The README says it can use ‘youtube-dl’ or ‘yt-dlp’ for vide downloads
and ‘ffmpeg‘ for some conversion, so maybe these could be added?

Also, propagation can lead to profile collisions which can be
complicated to resolve, so can this be made a regular input instead of
a propagated input?  Some wrap-program might be necessary.

Does it only support images, or also videos?  From the ‘ffmpeg’ and
‘youtube-dl’ dependency, I would assume the latter.  Also, when I'm
reading this description, it reminds me a lot of youtube-dl -- perhaps
the description could explain it supports more video sites, or less
video sites, or not only video but also images, or something along
these lines.

Why are tests disabled here?

Also, 'gallery-dl' (indirectly) uses openssl for the S in HTTPS,
so you may need to add SSL_CERT_DIR (or SSL_CERT_FILE, not sure) to
native-search-paths to make "guix shell --pure yt-dlp nss-certs" work.

Although there appears to be some disagreement in that area, see e.g.
some discussion in #53324, so maybe not.

Greetings,
Maxime.
