0
2 weeks ago
by admin in ,

At least Debian 5 (Lenny) required.

Checkout release:
cat /proc/version
uname -a
cat /etc/issue
cat /etc/debian_version

 

If system is not in English, enable that:
dpkg-reconfigure locales
export LANG=en_US.UTF-8

Update /etc/enviroment

You may need to reboot.

 

Update:
apt-get update

Install Subversion:
apt-get -y install subversion

Install tools to build your own Debian packages:
apt-get -y install dpkg-dev debhelper dh-make devscripts fakeroot

Install Java (accept sun license if applies):
apt-get -y install java-package
apt-get -y install sun-java6-jre
apt-get -y install sun-java6-jdk
java -version

Install Apache Ant:
wget http://www.apache.org/dist/ant/binaries/apache-ant-1.8.2-bin.tar.gz
tar zxvf apache-ant-1.8.2-bin.tar.gz
mv apache-ant-1.8.2 /usr/local/ant
export ANT_HOME=/usr/local/ant
/usr/local/ant/bin/ant -version

Download the latest development version of Red5:
svn co http://red5.googlecode.com/svn/java/server/trunk red5-trunk

Run ant to build red5:
cd red5-trunk
/usr/local/ant/bin/ant

Deploy red5:
mkdir /usr/local/red5
cp -R dist/* /usr/local/red5/
cd /usr/local/red5
chmod 755 red5.sh

Deploy your custom apps in/usr/local/red5/webapps .
In example VideoWhisper Red5 RTMP application needed to run VideoWhisper solutions.

Start Red5 in background:
cd /usr/local/red5
./red5.sh >> red5.log &

Verify the correct ports are being bound to:
netstat -ant

 

You need to restart red5 each time you add webapps to /usr/local/red5/webapps or change configuration.

Close Red5:
cd /usr/local/red5
./red5-shutdown.sh

Or kill Red5 processes:
ps aux | grep red5
kill $process_id

Then start it again:
cd /usr/local/red5
./red5.sh >> red5.log &

Playback RTMP with JW Player

2 months ago
by admin in , ,

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 .

Configuring Flash Live Video Streaming Applications

11 months ago
by admin in , ,

Measure connection capabilities

To configure flash applications streaming you will first need to determine the connections that most users will have. So test first with your connection and also request other users to test.

So let’s consider this situation determined by http://www.speedtest.net (measure speed to a server close to the location of your streaming server):
Download: 9.43Mbp/s
Upload: 0.49Mbps

This looks like ADSL (in this situation upload bandwidth is 20 times lower than total connection bandwidth).

0.49 Mbps = 502 Kbps (kilobits per second)
8 bits = 1 byte,  so that means you can upload with 62 kb/s  (kilobytes per second)

As you can see, usually, connection is the cause of quality and latency limitations. A server with 1000Mbps connection will theoretically be able to handle up to 2000 x 0.49Mbps streams, so the server is not the problem with your tests, unless you’re on a shared plan and other clients are maxing out the resources.

How to configure flash videochat applications?

Considering you also have to upload audio and other data on that connection, you could setup camBandwidth to 49152 bytes/s (allocate for the compressed video stream).
On chat systems buffering should be reduced to 0.1 so delays are minimized. On 1 way streaming systems, you can use higher buffering to increase fluency in case of connection turbulence.

Flash streaming applications vs Skype

Skype desktop application uses different technology than these web based applications limited by browser based flash technology limitations . Skype uses:
-  p2p connections between all users and also uses fast 3rd users as proxies (not using server – so if you are in the same local network with the other tester or with a 3rd skype client with better connection, it uses the local bandwidth)
-  better codecs to get better quality for same bandwidth (flash player currently encodes only h263 and external encoders must be used to encode h264)

Use JW Player to play VideoWhisper application streams

2 years ago
by admin in , ,

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>

JW Player Demo
