Silverlight Tab Settings:
Silverlight mode supports Live Streaming Mode and VOD archival mode. xCoder determines which type
of mode to use by the extension name of the Publishing point. "isml" extension is used for live streaming
and "ssm" extension is used for VOD.
•
Publishing Point Silverlight streams are published over HTTP to a Microsoft Smooth Streaming
compatible server using a configured publishing point that is identified by a .isml file on the server
and a URL pointing at this file. Please consult the user interface and documentation for your
streaming server in order to create the publishing point and identify the URL.
Example: To publish to Microsoft IIS located at 192.168.1.101 and configured with a publishing
point located at
http://192.168.1.101/test1.isml , the Publishing Point field for Stream Group 1
should be set to http://192.168.1.101/test1.isml .
Be sure to use different publishing points for each stream group.
•
Authentication: The HTTP protocol defines a number of authentication methods. xCoder
supports no authentication, basic authentication, and digest authentication. The authentication
method and username and password should be specified here. Please consult the user interface
and documentation for your streaming server in order to determine authentication requirements.
Example: Akamai requires HTTP Digest authentication so, to publish to Akamai, you must
selected “Digest” authentication and enter the appropriate username and password.
•
Fragment size: The fragment duration in seconds typically set to 2 for live streaming.
In order to play a channel on a player, a Silverlight player and manifest URL are required. The manifest
URL will be of the form
http://host/path/file.isml/Manifest . In many cases, this will be the above Publishing
Point with /Manifest appended. In some cases, such as with Akamai, a different Publishing Point URL
may be provided for the player than for the streaming encoder. Please consult the user interface and
documentation for your streaming server in order to determine the correct player URL.
Example: In the prior example of publishing to Microsoft IIS, the manifest URL required by a player would
be
http://192.168.1.101/test1.isml
/Manifest!
xCoder comes installed with an evaluation Silverlight player. To use this, install the Silverlight plug in on
a windows machine and point the windows machine browser URL to
http://xCoder-IP-ADDRESS/silver.html?file=<your
!manifest!URL>!
Example:
http://xCoder-IP-ADDRESS/silver.html?file=http://192.168.1.101/test1.isml
/Manifest!
In order to publish to a streaming server that is located on the internet, xCoder must have outgoing
network access over HTTP and must have HTTP POST chunked encoding capability. This may require
proxy/firewall configuration changes.
