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 .

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)

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

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

  That means streaming can use as much bandwidht as available per plan and there are no limitations for the number of simultaneous connections (other that server load).
• Dedicated IP
• Managed setup of Red5 application
• 1 Free Script Installation
  Limited to datetopia, videogirls, videowhisper scripts only.
• CPanel
• Setup of RTMP application

You can also check Red5 Hosting on Videowhisper.

The VideoWhisper Live Streaming software can now be easily used to add video broadcasting to WordPress sites and live video streams on blog pages.

To test a live demo of software on WordPress, just register a free account on this site and use the widget link from the right menu to start broadcasting.

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. We also included a plugin that provides a linking widget. You can use that or directly add a link to “http://www.your-site.com/videowhisper_streaming/” .

The widget also displays online broadcasters and their show names.

The watch screen logs in wordpress logged in users by adding a @ at end of username (so broadcaster can see & test his own video as a different user). Blog visitors will be able to participate in chat by providing a temporary username right in the chat application.

A free version of this component can be downloaded for free from the WordPress Live Streaming Software page.

January 2009 Updates:
+ New dark themed template added: VideoGirls Dark;
+ Performer ID verification including photos;
+ Video recordings on profile page;
+ Updated live video streaming on profile page and live preview on chat page;
+ Targetted registration links for each user category (member, performer, operator, affiliate);
+ More demo videos showing the features.
