Niagara SCX and SimulStream
Niagara SCX and SimulStream represent the perfect team of tools for maximizing resources for
encoding purposes. With just one capture card, you can encode a single source into multiple
outputs. Examples include using a single video that you can encode in Adaptive, Flash, MPEG-4,
and Windows Media. You can encode these simultaneously by using SimulStream. SimulStream
allows you to take a single input and encode in different formats and/or bitrates simultaneously.
Because there is only one input when using SimulStream, you establish each encoding output as
an encoder in the SCX Explorer.
Setting up a SimulStream session
To set up a SimulStream session:
1.
Connect to the Niagara SCX Encoder Manager service.
2.
Insert the desired encoder type you wish to run on the server.
3.
Enter a name to identify the encoder.
4.
Click on the video and audio input for this encoder on the Input tab.
Note: This could also be a file requiring conversion to a streaming format.
Use the same video input for each output. If you have multiple boards in the
system, select the same board for each output desired.
5.
Configure the video and audio settings, if needed, on the Video and Audio
Settings tab.
Note: Repeat steps 4 and 5 for each output, for example, Flash and Windows
Media. There is only one input but two outputs.
6.
Click on the output in the Output tab.
Note: On the second Output tab, establish the target audience.
Windows Media Encoder has only one output tab. It contains both the target
audience and information for saving the video to a file.
7.
If required, enter the author and copyright information on the Author Info tab
under the Streaming Options for the encoder.
8.
To view a preview of the video, click the View tab under the Streaming Options.
Note: Steps 7 and 8 are optional.
9.
Click Start on the Operations tab to begin encoding.
10.
To view the statistics for the encoding session, click Streaming Options.
11.
Click on the various tabs to see information about the encoding session.
