Thank you!

For the first question, I assume that you want to put all video downloaded into one big video in CLI. I guess you can do something like this with ffmpeg: ffmpeg -i "concat:input1|input2|input3|etc" -codec copy output.mkv If you want to work it out with yt-dlp you can try this:

yt-dlp "a link" Assuming you get mp4 format ls -1 *.mp4 > file_list.txt then ffmpeg -safe 0 -f concat -i list.txt -c copy output.mp4

Also, is downloading the mp4 significantly different in sound quality than bestaudio (which tends to output a webm rather than mp4)?

For your second question, I am not sure my self to be honest. I never actually look at it. That is why for my app this is the arg I use to get best video and also best audio: -f "bestvideo[ext=mp4]+bestaudio[ext=m4a]/best[ext=mp4]/best"

You can probably play a bit more with the format, if you feel like it.

Hope this help!

Yes, it work perfectly for youtube. In fact, it is the main way I download and consume music now days!

Thanks for the nice comment! I’m actually planning to maybe integrate the Picard metadata into my music downloader. It is still a plan though. I have no working prototype yet.

It seem to be really interesting! I will give it a try.

Thank you!!!

True! yt-dlp is the best.

Thank you!

I hope you will have a fun time with it!

If you have a water bottle and only drink half of it each time, you will also have infinite 💦
