To avoid profile collisions when the user installed a different version 
of ffmpeg (e.g. ffmpeg@5) in their profile, could you modify the code to 
look at a /gnu/store/.../bin/ffmpeg instead?  Likewise for bubblewrap, 
gdk-pixbuf, poppler and librsvg, if feasible.

For ffmpeg, the following function needs to be modified:

(substitute* + search-input-file can be useful).

Greetings,
Maxime.
