Initial setup

Enable the Linux development environment
Set up FlatHub
Install mpv from FlatHub
```
flatpak install flathub io.mpv.Mpv
```
Edit mpv.conf located in $HOME/.local/share/flatpak/app/io.mpv.Mpv/current/active/files/etc/mpv/mpv.conf
```
vo=gpu
gpu-api=opengl
opengl-es=auto
vd-lavc-dr=yes
gpu-context=wayland
```

Everyday use

Right-click on the Linux terminal in your apps and click on Shut down Linux
Start crosh by pressing Ctrl+Alt+T
Type in vmc start --enable-gpu --enable-big-gl termina
Wait for termina to start, the prompt will change from crosh> to (termina) chronos@localhost.
With crosh still open, start another regular linux terminal by clicking on the Terminal app
Type glxinfo -B (install meta-utils if it's not available) and verify that it says Accelerated: yes in the output
Use mpv with flatpak run io.mpv.Mpv <filename>

Note that you'll have to follow these steps every time you restart your computer or when Linux shuts down.
