大功告成。

两个shell脚本也分享给大家。

function addsubtitle() {

if (( $# < 3 )); then

echo "USAGE packsubtitle video_filename subtitle_filename output_filename"

else

ffmpeg -i "$1" -f "${2##*.}" -i "$2" -c copy -metadata:s:s:0 languange=chi -metadata:s:s:0 title="CHS" -disposition:s:0 default "$3"

fi

}

function packsubtitle() {

if (( $# < 3 )); then

echo "USAGE packsubtitle video_filename subtitle_filename output_filename"

else

ffmpeg -i "$1" -f "${2##*.}" -i "$2" -c copy -map 0:v -map 0:a -map 1 -map 0:s -metadata:s:s:0 languange=chi -metadata:s:s:0 title="CHS" -disposition:s:0 default "$3"

fi

}
