> We do not support 4.4. I cannot reproduce on master. It does happen on
older ffmpeg in VLC e.g., sure./tag/latest
I download daily build ffmpeg-master-latest-win64-lgpl.zip from
https://github.com/BtbN/FFmpeg-Builds/releases。Unzip it on windows,enter
bin folder,run cmd,input :ffplay APE_48K_24bit_2CH_02_01.ape . After a
few seconds it appears big noise.
