I created a project last year that integrates live video from my Decklink 4K SDI card, into a .NET project. At the time everything worked great, and I finished the software and set it aside.
Fast forward to now, and I'm ready to finally use the software..... except now I've run into a fatal roadblock:
When trying to access the live video, it seems the Blackmagic WDM Capture filter is already in use.
To trouble shoot, I've tried the following:
1) To make sure it's not my custom software that's causing the problem, I rebooted the computer, and opened GraphEdit, and tried to add the Blackmagic WDM Capture filter. It fails, and says "The filter could not be created. Resources used by this filter may already be in use. Access is denied. (Return code 0x80070005)".
2) I ran the Black Magic Media Express software, and I can see the live video just fine.
Any ideas? This project has taken two years to develop, and my entire life savings. The software is a critical component, and suddenly it's not working, which is causing me great stress. Any help would be greatly appreciated!
