[SOLVED] ffmpeg expecting wrong shared library

Wow, two topics in one day. Hopefully this one will be easier to solve, though.

I tried running ffmpeg on my desktop, but every time I do I get:

ffmpeg: error while loading shared libraries: libdav1d.so.5: cannot open shared object file: No such file or directory

It's really confusing, because according to the package website, ffmpeg should be expecting libdav1d.so.6, which is what dav1d provides, and which is what lives in /usr/lib. I've triple-checked the packages, and they are definitely up to date; ffmpeg is at 2:5.1.2-1, while dav1d is at 1.0.0-1.

I even tried installing ffmpeg-full from the AUR, which I expected would have compiled against the correct shared library, but it still expected libdav1d.so.5. I thought maybe there was another package that ffmpeg used which relied on dav1d, and maybe that was messing up? But as far as I can tell with pactree, ffmpeg is the only package that depends on dav1d.

Any help would be greatly appreciated. Thanks!

Check

type ffmpeg
ldd $(which ffmpeg) | grep dav1d

Perhaps you're not calling the ffmpeg binary installed by pacman.

Re: [SOLVED] ffmpeg expecting wrong shared library

...oh I'm stupid. Yeah, that was it. There was a version of ffmpeg in my home folder that was in my path, I had been using that when I was on Kubuntu, but it obviously messed up with the switch. The actual ffmpeg works fine.

Ever feel silly? Anyway, thank you for making me remember to check things.
