Avoid video autoplay

[Nenuial]

Description

I'm including videos in my revealjs presentation like so :

![](path/to/video)

And I have the problem that the video autoplay in the presentation despite having set the YAML option auto-play-media: false under the revealjs key.

When I use the speaker notes I have the additional problem that the video plays in both speaker window and main window.

Any hints as to what I could try to avoid the videos starting automatically?

I opened an issue to track this at least for the video shortcode:

• Video shortcode "autoplay" should be at least an opt-in option #7905

Now the issue is that you did not provide a reproducible example we can use to reproduce the possible issue with the Reveal.js option auto-play-media.
Note that I cannot reproduce your issue with auto-play-media.

Thank you for your answer. I was so sure that it was just ignorance on my part regarding some setting for autoplay, that I never stop to consider it might be an issue somehow. Sorry about that, I would have made a reproducible example from the start otherwise: https://github.com/Nenuial/Video

On further analysis, it apparently has something to do with the template I use (quarto-revealjs-letterbox). Using that template, the videos always autostart (with shortcode or markdown syntax).

I'll investigate a bit more and might open an issue on the template repository.

There's some JavaScript that autoplays the video in the quarto-revealjs-letterbox. I'm sorry I haven't discovered that before.

The template makes this on purpose:

Thus the importance to always provide a reproducible example when asking a question.
Note that if no reproducible example is needed, it's likely when the search on the documentation website can show the answer.

You're right of course.
