Linux PCs
If configured with the appropriate components, Linux PCs running Fedora or Red Hat
(on Firefox) can play MPEG-1, MPEG-2, and MPEG-4 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 3 shows
the stream types supported for each environment; Table 4 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.
