Decklink SDI card to WDM capture is black on Win 10

PostSat Oct 19, 2019 6:20 pm

I have 2 systems running Windows 10 pro. They both have Decklink SDI cards in them.
Media express and OBS both see video from the SDI input (testing at 720P59.94).
The WDM Capture device only shows black when accessed from Skype, Google Hangouts, Goto Meeting and Zoom. I even tried it with VLC and it is still black.

A few months ago this worked, then it died after updates, then yesterday when trying different updates it worked once and then went blank again.

For testing I also have connected a USB webcam and the programs all see that just fine.

Windows is up to date as well as BMD Desktop video at 11.4.1.

Before I spend all day downgrading drivers and such, are there others out there with the same issues who have found the right combo of driver versions?

My next test is to find my Magewell dongle and try that.
