#4724 closed enhancement (fixed)

support reporting on max variation in astats

Description

Summary of the bug:

I suggest adding a metadata value to the astats output to record the maximum variance in audio samples. The maximum variance would be the maximum absolute value of sample n minus sample n-1. This information could be useful to discover spikes, audio errors, edits, etc.

Imagined use:

ffprobe -f lavfi movie=movie.mov:s=a,astats=metadata=1 -show_entries frame_tags=lavfi.astats.1.Max_variance
