Hi,
since an upgrade of libmediainfo on my FreeBSD-server from 22.12 to 22.12_1 pymediainfo isn't working anymore:
Traceback (most recent call last):
File "/root/test.py", line 2, in <module>
pymediainfo.MediaInfo.parse("/mnt/temp/mediafile.mkv")
File "/usr/local/lib/python3.9/site-packages/pymediainfo/__init__.py", line 431, in parse
lib, handle, lib_version_str, lib_version = cls._get_library(library_file)
File "/usr/local/lib/python3.9/site-packages/pymediainfo/__init__.py", line 315, in _get_library
cls._define_library_prototypes(lib)
File "/usr/local/lib/python3.9/site-packages/pymediainfo/__init__.py", line 245, in _define_library_prototypes
lib.MediaInfo_Inform.restype = ctypes.c_wchar_p
File "/usr/local/lib/python3.9/ctypes/__init__.py", line 387, in __getattr__
func = self.__getitem__(name)
File "/usr/local/lib/python3.9/ctypes/__init__.py", line 392, in __getitem__
func = self._FuncPtr((name_or_ordinal, self))
AttributeError: Undefined symbol "MediaInfo_Inform"
Not really sure if this is the right place, but since this is a wrapper, I think it's better placed here and not with libmediainfo.
Downgrading libmediainfo to 22.12 works fine.
test.py:
import pymediainfo
pymediainfo.MediaInfo.parse("/mnt/temp/mediafile.mkv")

Hi @zwaehnn, I'm no FreeBSD expert. Does this 22.12_1 version correspond to this commit?
freebsd/freebsd-ports@23e0e7b
If so, could it be that they started packaging a wrong version of the library? Does the mediainfo CLI binary work with this library?
zwaehnn commented
Hi @sbraz, thanks for the reply.
I'm using the pkg-version of libmediainfo (https://www.freshports.org/multimedia/libmediainfo). The latest version (22.12_1) seems to correspond to this commit.
It could well be, that the issue has already been fixed, but the fix didn't arrive in the packaged version.
Since downgrading works for me, I think I'll just wait for the next update of libmediainfo and try it again.
But if anyone else has the same problem, hopefully there soon will be a google hit for the error message.
sbraz commented
Oh, I linked the commit for mediainfo, not libmediainfo. Yours is correct indeed.
I very much doubt the issue has been fixed. Can you please try the mediainfo binary?
Even if it works, you should report the issue upstream because the library doesn't seem to behave properly.

Hi,
mediainfo works with both both versions of libmediainfo:

Hi @sunpoet, since you're the author of the change to FreeBSD, do you have any idea why the change from CMake to autotools which you authored in freebsd/freebsd-ports@93d0a11 could affect pymediainfo which attempts to load libmediainfo.so?

Quick update: libmediainfo has been updated to 22.12_2.
Everything seems to be working again.
