This is a duplicate of #1710 and is currently tracked in the known browser bug issue in #1059. Can you try to pull this branch to see if it works for you https://github.com/aws/amazon-chime-sdk-js/tree/ios-15.1-fix ?

@ltrung We tested the ios-15.1-fix branch and were still able to reproduce the issue. I'm attaching our logs.

Did the user turn on content share or video?
In the log I saw this error message from content share which likely the cause of the crash. Content Share does not work in iOS since they do not support the webRTC screen capture API getDisplayMedia

I confirmed that they are turning on the camera. We just tried another test in the browser demo application, making sure that he clicked the Camera icon

As far as our application goes, we detect mobile devices and disable the Screen Share button.

We are also testing the fix. Seems to be working for us if and only if Request Desktop Website option is disabled.
By default all iPads have this option turned on.

[ltrung]

@rachinkapoor Thanks. So this is indeed the same issue as #1710 as I mentioned above. We disabled H.264 for now for iOS 15.1 device based on user agent but i guess when iPad has Request Desktop Website on, the user agent will be Mac Safari and not iOS thus, we did not do the workaround.

As a workaround, can you retry the code here e15565d#diff-12999dcd6545b6debd7a9cb6c9a75abb4982bf367947a9a2e97fbc87c1aa1e10R41 and update this to include Safari also e15565d#diff-878aade3f1ff249700b52b8c36f7715a1fd27b4f73344d55072e08aae78b8608R277

[ltrung]

Updated the code in the branch https://github.com/aws/amazon-chime-sdk-js/tree/ios-15.1-fix to include Safari and iPad 15.1.
Can you give it a try?

Hi Team,

We are waiting for the issue to be fixed. It's creating problems with the iPad and now iPad users cant able to use the application for the past 9 days. We are expecting a quick fix asap.

[ghost]

Still have not understood if this issue was fixed or not.

[dchen-aws]

@karthi-manoharan @BissacM this branch contains a fix for Chrome and Safari on iPadOS 15.1. The fix is not pushed to NPM yet.

[pgutierrez-bcov]

Tested the latest from master as it seems that the fix has been merged and we were still able to reproduce this on iPadOS15.1. Works fine on iOS15.1

[ltrung]

It worked fine for me on iPad iOS 15.1.0. Could you attach a console log?

[dchen-aws]

Tested the latest from master as it seems that the fix has been merged and we were still able to reproduce this on iPadOS15.1. Works fine on iOS15.1

and which browser are you using?

[ezramorse]

Please bump npm to 2.22.0 Thanks

[karthi-manoharan]

Hi @ltrung

Chime SDK Version: 2.23.0
Brand: Ipad Mini 5th Gen
OS Version: IPad 15.1
Browser: Brave 1.32.1(21.10.28.15)

issue still exists. Can you please try this browser and test it.

[ltrung]

Double check and verified that I could turn it on in my iPad Pro.
@karthi-manoharan Notice that you use Brave browser which is not currently supported. The core issue is that iOS 15.1 has a bug with H264 video encoding so we need to disable it for certain browsers based on user agent and since we do not support Brave, we did not include it. To support this for Brave, you would need to modify this function to add Brave.

[karthi-manoharan]

@ltrung
As per iPad, I can able to debug only the Safari browser. I cant able to debug and get the console log for the brave browser. Can you please help me to find out

[ltrung]

@karthi-manoharan Please refer to my previous post but we do not currently support Brave information.

[karthi-manoharan]

Thanks @ltrung

The workaround fix for iOS 15.1 has been released in the latest NPM version so closing this issue.
