Hi Shilpi,

By default the GdiKeyer sample outputs internal key - where the key frame is blended on the input stream on a full-duplex device. To change this sample to fill/key mode - where pair of connectors output the fill and key - please make the following change to code:

GdiKeyer.cpp|line 392:
Code: Select all
//deckLinkKeyer->Enable(false);                     // Enable internal keying
deckLinkKeyer->Enable(true);                     // Enable fill/key keying


Regards
Cameron
