Integrating VideoWhisper Applications with other scripts

admin — Sat, 04 Feb 2012 16:00:45 +0000

If you’re using a standard CMS like Drupal, WordPress, Joomla, Elgg, Moodle you can find some ready made integrations to start from, on VideoWhisper.com . Otherwise you should start from the plain php editions.

All integrations include full php in source form, that can be downloaded for free from the downloads section (after registering a free account).
Integration is not affected by the license. When domain is licensed flash application starts in full mode (without limitations and intrusive ads showing in flash interface).

Integration depends mainly on site developers and site logic. We recommend starting with the simple php editions when integrating with new scripts. If needed apps can be tweaked to call other types of scripts (asp, jsp). Most already include parameters to change external script call path and extension.

LOGIN

Flash applications call scripts ( _login.php : vc_login.php, lb_login.php, r_login.php …) to get start up parameters, user information (grant access), update user status.
These can be integrated as needed with site logic.
In example the login script could check cookies/sessions depending on site authentication type and allow user to access if logged in. Also this could populate username, gender and user permissions depending on user type.

The flash applications can also be embed in any html pages or templates for 3rd party scripts and some parameters like room name can be passed via a swf parameter like .swf?room=Test . Then flash will call the external scripts like login script where integration can be done as mentioned above.

ONLINE SESSIONS

The applications can show timer/credits info and also communicate with scripts enabling access/disconnecting users as needed but logic must be implemented by site developers.
This can be used for keeping lists of online users, getting and controlling user time online.

If you want to integrate this functionality in your custom projects see php edition pages and references to the _status.php scripts for each.

Sample: Implementing an online channels list for Live Streaming

The php edition does not use any sql tables so you can easily install it and integrate with a database system of your choice.

You have to build the online channels list same way as it’s done for Joomla and WordPress:

Each broadcaster application calls lb_status.php (about each 10s depending on connection) . You need to add channel name to an online broadcasters table (mysql). If already there update access time to current time. Delete all rows that were not access recently (last 30s) because these users must have disconnected.

Here is how it’s done for wordpress integration:

$s=$_POST['s'];
$u=$_POST['u'];
$r=$_POST['r'];
$m=$_POST['m'];

$ztime=time();

$sql = “SELECT * FROM $table_name where session=’$s’ and status=’1′”;
$session = $wpdb->get_row($sql);
if (!$session)
{
$sql=”INSERT INTO `$table_name` ( `session`, `username`, `room`, `message`, `sdate`, `edate`, `status`, `type`) VALUES (‘$s’, ‘$u’, ‘$r’, ‘$m’, $ztime, $ztime, 1, 1)”;
$wpdb->query($sql);
}
else
{
$sql=”UPDATE `$table_name` set edate=$ztime, room=’$r’, username=’$u’, message=’$m’ where session=’$s’ and status=’1′”;
$wpdb->query($sql);
}

$exptime=$ztime-30;
$sql=”DELETE FROM `$table_name` WHERE edate < $exptime”;
$wpdb->query($sql);

This table is used:
CREATE TABLE `$table_name` (
`id` int(11) NOT NULL auto_increment,
`session` varchar(64) NOT NULL,
`username` varchar(64) NOT NULL,
`room` varchar(64) NOT NULL,
`message` text NOT NULL,
`sdate` int(11) NOT NULL,
`edate` int(11) NOT NULL,
`status` tinyint(4) NOT NULL,
`type` tinyint(4) NOT NULL,
PRIMARY KEY (`id`),
KEY `status` (`status`),
KEY `type` (`type`),
KEY `room` (`room`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COMMENT=’Video Whisper: Sessions – 2009@videowhisper.com‘ AUTO_INCREMENT=1 ;”;

Live Streaming v2 by VideoWhisper

admin — Fri, 11 Sep 2009 04:33:39 +0000

VideoWhisper.com upgraded the Live Streaming application bringing several improvements and optimizations requested by users.

Some of the improvements:

advanced webcam settings (change realtime resolution, framerate, audio rate)
fullscreen button for video watching interface
fullscreen on click for embedded plain video stream interface
generate updated jpg snapshots for each live stream
timers (displayed on each interface depending on settings) can be used to control access, integrate in pay per view systems
multiple new options and parameters passed from script side

Also some RTMP application improvements should be mentioned like external player support and live video archiving as FLV for the Red5 application.

Upgrades are available for download on VideoWhisper.com and do not involve any costs for free or paid licenses.

First edition available with the upgrade is the PHP edition. The rest should follow shortly.

Use JW Player to play VideoWhisper application streams

admin — Fri, 28 Aug 2009 01:35:12 +0000

With the latest VideoWhisper rtmp applications versions, webmasters can enable external player support (both for FMIS and Red5). This can be enabled from RTMP Application Settings.

You need to have allowPlayers=true for FMIS or acceptPlayers=true for Red5 . These settings are turned on by default.

This will allow playing a stream published by a VideoWhisper flash application like Live Streaming with an external player like JW Player.

Demo:

Publish a stream from Live Streaming Demo (i.e. Studio1) and then view it on JW Player. Update channel name in link if you’re using a different one.

Important: As latest VideoWhisper solutions also support P2P streaming, these need to be configured with alwaysRTMP=1 parameter in their _login.php or equivalent script so streams are always published to RTMP. Because of this, demo above is disabled (to prevent heavy rtmp usage on public install), but you can use sample code in your own installs.

Here is the code to embed JW Player:

include(“settings.php”);
$stream=$_GET['n'];
?>

urlencode($stream)?>.flv&streamer=&autostart=true” />

urlencode($stream)?>.flv&streamer=&autostart=true” />

Get Flash to see this player.

Also this code could be used for playing a Studio1 stream broadcaster with VideoWhisper Live Streaming. Make sure you have swobject.js and player-viral.swf in that folder.
