Although we don't support this type of set up directly, I will as some colleagues if anything has changed recently within GoToMeeting that may have affected the webcam feeds.
Today I have had another look, when opening the camera from Go-To-Meeting the LED goes on as well.
So it looks to me that Go-to-Meeting is able to access the camera.
We are having the same issue which is becoming a real problem when broadcasting live events and our attendees cannot see the presenter.
We have tried reinstalling the software, reinstalling the cam etc. and it is constantly shows as loading but doesnt ever switch on. However, if you go into the camera settings it will work in the preview box (but still doesnt work for the actual webinar)
I have found one way around it which is still a bit hit and miss but works sometimes. Instead of launching the webinar, go to 'practice webinar' and the camera works. Launch the live meeting from there and it works. Its worth a try.
I am hoping that Go to will be able to solve this one soon
The version is 10.14.0 Build 18962
The LED is active and camera keeps loading
is there more you need to see/ know?
