Camera not working with IOS and Safari browser

[huynhthanhnhan]

My English is not good, hope everyone sympathize!
I am trying to run this demo with IOS version 13.3 and the Safari browser.
https://kalwalt.github.io/kalwalt-interactivity-AR/nft/nft_cesium.html
The situation is that after 'allow' the camera, the screen is captured and the video cannot be played. If I switch back to the main screen or another tab and come back, the video will play normally.
With Android and Windows devices, everything is fine. I don't know if this is an error due to camera permissions on IOS or some other problem.
Looking forward to the help, thank you everyone.

Hi @huynhthanhnhan thank you for reporting this! Unfortunately i haven't an iOS device to test but definetely seems an issue with iOS. i will re-post this issue on the kalwalt/jsartoolkit5 for a better support. Let's continue the discussion there.

Reported back here because i think it's specific to examples posted here.

What is the result with this https://kalwalt.github.io/kalwalt-interactivity-AR/nft/nft_pinball_image.html instead?

Hi @kalwalt thanks for your respond.
I have just checked with the link above but the result is still the same.
There are a few details we can consider that when allowing the camera, the first picture was taken proving that the camera was turned on but after the video did not continue, I tried debugging the process and rendering loops continued running. I think it is possible that our video has been blocked by some process or is not in focus because when opening another application or returning to the home screen and returning to the demo, video and everything works normally again. Do you think the problem is related to ThreeJS objects like Texture or scene, camera, etc.?

Hi @kalwalt ,
I tried more on two iOS 13 devices and failed but with one other iOS 12 device everything was fine. I have not tried it on IOS 11 but it seems this is really a problem of IOS 13. Thank you very much for your help ^^!

@huynhthanhnhan As i remember we had a similar issue in Ar.js, i think the problem was that getUserMedia do not choose the right camera (or a camera that not exist in the device), but i can't be sure because i can not test sorry! I would also post or link this issue also on the artoolkitx/jsartoolkit5 issue tracker, because other users may encounter this issue.
