Hi,
I have a question about image extraction within a mp3 file. I could not find an answer in the FAQ and on this forum.
This is the output from the command "exiftool -ee myfile.mp3" :
Picture Mime Type : image/jpg
Picture Type : Front Cover
Picture Description : Magdalen Graal : Magdalen Graal
Picture : (Binary data 14486 bytes, use -b option to extract)
Picture Mime Type : image/png
Picture Type : Lyricist
Picture Description : http://www.jamendo.com
Picture : (Binary data 6889 bytes, use -b option to extract)
Picture Mime Type : image/png
Picture Type : Other
Picture Description : http://creativecommons.org/licenses/by-nc/3.0/
Picture : (Binary data 5145 bytes, use -b option to extract)
For example, I would like to extract only the "Front Cover" image. How could I do it ?
Thank you in advance
Regards
Samuel
Hi Samuel,
This isn't in the FAQ because it doesn't come up very often, but it is a bit tricky. Here is how to do this:
1) exiftool -a -G4 "-picture*" myfile.mp3
2) exiftool -COPYNUM:picture -b myfile.mp3 > cover.png
where COPYNUM is the instance number group name given in brackets from the output of the 1st command (or just -picture if there is no copy number).
Note that you should choose an extension for the output image based on the PictureMimeType with the same copy number.

Hi Phil,
I have tested your solution and it works well !
Thanks you for your quick reply.
I really appreciate your help.

Thank you so much for this image-extraction advice. I'm building a web library of audio books, and would like to extract the cover image from an .mp3 file. This does the job nicely.
Note that it is now possible to easily extract all available images from a set of files. To do this for all files in a directory:
exiftool -W %d%f_%t%-c.%s -b -preview:all DIR
This will extract multiple images from each file if they exist.
