 I'm wondering, is it a bug or intended, that ffmpeg does not tell you when
 it's renewing the font-cache (or whatever it does), when I define a new
 font-folder or add new fonts.
 ffmpeg stucks (seemlinly, due to not saying anything)
 "scans the fonts" as I assume.. and continues with my encode.

 Full debug output (note the "----" marked line, thats where it stucks):

 Reproduce it by defining a font folder in fonts config add some fonts and
 encode a video while using the ass filter.
