Mpv stopped working after system update

Support Software & Applications
1

I got a new system update today with 200+ packages to update
and after I installed everything I wanted to play a video using mpv and I saw it was not opening
I tried running it through the terminal and I get the following error:

mpv: error while loading shared libraries: libSvtAv1Enc.so.0: cannot open shared object file: No such file or directory

then I noticed the update installed the original MPV from the official repositories although I use mpv-full from AUR, I tried building removing the official mpv and building mpv-full again and I got a build error with the following errors:

/usr/bin/ld: warning: libSvtAv1Enc.so.0, needed by /usr/lib/gcc/x86_64-pc-linux-gnu/12.1.0/…/…/…/…/lib/libavcodec.so, not found (try using -rpath or -rpath-link)
/usr/bin/ld: warning: libsrt.so.1.4, needed by /usr/lib/gcc/x86_64-pc-linux-gnu/12.1.0/…/…/…/…/lib/libavformat.so, not found (try using -rpath or -rpath-link)

I tried looking where those so files come from and I found that libSvtAv1Enc comes from svt-av1 which I have installed from Official Repositories (extra)
and libsrt comes from srt which I also have installed from Official Repositories (extra)

running:

ls /usr/lib | grep -E libsrt|libSvt

return

libsrtp2.so
libsrtp2.so.1
libsrt.so
libsrt.so.1.5
libsrt.so.1.5.0
libSvtAv1Dec.so
libSvtAv1Dec.so.0
libSvtAv1Dec.so.0.8.7
libSvtAv1Enc.so
libSvtAv1Enc.so.1
libSvtAv1Enc.so.1.1.0
libSvtHevcEnc.so
libSvtHevcEnc.so.1
libSvtVp9Enc.so
libSvtVp9Enc.so.1

so I clearly have those libraries installed.

I tried reinstalling mpv, mpv-full, libSvt, libSrt and anything I could think of that might relate
but nothing fixed the problem.

how can I fix the problem, and if it’s not fixable by reinstalling or installing some extras
how can I find what package created the problem in the first place?

edit: using symbolic linking solved the problem
i.e.

sudo ln -s libsrt.so.1.5 libsrt.so.1.4
sudo ln -s libSvtAv1Enc.so libSvtAv1Enc.so.0

but it feels like a bandaid solution
is there a way to fix it without symbolic linking?

I don´t think so.

:smiley:

Have you rebooted since the update?

at first, I didn’t reboot cause I was lazy, and then when I saw the first error message I thought it was related to some libraries that were updated so I did reboot thinking it’ll solve the problem but it didn’t.

As it’s an AUR package, did you rebuild it after the update?

Build date of June 10th, indicates you didn’t.

TIL I had to rebuild the package
I rebuilt the package at then deleted the symbolic links and it seems like mpv still perfectly works.
thank you.

Is there a way to rebuild packages automatically, since getting major updates that upgrade all the system packages might break stuff again (apparently other software also broke .e.g RDKit), I would like to have a way that it’ll rebuild all the relevant packages again if possible, and not discover one by one which got broke

If it only needs rebuilding, then no.
If that gives you too much of a hassle on the long run, you should prefer repository packages, as those are rebuilt by the package maintainers when needed.
