I tried using Arc but it keeps saying that it needs to access my webcam. I've tried various possible solutions, but to no avail. How do I do this?
It sounds like you're trying to use the Arc video tool to record video from your webcam, but you're seeing something from Arc that suggests that it doesn't have access? Arc requires access to your camera in order to work, so you'll need to give it access when you get a prompt.
If you aren't seeing a prompt, it might be that your browser is automatically refusing the permission, and it needs to be set up to give Arc that permission:
Changing camera/microphone permissions in Firefox
Changing camera/microphone permissions in Chrome
(You can find Canvas Guides about Arc under the new name "Studio".)
I hope this helps, or at least gives you another thing to try!
Actually, I was working with a browser called Opera which I like far better than Chrome or Foxfire. However, I can't figure out how to get Arc to work on it so I went ahead and used Chrome, and I was able to get Arc to use my webcam and microphone. For just about everything else in Canvas, though, Opera works very well. Thanks for the help, though!
