python - There is an errors embed album art with mutagen? -


the problem is, whenever embed picture mp3 , mp3 file increase less bytes picture is. i'll explain in code:

import os mutagen.mp3 import mp3 mutagen.id3 import id3, apic, error mutagen import file  audio = id3() open('111.mp3', 'rb') f:     rawfile = f.read()  dirpath, dirnames, filenames in os.walk('e:/exp/apic'):     fname in filenames:         path = os.path.join(dirpath, fname)          ap = apic(             encoding = 3,             mime = 'image/jpg',             type = 3,             desc = u'cover',             data = open(path, 'rb').read() )          sz_changed = os.stat('111.mp3').st_size         audio.add(ap)         audio.save('111.mp3')         sz_changed = os.stat('111.mp3').st_size - sz_changed         print u'lost bytes：%d' % (len(ap.data)-sz_changed)         open('111.mp3', 'wb') f:             f.write(rawfile) #reset

the code shows can't embed whole picture mp3 , neight mp3 player nor phone can read broken art problem is? although can embed pic when embed more larger pic.

now going show result of above code:

lost bytes：4174 lost bytes：5594 lost bytes：4924 lost bytes：4777 lost bytes：4938 lost bytes：4750 lost bytes：5558 lost bytes：4710 lost bytes：4924 lost bytes：5686 lost bytes：4936 lost bytes：4788 lost bytes：5319 lost bytes：5605 lost bytes：4790 lost bytes：4781 lost bytes：5692 lost bytes：5248

try changing:

mime = 'image/jpg' 'image/jpeg'

i had similar problem before , helped

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
