问题
I'd like to be able to detect whether an audio file has embedded album art and, if not, add album art to that file. I'm using mutagen
1) Detecting album art. Is there a simpler method than this pseudo code:
from mutagen import File
audio = File('music.ext')
test each of audio.pictures, audio['covr'] and audio['APIC:']
if doesn't raise an exception and isn't None, we found album art
2) I found this for embedding album art into an mp3 file: How do you embed album art into an MP3 using Python?
How do I embed album art into other formats?
EDIT: embed mp4
audio = MP4(filename)
data = open(albumart, 'rb').read()
covr = []
if albumart.endswith('png'):
covr.append(MP4Cover(data, MP4Cover.FORMAT_PNG))
else:
covr.append(MP4Cover(data, MP4Cover.FORMAT_JPEG))
audio.tags['covr'] = covr
audio.save()
回答1:
Embed flac:
from mutagen.flac import File, Picture, FLAC
def add_flac_cover(filename, albumart):
audio = File(filename)
image = Picture()
image.type = 3
if albumart.endswith('png'):
mime = 'image/png'
else:
mime = 'image/jpeg'
image.desc = 'front cover'
with open(albumart, 'rb') as f: # better than open(albumart, 'rb').read() ?
image.data = f.read()
audio.add_picture(image)
audio.save()
For completeness, detect picture
def pict_test(audio):
try:
x = audio.pictures
if x:
return True
except Exception:
pass
if 'covr' in audio or 'APIC:' in audio:
return True
return False
