David's Pi Looper Pro: Deployment Guide

This guide provides all the steps to take your generated Python script and turn it into a dedicated, reliable media player on a Raspberry Pi.

Your Details

Fill this out first. The commands below will update automatically.

Step 1: Preparing Your Raspberry Pi's SD Card

The best operating system (OS) for this project is Raspberry Pi OS Lite (32-bit). It has no desktop, which saves resources and makes your project more stable.

Installation Instructions

  1. Download and install the official Raspberry Pi Imager.
  2. Open the Imager, select your Pi model (e.g., Pi Zero 2 W), choose "Raspberry Pi OS Lite (32-bit)", and select your SD card.
  3. Crucial Step: Click the Cogwheel icon ⚙️ to open Advanced Options.
  4. In the Advanced Options, enable SSH, set your username/password, and configure your WiFi credentials.
  5. Click "Save", then click "Write" to flash the SD card.
Why pre-configure? This "headless" setup lets you control the Pi from your main computer over the network without ever needing to connect a monitor or keyboard to the Pi itself.

Step 2: Optimizing Videos for Pi Zero 2 W

Important: A Raspberry Pi Zero 2 W is powerful for its size, but it is not a desktop computer. It relies on a specific hardware video decoder. Videos that are not in a compatible format will stutter or fail to play.

For smooth playback, your videos should be converted to these specifications:

How to Convert Your Videos with HandBrake (Free)

  1. Download and install HandBrake for Windows or Mac.
  2. Open HandBrake and drag your source video file into it.
  3. Under "Preset", choose General → Fast 720p30. This will configure most settings for you.
  4. Go to the "Video" tab and ensure the "Video Encoder" is set to H.264.
  5. Choose a destination to save the new, optimized file.
  6. Click "Start Encode". Repeat for all your video files.

Step 3: Transferring Your Files to the Pi

After flashing, put the SD card in your Pi and power it on. Wait a minute for it to boot. Now you can transfer your generated script and your optimized media files.

Best Method for Large Files: SFTP Client

Since your video files are hundreds of megabytes, using a graphical SFTP client is highly recommended. It is more reliable than the command-line `scp` for large transfers and can often resume a transfer if the connection drops.

  1. Download a client like FileZilla or Cyberduck.
  2. Connect using the protocol SFTP.
  3. Enter your Pi's IP, username, and password (Port 22).
  4. Drag your script and media folder from your computer to the Pi's home directory (`/home/pi`).

Alternative: Using Command-Line SCP

1. Transfer the Python Script:

scp "C:\Path\To\Your\script.py" user@192.168.1.10:/home/pi/

2. Transfer a directory of media files:

scp -r "C:\Path\To\Your\media_folder" user@192.168.1.10:/home/pi/

Step 4: Creating an Auto-Restart Service

This final step turns your Pi into a robust appliance. The service will automatically start your script on boot and restart it if it ever crashes.

First, connect to your Pi via SSH:

ssh user@192.168.1.10

1. Install Required Software on the Pi

sudo apt update && sudo apt upgrade -y && sudo apt install vlc python3-pynput feh -y

2. Create the Service File

sudo nano /etc/systemd/system/interactive_controller.service

This opens a text editor. Copy the entire block below and paste it in.

[Unit] Description=David's Interactive Media Controller After=network.target [Service] ExecStart=/usr/bin/python3 /home/pi/interactive_controller.py WorkingDirectory=/home/pi StandardOutput=inherit StandardError=inherit Restart=always User=pi Environment=DISPLAY=:0 [Install] WantedBy=multi-user.target

Press Ctrl+X, then Y, then Enter to save and exit.

3. Enable and Start the Service

sudo systemctl enable interactive_controller.service

Start the service for the first time:

sudo systemctl start interactive_controller.service

4. Check the Status

sudo systemctl status interactive_controller.service

If it says "active (running)", you're all set! Press Q to exit the status view. Your project will now run automatically on every boot.
