[FFmpeg-user] Removing a metadata tag from a specfic stream

[Thibeau]

>Ugh.  Always coming back as "comment=other"?
Yea, but I'm not sure the value of tag is other and not just a value ffmpeg
doesn't  recognise and theirfor defaults to showing Other.

Same, I'm a real noob at ffmpeg. Trying to learn it but it's really hard
with the limited time I have to do it.

>That would be great.  Thanks.  I haven't found one that works for .flac
yet.
Disclaimer the commands are all for the file I uploaded if it's another
file don't forget to rename it in the commands.

> ffmpeg -i '29 My Girl.flac' -an -vcodec copy '29 My Girl.png'

This removes the art along with the associated metadata (comment=other)
> ffmpeg -i '29 My Girl.flac' -map 0 -map -0:v:0 -c copy '29 My
Girl-NoArt.flac'

Reattach the image:
ffmpeg -i 29\ My\ Girl-NoArt.flac -i 29\ My\ Girl.png -map 1 -map 0 -c copy
-disposition:0 attached_pic out.flac (refrence:

)

Hope this helps!
