

I hope you dont mind me joining this discussion. I am looking for something similar, something that announces the song playing and the artist, etc. I tried the scripts here and they work. But I would like them to do something more, my apalogies if this was actually mentioned earlier, but I would want the script to say the information in chat. I have a little radio in my club that I would like to 'chat' this information when there is no DJ or anyone else. So automatically when a new song starts it chats ;the next song is, and then the information it gets from shoutcast, etc.
