I'm making my project in Python. I use a CSV module to extract the data from a CSV file. In my case, my CSVs are playlists created by Kreate, an android YouTube Music client. In those playlist CSV files, there's a colum that contains the video IDs for each item in the playlist. Part of my script extracts those, and formats YouTube video URLs out of them.
I use an app called media-downloader on Linux to do the actual batch downloading. It uses yt-dlp as its backend. I have my download options set to
-f bestaudio --extract-audio --audio-quality 0 --embed-thumbnail. My filename format is set to"%(uploader)s - %(title).200s.%(ext)s". The.200limits the title to 200 characters.Then for the thumbnail editing, I use my script to call ffmpeg to extract the thumbnail from the video, use
wand(Basically ImageMagick for Python) to crop the image to a square based on the image's height (You ever see those thumbnails with the solid colors on the side? That's what I'm removing.), then re-encode them using ffmpeg.For my setup, Media-downloader downloads files as OPUS, so I convert them to MP3 during the thumbnail portion of my script.
That was quite a wall of text, but I'll probably put my project on Codeberg when I'm done if you're interested in looking at the code.
