> Any float audio stream will output different md5 values depending on
arch and instructions used. That's why the relevant FATE tests use
tiny_psrn, as it's not bit exact.
What I meant was: I tested several different aac samples with and without
{{{--disable-avx}}} and was unable to find a difference in the output of
{{{ffmpeg -i input.aac -f crc -}}}.
Do you have a sample that produces different output with and without avx?
