[Bug]: Song cover art endpoint returning MPEG-4 file #3859
Description
I confirm that:
- I have searched the existing open AND closed issues to see if an issue already exists for the bug I've encountered
- I'm using the latest version (your issue may have been fixed already)
Version
0.55.1 (beb768c)
Current Behavior
I noticed that some songs don't have a cover, even between different songs of the same album.
/rest/getCoverArt returns a MPEG-4 file instead of a jpeg.
Expected Behavior
It should return the album cover art as a jpeg
Steps To Reproduce
- clear cache
- request /rest/getCoverArt for affected song
- recieve application/octet-stream instead of image

After some investigation i noticed that the /rest/getCoverArt endpoint returns a file for those songs that:
- is much larger then a regular cover image (20 kb vs 900 kb)
- has no file ending but is of the type application/octet-stream
- starts with the line

This leads me to guess that navidrome for some reason returns a music file instead of the cover image here.
This occurs for several songs without any discernible pattern.
The songs are all .m4a files.
