Package: ffmpeg
Version: 7:4.4.1-1+b1
Severity: wishlist
Hi,
ffmpeg is sometimes (often?) used to just convert video files and for
example generate previews. In that case, it's not useful/needed to
display anything (or echo any sound) so actually all output stuff could
be skipped, reducing dependencies.
It'd be nice (imho :) to have a way to install a headless ffmpeg
versions on those servers, and not have all those
fontconfig/libasound2/x11-common dependencies.
I'm unsure how hard it is on the packaging side though.
Regards,

It's a good point, but at least some of the big dependencies would be avoided.
On my LXC container with only nginx or so, installing ffmpeg adds:
0 upgraded, 150 newly installed, 0 to remove and 0 not upgraded.
Need to get 0 B/94.3 MB of archives.
After this operation, 317 MB of additional disk space will be used.
(and this is with --no-install-recommends)

Yeah unfortunately I was kind-of expecting this answer. I still think it's a
valid wish (especially with all those cloud environments) but I can understand
the maintenance problem.

some details.
With the following patch against Bullseye branch (disabling input and output
devices, and disabling some features) I'm down to:
apt install --no-install-recommends --with-source ffmpeg_4.3.3-0+deb11u1+nox1_amd64.changes ffmpeg

So about a third and no need for X11 stuff. I could have removed some more things but for now it's ok for me.

Hi,
And furthermore among the reverse dependencies of ffmpeg, some may claim only
the headless version. Any idea on this?
This "headless" approach is something nice for me and I was thinking of it
regarding a revision proposal of the graphviz packaging (see #998256).
Best,
Patrice

could you prepare a patch that makes this available as a package
build-time option, e.g. if DEB_BUILD_OPTIONS contains "headless"?
Thanks!
