Summary of the bug:
How to reproduce:
{{{
% ffmpeg -v debug -i .\alman.m4a -af "ebur128=peak=true" ebur128test.mp4
}}}
This is a stereo AAC file with 44.1kHz sampling rate, going into ffmpeg
version N-106566-ge254af3154, built with gcc for mingw-w64 on April 11th,
2022.
With peak=true, we get (see below for fuller output):
{{{

unsupported.
