Describe the issue

When filling out the Language Field and then using Embed Metadata => Quick Embed, no id3 tag for the language is added or filled.

I checked if its there with vlc, windows properties and Mp3Tag.
I was working with a m4b file.

Steps to reproduce the issue

  1. Fill the Language Field in the Book Details.
  2. Navigate to Tools.
  3. Use Quick Embed.

Audiobookshelf version

v2.9.0

How are you running audiobookshelf?

Docker

The Audiobook File Management Tools in ABS also show no Language embed.

I was expecting to see it under 'additionalFields' or a Language Field. Or ideally as TLAN:

M4B files don't use ID3 tags. This is one of the difficulties with meta tags. We'll be switching back to using ffmpeg for embedding meta tags so might be further limited on the data we can embed. https://wiki.multimedia.cx/index.php?title=FFmpeg_Metadata
