这是一个潜在的“陷阱”,我将在此处记录以防其他人绊倒它。我正在对可能是 .wav 或 .mov 格式的文件进行转换。测试看起来像这样:
if pic[0].audiodesc.path.lower().endswith('.wav'):
sound = AudioSegment.from_file(pic[0].audiodesc.path)
sound.export(mp3_filepath, format = 'mp3', bitrate = '64k')
elif pic[0].audiodesc.path.lower().endswith('.mov'):
sound = AudioSegment.from_file(pic[0].audiodesc.path, 'mov')
sound.export(mp3_filepath, format = 'mp3', bitrate = '64k')
在AudioSegment.from_file(pic[0].audiodesc.path)
,如果我指定 .., 'wav') 则编码失败:
