Question

我希望能够使用mutagen将相册封面添加到文件中，但是当我将其添加为文件时，它会返回：

File "D:\Download\pandora\renamingMETAEFF.pyw", line 71, in <module>
    meta['covr'] = image
File "C:\Users\AMD\AppData\Local\Programs\Python\Python35\lib\site-packages\mutagen\_file.py", line 67, in __setitem__
    self.tags[key] = value
File "C:\Users\AMD\AppData\Local\Programs\Python\Python35\lib\site-packages\mutagen\mp4\__init__.py", line 357, in __setitem__
    self._render(key, value)
File "C:\Users\AMD\AppData\Local\Programs\Python\Python35\lib\site-packages\mutagen\mp4\__init__.py", line 371, in _render
    return render_func(self, key, value)
File "C:\Users\AMD\AppData\Local\Programs\Python\Python35\lib\site-packages\mutagen\mp4\__init__.py", line 732, in __render_cover 
    b"data", struct.pack(">2I", imageformat, 0) + cover))

TypeError: can't concat bytes to str

相关的代码是：

from mutagen.mp4 import MP4

image = jpgname + '.jpg'
meta['\xa9nam'] = song
meta['\xa9ART'] = artist
meta['\xa9alb'] = album
meta = MP4(songPath)
meta['covr'] = image
meta.save()

其余的元数据完全正常，但图像部分完全破坏了整个代码。

Answer 1

来自mutagen docs：

MP4 meta'covr' - 封面图片，MP4Cover对象列表（标记为strs）。

MP4Cover imageformat - 图像格式（FORMAT_JPEG或FORMAT_PNG）

from mutagen.mp4 import MP4, MP4Cover

video = MP4("test.mp4")

video["\xa9nam"] = "Test1"
video["\xa9ART"] = "Test2"
video["\xa9alb"] = "Test3"

with open("cover.jpg", "rb") as f:
    video["covr"] = [
        MP4Cover(f.read(), imageformat=MP4Cover.FORMAT_JPEG)
    ]

video.save()

使用Mutagen在MP4文件中嵌入专辑封面
