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:

  1. One can explicitly specify which dB ranges should be analyzed, e.g. "volumedetect:7;7.5;8dB"
  1. One can specify which dB range should be analyzed, e.g. "volumedetect:7-8dB"
  1. 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
