@HeshamMeneisi can you check if navigator.mediaDevices.getUserMedia() is available?

[HeshamMeneisi]

@thijstriemstra Just checked on Epiphany and mediaDevices is actually undefined. But shouldn't that produce an error?

[thijstriemstra]

did you define an error handler?

[HeshamMeneisi]

@thijstriemstra Yes but it logs on dev and I even completely disabled it and still nothing was printed. Is there actually any handling for browsers not supporting MediaStream? On iOS Safari, it actually opens the camera but then fails to record. I will open a different issue for that when I get to see the logs from an iOS device.

@HeshamMeneisi I think you meant navigator.mediaDevices.getUserMedia(), and no, the handling is done using the webrtc-adapter library, as you can see in all the examples. Can you doublecheck if you included it?

On iOS Safari, it actually opens the camera but then fails to record. I will open a different issue for that when I get to see the logs from an iOS device.

What version of iOS? Did you try with latest iOS 14.4? Also, make sure to test the examples in the docs, don't include custom code.

I am not able to reproduce this with Mobile Safari on iOS 14.4. Chrome on iOS 14.4 produced a 0kb file while recording though..

Need to test this again with iOS 14.5.
