Decklink recorder 4k with GotoMeeting & Polycom

PostMon Mar 20, 2017 1:59 pm


i've two cards (mini recorder 4k) and they don't want to work with Goto Meeting and Polycom Realpresenter Desktop.

I have an input from a videomatrix and it comes with a 720p 60Hz signa

In both apps i can choice between "Blackmagicdesign WDM Capture" or "decklink wdm capture".

If i try the first option, i get a failure that the device is already in use" and with the other one i get a black screen inside the app.

With media express i get a picture. So i think its a problem in my configuration. What can i try?

Are the settings in "media express" global settings?

Sorry for my bad english.

Regards Martin

Common problem.!! the WDM drivers mostly don't work..

Same applies to Google Hangouts, Skype and all other non broadcast programs that don't have Native BMD hardware support.

You need a piece of software to act in between.. I did that with Google Hangout to run it trough wirecast lite.. But not sure if the same technic applies to your software..

Decklink cards are pretty rough with such software, in my experience. The Web Presenter is a good candidate here, I think.
