FFmpeg添加了自己的元数据编码器: Lavf58.20.100
FFmpeg添加了自己的元数据编码器: Lavf58.20.100

我尝试将以下advice应用于flac文件：
for x in *.flac; do
ffmpeg -i "$x" -map 0:a -codec:a copy -map_metadata -1 clean_"$x";
done但是看起来，ffmpeg虽然删除了大部分metadata，但它也添加了自己的指纹。
为什么要添加这个标签？摆脱它的最好方法是什么？

根据https://ffmpeg-user.ffmpeg.narkive.com/EAjF25dp/encoder-lavf的说法，它是为了调试目的而显示libavformat的版本。

When I encode a video file it adds metadata that says
Encoder: Lavf52.94.0
I assume this means *L*ib*avf*ormat version 52.94.0. Why is this added? Is
it to brag that the video file was muxed with libavformat, or does it have
some productive reason?
It's not a "brag", it's primarily for debugging. If the file is
broken in some way, it's nice to know what version of libavformat
muxed it.
