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 ;”;

For sites and integrations where additional security measures are required, VideoWhisper applications support login session check on RTMP side.

This is used to make sure no clients will be able to connect to rtmp server without having previously logged in with the _login.php scripts.
When a new client tries to connect to RTMP server with a session name, rtmp application will check on the web server if that client session exists. If web server does not confirm that client logged in, rtmp server will reject the connection. RTMP server will also check for a webKey that needs to be configured same way on rtmp and web server: this will prevent connections in case of web domain hijacking.
Notes
- This will disable connections from external encoders (ie. FMLE) and players (ie. JwPlayer) to that rtmp address, as these will not provide a session name to check for validity.
- Usually, each installation will require its own rtmp side that checks session info with that installation. Otherwise you will have to tweak scripts to check on all installations.

RTMP Configuration

RTMP side web session check is currently supported for Wowza rtmp side. Download latest version of Wowza rtmp side, deploy to your server and update these settings in conf/videowhisper-web/Application.xml :

…
<Properties>
<Property>
<Name>acceptPlayers</Name>
<Value>true</Value>
</Property>
<Property>
<Name>webLogin</Name>
<Value>http://installation_url/rtmp_login.php?s=</Value>
</Property>
<Property>
<Name>webKey</Name>
<Value>VideoWhisper</Value>
</Property>
<Property>
<Name>webLogout</Name>
<Value>http://installation_url/rtmp_logout.php?s=</Value>
</Property>
</Properties>
</Application>

 

 

Then restart WowzaMediaServer service. For troubleshooting check Wowza access logs. If errors occur in the error logs submit a ticket to VideoWhisper about this.

Web Configuration

Download latest Video Conference php edition and check these integration files:
rtmp.inc.php – stores session info when user authenticates from vc_login.php ; contains $webKey if you want to change it
rtmp_login.php – called by rtmp server to see if a session name is valid (authenticated); also gets canKick permission to allow user to kick clients
rtmp_logout.php – called by rtmp server when client with a session name disconnected (to cleanup session)

Configure settings.php to use the videowhisper-web rtmp address.

To integrate this on other editions or installations you will need to copy the 3 files mentioned above to installation folder and include rtmp.inc.php in the _login.php scripts that authorize the user.
Other changes could be required depending on particularities of each integration.

Sample Demo Configuration

Installation url: http://www.videowhisper.com/demos/vc_web
Using rtmp address: rtmp://videowhisper.com/videowhisper-web

         <Property>
<Name>webLogin</Name>

Downloading to computer and then uploading unzipped files by ftp is time consuming on ADSL internet.

Get download link from http://www.joomla.org/download.html .

Assuming installing for an account camcomm:

cd /home/camcomm
wget http://joomlacode.org/gf/download/frsrelease/16024/69674/Joomla_1.7.3-Stable-Full_Package.zip
unzip Joomla_1.7* -d public_html
chown -R camcomm:camcomm public_html/*

 

Then open website and follow installation procedure.

You can publish a rtmp stream to a rtmp address and then playback with an external player like JWPlayer.
If you publish StreamName to rtmp address rtmp://your-rtmp-address-here then you will need to configure JW Player:
var flashvars = { file: StreamName.flv, streamer: rtmp://your-rtmp-address-here, autostart:”true”, type:”rtmp”}

Webcam video streams can be published from web with a video Live Streaming broadcasting script. With the VideoWhisper Live Streaming soulution, StreamName is channel name (in example Studio586). 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 server.

If you want to publish for other devices special encoders and codecs would be required. Using an external encoder you can encode with codecs and settings not available in browser flash player (due to flash limitations). Not all encoders and versions are compatible with all rtmp servers and versions. Some require special configuration and usage instructions.

Adobe Flash Media Live Encoder can be used for Adobe Media Interactive server and is also reported to work with Wowza.

Wowza & Wirecast documentation and support is available for Wowza Media Server hosting.

Note that when publishing H.264, video player should be configured to play StreamName.mp4 instead of StreamName.flv .

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

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.

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'];
?>
<object id=”player” classid=”clsid:D27CDB6E-AE6D-11cf-96B8-444553540000″ name=”player” width=”328″ height=”260″>
<param name=”movie” value=”player.swf” />
<param name=”allowfullscreen” value=”true” />
<param name=”allowscriptaccess” value=”always” />
<param name=”flashvars” value=”file=<?=urlencode($stream)?>.flv&streamer=<?=urlencode($rtmp_server)?>&autostart=true” />
<object type=”application/x-shockwave-flash” data=”player.swf” width=”328″ height=”260″>
<param name=”movie” value=”player.swf” />
<param name=”allowfullscreen” value=”true” />
<param name=”allowscriptaccess” value=”always” />
<param name=”flashvars” value=”file=<?=urlencode($stream)?>.flv&streamer=<?=urlencode($rtmp_server)?>&autostart=true” />
<p><a href=”http://get.adobe.com/flashplayer”>Get Flash</a> to see this player.</p>
</object>
</object>

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.

<script type='text/javascript' src='swfobject.js'></script> <div id='mediaspace'>This text will be replaced</div> <script type='text/javascript'> var so = new SWFObject('player-viral.swf','mpl','320','320','9'); so.addParam('allowfullscreen','true'); so.addParam('allowscriptaccess','always'); so.addParam('wmode','opaque'); so.addVariable('file','Studio1.flv'); so.addVariable('volume','5'); so.addVariable('streamer','rtmp://your-rtmp-server/videowhisper'); so.addVariable('autostart','true'); so.addVariable('quality','false'); so.write('mediaspace'); </script>
