ReplayGain Title correction is not evaluated? - pixel24 - 2023-09-03
Hi@all,
My entire music collection is in OGG Vorbis format. With OGG-Vorbis you can write a correction factor into the file header with VorbisGain so that the volume is uniform.
This is what I did in the whole collection. However, Jellyfin does not seem to evaluate this information.
Is it possible to configure this in JF?

I'm guessing, by looking at this table (https://en.wikipedia.org/wiki/Comparison_of_video_container_formats#Audio_coding_formats_support) that conversion is the problem.
You can click the link and read the footnote or read this: OGG containers are not supported and will trigger conversion. So the replay gain header you've put in is probably skipped because the media is being transcoded to a different format. I don't know as though that directive is read in when the media is transcoded since headers may not be fully parsed or executed when ffmpeg processes the file.
Is there a non-lossy way to apply the replay gain via scripting for these files pre-emptively? Or a conversion process to turn them into FLAC files while taking into account the replay gain? I'm just spitballing, as I've never dealt with OGG Vorbis and I'm not aware of the benefits or why one would choose that format over another.

Jellyfin 10.9 will have initial support for replay gain at which point clients can start adding support for it.

- MP3 did not support dynamic bitrate (I have -m 256 -M 512).
- A volume equalization in MP3 required a recoding.
And it is also not patent protected. On that today is still so I do not know. After ripping vorbisgain runs over the tracks and writes the correction value into the file header. All desktop players evaluate this information and play the tracks in uniform volume.

Great!
