Can Video (and similar) contents fallback into a QR code for PDF?

Description

I think the title explains the feature by itself. Here it is an example of what I want to achieve

::: {#fig-cern pdf-fallback=cernqr.png}

The video "CERN: The Journey of Discovery"

Or something similar. This way who prints the document has the option of to see the video, let's say, if it has a smartphone at hand.

If that QR code could be generated from the URL itself, that would be even more useful than a simple fallback,

::: {#fig-cern pdf-qr-fallback=true}

UPDATE: Maybe it is doable with conditional content: https://quarto.org/docs/authoring/conditional.html. I will try

UPDATE2: It was easier than I thought. This would make the trick,\usepage{qrcode} in the preamble, and

since LaTeX literal is ignored for HTML, it won't show up in the website. Whereas, for the PDF, we will have a nice QR code + Hyperlink

You could write a Lua filter to do that.
