如何从 .mp3 中删除 "Writing library"？

Question

我试图在没有编码器信息的情况下对 .mp3 进行编码（“写入库”），但它失败了。我已经试过了：

ffmpeg -i test.wav -map_metadata -1 -map_chapters -1 test.mp3
ffmpeg -i test.wav -write_xing 0 -id3v2_version 0 test.mp3

和

ffmpeg -i test.wav -write_xing 0 -id3v2_version 0 -map_metadata -1 -map_chapters -1 test.mp3

但是“正在编写库：LAME3.100”仍然存在...

我需要做什么才能删除此元数据？ (写库)

Answer 1

只需在输出文件名之前添加 -metadata 'Writing library'='' 即可。

示例：

ffmpeg -i test.wav -metadata 'Writing library'='' test.mp3
