WARNING! If you enable or disable SimulStream after you save an encoder profile could disable the
profile you saved.
For instance, if you save a profile using Capture Device 1, then enable SimulStream, SCX no
longer recognizes Capture Device 1 but sees Capture Device(s) 1.n instead.
You see a red X designating a non-recognized capture device by that profile and must reselect
your input device to Capture Device 1.n to clear the red X and use the profile.
Filters
From a practical point of view, filters have two interrelated purposes:
1. They allow applications to enumerate and list DirectShow video capture and preview pins or
streams (each with different settings) as named entries in their video device select list.
• You can set up the driver to show 1 to 10 filters per device.
• Each filter has one preview pin and one capture pin.
