Index of the external video renderer to use

Remarks

Default value: -1 (the first card will be used)

This feature is useful when more than one external video renderer are installed, to specify what renderer should be used.

E.g. let's suppose a PC where 4 Blackmagic Decklink cards are installed:

e.g. to select the 1st Decklink card:VideoGrabber.VideoRendererExternal = vre_BlackMagic_Decklink

VideoGrabber.VIdeoRendererExternalIndex = 0

e.g. to select the 2nd Decklink card:VideoGrabber.VideoRendererExternal = vre_BlackMagic_Decklink

VideoGrabber.VIdeoRendererExternalIndex = 1

etc...
