从命令行查找具有给定时间间隔的持续时间的所有视频文件

以下脚本将为您完成这项工作。假定视频在目录中（并非整个系统中）。

该脚本还假定您已avprobe安装，它是的一部分avconv。如果有语法，则应与ffprobe（的一部分ffmpeg）使用相同的语法。如果来自的输出ffprobe不同，则需要编辑脚本。

持续时间以秒为单位，但是需要-保存进行计算。

#!/bin/sh

# NOTE: Assumes you have avprobe installed and the full path
# to it is /usr/bin/avprobe - if not, edit.

# Where are the videos?
MASTER="/home/tigger/Videos"
# Duration min in seconds (1200 = 20min)
DUR_MIN="1200"
# Duration max in seconds (2400 = 40min)
DUR_MAX="2400"

# Get a list of files
LIST=`find "$MASTER" -type f`

# In case of a space in file names, split on return
IFS_ORIG=$IFS
IFS="
"

valid="\nList of videos with duration between $DUR_MIN and $DUR_MAX seconds"

# Loop over the file list and probe each file.
for v in $LIST
do
    printf "Checking ${v}\n"
    dur=`/usr/bin/avprobe -v error -show_format_entry duration "${v}"`
    if [ -n $dur ]
    then
        # Convert the float to int
        dur=${dur%.*}
        if [ $dur -ge $DUR_MIN -a $dur -le $DUR_MAX ]
        then
            valid="${valid}\n$v"
        fi
    fi
done

printf "${valid}\n"
exit
