Hello,

Dang Duong <khanhduongdv@gmail.com> skribis:

It seems that our vlc package lacks libass as an input:

  https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/video.scm#n8=
10

Could you try adding libass in the vlc package definition, then install
it, and see if it works?

If you=E2=80=99re not familiar with Guix packaging, see
<https://www.gnu.org/software/guix/manual/html_node/Defining-Packages.html>,
and do not hesitate to ask for guidance here or on #guix on IRC!

HTH,
Ludo=E2=80=99.
