OpenBSD runs perfectly fine. Atom netbook, n270, 1GB of RAM, cwm+git dillo (plus DPI plugins), mpv+yt-dlp.

My ~/.config/mpv/config:

    #inicio

    ytdl-format=bestvideo[height<=?480][fps<=?30]+bestaudio/best

    vo=gl

    audio-pitch-correction=no

    quiet=yes

    pause=no

    vd-lavc-skiploopfilter=all

    demuxer-cache-wait=yes

    demuxer-max-bytes=4MiB

    #fin

My ~/yt-dlp.conf

    #inicio de fichero
    
    --format=bestvideo[height<=?480][fps<=?30]+bestaudio/best
    
    #fin de fichero

For the rest, I use streamlink from virtualenv (I do the same with yt-dlp) with a wrapper at $HOME/bin:

yt-dlp wrapper

    #!/bin/sh
 
    . $HOME/src/yt-dlp/bin/activate
    
    $HOME/src/yt-dlp/bin/yt-dlp "$@"

streamlink wrapper

    #!/bin/sh
    
   . $HOME/src/streamlink/bin/activate
   
    $HOME/src/streamlink/bin/yt-dlp "$@"

To install streamlink

       mkdir -p ~/src/streamlink

       cd ~/src/streamlink

       virtualenv .

       . bin/activate

       pip3 install -U streamlink

The same with yt-dlp:

      mkdir -p ~/src/yt-dlp

      cd ~/src/yt-dlp

       virtualenv .

      . bin/activate

      pip3 install -U yt-dlp

On the rest, I use mutt+msmtp+mbsync, slrn, sfeed, lynx/links, mocp, mupdf for PDF/CBZ/EPUB, nsxiv for images, tut for Mastodon and Emacs just for Telegram (I installed tdlib from OpenBSD packages and then I installed Telega from MELPA).

Overall it's a really fast machine. CWM+XTerm+Tmux it's my main environment. I have some SSH connection open to somewhere else at the 3rd tag (virtual desktop), and the 2nd one for Dillo.
