It seems that others have now encountered the change in how Windows 10 handles webcams after the Anniversary update. Many applications simply never try to go beyond 720p30, so it wasn’t clear to me how many people would be impacted by this change.
After my initial post about this on 8/4 I dropped news of the trouble in the related support forums for OBS, vMix, and Wirecast. My thought was that people involved in the production of streaming media could possibly be impacted.
How ironic that in the two weeks since there’s been a flood of complaints about the Anniversary Update breaking webcam access in Skype. It hadn’t occurred to me that Skype, a Microsoft product(!), would also be impacted.
