Description
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:
- One can explicitly specify which dB ranges should be analyzed, e.g. "volumedetect:7;7.5;8dB"
- One can specify which dB range should be analyzed, e.g. "volumedetect:7-8dB"
- 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
