I'm trying to automatically play and loop a slideshow on a website using a file hosted on OneDrive. I first tried embedding the PowerPoint file directly:

<iframe src="source.pptx?wdAr=1.7770833333333333" width="476px" height="288px" frameborder="0">
</iframe>

But it didn't work.

Next, I exported the slideshow as a video (.mp4) and tried embedding it using both <iframe> and <video> tags, with autoplay and loop parameters:

Using iframe:

<div style="text-align:center">
    <iframe src="source.mp4?loop=1&autoplay=1" width="800px" height="550px" frameborder="0" allow="autoplay; loop">
    </iframe>
 </div>

Using video:

<div style="text-align:center">
    <video>
        <source src="source.mp4?loop=1&autoplay=1" allow="autoplay; loop" type="video/mp4">
    </video>
</div>

Nothing is autoplaying.

What am I missing? How can I make a OneDrive-hosted slideshow or video autoplay and loop on my website?

  • Are you sure the posted code recreates your actual problem? You can't have used src="source.mp4... if you knew the video is coming from OneDrive. You need to show (and use) a link that starts with https://onedrive.live.com/ and it needs to point to a real testable video. (2) Are these instructions useful to you as a starting point for embed in iframe? (3) Why not store video on your own website for <video> or store PDF for <iframe>? Commented Oct 17 at 15:23
