- set SDI 1 to full duplex
- set SDI 1 to external key
- set SDI 1's keyer level to 255
- Code: Select all
configuration->SetInt(bmdDeckLinkConfigDuplexMode, bmdDuplexModeFull);
keyer->Enable(true);
keyer->SetLevel(255);
And, the following returns true which confirms the card supports external key.
- Code: Select all
attributes->GetFlag(BMDDeckLinkSupportsExternalKeying, &supportsKeyer)
The result is I can see the video fill out of SDI 2, as I would expect. However, I am not seeing a key signal out of SDI 1. Any suggestions of what I could be missing?
When I set SDI 1 to internal key, the result is SDI 2's output is keyed over SDI 1's input signal. So, internal keying seems to work fine.
