The checkbox at the top of the group, when checked, enables SimulStream to run for the currently
selected device.
All Niagara appliances include a full SimulStream license installed for each A/V channel, and this
checkbox controls full SimulStreaming.
When you change the SimulStream Enable status and click Submit, it is strongly recommended you
restart the appliance. If you do not, SimulStream may become partially active, but the filters may be
incorrectly named, and their pins may be incorrect.
Show filters per device
With this control, you can set the device driver to expose 1 to 10 filters per device for enumeration
and selection by encoders. If, for example, 4 filters per device are chosen, device lists in applications
will show four entries for the currently chosen device. For device 1, they are designated as 1.1, 1.2,
1.3, and 1.4.
The number of filters you request will not display or work correctly until the system is restarted.
NOTE: While it is possible to expose and enumerate up to 10 filters per device, the practical number
of working filters will be less. The practical number of filters depends on the capability of the
appliance, the types of filtering enabled, the types of scaling and color format conversions requested
per encoder, and the type of processing being done. If the appliance has multiple capture channels,
the number of filters is the total across all channels. In addition, some types of processing, such as
deinterlacing and gamma corrections, which are performed once per channel may, in this case, occur
multiple times. In summary, an appliance can support 5, 6, or more concurrent filters on one device
if the processing per filter is light. However, only 2 or 3 simultaneously running filters can be
supported if the processing load inside or outside the driver is particularly heavy.
