mutagen：如何在mp3，flac和mp4中检测和嵌入专辑封面

提问于

我希望能够检测音频文件是否嵌入了专辑封面，如果没有，则将专辑封面添加到该文件中 . 我正在使用诱变剂

1）检测专辑封面 . 是否有比这个伪代码更简单的方法：

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）我发现这是为了将专辑封面嵌入到mp3文件中：How do you embed album art into an MP3 using Python?

如何将专辑封面嵌入其他格式？

编辑：嵌入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()
python metadata albumart mutagen

    嵌入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()

    为了完整，检测图片

    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
    回复于
