One of the archivists' best friends.
|
||
|
|
At least you don't have to go to those shady YouTube conversion sites anymore when you have a [[https://ytdl-org.github.io/youtube-dl/supportedsites.html][complete list of other video sites]] you can download from.

Here is an entryway into your newfound archiving habit.
|
||
|
|
Enjoy! :)

** Download the thumbnail and the audio of the video
|
||
|
|
|
||
|
|
Very simple.
|
||
|
|
Very useful as most of the thumbnails can go to high resolution and if you need them for some reason.
|
||
|
|
|
||
|
|
#+begin_src shell
|
||
|
|
youtube-dl --write-thumbnail --extract-audio https://www.youtube.com/watch?v=wy9VvdaLuSs
|
||
|
|
#+end_src
|
||
|
|
|
||
|
|
|
||
|
|
** Download an entire album
|
||
|
|
|
||
|
|
Though, you should look at the supported sites if it supports downloading an album out of the URL.
|
||
|
|
In this example, we have Bandcamp.
|
||
|
|
|
||
|
|
#+begin_src shell
|
||
|
|
youtube-dl --output '%(title)s.%(ext)s' --format bestaudio https://gametal.bandcamp.com/album/side-quests-vol-3
|
||
|
|
#+end_src
|
||
|
|
|
||
|
|
|
||
|
|
** Specific video download requirements
|
||
|
|
|
||
|
|
In this example, I want to download a video with a width of 1080px and the best video and audio at 320Kbit/s.
|
||
|
|
Oh, and the video should be in MP4 and the audio in Opus.
|
||
|
|
|
||
|
|
This is will only succeed if the format is available to download which you can do with =--list-format=.
|
||
|
|
|
||
|
|
#+begin_src shell
|
||
|
|
youtube-dl --format 'bestvideo[width=1080,ext=mp4]+bestaudio[abr=320K,ext=opus]' https://www.youtube.com/watch?v=wy9VvdaLuSs
|
||
|
|
#+end_src
