FFMPEG 从 .mp3 输入向 .mp3 添加元数据？

如果我从一个 .mp3 文件开始，我该如何向其中添加元数据？我知道格式-metadata title="Some Title" -metadata artist="Someone"，但不确定如何将其应用于 .mp3 文件，尤其是当文件已经是 .mp3 时。

我在想更多这样的事情：ffmpeg -i input.mp3 -metadata artist="Someone" -f mp3 output.mp3

唯一的问题是，当我在 Kubuntu 18.04 上使用所有库编译的 ffmpeg 4 执行此操作时，出现以下错误消息：

输出流 #0:0 的自动编码器选择失败。mp3 格式（编解码器 mp3）的默认编码器可能已禁用。请手动选择编码器。
为流 0:0 选择编码器时出错

编辑：

当我尝试添加时也会发生这种情况-acodec libmp3lame，尽管错误似乎表明我没有 .mp3 编解码器

答案1

您的 ffmpeg 版本没有任何 MP3 编码器。但是，对于您的用例来说，这无关紧要。

使用

ffmpeg -i input.mp3 -c copy -metadata artist="Someone" output.mp3

输出必须是单独的文件。FFmpeg 无法更新输入本身。

我有数百个文件，我使用这个脚本。我希望对某些人有帮助。
