Libavcodec conflicts

FFmpeg-users mailing list
So I wanted to install all the extra codecs for ffmpeg. I'm using mint 19. Right away apt tells me Libavcodec-extra57 conflicts with libavcodec57 and libavfilter-extra6 conflicts with libavfilter6. I was able to get it to install by using the force-depends flag but now apt -f install complains that vlc, ffmpeg and celluloid are broken and wants to uninstall them. I checked all of the above programs and they work fine but apts complaining is annoying.

Why are these packages in conflict? Is it recommended to install both side by side? This looks like a common problem from my internet searches. What is the recommended solution?

ffmpeg doesn't have the concept of plugins, so there's only a defined
set of codecs/filters/formats a compiled library can support.

If this packaging is anything like in Debian/Ubuntu, those packages are
either/or. Either you install the one with e.g. "fewer" codecs, or the
one with "more".

Moritz, Yes that is how it "should" work. Either set of packages either normal or extra should work, but that isn't what's happening. I installed the extras packages and apt tells me ffmpeg has "broken dependencies".

Well, originally, you wrote:

That means apt would have both after your install command, and cannot
do that. You may need to de-install libavcodec57 and install
libavcodec-extra57 in one step, or de-install the former first (also
breaking packages which depend on it), then install the latter.

I can't help you with that, I'm not very apt with apt (pun intended).
Please consult your friendly apt guide, or wait for other answers here.
;-)

Regards,
Moritz

You missed not only to find out what top-posting means and
to avoid it here but also that whatever your issue is it cannot
be solved within FFmpeg but only by your distribution.
(We do not offer libavfoo and libavfoo-extra, some distribution
has invented this years ago.)
