I found a method in an answer of taglib's developer on stack overflow but it applies only to mp3 and I don't know how to convert it and save it as an image from the struct it returns. I found other methods always on Google but they are not working. 

You need to access the appropriate frame or atom in your tag.

Some aproximate code to get you started:

For ID3:

for ( auto it : v2Tag->frameList("APIC") ) {
    AttachedPictureFrame *apic = dynamic_cast<AttachedPictureFrame *>(it);
    if ( apic ) {
	// use apic->picture().data() of apic->picture().size() to create an image in your app framework
    }
}


For mp4:

CoverArtList coverArtList = tag->itemListMap()["covr"].toCoverArtList();
for ( auto it : coverArtList ) {
    CoverArt pic = static_cast<CoverArt >(it);
    // use pic->data().data() of pic.data().size() to create an image in your app framework
}

Hope this helps,
