Right-click this link and select "Play with MPV". MPV should popup and start playing the video. (Ctrl+Space also works)

• Linux: cp {/usr,~/.local}/share/applications/thann.play-with-mpv.desktop ~/.config/autostart
• MacOS: instructions
• Windows instructions

MPV is highly configurable, this is just how I like to use it.

To start in the corner, have no border, and stay on top: edit ~/.config/mpv/mpv.conf

ontop=yes
border=no
window-scale=0.4
geometry=100%:100%

In order to resize the window without borders, add keybinds: edit ~/.config/mpv/input.conf

` cycle border
ALT+UP add window-scale 0.05
ALT+DOWN add window-scale -0.05
