Add support for macOS ARM

[Tohrusky]

In Mac OS arm, use pip to install, the libmediainfo.0.dylib is not found like. So I copy the lib in pypi pkg for macos x64, it work.

We found that in https://mediaarea.net/en/MediaInfo/Download/Mac_OS, libmediainfo.0.dylib is a universal lib for mac, so just add a package named like pymediainfo-6.0.1-py3-none-macosx_10_15_universal2.whl in PYPI, it can work

Hi, the wheel for v6.0.1 contains the x86_64+arm64 dylib, see my comment here: #24 (comment)

If you get https://files.pythonhosted.org/packages/a7/73/9f6602d6356bcf4c671f0d10999365cff6ebade197050f910d92f7501838/pymediainfo-6.0.1-py3-none-macosx_10_15_x86_64.whl, it should work. What version did your pip install command try to install? I need all that info in order to help you.

[Tohrusky]

just pip install pymediainfo

yep. I know the wheel for v6.0.1 contains the x86_64+arm64 dylib, but pip for arm mac will not install it.
To use pip install, a arm64 or universal2 tag like https://pypi.org/project/opencv-python/#files is needed ，or it will not install the Binary Wheel which contained the lib

[sbraz]

OK, so the wheel is fine but it lacks a universal2 tag, right? I assume I have to change

pymediainfo/setup.py

Line 29 in f97cd54

return 'py3', 'none', plat

I'll have to check this, the issue is that I don't have a MacOS system other than the AppVeyor CI so it makes it difficult to debug this.

In my repo, I force-name the platform. Hope it can help ya lol

And when python < 3.9, universal2 tag is not enabled, so add a extra pkg with arm64 tag is more easy

[sbraz]

Thanks, that's really helpful. In my case, I probably also need to force a platform name because I run code on a non-universal2 Python apparently.

Do you know if pip will find the universal2 wheel properly even if sysconfig.get_platform() returns macosx-10.9-x86_64 or macosx-arm64? Is that something you can test?

Also why do you disable this tag before Python 3.9?

When python >= 3.9, arm x86 and arm can find it. I have tested it in github action in the repo

Also why do you disable this tag before Python 3.9?

Python3.8 for arm seems not a official build.So the uni tag is enabled after 3.8

Hi, when launch my application with pymedia info I have this error:
OSError: Failed to load library from libmediainfo.0.dylib, libmediainfo.dylib - dlopen(libmediainfo.0.dylib, 0x0006): tried: 'libmediainfo.0.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibmediainfo.0.dylib' (no such file), '/usr/lib/libmediainfo.0.dylib' (no such file, not in dyld cache), 'libmediainfo.0.dylib' (no such file), '/usr/local/lib/libmediainfo.0.dylib' (no such file), '/usr/lib/libmediainfo.0.dylib' (no such file, not in dyld cache), dlopen(libmediainfo.dylib, 0x0006): tried: 'libmediainfo.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OSlibmediainfo.dylib' (no such file), '/usr/lib/libmediainfo.dylib' (no such file, not in dyld cache), 'libmediainfo.dylib' (no such file), '/usr/local/lib/libmediainfo.dylib' (no such file), '/usr/lib/libmediainfo.dylib' (no such file, not in dyld cache)

I have a problem with this library on my Mac arm m1/m2 mini.
Can I solve and fix this problem?

just copy a libmediainfo.dylib from here or the x86 mac pypi wheel to the package root directory.
its a universal2 lib.

not use pip, just download it, rename it to zip, unzip and find the lib.

to the package dir where you install it.
