Comment:
So, in commits
https://github.com/FFmpeg/FFmpeg/commit/7a7aa4f79e506eff8bddb971da2b7cf0dac7d009
and
https://github.com/FFmpeg/FFmpeg/commit/dc3325076597b41e0e05f201df2a8a84f588006d
you already solved my comments on twice assignment in first comment. So I
will add all other cases of "twice":
