Made some noise in linuxmint/hypnotix#254.

For the fix-deprecated-mpv-detach-destroy.patch, I believe when I want to PR to upstream I want to do a full sync with https://github.com/jaseg/python-mpv/blob/main/mpv.py but I am too lazy to know what is changed and when is the good time to do that and mint don't have libmpv.so.2 yet.
