Viz Engine Administrator’s Guide

The streaming input service gets started if at least one input channel is set to
“STREAMING” in Viz Engine’s configuration file (or “active” in the Video Input section).
For the streaming output service the StreamOut.Enable flag in Viz Engine’s
configuration file has to be enabled (StreamOut.Enable = 1).
If the startup process or the initialization of a streaming service fails Viz Engine will
disable the streaming input or output. Hence, if initialization fails, it is not possible to
re-/start the services manually.
If you run Viz Artist without a video card, output streaming will only start when Viz
Artist is in On Air mode with Preview enabled (see On Air Mode). When Viz Artist is not
in On Air mode or the Preview is hidden, output streaming will not start or will freeze till
the Preview is visible again.
This section contains the following procedures:
• To enable and configure streaming of Viz Engine’s output
• To control the input stream
• To control the output stream
To enable and configure streaming of Viz Engine’s output
Note: Always make a backup of your configuration file before changing it!
1. Copy a default profile XML (e.g. HD_mpeg2_MP@HL_30Mbit_longGOP.xml)
and paste it into the Viz Engine program directory (i.e. C:\Program Files
(x86)\vizrt\Viz3)
2. Open your Viz Engine configuration file, locate the STREAMING_OUT section
3. Set StreamOut.Enable to 1
4. Set StreamOut.Profile to match the filename of the profile XML
5. Save the configuration file
6. Start Viz Artist
Note: Default profiles can be found in the Viz Streaming program folder (e.g. C:
\Program Files (x86)\vizrt\VizStreaming 3.6)
