我有一些Python代码，这些代码循环遍历音频文件，查找.FLAC文件，然后使用Python子命令运行ffmpeg。有用。音频效果很好，但是即使我在外壳中看到了元数据，它也没有将数据传输到MP3中的ID3标签，并且我使用的是上一篇文章中的示例。这是命令：
cmd = 'ffmpeg -y -i "' + src + '" -codec:a libmp3lame -q:a 0 -map_metadata 0 -id3v2_version 3 -write_id3v1 1 "' + dst + '"'
哪个可以解决：
ffmpeg -y -i "source.flac" -codec:a libmp3lame -q:a 0 -map_metadata 0 -id3v2_version 3 -write_id3v1 1 "destination.mp3"
这是日志转储：
