For now mpv is not packaged, meaning you need to install the mpv library when using the desktop application:

• Windows: download mpv-dev, unpack, put corresponding mpv-1.dll to C:\Windows\system32
• macOS: brew install mpv
• Linux: apt-get install libmpv1 libavformat-dev

npm install

Browser:

npm run serve

Electron:

npm run electron:serve

Browser:

npm run build

Electron:

npm run electron:build
