When using `--parse-metadate`, <meta_album_artist> does not properly overwrite the legacy metadata and <meta_artist> does not tag to the right field. #1958

Description

I use album_artist and artist metadata fields. I intend to label album_artist as uploader_id and artist as uploader.

For the field album_artist, instead of overwriting the legacy metadata (which yt-dlp defaults to artist) by the new metadata (which is uploader_id), yt-dlp just adds it as a separate tag entry. So I get artist; uploader_id instead of uploader_id.

For the field artist, instead of writing the metadata (uploader_id) to the artist field, yt-dlp writes it to the album_artist field.

Example of where I set uploader_id to artist

(Seen in the verbose log 1)

Set uploader_id to meta_artist

If whatever program you are using to view the metadata decided to merge the two fields, nothing I can do about it

Run ffmpeg -i "path/to/video.webm" and show the output

Conclusion

I noticed that the "badly displayed data" have the album artist and the artist field appear in the beginning in the log (with the title field being in first), and the "properly displayed one" have the "sypnosis" at the beginning with the "artist" and "album_artist" right after the "description" field.

Not sure how it affected the display but it did.

I also tried to use another program to display metadata (MP3TAG) and it also showed the data weirdly...

Suggestion: Maybe reorder how the metadata is written (when using ffmpeg -i)?

pukkandan commented 2 years ago

Maybe foobar issue? idk

Anyway, since the metadata is being written to the file and ffprobe can read it properly, it's not yt-dlp's issue
