Created attachment 442628 [details] Crash Report from iPad Air 4th Gen I am having the exact same problem, same segfault at the same location on an iPad Air 4th Gen in Safari or Chrome. My webapp was working on iOS 14.x but after upgrading to 15.1 it crashes some time during WebRTC negotiation. I have noticed this only happens when using the front camera; the back camera does not have this problem. I have found that turning off the experimental flag "WebRTC Platform Codecs in GPU Process" in the Safari settings makes the app work again.

I have created an example that causes this crash. https://jsfiddle.net/o19c0wfe/4/

If I force VP8 to be used for WebRTC as in the example below, the crash no longer happens. https://jsfiddle.net/MitchTalmadge/crpfvnab/21/
