Installing the SmartClient Service
Installing Live Smooth Streaming
To install Live Smooth Streaming of still recording files:
1 Firstly, download IIS Media Services 4.1 64bit from
http://www.microsoft.com/download/en/details.aspx?id=27955
2 Install this on your IIS Server.
3 Install SmartClient.
If SmartClient is already installed, run the SmartClient Installer from the ITX
Install\PostInstall\SmartClient Installer folder.
Correcting the MIME type listed in web.config
There is a known issue with installing Live Smooth Streaming after IIS has already been
installed for a standard SmartClient setup. When you attempt to start the Live Smooth
Streaming service from the IIS Manager, it fails to start. This is due to a problem with a MIME
type listed in the
web.config file.
To fix this problem:
1 Navigate to C:\inetpub\wwwroot and open the web.config file with notepad.
2 Remove the line.
3 Restart the service from the IIS Service Manager.
SmartClient Install will then create the new directory structure for the Smooth Streaming
media files to be written to by the Encode service. The files are written to the following
location:
C:\inetpub\media\archives\DEFAULT WEB SITE\LSS\clipname\date and time
created\segment001
This can be reconfigured to a different location, such as a larger storage drive on the IIS
server rather than the system drive. Although a remote location on the network can also be
chosen, it is not recommended that you do this as Live Smooth Streaming has only been
tested using locally attached storage. Please see the section below for details on how to
change the Smooth Stream files’ location.
A number of separate files are created for each recording that are composed of video
(.ismv), audio (.isma), caption data (.ismc) and a metadata header/reference file (ism
extension).
These are combined (or ‘muxed’) when streamed over http to create a single media stream
which can be browsed or annotated as required.
The Smooth Streaming Publishing Point directory contains a pointer file with the same
name as the clip being recorded, which references the actual files detailed above.
Reconfiguring Live Smooth Streaming media files’ storage location.
Note: Changing this configuration on a live system will cause LSS media
files to be left behind in the C:\inetpub\media\archives when Assets
are deleted. These will need to be manually removed.
To change the path where the smooth stream video files are stored:
1 Using Windows Explorer, browse to the current storage path and change its properties
to being unshared.
