BTW, if you want more informations you can check ticket #1962
(https://trac.videolan.org/vlc/ticket/1962).
Before Laurent Aimar's recent work (the backport you commited),
resampling was really broken. Now it's working great except for some
frequencies where bandlimited resampler module needs to be removed (or
a malloc() size needs to be increased).
