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.

Details about these calls (including explanations for multiple parameters you can pass) are listed on the php edition pages from VideoWhisper website:

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 ;”;

You need to create 2 files in public_html of website where suPHP is enabled. A .htaccess specifying path to php.ini configuration and a php.ini with directives.

Example for account “account-name”. Make sure you update that in .htaccess content:

.htaccess

suPHP_ConfigPath /home/account-name/public_html

php.ini

register_globals = Off

Install GeoIP C API
Change 1.4.6 to downloaded version.

wget http://geolite.maxmind.com/download/geoip/api/c/GeoIP.tar.gz
tar zxvf GeoIP.tar.gz
cd GeoIP-1.4.6
./configure
make
make check
make install

Install PHP PECL extension

wget http://pecl.php.net/get/geoip
tar zxvf geoip
cd geoip-1.0.7
phpize
./configure
make
make check
make install

Find php.ini

php -i | grep php.ini

Enable extension to load in php.ini:

;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;
extension=geoip.so

You may need to restart HTTP server (apache) to apply changes.

Download Geo Lite City database

wget -N -q http://geolite.maxmind.com/download/geoip/database/GeoLiteCity.dat.gz
gunzip GeoLiteCity.dat.gz
mv GeoLiteCity.dat /usr/local/share/GeoIP/GeoIPCity.dat

For more accurate detection and production projects, buy the full GeoCity database from MaxMind.

This is a tutorial to enable video sharing support on Centos servers.

This should install ffmpeg, mplayer, mencoder, flvtool2, yamdi, x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid, mediainfo, mp4box, neroaacenc . These tools will enable on your server:

• video and audio conversion
• thumbnail generation
• FLV meta injection (flvtool2, yamdi)
• extra codecs (x264, theora, mp3lame, vorbis, ogg, faac, faad2, xvid)

This is functional and we update it each time we configure a new server.
Installation is done using the “root” account.

Attention: If you copy and paste commands below, make sure “-” are not converted to “.”.  If these get converted, edit “.” back to “-”. Some options use 2 * “-”.

Some prerequisites:

yum install gcc gcc-c++ automake autoconf libtool yasm git subversion
yum install zlib-devel libmad-devel libvorbis-devel libtheora-devel lame-devel faac-devel a52dec-devel xvidcore-devel freetype-devel
yum install libogg zlib-devel libtool

rpm -ivh  http://rpm.livna.org/livna-release.rpm

yum install yasm
yum install libogg libogg-devel libvorbis libvorbis-devel


The quick way to setup ffmpeg, mplayer, mencoder:

rpm -Uhv http://apt.sw.be/redhat/el5/en/i386/rpmforge/RPMS/rpmforge-release-0.5.1-1.el5.rf.i386.rpm

or if you have 64bit server

rpm -Uhv http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.2-2.el5.rf.x86_64.rpm

yum -y install ffmpeg ffmpeg-devel mplayer mencoder ffmpeg-libpostproc

Edit the /etc/ld.so.conf file and add the following lines:

/usr/local/lib
/usr/lib

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.

To test the video conference plugin just register an account on this website and click the video conference link from the right panel.

WordPress  Integration

VideoWhisper.com  setup a simple integration that uses the WordPress username to login existing users into the simple php only version of their video conference software – the edition easiest to customize and integrate with any website. If the user is not logged into WordPress a warning message is shown and the visitor can click that to get back to the main WordPress website for registration/login.

VideoWhisper also  included a plugin that provides a linking widget. You can use that or directly add a link to “http://www.yoursite.com/videowhisper_conference/” .

Installation Instructions

1. Copy contents of com_videowhisper_conference\fms_applications in zip file to your applications folder in your fms installation folder. This step is not required if you use their video conference rental with hosting or managed rmtp hosting plans.
2. Copy the files from the zip file including folder structure to your public website location.
3. Fill the fms application path in videowhisper_conference/settings.php.
4. Enable the plugin and link widget or directly add the link to the videowhisper_conference folder.
