Can you please attach a logcat ? Note that Gecko does not support AR features

[sujay-digilens]

I have attached the logs in this comment.

If Gecko does not support AR features, how do I support WebXR (specifically, Immersive-AR mode of WebXR) on our platform?

There are 2 possibilities:

1. Implement WebXR AR modules in Gecko, or hire someone to do it, like Igalia
2. Wait for the Chromium backend which will allow WebXR AR at some point

Needless to say that the more partners supporting the development of Wolvic the faster features could be added/implemented

BTW in the logs you shared there is a crash in Gecko in a media codec, so very likely some media codec that is missing in your platform or that has a bug:

Thanks for the response @svillar .

1. Is there any documentation on how to implement the WebXR AR modules in Gecko?
2. Do you know how to fix the issue with media codec in the Gecko?

You have the specificacion https://github.com/immersive-web/webxr-ar-module. Then you have to implement it in Gecko. If you haven't touched a Web engine code previously then probably is not a task you could complete easily.

2. Do you know how to fix the issue with media codec in the Gecko?

Sorry I don't have enough data to check what's going on. Even with it I don't think we'd have time for that in the following weeks/months as we have higher priority tasks
