mimu

Web app that makes the computer running the app play youtube videos in the background

To run

Run ./mimud.rb and ./frontend -e production, preferably within tmux/screen

TODO

• Implement deletion
• Add a way for the web frontend to know whether the backend is playing
• Emit signals when they should be (Trivial except for errorOccurred)
• Stop playing instantly when status changes to paused (currently plays current video to the end)

Specs

• When GETing /watch?v=:ytid, ask the user whether to add video :ytid to the end of the playlist.
• /playlist (redirect from /) is an HTML table representation of the playlist, along with buttons to
  • Delete any video from the playlist,
  • Play, and
  • Pause
• /playlist/:id removes :id from the playlist when DELETEd
• /play-pause, depending on method:
  • GET: "playing" if playing, "paused" if paused
  • POST: start playing if "play", pause if "pause"
• Playlist, kept in backend memory
  • ytid
  • Keep track of current array index
  • When /play-pause is set to "playing" and playlist has an unplayed video, start playing it (using youtube-dl and mplayer/vlc)
  • When the player stops, increment index and go to the previous step
• Communication between the front- and the backend
  • D-Bus (on the session bus) (NB! If you want to use the system bus, you must configure it yourself)
