I don't think my webcam does the highest resolution.

"View > Reload" gets you out.

Resolution are basically presets. Most cameras don't do 1920*1080, but getting the available camera resolutions takes a while and is hardly ideal with the current web technologies: https://webrtchacks.github.io/WebRTC-Camera-Resolution/

Maybe attempting to switch to lower resolution when one isn't working?

[arthurzenika]

lower resolutions work, no problem. Don't hack on this, it's not something I use extensively. Maybe just catch the error and avoid freezing.

[louis-ev]

Ok yeah, I didn't get that the window would basically freeze and be unusable.
Fixing this for next version. Thanks for the feedback.
