ID3v2 comment tag not added to MP3 file

[Georg]

Apologies if any formatting/method of this report should be incorrect, as I'm new to reporting bugs.

Summary of the bug:
When trying to add an ID3v1 and ID3v2 comment tag to an MP3 file, only the ID3v1 comment tag is written

How to reproduce:
I have tested it using the recent Windows builds

ffmpeg-N-101958-g39eafd0b2e-win64-gpl.zip
from ​https://github.com/BtbN/FFmpeg-Builds/releases

and

ffmpeg-4.4-essentials_build.zip
from ​https://www.gyan.dev/ffmpeg/builds/

I ran the following command in a Windows 10 shell

ffmpeg -i "input file.mp3" -map 0:a -codec:a copy -write_xing 0 -write_id3v1 1 -id3v2_version 3 -metadata track="1" -metadata title="Track Title" -metadata artist="Artist Name" -metadata album="Album Title" -metadata comment="Any Comments" "output file.mp3"

Using the command with -id3v2_version 4 instead of 3 creates the same result.

Possible cause:
I have found a post by someone much more knowledgeable than me on stackoverflow.com who wrote the reason could be that the ID3v2 comment tag is (quote) "wrongly written as a TXXX frame instead of COMM".

Thank you to everyone for your efforts, always greatly appreciated.
