VideoWhisper RTMP Web Session Check

1 week ago

by admin in Scripts, Security, Servers, Video Chat, Video Streaming

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>

Setting up VideoWhisper RTMP on Influxis

1 month ago

by admin in Servers, Video Chat, Video Streaming

If you have a FMS account with Influxis, use these instructions for setting up a new application:

1. Create application from Tools > New App Builder or My Applications > Add New Application. Use any name i.e. “videowhisper” and save generated rtmp path.

2. From Tools > File Manager / File Admin edit videowhisper/main.asc file and make sure it has the contents of videowhisper/main.asc (open it with notepad or other text editor). If needed select all from text editor (CTRL+A), copy (CTRL+C), move to form, select all from there (CTRL+A), paste from clipboard (CTRL+V).
Get VideoWhisper FMIS rtmp side from Downloads : RTMP VideoWhisper Applications > FMIS .

3. From Account Settings > Domain Permissions, Set Referring Domain(s), Add New Domain – add your domain that hosts the flash (i.e. your-domain.com)

4. Reset the VHost for your Influxis account so it loads new applications or updates.
In your Influxis account go to My Applications > FCS Administration Console: Connect then go to Maintenance : Adaptor / VHost: Restart .

Playback RTMP with JW Player

2 months ago

by admin in Scripts, Servers, Video Streaming

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 Servers, Video Chat, Video Streaming

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)

Red5 Linux Server Optimizations and Tools

1 year ago

by admin in Servers, Video Streaming

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

Install ffmpeg mplayer flvtool2 yamdi x264 theora mp3lame vorbis ogg faac

2 years ago

by admin in Servers, Video Streaming

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 yasmyum 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
