我正在尝试解析 FFmpeg 输出文件的行。我尝试创建一个逐行读取行的变量，但每次我这样做时都会出现“[NULL @ 0x7fa9cb000000] 无法找到适合 '' 的输出格式：无效参数”
#!/bin/bash
origfolderdirectory=${PWD} # This is the original folder directory path.
origfoldername=${PWD##*/} # This is the original folder name.
# This creates a temp folder where all the temporary files will stay.
mkdir -p Temp
# This grabs a list of all .mp4 files and puts the output into files.txt
find . -name "*.mp4" >> ./Temp/files.txt
cd Temp
# This removes the dots from the start of every line in files.txt and outputs fileswithoutdot.txt
cat files.txt | sed 's/^..//' > fileswithoutdot.txt
# This adds the original folder name to the start of each line in fileswithoutdot.txt and outputs to prefixfiles.txt
cat fileswithoutdot.txt | sed -e "s#^#$origfolderdirectory#g" > prefixfiles.txt
# This adds ../Encoded. to the start of every line in prefixfiles.txt and outputs to prefixedfiles.txt
cat prefixfiles.txt | sed -e "s#$origfoldername#Encoded./$origfoldername./#" > prefixedfiles.txt
# Reads out prefixedfiles.txt for FFMPEG.
OUTPUT="$(cat prefixedfiles.txt)"
# Backs out of Temp folder
cd ../
# Copies folder structure of $origfoldername to ../Encoded.
find . -type d -exec mkdir -p -- ../Encoded./$origfoldername{} \;
# Removes temp folder from ../Encoded
rm -r ../Encoded./$origfoldername./Temp
# Do Encode
find . -name *.mp4 -exec ffmpeg -i {} -vcodec libx264 -acodec copy -threads 10 -crf 18 "${OUTPUT}" \;
