如何删除所有元数据但保留 ffmpeg 中的音频和字幕？

Question

I would like to removes all metadatas using ffmpeg, but keep every single audio and subtitle name. I have a code which works perfectly fine but it remove the audio and subtitle name (original subtitle name "English [eng] (subrip)" after i use the code "subrip").

bat file:

echo off
mkdir outputs
for %%a in ("*.mkv") do ffmpeg -i "%%a" -map_metadata -1 -map 0:a? -map 0:s? -map 0:v -c:v copy -c:a ac3 -c:s copy "outputs\%%~na.mkv"
pause

Answer 1

I answer my question because maybe I will help somebody.

-map_metadata:g -1 only strip global meatdatas so it will keep subtitles and audios.

echo off
mkdir outputs
for %%a in ("*.mkv") do ffmpeg -hide_banner -i "%%a" -map 0:v:0? -map 0:a? -map 0:s? -c copy -map_metadata:g -1 "outputs\%%~na.mkv"
pause
