Justin.tv API

[tdhz77]

I want to try and script a small program that simply $GET's my broadcast video only if my stream is up.

 

http://techblog.justin.tv/2007/11/jtv-search-api.html

 

For more information.

 

I'm so lost. Any documentation, ideas or pointers would be great. I would like to do this thing on my own, but any examples on how to go about an HTTP request would be nice.

would file_get_contents() work i wonder

 

example try it.

<?php

$stream_url='what_ever';

if(file_get_contents("$stream_url")){

echo working;

}else{

echo "Not working";

}

?>

Sorry but there no way to see if the tv program is live, The only way is to cheek to see if the url exists.

 

this is what the current database let you see what going on.

 

But the database does not tell you if the tv program is currently live.

 

The only way you can rely cheek this, is to alter the database and use a cron, and update

a database field each time a user press the watch button.

 

But that wont even help rely, Only tell you at that time, The tv stream was working.

 

Your have to rely on the url exists i think sorry.

 

But that does not tell you the stream is live only the url is there.

 

Even if you ping the streaming url your still only cheeking the url exists.

How theo, i got this one but how you going to do this intresting.

 

would socket help?

<?php
// set some variables
$host = "192.168.1.99";
$port = 1234;
// don't timeout!
set_time_limit(0);
// create socket
$socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create
socket\n");
// bind socket to port
$result = socket_bind($socket, $host, $port) or die("Could not bind to
socket\n");
// start listening for connections
$result = socket_listen($socket, 3) or die("Could not set up socket
listener\n");
// accept incoming connections
// spawn another socket to handle communication
$spawn = socket_accept($socket) or die("Could not accept incoming
connection\n");
// read client input
$input = socket_read($spawn, 1024) or die("Could not read input\n");
// clean up input string
$input = trim($input);
// reverse client input and send back
$output = strrev($input) . "\n";
socket_write($spawn, $output, strlen ($output)) or die("Could not write
output\n");
// close sockets
socket_close($spawn);
socket_close($socket);
?>

My idea is to use some tools to extract a frame from the stream it's self. Then compare that frame with the default non-streaming image.

 

If the frame is different the stream is most likely active, if it's not the stream is most likely not active.
