Fix for mpv-git

[bulvara]

Dear ozmartian,

may I change 4cf1458 back for my local build against mpv-git?

Yep, of course. That is what fixes the issue with mpv-git, you nailed it. But just edit mpv.pyx and delete mpv.c. It will be regenerated by python setuptools or manually via: $ python setup.py build_ext -i Cheers, Pete
