"Cannot Find libmpv in the usual places"(OSX) #256

Closed gavspav closed 1 year ago

gavspav commented 1 year ago

I've seen other people with this issue but none of the solutions are working for me. I have an M1 Mac, I've installed MPV via homebrew and it works as a player. But 'import mpv' is throwing an error in my script.

I've even tried adding the path with the libmpv file to _dyld.py buy it doesn't seem to find it. I'm not sure what the next step is!

What did work for me is installing mpv using homebrew and then hardcoding the location of the libmpv file into the mpv.py file.

In my case this was: sofile = "/opt/homebrew/lib/libmpv.2.dylib"

I guess the better way to do it would've been to set my path variables somehow but I just couldn't figure it out!

I don't have a MacOS to try this out, but a google search suggests the DYLD_LIBRARY_PATH or the DYLD_FALLBACK_LIBRARY_PATH environment variable might be the right place to put the /opt/homebrew/lib path. From https://github.com/orgs/Homebrew/discussions/3424 it sounds like that is a known issue on homebrew on MacOS on ARM. From that discussion it also sounds like using a python installed through homebrew might fix this, since they build it with a patch for this behavior.

I'm closing this as an upstream issue, since there is not much we would do on our end to fix it -- I don't want to second guess python's find_library here, and that is really the place where this should be fixed.

In the meantime, I always intended mpv.py to be a single file you can just copy into your project and modify as needed. It's not considered good python packaging practice, but I think it's really not that bad, especially considering that python-mpv is very stable by now, and not security-sensitive.
