Some java optimizations to add in red5.sh :

export JAVA_OPTS=”-Xrs -Xms128M -Xmx256M -Dsun.rmi.dgc.client.gcInterval=300000 -Dsun.rmi.dgc.server.gcInterval=360000 -Djava.net.preferIPv4Stack=true -XX:+ExplicitGCInvokesConcurrent -XX:+UseConcMarkSweepGC -Xverify:none”

Assuming red5 was installed in /opt/red5/dist admin will often need to restart it or check if it’s running.

Make sure Red5 restarts: restart.sh

#!/bin/bash
#Restart the process
#First see if running
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v restart | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
cd /opt/red5/dist
if [ -z "$PID" ]
then
#not running
echo “Red5 was not running at `date`” >> /opt/red5/dist/run-restart.log
else
echo “Red5: $PID”
#shutdown
/opt/red5/dist/red5-shutdown.sh
sleep 6
#make sure
kill $PID >> null
sleep 2
fi
#start
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “On request restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log

Mare sure Red5 process is running, if not start it: running.sh

#!/bin/bash
#set environment
PID=`ps -eo ‘tty pid args’ | grep ‘red5′ | grep -v grep | grep -v running | tr -s ‘ ‘ | cut -f2 -d ‘ ‘`
if [ -z "$PID" ]
then
#Restart the process
cd /opt/red5/dist
/opt/red5/dist/red5.sh >> /opt/red5/dist/red5.log &
echo “Restarted Red5 at `date`” >> /opt/red5/dist/run-restart.log
else
#do nothing
echo “Red5 is already running with PID=$PID at `date`” >> /opt/red5/dist/run-checked.log
fi

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 . These tools will enable on your server:

• video 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.

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.

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>
