FluxVision is a set of scripts for playing a YouTube playlist on loop on a Raspberry Pi. Anyone with access to a designated YouTube account can add a video to the playlist. This allows for simple administration of an easy to update, collaboratively-curated (if desired), looping video installation that doesn't require physical access to the player.

• Videos are downloaded once (not streamed)
• Automatically detects and downloads new videos when they are added to the YouTube playlist, usually available within one playthrough
• Automatically mutes at night (times can be edited)
• Support for a character LCD ticker that displays the title of the current video (requires Adafruit_Python_CharLCD)
• Support for an external skip button that advances to the next video
• Support for an external volume knob that adjusts video volume in real time (using a simple analog-to-digital converter with a linear potentiometer connected via GPIO pins)

• Recommended operating system is Raspbian Jessie, on which FluxVision was developed and stress tested. (Omxplayer was found to randomly hang between videos on Raspbian Wheezy.)

1. Install youtube-dl

sudo pip install --upgrade youtube_dl

2. Install omxplayer and libav-tools

sudo apt-get install omxplayer libav-tools

3. Download FluxVision files to your Raspberry Pi

git clone https://www.github.com/jasoneppink/FluxVision

4. Update "config.txt" with your playlist ID and other details.

cd FluxVision
nano config.txt

5. (optional) Uncomment lines in "startup.sh" if you are using a ticker, skip button, or volume knob

nano startup.sh

6. Open /etc/rc.local:

sudo nano /etc/rc.local

and add this line so FluxVision starts at boot:

sudo -u pi /home/pi/FluxVision/startup.sh

7. (optional) Clear disk space for downloaded videos. If you're running Raspbian, this command can remove up to 1GB of applications you probably don't use.

sudo apt-get remove wolfram-engine minecraft-pi python-minecraftpi sonic-pi oracle-java8-jdk pistore scratch nuscratch python3-pygame

8. Reboot! Videos play as soon as they're downloaded.

sudo reboot
