Linux PCs
If configured with the appropriate components, Linux PCs running Fedora or Red Hat
(on Firefox) can play MPEG-1, MPEG-2, MPEG-4, and WM streams. However, the
Portal Server must download Linux components to each-end user desktop before any streams
will play. This should only be performed by a system administrator. When you access the
Portal Server for the first time, you will see a message in the embedded player window
indicating that the appropriate plugins are not installed. See "Installing Linux Components"
in the Portal Server Release Notes for detailed instructions. On Linux PCs, Portal Server
functionality is the same as in Windows except that the
Add Video feature is not available.
Table 4 shows the stream types supported for each environment; Table 5 shows the
operating systems that are tested and supported. Note that there are certain performance
limitations in Linux environments; see the ETV Portal Server Release Notes for information
and recommendations.
