Setting the Registry for RealNetworks Encoding
Setting the Registry for RealNetworks Encoding
If you want at least one of your secondary streams to be in RealNetworks format,
select the
RealEnabled
encoding option in the
DualEnc
Registry table. When this
feature is turned on, your encoding session will result in a primary MPEG-2
stream and a secondary stream in RealNetworks format. It can be encoded in SIF
(352 x 240/288) or QSIF (176 x 120/144) resolutions, as defined in the
DualEnc
Registry table, with QSIF requiring less CPU usage than SIF.
One useful feature of producing a secondary stream in Real format is that the
stream can be displayed during the encode as a confidence monitor on your Argus
encoder screen, using the RealPlayer application. To enable this feature, just set
the
PreviewEnabled
flag, described in the table below, to 1.

Turning on the dis-

usage. You may need
to adjust other
parameters to
accommodate.

TRUE (1) if the Real
stream is to be stored
on the local drive.

file is to be created.
If set to 1, define the
path name of the
local file in Filename.
