Description

With some of my .flac files, value returned by drmeter filter can be negative or even "nan", using ffmpeg version 5.1.2 built on macos 12.6.3, running on M2 processor.

How to reproduce:

% ffmpeg -hide_banner -i sample.flac -af drmeter -f null - 2>&1 | grep -Eo 'Overall DR: .+'

As attachement seems limited to 2.5 Mo,I uploaded a sample.flac file (28Mo) with videolanfileuploader under ticket #10232.

I can confirm the problem still exists with version 6.0.

I also added another sample file here: ​https://www.dropbox.com/scl/fi/brzfbjyj3w74d99iul9na/sample2.flac?dl=0&rlkey=xwu0i85noyx0n58o08zajr058

This returns -74 as DR value.
