I may have mentioned it before, but I can watch YT content without
even opening a display server. I use various bits of software to
accomplish this.  And yes, this is a bit convoluted when there is
yt-dl and yt-dlp out there, but it's my way... for now.

I start by locating the video I want via RSS feeds or Idiotbox gopher
search. The pertinent string is the video ID right after the watch?v=.
Once I have that, I copy it (via tmux) and paste it into my
URL-generating script, which takes an Invidious domain (usually
yewtu.be) and populates three strings.

domain/latest_version?id=VIDEO_ID&itag=18
domain/latest_version?id=VIDEO_ID&itag=22
domain/latest_version?id=VIDEO_ID&itag=139

The itag corresponds to the 360p, 720p, and audio version of the
video, respectively. Out of respect to the site owners, I almost
always go for the 360p version as it's smaller and some videos don't
even go above 360p.

Then I just plug it into Lynx and after a few auto redirects, I get
the MP4 that I can play via Mplayer and framebuffer.
