Request: Parse some missing metadata for WAV file

yas tam
Hello,

I posted about the bug that AIFF doesn't export ReplayGgain tag the other
day.
http://ffmpeg.org/pipermail/ffmpeg-user/2019-March/043713.html

It was solved with the help of Moritz. His patch for the following post.
http://ffmpeg.org/pipermail/ffmpeg-devel/2019-March/241033.html


I have one more request.
WAV files seem to export only part of metadata.
FFmpeg has not been able to export album_artist, composer, ReplayGain info,
etc of WAV files.
Could you modify it to support metadata that can not be exported from WAV
file?
source code: libavformat/wavdec.c
input method: wav_read_header(AVFormatContext *s)


The following is the actual input information of AIFF and WAV.
Innocence.aiff : aiff_input_fix_export_replaygain_version.txt
    * Input of AIFF by FFmpeg which applied the patch of ReplayGain of AIFF
Innocence.wav : wav_input_by_ffmpeg4.1.1.txt
    * Input of WAV by FFmpeg 4.1.1

I attach a screenshot showing the metadata of each file by Qoobar app. (

Innocence.aiff : Innocence.aiff_tag_info.png
Innocence.wav : Innocence.wav_tag_info.png

I uploaded music files that has used for confirmation below.
