music embedded image not show

[zooter]

Hi all,

I have some music files, the main format is flac, a few mp3, and I expect jellyfin to use only the embedded ID3v2 data, all tags, including lyrics, embedded images, etc.
But right now only some of the songs are able to display images, and I'm not sure if the embedded data is used or if it's taken from the Internet.

I am checking the media info and jellyfin is able to read the media info but not able to display it, for example:

Can not show:
Image
Codec: MJPEG
AVC: No
Profile: Baseline
Resolution: 500x500
Bit depth: 8 bit
Color space: bt470bg
Pixel format: yuvj420p
Ref frames: 1

Can show:

Codec: MJPEG
AVC: No
Profile: Baseline
Resolution: 300x300

I hope you can help me, thanks~
