如何使用 yt-dlp（不同的开始和结束时间）bash 脚本从同一 URL 下载视频部分

Question

我正在尝试从同一个 YouTube 视频 URL 下载简短的部分，但有些视频由于已经下载而被跳过下载。

#!/bin/bash
missing=false
while IFS=, read -r url start_time_z end_time_z
do
    if [ "$url" == "" ]
    then
        echo "url is empty or no value set"
        missing=true
    elif [ "$start_time_z" == "" ]
    then
        echo "Start Time is empty or no value set for URL: $url"
        missing=true
    elif [ "$end_time_z" == "" ]
        then
                echo "End Time is empty or no value set for URL: $url"
                missing=true
        else
    
        echo "Downloading: $url | Start Time: $start_time_z | End Time: $end_time_zc
        echo "-------------------------------------------------------------------------------------------------------------"
        yt-dlp -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]" \
        --download-sections "*$start_time_z-$end_time_z" --restrict-filenames \
        -o "%(id)s_%(title)s_%(duration)s.%(ext)s" "$url" \
        --cookies /home/user1/yt-downloads/youtube_cookie.txt
                echo "-------------------------------------------------------------------------------------------------------------"
    fi
done < $1
if [ $missing ]
then
    echo "WARNING: Missing values in a CSV file. Please use the proper format. Operation failed."
    exit 1
else
    echo "CSV file read successfully."
fi

输入csv文件格式如下：

Answer 1

尝试使用开始和结束时间生成文件名： -o "%(id)s-%(section_start)s-%(section_end)s.%(ext)s"
