Comment (by bookmoons):

 > How does the command line look that you used for testing?

 I used the scaling example in the wiki, with the image given there:
 https://trac.ffmpeg.org/wiki/Scaling

 {{{
 ffmpeg -i input.jpg -vf scale=320:240 output.png
 }}}

 A call trace showed that this hits the hScale8To15_c function (with
 -cpuflags 0). So I chose that one to start.
