Hi Tobias,

peek, needs either ffmpeg or gnome shell to be present.

See here for the exact reference:

https://github.com/phw/peek/blob/2daba7cf114e01cff870afd20b96b212a0252054/src/application.vala#L67

How should I handle that in Guix?

Should I patch ffmpeg? What if a user wants to use gnome-shell instead of 
ffmpeg?

Is there a switch I can provide in Guile code?

all best,

jgart
