Comment (by kurosu):
Would ne nice to have a (short) sample program or a FFmpeg command line,
ie anything needed to just measure the test case. I haven't looked but
isn't the reason for this slowness the use of atypical lengths. IIRC audio
codecs may have specifical short windows (max 2048 samples?).
