Issue loading libp11-kit.so.0

[wabiloo]

Hi,

When using this library on Ubuntu, I get an error when doing MediaInfo.parse('https://pg-15-linear.perfectgame.tv/009000-389487-pg-321_4icz/file-3128k-01705.ts').

Failed to load library from libmediainfo.so.0 - /lib/x86_64-linux-gnu/libp11-kit.so.0: undefined symbol: ffi_type_pointer, version LIBFFI_BASE_7.0

Mediainfo was installed with sudo apt upgrade mediainfo and I can run it at the command line with that URL without a problem.

Any idea?

Hello, how did you install pymediainfo itself? Did you use Ubuntu's package? Do you have multiple libmediainfo.so.0 files on your system?

I (re-)installed in the following way (on Ubuntu 20):
sudo apt-get install --reinstall libffi7 libp11-kit0

There seems to be a single one on the system

ll /lib/x86_64-linux-gnu/ | grep libmedia
lrwxrwxrwx  1 root root       21 Mar 24  2020 libmediainfo.so.0 -> libmediainfo.so.0.0.0
-rw-r--r--  1 root root  7511464 Mar 24  2020 libmediainfo.so.0.0.0

Hello, how did you install pymediainfo itself?

I have a feeling you have another .so installed.
Please perform a full filesystem search for libmediainfo.so.0 or run strace -f -e openat <your_script.py> |& grep libmediainfo.so to see which one is used.
