Webcam Not Working on Mac #959

Open Draeorc opened 4 years ago

Draeorc commented 4 years ago

After successfully launching Grip, I tried to add a webcam source in the 0 slot. I also tried the other slots but they didn't work either.

Thread[JavaFX Application Thread,5,main] threw an exception

Stack Trace:

Can you try the version on master?

I am experiencing a similar issue too with Grip v 1.5.2 on Mac OS 15.5.5 (Catalina)

@srajanpm can you also try running the code from source and see if that helps?
