Skip files that already meet (or close enough) the requested normalization level #195

Closed milnak closed 1 year ago

Is your feature request related to a problem? Please describe. When running ffmpeg-normalize its possible that a file is already considered normalized (or close enough) - renormalizing the file with a lossy format (e.g. mp3) isn't ideal - for lossless formats like flac this is fine.

Describe the solution you'd like Is there a way to have ffmpeg-normalize skip files that are already considered normalized?

Describe alternatives you've considered I considered running the ffmpeg command myself and look at the resultant values and only call ffmpeg-normalize for remaining files, but it seems like this app could do a better job than I could.

Additional context None.

This is a duplicate of https://github.com/slhck/ffmpeg-normalize/issues/50.

It used to be possible but I haven't found time to implement it for the v1.0 rewrite.

Not planned for now, since I believe it's easier from a workflow perspective to just run the normalization again — if you choose to re-encode with a lossless codec, that won't hurt and ensure all your files are processed the same way.
