[SOLVED] Vapoursynth- Repo vslsmashsource bugged.

So I have an issue with trying to run Vapoursynth when using ffmpeg, l-smash, and libvslsmashsource.so
To clarify I am only using repo libraries here, but Compiling from source doesn't seem to resolve the issue unless i roll back glib.

basically i get this error:

Failed to load /usr/lib/vapoursynth/libvslsmashsource.so. Error given: /usr/lib/libgobject-2.0.so.0: undefined symbol: g_atomic_rc_box_release_full
Failed to load /usr/lib/vapoursynth/libvslsmashsource.so. Error given: /usr/lib/libgobject-2.0.so.0: undefined symbol: g_atomic_rc_box_release_full

The ouput of "readelf -sW /usr/lib/libgobject-2.0.so.0 | grep atomic":

    72:  0000000000000000     0 FUNC    GLOBAL DEFAULT  UND g_atomic_rc_box_release_full
   103: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND g_atomic_rc_box_acquire
   173: 0000000000000000     0 FUNC    GLOBAL DEFAULT  UND g_atomic_rc_box_alloc0

I've tracked the issue down to libavcodec. It seems something is broken between it and libgobject.
I've recompiled glib 2.73.3 and the issue resolves itself, but i'd rather not have to deal with the issues rolling back a core system library can cause.


SOLUTION:

Recompiled vslsmashsource from source using this git repo:

Re: [SOLVED] Vapoursynth- Repo vslsmashsource bugged.

What package are you using, exactly? `pacman -Qi glib2`

`lddtree /usr/lib/libgobject-2.0.so.0` may also be illuminating.

Re: [SOLVED] Vapoursynth- Repo vslsmashsource bugged.

'pacman -Q glib2' gives me :
glib2 2.74.5-1

output of 'lddtree /usr/lib/libgobject-2.0.so.0'

/usr/lib/libgobject-2.0.so.0 (interpreter => None)

You tried to recompile vaporsynth as well? You didn't receive linker errors?

I've recompiled glib 2.73.3

Arch has never shipped glib2 2.73.3, https://github.com/archlinux/svntogit-p … lib2/trunk

pacman -Qs 'ffmpeg|libav|vapour|glib'

Re: [SOLVED] Vapoursynth- Repo vslsmashsource bugged.

So it's pulling in the correct libglib-2.0 library, and that lib has the symbol in question. Sounds like it's something specific to Vapoursynth or the plugin you're talking about. If libgobject was actually messed up, a whole lot of things would crash.

It's going to be a lot of output, but set LD_DEBUG=files, I bet it's finding a different libglib-2.0 somewhere.

I did. None. It compile without errors. Got a bunch of deprication errors, but that was it.

Fair. but it was the newest version i could find that didn't cause the issue.

Not likely. This is actually a fresh arch install. It wasn't until after the reinstall this happened.

Re: [SOLVED] Vapoursynth- Repo vslsmashsource bugged.

So that wasn't the core issue. That was a leftover from something i tried before.

Turns out the git repo for libvslsmashsource I was using hadn't been updated to use Ffmpeg5.x. There is also something buggy with the repo version of libvslsmashsource. It wouldn't work at all, so i recompiled from source.

I used this Git repo:
