ffmpeg：复制/调整大小时如何保留输入元数据

如何解决ffmpeg：复制/调整大小时如何保留输入元数据

我希望输出文件具有与输入相同的元数据

我有两种情况：

带有图片

find . -name "*.jpg"|while read fname; do
  ffmpeg -y -i "$fname" -map_Metadata 0 -vf scale=1024:-1 ./compressed/"$fname"
done

带视频

find . -name "*.mp4"|while read fname; do
    ffmpeg -y  -i "$fname" -map_Metadata 0 -vf scale=1024:-2,setsar=1:1 -c:v libx264 -c:a copy ./compressed/"$fname"
done

在这两种情况下，元数据都丢失了（编辑设置当前日期的数据，我可以从原始文件中移动“编辑日期”）

参数 -map_Metadata 0 没有帮助

请告诉我，我应该修复什么？
