Allow Multiple Instances of Each Filter
This control enables you to run multiple application instances on one device that does not have
device select controls.
ViewCast recommends that you do not allow multiple instances of each filter unless you have a
specific need for it. Turning it on affects some of the above description. Specifically, you cannot
keep crop, watermark, and caption settings separately for applications sharing a filter, and
might confuse and interfere with each other. The most recent crop, watermark, or caption
setting corresponds to the saved one – it overwrites settings that you might previously have
saved from another application.
This global setting affects all the Osprey 2XX, 300, 400 or 530/540/560 devices as a group.
When you apply this change, a message box prompts you to restart the system. This change
does not work correctly until you do so.
Deinterlace, inverse telecine and gamma correction when set, affect all SimulStream instances
on that specific Osprey card. In other words, all filters on the device and must have the same
settings.
You can set crop, watermark, and caption settings differently for each pin of each filter. The
driver also saves settings between sessions separately for each filter.
You can set video size, color format, and frame rate differently for each pin. The application
must save these settings.
