@nicolocarpignoli @ThorstenBux we should transform the ES6 syntax used in some nft examples to the ES5 standard. i think it's a bit confusing. I have nothing in contrary in rispect to ES6 standard but there are good reasons to avoid to use:
Emscripten parser can not parse ES6 features
and for AR.js uglifyjs has also issues. So i suggest to change the code used in the most of the nft examples to the ES5 standard.

We could had an error handling at the end of the getUserMedia function:

navigator.mediaDevices.getUserMedia( hint ).then( function( stream ) {

  // video code

}).catch(function(err) { 

         console.log(err.name + ": " + err.message);

});

inside the nft examples,

This was merged in the https://github.com/artoolkitx/jsartoolkit5 master branch ! Probably i will close this PR.

@kalwalt Yes I think we can merge this one in the 'master' branch of your jsartoolkit5. The missing checklist points will be handled elsewhere :)

@nicolocarpignoli my master is already in sync with the latest form artoolkitx/jsartoolkit5 i can't merge this PR into my master because there are no other commits, so i will simply close.

Hi @kalwalt @nicolocarpignoli @ThorstenBux.

Hope you all are doing well. Great work guys. Congratulations!!!

I tested your examples.
I can run "main_threejs_wasm_worker.html" without any errors and I can see the sphere with my custom image.

Remaining 4 scripts which are:

1. "threejs_worker_gltf.html"
2. "main_threejs_worker.html"
3. "main.html"
4. "main_worker.html"

All gives common error which is: Uncaught SyntaxError: Unexpected end of input
at artoolkit.worker.js:1 @ /build/artoolkit.min.js: 13

and additionally, main.html also throws : main.js:108 Uncaught ReferenceError: ARCameraParam is not defined
at load (main.js:108)
at start (main.js:199)
at HTMLVideoElement. (main.html:52) main.js:108

Please help guys.
Thanks in advamce
