Chapter 6: Video Driver Topics
When “Optimize for Single Streams” is selected,
the Osprey driver is configured for minimum
cpu usage and bus bandwidth utilization when
possible. It switches to more cpu-intensive
SimulStream processing only when additional
pins start running.
When it does make this switch, there could be a
slight transition in the appearance of the video.
In this mode you have the option to run with
Software Deinterlace either enabled or disabled.
When “Optimize for SimulStream” is selected,
the driver always runs in SimulStream mode,
and will use more system bandwidth to do
so if necessary. With this setting, Software
Deinterlace is always turned on, and the
Software Deinterlace control is disabled.
It is recommended that you use the Optimize for
SimulStream setting only when you are actually
running multiple video capture pins. There is no
quality advantage, and some system bandwidth
penalty, when you are running just one stream.
Changes to this control take effect when you
restart the application.
Multiple Capture Pins Per Process
A few applications do not work correctly when
they see multiple capture pins on the same
device. Specifically, RealNetworks Helix Producer
Plus 9.0 has a known problem.
When you select the “No” setting, only one
capture pin is visible to each application instance.
You can have multiple applications, each with
one capture pin, including multiple instances of
the same application. But a single instance of an
application is not allowed to use more than one
capture pin.
When you select “Allow”, each instance of each
application can have multiple capture pins.
This control does not affect the preview pin.
Applications can always use one preview pin in
conjunction with one or more capture pins.
Changes take effect when you restart the
application.
