Live demos do not work.

[MariasStory]

Your live demos use to work for me, and it was real fun to play with it. Now, none of your live demos work for me. I am in the latest chromuim. Is there something I am doing wrong?

There is no real error in the console. For example, the last console output for the following demo: https://jeeliz.com/demos/faceFilter/demos/threejs/dog_face/ Console output: INFO in JeelizResizer: bestCameraResolution = Object DevTools failed to load SourceMap: Could not load content for https://jeeliz.com/demos/faceFilter/libs/tween/v16_3_5/Tween.min.js.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE main.js:23 INFO: JEEFACEFILTERAPI IS READY three.js:856 THREE.WebGLRenderer 97 JeelizThreeHelper.js:398 INFO in JeelizThreeHelper - update_camera(): Estimated vertical video FoV is 35 JeelizThreeHelper.js:417 INFO in JeelizThreeHelper.update_camera(): camera vertical estimated FoV is 35 deg three.js:618 THREE.WebGLProgram: gl.getProgramInfoLog()

Provide info requested here: https://github.com/jeeliz/jeelizFaceFilter#compatibility (screenshots of webglreport) and also provide the log of https://jeeliz.com/demos/WebGLCoreLogger/index.html

and please provide more info: does it ask for your camera access? Did you enable webcam access near the URL bar?

[MariasStory]

Hi @xavierjs, Sorry for the delay with answer. Indeed, the demo works on windows, android and iOS. The problem is seen on linux. I did use few systems with linux chromium and the demos did not work. FF also did not work. The camera is on and it seems that something is going on in the background. Maybe someone can confirm this problem on linux?

[xavierjs]

Hi @MariasStory

I need more info. I also have Linux and it works like a charm, both on FF and Chrome. The compatibility also depends on graphic hardware, GPU drivers, specific Linux version, ... Not only the browser / OS.

Please provide:

• the log (content of the textarea) of: https://jeeliz.com/demos/WebGLCoreLogger/index.html
• a screenshot of chrome://gpu (enter chrome://gpu on Chromium URL bar)
• a screenshot of https://webglreport.com/ and another of: https://webglreport.com/?v=2

Thank you

[MariasStory]

Thank you for this information.

Are you sure you are on Linux? The user agent written on webglreport screenshots ( striped in red ) seems to be Windows NT Win64 x64 (on Linux it should be X11; Linux x86_6 or something like that).

According to the log the computing part should work. Maybe it is a problem with the video or the camera driver (it happens to me a few years ago with a Sony Xperia mobile phone, the bug was fixed by some system update). Can you see the video of your camera here: https://webrtc.github.io/samples/src/content/getusermedia/gum/ (you need to click on the Open Camera red button ).

Which FaceFilter demos are you trying? The hosted ones? What about this one: https://jeeliz.com/demos/faceFilter/demos/threejs/cube2cv/

[MariasStory]

Yes, it is linux. Please ignore the user string. The last link with cube2cv works.

[xavierjs]

If cube2cv works, then the lib work. If it does not work on a specific demo, I need to know which demo is not working and I also need the log of the web console on this demo, otherwise I cannot figure out what goes wrong.

[chrsrns]

I'm currently observing this on my Linux machine. Should I comment the diagnosis above here or should I open a new issue?

[xavierjs]

Hi @LifeWatcher123

I have re-open the issue. Please provide some information so that I can figure out what happens:

0. On which demo does it happens?
1. the browser, the version of the browser, the operating system, the version of the operating system, the device model and the GPU if it is a desktop computer,
2. a screenshot of webglreport.com - WebGL1 (about your WebGL1 implementation),
3. a screenshot of webglreport.com - WebGL2 (about your WebGL2 implementation),
4. the log from the web console,
5. The logs of https://jeeliz.com/demos/WebGLCoreLogger/index.html
6. Does https://jeeliz.com/demos/faceFilter/demos/threejs/cube2cv/ work? Does it ask for camera access?

Sometimes another app using the camera can block the browser from getting the video stream.

Thanx, Xavier

I've tested it on the following filters:

• https://jeeliz.com/demos/faceFilter/demos/threejs/cube2cv/ (Cube is erratic)
• https://jeeliz.com/demos/faceFilter/demos/threejs/werewolf/
• https://jeeliz.com/demos/faceFilter/demos/threejs/angel_demon/
• https://jeeliz.com/demos/faceFilter/demos/faceReplacement/image

Machine Info:

• Using Vivaldi Browser (Stable 4.2.2406.52)
• Pop! OS 21.04
• No GPU (Using integrated graphics from an AMD APU)

Logs and WebGL Infos:

• https://gist.github.com/LifeWatcher123/cb59812d93dd3a237221615098fb220f
• 
• 
• The cube one does work, but the cube is erratic, going to seemingly random parts of the image at different sizes and orientation.

[chrsrns]

From what I've read on the issue, I think its important that I disclose that I am using Droidcam's virtual camera. The filters work on the iOS device, but not when used as a virtual camera.

[xavierjs]

Hi @LifeWatcher123

If the cube work works then it is not a WebGL / Camera issue.

Can you provide a screenshot of chrome://gpu (it should work on Vivaldi Browser since it is based on Chromium) ? Maybe there are some major GPU issues and fallbacks to software rendering. It can also comes from a specific GPU issue, which won't be astonishing since AMD drivers are not so great under Linux (I am also a Linux user and I always choose Nvidia/Intel for this reason).

What's about this demo: https://jeeliz.com/demos/faceFilter/demos/threejs/cube/ Does it work better than the previous cube one?

What is your current CPU model? I need to check the benchmark of the integrated GPU to see if it can just be a computing power issue.

Thanx, Xavier

[chrsrns]

If the cube work works then it is not a WebGL / Camera issue.

The cube was going on random spots on the video feed. But it does render, if that what determines whether WebGL works.

What's about this demo: https://jeeliz.com/demos/faceFilter/demos/threejs/cube/ Does it work better than the previous cube one?

No, unfortunately. It doesn't render anything above the video feed.

What is your current CPU model?

My CPU model is AMD A8-7650K Radeon R7 4C+6G

Here's the copy of the output from chrome://gpu: Unfortunately, I my screen capture browser extension can't capture this one. Here's a portion of the output for now while I find another tool for the screenshot (off topic: do you know a Linux screenshot utility that does a scrolling screenshot?):

[xavierjs]

Thanx for this information @LifeWatcher123 . Your GPU is good and hardware acceleration is fine. The problem should be elsewhere... Can you test:

• https://jeeliz.com/demos/tests/updated_FF/
• https://jeeliz.com/demos/tests/updated_FF_noAsyncReadpixels/

I hope at least one of the 2 will work... Thank you by advance

No! Both works splendidly!

[xavierjs]

Thanx @LifeWatcher123 The update on the master branch is coming in the next weeks (to celebrate the 2000 stars), with upgraded neural networks too (they are still training).

[chrsrns]

Neat! Can't wait.

Will the demos get updated automatically after that or are manual compilations necessary?

[xavierjs]

The static JavaScript demos will be upgraded (with the new FaceFilter and neural net). However, those running on a deprecated version of THREE.js (because using the legacy JSON format instead of GLTF) will still run on this old THREE.js.

The NPM package will be upgraded too so the react demo will be upgraded (new FaceFilter and new neural network)

[xavierjs]

I close the issue since it seems revolved, feel free to reopen it if the bug still occurs.
