Comment (by cehoyos):
Does it work with an output codec different from jpg? (png)
Or even better, could you confirm that the following looks different for
you for frames 5 - 19?
Do you still see the "Operation not permitted" error?

To narrow down the reason for the problem, you could either test
"./configure && make", "./configure --disable-yasm && make", "./configure
--disable-asm && make" and "./configure --disable-optimizations && make"
or try with an older version of ffmpeg (assuming there is one that works)
and use git bisect to find the change introducing the problem.
