当文件名带有空格时，ffmpeg bash 脚本无法使用字幕

这是我当前的脚本

#!/bin/bash


while true
do
for f in *.mkv; 

do
/home5/user/ffmpeg_folder/./ffmpeg-git-20181101-64bit-static/ffmpeg \
 -i "$f" -c:v h264 -maxrate 12M -crf 16 -c:a copy -vf subtitles="$f" -pix_fmt yuv420p \
  "${f%.mkv}".mp4; 
  done
  sleep 15m
done

我不断收到此错误：

-vf subtitles="$f"如果里面没有的话一切都会正常。有没有什么办法解决这一问题？
