Greenscreen visible in Chrome?

[GanWeaving]

[GanWeaving]

It works fine in my Firefox browser but not in Chrome.

[shiffman]

OS / browser version?

[GanWeaving]

Windows 7
Chrome 38
Firefox 31

[scottgarner]

Thanks, @Xeronimo74. I tested with Chrome 36 on Windows 7, but not 38. I'll grab it and give it a shot.

Any errors in the developer console?

[scottgarner]

Hmm. I tested Chrome (36), Chrome Beta (37) and Chrome Canary (38) in Windows 7 without any problems. Would you mind taking a look the demo on the homepage of http://seriouslyjs.org to see if that works?

[GanWeaving]

Hi, yes, seriouslyjs seems to work correctly. Still the same green screen problem with hello.p5js.org though ... The console gives me these errors:
18 : CS -> BG : FAILED closepopuptoplevel chrome-extension://hdokiejnpimakedhajhdlcegeplioahd/onloadwff.js:77

Thanks for testing, @Xeronimo74.

It looks like your LastPass extension is throwing some errors, but i don't see how that could affect the keying. Those font security errors are unusual, too, but also seem unrelated. Are you running any other exertions that might be causing problems?

Also, would you mind trying out this simplified chroma test: http://hello.p5js.org/test/chroma.html

Just hit play and see if playing with the sliders affects the key. Thanks!

Seeing a green screen with the Chrome browser.

[scottgarner]

Hi @Jdakotapowell. Can you provide your browser and OS version along with any errors in the console?

[Jdakotapowell]

Chrome - Windows Vista - as per console errors - can get bk to you on Sat -
on a deadline & sweating it out!

@Jdakotapowell Thanks for the feedback and take your time.

[nolanbjohnson]

Chrome (Version 36.0.1985.125 m) most up to date -- Windows 8. Don't see any console errors. Tried the chroma test above as well, but sliders have no effect.

[scottgarner]

Thanks for testing, @nolanbjohnson. Would you mind trying the demo at http://seriouslyjs.org to see if that works?

[nolanbjohnson]

the demo does work for me.

[scottgarner]

So strange! @brianchirls, mind if I rope you in here?

[nolanbjohnson]

Correction...I was not getting the full effect on the demo. The buttons applied a filter but did not completely replace the green screen. Just watched it on my mac and saw the difference. Sorry for the confusion.

[brianchirls]

This is a really tough one. Works fine on my Windows machine. And there are no obvious errors in the console.

So let's see if we can determine if it's Seriously.js in general or just the chroma key effect. @nolanbjohnson, @Xeronimo74 and @Jdakotapowell can you try out this page and let us know what you see?
http://brianchirls.github.io/Seriously.js/examples/animate/

There should be a canvas with an animated wipe effect going back and forth between some colored pencils and a toy robot with a purple pinwheel. Also, please check the console and let us know if anything shows up there.

And if you have the time, maybe you could list which browser extensions you have installed? We could see if there's anything you all have in common.

Thanks for your debugging help, everyone.

[GanWeaving]

Hi, I see that swipe effect. Plus a fine line of white dots at times (screenshot: http://i.imgur.com/3L8XYxT.jpg) ... No errors in the console.

As for the browser extensions: http://i.imgur.com/jwgju64.jpg , http://i.imgur.com/sJYl60h.jpg

[GanWeaving]

As for the Chroma test page, I'm seeing a green screen too. And the sliders don't seem to have an effect.

[brianchirls]

Ah those white dots are definitely not supposed to be there. Let me see if I can fix that...

I'm not too hopeful that the extensions will prove anything, but let's see what the others post and see if there's any overlap. thanks again.

[nolanbjohnson]

Ditto @Xeronimo74 on the swipe effect and the white dots. Don't see any overlap in extensions.

[brianchirls]

Okay, I think we can rule out the extensions. I suspect it has something to do with the way your GPU/drivers handle the branching in the shader. Can you guys try out this test for me? It's a modified version of the split effect that I hope will not have the white dots. If that's the case, then I have an idea of how I can fix the chroma effect too.

http://jsbin.com/zecoq/1

For comparison, here's the same thing using the original split effect, which should have white dots.
http://jsbin.com/hadej/1

Also, can you tell us what GPU hardware you're using?

Thanks,
B

[GanWeaving]

Yes, the second one has the dots while the first one does not.

I've got an integrated graphics card from Intel (this is my work PC) ...

[brianchirls]

Ah, excellent. I'll make an issue for this over at the Seriously.js repo and will see if I can fix Chroma key. May take me a day or two.

[scottgarner]

Thanks for jumping in here, Brian. I really appreciate it.

No problem. I want to see these issues solved for Seriously as well. It's looking like a long list of effects that may be affected.

We should probably do a call one of these days to go over a few different things that may affect your video piece, what could be fixed and what could be improved.

[brianchirls]

Here's an example using a modified chroma key effect. Does it work?

http://jsbin.com/dijog/1

[nolanbjohnson]

I don't see a green screen (it's a full white background) but no visuals either. Not sure if it's helpful, but there's a lot of aliasing around the edges.

[brianchirls]

Thanks. Do you hear the audio?

[brianchirls]

Updated to make video controls visible, so you can make sure it's playing.
http://jsbin.com/dijog/2

[nolanbjohnson]

Yep, audio is good.

[brianchirls]

@nolanbjohnson just to be thorough, did the modified split effect work for you? i.e. is there the line of white dots here? http://jsbin.com/hadej/1

[nolanbjohnson]

yes, I do see the dots.

[darkyen]

@nolanbjohnson can you tell me your output for chrome://gpu and then windows information for the gpu and driver via dxdiag ??

[nolanbjohnson]

Will do tomorrow morning @darkyen. Don't have my work laptop with me.

and windows:

[brianchirls]

@Xeronimo74 Can you tell me if the modified Chroma effect works?

http://jsbin.com/dijog/1

[brianchirls]

@nolanbjohnson: Thanks for posting that info. I talked to @darkyen and he wasn't able to replicate your problem. We're running out of options here...

The last thing I can think of is to try running the WebGL Conformance Tests. If you can paste the results here, I can try to see if it's picking up any quirks in your particular implementation. It will take a few minutes to run. When it's done, you can click "display text summary" and paste in the list of failures.

Chrome on my machine doesn't quite pass ALL of the tests, but maybe I can see if yours fails different ones from mine.

[brianchirls]

@nolanbjohnson I notice you're running Chrome with the --disable-gpu option. Did you set that up yourself? How come?

Maybe if you try running Chrome without that, you'll see different results. Or maybe it will crash. (That would count as "different," I think.)

[GanWeaving]

@brianchirls yes it works, white background

[brianchirls]

Great! Thanks, @Xeronimo74. So I'll fix this under the ticket over at my repo, which you are welcome to follow and comment on. I will also take a stab at refactoring other plugins to hopefully avoid the same problem.

[GanWeaving]

ok, cool!

[brianchirls]

@scottgarner The chroma effect is updated on the develop channel. Feel free to try it out. It should work the same for most people and solve the problem for @Xeronimo74.

https://github.com/brianchirls/Seriously.js/blob/develop/effects/seriously.chroma.js

[nolanbjohnson]

@brianchirls, when I run the WebGL test it goes fine for a bit and then everything starts failing.

This seems to be the recurring error msg:
FAIL Unable to fetch WebGL rendering context for Canvas
failed: context does not exist.

[nolanbjohnson]

Not sure why --disable-gpu option is there, @brianchirls. Though, when I try http://jsbin.com/dijog/1 it also works for me--white background.

[scottgarner]

Everything looks good so far on my end with the chroma effect from develop. Thanks, @brianchirls.
