The patch produced with your command is attached. This is *not* the 
patch I want to provide.

Just believe me: I'm able to search the internet myself and luckily 
finally found 
https://stackoverflow.com/questions/5159185/create-a-git-patch-from-the-changes-in-the-current-working-directory.

BTW: I already spend hours to narrow this issue to libavformat. Just eat 
the provided patch either from the issue itself (cf. 
https://trac.ffmpeg.org/ticket/7827) or from this mailing list OR LET IT BE.

Cheers.
