Good evening
'''Thank you very much for sharing your great work!,''' I use ffmpeg to
optimize free lectures and it's great.
Question:
'''Could you please think about enabling ffmpeg to calculate a more
detailed DB histogram?
'''
As an example, ''volumedetect'' automatically selects the histogram ranges
and generates this result:
{{{
[Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_4db: 8
[Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_7db: 3369
[Parsed_volumedetect_0 @ 0000022cb9cf8c40] histogram_9db: 49398
}}}
I often would like to examine a dB range more closely, so it would be
brilliant if ''volumedetect'' could calculate more values.
These solutions come to my mind:
1. One can explicitly specify which dB ranges should be analyzed, e.g.
''"volumedetect:7;7.5;8dB"''
2. One can specify which dB range should be analyzed, e.g.
''"volumedetect:7-8dB"''
3. One can specify the number of calculated DB values, ''volumedetect''
then selects the ranges itself. e.g. ''"volumedetect:12"'' will calculate
12 histogram ranges.
I would prefer No. 1. because this is most flexible.
Thanks a lot for your review,
kind regards,
Thomas
