Windows only issue. We really need smart standard functions to handle encoding (in and) out.

It would be better to force subprocess to use Unicode for command lines in Windows (or everywhere). The following might work, but I currently don't have any system to test it on:

cmd = [u'ffmpeg', u'-y', u'-i', path, u'-vn'] ...

(Does subprocess.list2cmdline([u"foo", u"bar"]) return a str or unicode object on Windows with Python 2?)

@grawity
This does not resolve the problem...
The list2cmdline returns an unicode object in Windows

Works fine with latest version.
