• Standard applications can access a particular filter without any custom programming
specialized for Osprey devices.
2. Each filter has independent settings for cropping, default output size, watermarks, and
captions that you can store between sessions.
NOTE: Compared to the previous pin-based method, no requirements exist for a particular
startup order, to associate settings with instantiations.
If you are familiar with GraphEdit, you can best visualize SimulStream filters where you:
• Construct a multifilter graph with GraphEdit
• Apply different crop, watermark, and caption settings to each filter
The Enable Checkbox
The checkbox at the top of the group (Figure 148) turns on SimulStream for the currently selected
device. Table 23 indicates the conditions for SimulStream.

When… Then…
You have a full SimulStream license installed This checkbox controls full SimulStream.
You have a SimulStream license installed but
have not turned SimulStream on
The text shows SimulStream as enabled.
You have no purchased SimulStream license This checkbox controls SimulStream evaluation
mode.
You uncheck the Enable check box The text line at the top of the control group
indicates an installed SimulStream evaluation
mode.
You check the Enable check box The text indicates that SimulStream evaluation
mode is enabled.
A message box prompts you to restart the system when you change the SimulStream Enable status
and click Apply or OK. ViewCast strongly recommends that you do so. If you do not, SimulStream
may partly work but the filter names and their pins may remain incorrect without a restart.
When you enable SimulStream (or SimulStream evaluation mode), the driver always works in
Postprocessing mode, as described in the mode control group. In this case, the system forces the mode
control to Postprocessing mode and disables the Direct mode control.
