My local ffmpeg is ffmpeg-5, but this dependency pulls in ffmpeg-4 — can
I express "any version of ffmpeg"?

No, this would go against the goals of Guix: packages can't depend on properties of the environment they'll end up in (if any).

They must be self-contained, or use standard features like $PATH et al to find optional dependencies at run time, but these will have to be provided by the user/manifest/whatever.

Sorry,

T G-R

Sent on the go.  Excuse or enjoy my brevity.

To avoid profile collisions when the user installed a different version 
of ffmpeg (e.g. ffmpeg <at> 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:

https://0xacab.org/jvoisin/mat2/-/blob/master/libmat2/video.py#L139

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

Greetings,
Maxime.

This does not answer the question you asked, but if your intention is to 
pull in a newer version of ffmpeg, you can write ffmpeg-5 instead of 
ffmpeg-4.

Greetings,
Maxime.

What’s the right way to deal with this, then? I need ffmpeg at as
propagated-input, but I do not want to create a conflict with a manifest
that just defines "ffmpeg".

Best wishes,
Arne

In one my replies, I have proposed a method that avoids propagating ffmpeg:

Apologies for the top post.  I noticed this email and wanted to point you
to prior work, in case it proves useful:

Very cool — thank you! That should make it easier for me to follow the
tips.
