python - 在 Python 3 中使用 Mutagen 将专辑封面嵌入到 mp3

Question

ID3 . 这是 Python 3 API，我不确定如何嵌入图像，到目前为止我在更改标签的地方有这个，

def addMetaData(url, title, artist, album, track):

    response = requests.get(url, stream=True)
    with open('img.jpg', 'wb') as out_file:
        shutil.copyfileobj(response.raw, out_file)
    del response

    audio = MP3(filename=title+".mp3", ID3 = EasyID3)
    audio['artist'] = artist
    audio['title'] = title
    audio['tracknumber'] = track
    audio['album'] = album

    audio.save()

Answer 1

我不认为可以使用 EasyID3 嵌入专辑封面，但可以使用 ID3。

您可以使用 ID3 嵌入专辑封面，如下所示:

from mutagen.id3 import ID3, APIC

audio = ID3('music_file.mp3')

with open('img.jpg', 'rb') as albumart:
    audio['APIC'] = APIC(
                      encoding=3,
                      mime='image/jpeg',
                      type=3, desc=u'Cover',
                      data=albumart.read()
                    )

audio.save()

如果性能不是您的主要关注点，您可以使用 EasyID3 保存文本元数据，然后使用 ID3 再次加载音乐文件以嵌入专辑封面。否则，您可以完全使用 ID3。

因此，第一种情况下的代码将是:

import requests
import shutil

# you can directly import EasyID3 and ID3
from mutagen.easyid3 import EasyID3
from mutagen.id3 import ID3, APIC

def addMetaData(url, title, artist, album, track):

    response = requests.get(url, stream=True)
    with open('img.jpg', 'wb') as out_file:
        shutil.copyfileobj(response.raw, out_file)
    del response

    audio = EasyID3('music_file.mp3')
    audio['artist'] = artist
    audio['title'] = title
    audio['tracknumber'] = track
    audio['album'] = album
    audio.save()

    audio = ID3('music_file.mp3')
    with open('img.jpg', 'rb') as albumart:
        audio['APIC'] = APIC(
                          encoding=3,
                          mime='image/jpeg',
                          type=3, desc=u'Cover',
                          data=albumart.read()
                        )            
    audio.save()

第二种情况:

import requests
import shutil

from mutagen.id3 import ID3, TPE1, TIT2, TRCK, TALB, APIC

def addMetaData(url, title, artist, album, track):

    response = requests.get(url, stream=True)
    with open('img.jpg', 'wb') as out_file:
        shutil.copyfileobj(response.raw, out_file)
    del response

    audio = ID3('music_file.mp3')
    audio['TPE1'] = TPE1(encoding=3, text=artist)
    audio['TIT2'] = TALB(encoding=3, text=title)
    audio['TRCK'] = TRCK(encoding=3, text=track)
    audio['TALB'] = TALB(encoding=3, text=album)

    with open('img.jpg', 'rb') as albumart:
        audio['APIC'] = APIC(
                          encoding=3,
                          mime='image/jpeg',
                          type=3, desc=u'Cover',
                          data=albumart.read()
                        )            
    audio.save()

注意:您也可以使用 urllib2 直接嵌入专辑封面，而无需先将其保存在磁盘上。示例:

import urllib2
from mutagen.id3 import ID3, APIC

audio = ID3('music_file.mp3')
albumart = urllib2.urlopen(url)

audio['APIC'] = APIC(
                  encoding=3,
                  mime='image/jpeg',
                  type=3,
                  desc=u'Cover',
                  data=albumart.read()
                )

albumart.close()
audio.save()
