Video Scrub flickering after Chrome update

[Andrea Contesini]

Hello, after Chrome last update, my code doesn't work anymore. Video is flickering on scroll. I activated controls on video to check the correct animation of GSAP and all seems to be good but video doesn't follow scroll correctly and needs seconds to align with the scroll position. Video is encoded correctly and since 5/6 day ago, it worked correctly an all devices and browsers. On Safari, for example, it works correctly.

It seems that the problem is related to Chrome on Mac.

Does anyone have a suggestion? Thanks so much.

 

Here's the code to play video on scrub.

//GESTISCO IL PLAY/PAUSE DEL VIDEO SECONDO LO SCROLL
      let video = document.querySelector('#thevideo');
      let sections = document.querySelectorAll('.gsap--section');
      /* Make sure the video is 'activated' on iOS */
      function once(el, event, fn, opts) {
        var onceFn = function (e) {
          el.removeEventListener(event, onceFn);
          fn.apply(this, arguments);
        };
        el.addEventListener(event, onceFn, opts);
        return onceFn;
      }
      video.play(); // must call .play() first, otherwise it won't trigger things to be scrubbable (weird)
      video.pause();
      
      var containerH = $(".gsap--outer").outerHeight();
      
      //TIMELINE
      const videoTl = gsap.timeline({
        scrollTrigger: {
          scroller: '.inner-site',
          pinType: 'fixed',
          anticipatePin: 1,
          trigger: ".gsap-pincontainer",
          start: "top top",
          end: "+=" + (100 * sections.length) + "%",
          pin: true,
          scrub: 2,
          // markers: true,
        }
      });
      videoTl.to( video, {
        currentTime: 14, 
      });
      videoTl.to(".gsap--outer", { 
        y: -(containerH - innerHeight), //100% - altezza del col-span
      }, "<");
      
    }

Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates the issue? 

 

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependancies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions. ✅

Hello, yes you are right sorry.

Here's the basic demo 

See the Pen qBvvMQK?editors=1010 by andreacontesini (@andreacontesini) on CodePen

Please use the lateral tabs view to see the correct view of sections.

If you check the code on Safari it works good but here on Chrome is flickering.

Thanks so much.

Here's a more simplified example with just the video

@Andrea Contesini is correct here, seems like a chrome regression. Unfortunately this isn't anything to do with the GSAP code Andrea, so we can't solve this for you.

I've opened a chrome issue here. Hopefully they get this fixed.

Hello Cassie, thanks so much for the support.

I hope Chrome team will check the issue and find a solution for us.

Have a nice day, i'll follow the ticket you opened.

 

Bye

Hello @Cassie Any news from Google Support?

I've tried to undestrand the ticket you opened but for me is very difficult. Which is the problem? Can Google support find a fast solution? 

Thanks so much.

Hey Andrea, yeah Chrome issue threads are confusing, you're basically just reading notes from members of the team to each other. They're not talking to us.

But it's been assigned (is being worked on)

 - edit - I checked and it looks like it's working for me in the latest version of chrome now.

[Andrea Contesini]

Hello @Cassie thanks for the update.

For me is not working, maybe I have to wait the next update, but reading the ticket the problem seems to be related to M3 Apple devices.

I hope they will fix asap.

 

Thanks, have a nice day.
