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
