This chnages the output from
./ffmpeg -i ~/tickets/1984/00186002.avi -vframes 100 -qscale 1 -an -bitexact file-1984-ref.avi
(i suspect its all yuv410p indeo videos not just this one)
I presume thats unintended
also the jobs number ideally, especially with bitexact should not change
the output
but maybe iam missing something
thx
