Automatically playing mp4 uploaded file

Support

Hi team,

Is it possible to put this forum page automatically playing that video whenever anyone just open the page?

Thanks in advance.

Instead of just having the video link handled by Discourse when it bakes the post, you can insert the video HTML element and add the autoplay attribute:

<video width="100%" height="100%" preload="metadata" controls="" autoplay>
      <source src="https://www.simscale.com/forum/uploads/default/original/3X/d/6/d6fab77fb56eeb98ef660d682f344dba4bbb66ce.mp4">
      <a href="https://www.simscale.com/forum/uploads/default/original/3X/d/6/d6fab77fb56eeb98ef660d682f344dba4bbb66ce.mp4">/forum/uploads/default/original/3X/d/6/d6fab77fb56eeb98ef660d682f344dba4bbb66ce.mp4</a>
</video>

Since the video has no sound, it will autoplay. If it had sound, you would have to add the muted attribute as well.

Hi @Canapin,

That’s really helpful, and I feel really appreciated for your answer.
BTW, is there any HTML attribute to insert loop for such video? Or you think by inserting this autoplay HTML string it will be automatically in loop?

Thanks once again,

You can add the loop attribute :slight_smile:

Nice @Canapin :slightly_smiling_face: I think it would be a great addition to Insert Video theme component as it has other option like nodownload too. It can probably appear on modal to each video upload. :thinking:
