Doesn't start on Mint 19.3 about hypnotix

[dwvisser]

I am also on Linux Mint 19.3. I get a slightly different error on launch. I installed the v1.1 .deb, after first installing the imdbpy dependency by downloading a .deb from https://packages.ubuntu.com/focal/all/python3-imdbpy/download.

You can try python3-imdbpy from this place
http://lug.mtu.edu/ubuntu/pool/universe/i/imdbpy/python3-imdbpy_6.8-2_all.deb?
Maybe will help resolve your problem. That is advice from Clem, see by you self :-)

My problem is maybe related to my processor AMD Ryzen, who knows ???

[clefebvre]

What version of libmpv do you have?

[hahlic]

It say latest available version
libmvp1 0.27.2-1ubuntu1

[clefebvre]

Ok it looks like this would need an older version of python-mpv: jaseg/python-mpv#116.

[clefebvre]

We could maybe ship with two versions of python-mpv, check the version of libmpv and depending on that load one or another...

[clefebvre]

I'm not keen on targeting older releases for development but we could do that as a one-time fix.

I did the workaround of installing an older version of python-mpv (v0.3.9, v0.3.10, v0.4.0, even the last one 0.5.2 just for the lols) but unfortunately didn't work. The same error appears.
