Python Mutagen:通过 url 添加封面照片/专辑艺术? [英] Python Mutagen: add cover photo/album art by url?

问题描述

使用mutagen，我可以添加普通的元标签，例如title、artist 和genre 但是当我尝试添加图像时通过网址，它不起作用.

Using mutagen, I am able to add normal metatags such as title, artist, and genre however when I try to add an image via a url, it doesn't work.

from mutagen.mp4 import MP4
from mutagen.mp4 import MP4Cover
from PIL import Image
import urllib2 as urllib
import io, sys, getopt

#url is defined elsewhere
audio = MP4(url)
#clear previous meta tags
audio.delete()

#get album picture data
cover ="http://cont-sv5-2.pandora.com/images/public/amz/5/2/9/7/095115137925_500W_488H.jpg"
fd = urllib.urlopen(cover)
image_file = io.BytesIO(fd.read())
ima = Image.open(image_file)
im = ima.tostring()

#processing
#I think it is here where it breaks
covr = []
if cover.endswith('png'):
    covr.append(MP4Cover(im,MP4Cover.FORMAT_PNG))
else:
    covr.append(MP4Cover(im,MP4Cover.FORMAT_JPEG))

#add cover
audio['covr'] = covr
#save everything
audio.save()

• 我知道它添加了除图像之外的所有标签，因为我可以用iTunes 正确，除专辑封面外都是空白
• 当我执行 ima.show() 时，它给了我图像
• I know it adds all tags except the image because I can open it with itunes correctly, all except the album art is blank
• when I do ima.show() it gives me the image

因此，我相信它可能会打破这条线:covr.append(MP4Cover(im,MP4Cover.FORMAT_JPEG))

because of this I believe that it probably breaks around this line: covr.append(MP4Cover(im,MP4Cover.FORMAT_JPEG))

有什么想法吗?还有其他方法可以从 url 获取图像吗?

any ideas? Is there another way to get the image from a url?

推荐答案

这对我有用:

fd = urllib.urlopen(cover)
# Drop the entire PIL part
covr = MP4Cover(fd.read(), getattr(
            MP4Cover,
            'FORMAT_PNG' if cover.endswith('png') else 'FORMAT_JPEG'
        ))
fd.close() # always a good thing to do

audio['covr'] = [covr] # make sure it's a list
audio.save()
