I tried using https://bookdown.org/yihui/rmarkdown/learnr-videos.html
but I get the error
! LaTeX Error: File `https://youtu.be/jg91ikK0OCI' not found.
Error: LaTeX failed to compile learn-isabelle.tex. See https://yihui.org/tinytex/r/#debugging for debugging tips. See learn-isabelle.log for more info.

Error: bookdown::render_book() failed to render the output format 'bookdown::pdf_book'.
Execution halted
I don't really care about pdf anyway. I just want HTML version of book. I heard learnr requires shiny backend https://github.com/rstudio/learnr/issues/168 . I don't even care about learnr. I just want to embed youtube videos in HTML output of bookdown.
I removed everything from _output.yaml. Previously this is what I had there
bookdown::gitbook:
css: style.css
config:
toc:
before: |
<li><a href="./">A Minimal Book Example</a></li>
after: |
<li><a href="https://github.com/rstudio/bookdown" target="blank">Published with bookdown</a></li>
edit: https://github.com/rstudio/bookdown-demo/edit/master/%s
download: ["pdf", "epub"]
bookdown::pdf_book:
includes:
in_header: preamble.tex
latex_engine: xelatex
citation_package: natbib
keep_tex: yes
bookdown::epub_book: default
bookdown::bs4_book: default
Removing it, prevented pdf from being generated and the error is gone but the youtube embedding still doesn't work.
The solution turned out to be quite obvious. Just embed the youtube video using iframe like so
<iframe width="560" height="315" src="https://www.youtube.com/embed/jg91ikK0OCI" title="YouTube video player" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" allowfullscreen></iframe>
