ffmpeg - 我如何创建一个bash循环来将mkv文件转换为mp4

Question

您好我设计了一个命令，允许我将具有多音轨和字幕的mkv文件转换为保存所有视频轨道和字幕的mp4文件

现在我想制作一个bash循环来转换整个目录，但我做的bash没有工作

#!/bin/bash
for t in *.mkv  
do
name=$(basename -s .mkv "$t")
ffmpeg –I "$t" -map 0 -c:a aac -strict -2 -c:s mov_text "$name.mp4"
done

终端它把这个结果扔给我

你建议我改变我的命令 这是原始命令

ffmpeg -i INPUT.mkv -map 0 -c:a aac -strict -2 -c:s mov_text OUTPUT.mp4
