Tab
Description
 Enter a file destination in the provided field.
 Remember the encoder system references the file name and not the system
running SCX Explorer.
 Always start your browse for files at My Network Places and work down or
enter the entire file pathname beginning with the system name when
Niagara SCX and SCX Explorer reside on different computers.
 If you simply enter a file name, you may inadvertently browse your local
computer when the media file resides on the remote computer.
 Set the output destination on this tab under Save to File.
 Save the stream to a RealNetworks
®
server for live streaming.
 Select Enable Streaming to stream your MPEG-4 content.
NOTE: Selecting Enable Streaming disables the Save to File option.
 Adjust the port settings as required.
NOTE: You most likely do NOT need to change the default settings.
Default settings enable multicast streaming. To disable multicast streaming, change the IP
address for the Destination to the IP address of the server you want to use to stream to from
the encoder.
 Enter a stream name in the Stream Title field.
 Note any additional information in the Stream Info field.
 Enter a required name and destination path for the resulting SDP file the
system created when it started the stream in the Save sdp file field.
 Refer to online documentation or message boards for setup details specific
to individual stream servers if you stream to a Helix®, Quicktime®, or
Darwin® server.
NOTE: You can stream point-to-point by selecting a share destination directory for the saved
SDP file.
Remember to disable multicasting by entering the IP address of the computer where you
want to send the stream in the Destination field.
 For example, save the SDP file to a shared folder on the local drive if you
want another computer to view the stream.
 The other computer can open the SDP file and play the stream in Quicktime
or other MPEG-4-compatible streaming player.
 Developers recommend that you avoid trying to view the stream on the
same system where the Niagara SCX encoder resides unless you have a
powerful system (dual-core processors or better) since MPEG-4 encoding
can be CPU intensive.
 Doing so may overtax the host CPU, cause video quality degradation, and
