Lightbox opens twice when Autoplay is used on BG video embed

[Dan13l (Daniel)]

Hey Guys,

there is an strange issue with the LIghtbox. I linked it to a video (vimeo link) and each time I click on the lightbox the video opens twice with a 1 sec lag which makes it very annoying to watch.

Issue appeared under
Chrome Version 45.0.2454.15 beta (64-bit)

OS:
MacBook Pro (Retina, 13-inch, Late 2012)
OS X Yosemite Version 10.10.3

Any ideas about that?

Best,
Daniel

Hi @Dan13l, thanks for the report. I checked and I was unable to reproduce the behavior under the latest stable branch of chrome (ver 44). Is the issue occurring from multiple computers you have access to ? Cheers, Dave

Hey @cyberdave,

yeah the issue occurs on every browser / device I tested but I figured out why.

We used the following Code to autoplay a Video as Background on our homepage and that causes the Lightbox to open twice.

    <video autoplay loop style="width:100%; height: auto; position:absolute; z-index: -1;">
  <source src="http://176.28.21.50/embed/embed.mp4" type="video/mp4" />
  <img src="image_url">
</video>

I now removed it and the Lightbox works fine again.

Any solution to this so I can still have a BG Video?
