Flash Streaming

Select the streaming server that will be used to stream presentation playback content. Your choices include:

• • External Flash Server (can be either Wowza or Adobe FMS)
  • Internal Wowza Server (only available for existing customers who upgrade to EchoSystem 5.5)

External Flash URL / Internal Wowza URL

This setting defines the Base URL for the Flash application. The label on this setting varies, depending on your selection in the Flash Streaming setting.

If you selected External Flash Server as the Flash Streaming setting, this field is labeled External Flash URL.

• • Recent versions of Adobe's Flash Player require that both the application and the instance name be specified.
  • The External Flash URL is comprised of the following components: the RTMP protocol, the FQDN (fully-qualified domain name) of the Wowza or FMS server, the on-demand application name (echo), and a _definst_ pointer. For most External Flash Server installations, the _definst_ parameter is required at the end of the standard streaming server URL. The figure below shows an example External Flash URL.

If you selected Internal Wowza Server as the Flash Streaming setting, this field is labeled Internal Wowza URL and uses the host name of the ESS along with the on-demand application name (echo).

This setting defines the base URL for the Flash streaming of live webcasts. You must use a Wowza Media Server for live webcasting.

When using an External Wowza Server, the Live Flash URL should consist of the same elements as the External Flash URL above, but use the live application name (echolive) instead of the on-demand application name. For most External Flash Server installations, the _definst_ parameter is required at the end of the standard streaming server URL.

Example: rtmp://ess.echostate.edu/echolive/_definst_

When using an Internal Wowza server, the Live Flash URL uses the host name of the ESS along with the live application name (echolive). For example: rtmp://ess.echostate.edu/echolive

Flash Folder

The path of the directory where the Flash streaming content is going to be stored.

This may be a Windows UNC path, a Windows mapped drive, or a Unix-style path. If you use an external storage such as a SAN for this content, then the ESS service or daemon needs both read and write access to this directory. The Flash streaming server requires read access only.

This setting identifies the host name of the Wowza Media Server that will be streaming the live webcasts, if applicable.

When using an External Wowza server, the Live Streaming Server Host should be the FQDN (without schema or path components) of your Flash server.

When using an Internal Wowza server, the Live Streaming Server Host is the same as the host name of the ESS.

Real Media URL

This setting is only used with Apreso Classroom capture stations configured to capture video using Real. Required if specifying a Real Media streaming directory. Enter the Base URL to the Real Media server mount point.

Example: rtmp://realserver.institution.edu/echo

Real Media Folder

This setting is only used with Apreso Classroom capture stations configured to capture video using Real. Enter the absolute path of the directory where the Real Media streaming content is stored.

Apreso Flash URL

The ESS supports presentations created by the legacy Anystream Apreso Classroom 1.3.10 system.

This is the Flash base URL specific to content created by the Apreso Classroom capture stations. The Apreso-created content needs slightly different settings to produced optimized playback and, therefore, uses a separate Flash application.

When using External Flash streaming servers, this may be unique. For most External Flash server installations, the _definst_ parameter is required at the end of the standard streaming server URL. Example: rtmp://ess.echostate.edu/apreso/_definst_

When using the Internal Wowza server, the host name must be the same as that defined for the Internal Wowza server.

Windows Media URL

This setting is only used with Apreso Classroom capture stations configured to capture video using Windows Media. Required if specifying a Windows Media streaming directory. Enter the Base URL to the Windows Media Publish Point. Example: mms://windowsmedia-server.institution.edu/echo

Windows Media Folder

This setting is only used with Apreso Classroom capture stations configured to capture video using Windows Media. Enter the absolute path of the directory where the Windows Media streaming content is stored.
