Introduction

Welcome to the TerminalSlideShow repository. This project is a lightweight, non-GUI slideshow that fetches new files from Google Drive, allowing you to update the slideshow remotely. This README provides instructions for setting up the project using Python, installing necessary requirements, configuring a Google Cloud project, and setting up auto-start functionality.

Setting up Google Cloud Project

Follow these steps to set up the Google Cloud project and obtain necessary credentials:

1. Create a new project on Google Cloud Console.
2. Navigate to "Service Accounts" on the left navbar and create a new service account with drive permissions.
3. Add a key in JSON format for the service account.
4. Use the email to grant permission to the target folder.

Prerequisites and Packages Installation

Ensure you have Python version 3.9.2 or higher installed.

Easy-Way-Install

• Execute: the initialize.sh inside the projectfolder using cd path/to/this_repo

Update

• To get newest repo version: python -m update.py --update

Manual-Way-Install:

Execute the following commands:

• install venv for python: sudo apt-get install python3-venv
• create a venv: python -m venv venv
• always use the venv: source path/to/venv/bin/activate
• Install requirements using: pip install -r requirements.txt

# Update package information
sudo apt update

# Upgrade installed packages
sudo apt upgrade

# Install required packages:
sudo apt install fbi vlc jq
sudo apt install libimage-exiftool-perl

#for MetaDataEdtor on MAC:
brew install exiftool
# Download the executable for windows: https://exiftool.org/

# Install recommended packages:
sudo apt install dos2unix

Project-Setup

To start you have to set some variables inside the config-file

Python Variables:

• TARGETDIR -> folder where the content will be saved
• USE_GDRIVE -> If you want to get the content from Google-Drive set it true
• GOOGLE_API_ACCESS -> Specifies the path to your service_account.json file
• DRIVE_DIR_ID -> The ID of the Google-Drive folder with your content

Bash Variables:

• ON_TIME and OFF_TIME -> Time when it should display (HH:MM) or (HH:MM:SS) (local time zone!)
• DISPLAYTIME -> Time for Duration for all images (in seconds)
• BLENDTIME -> Time for blending animation (in milliseconds)
• PYENV -> Path to the venv if you are using one. Else let it empty

MetaDataEditor

App

• Allows to add custom Tags to the file using a GUI
• STARTDATE -> Date when it will beginn displaying
• ENDDATE -> Date when it will stop displaying

!!!Under DEV:!!!

• DisplayTime -> Time how long the single image will be displayed (in seconds)

Allowed File Formats

• The script supports the following image formats: .jpg, .jpeg, .png, bmp, .gif(first frame).

• The script supports the following video formats: .mp4, .mkv, .avi, .ogg, mov, flv.

Allowed Formats for Google Drive

• The script supports the following date formats for filenames: day.month.year, 5.5.23, 05.05.2023, 15-06-2023, 20_07_2023

• You can also add a name before and after: FILENAME5.5.23stufff

• To set a time range use @: 5.5.23@08-12-23

Auto-start Configuration

To configure auto-start:

• Open the rc.local file: sudo nano /etc/rc.local
• Add sudo reset to an empty command line
• Go to the crontabs: crontab -e
• Add chmod to set the script as always executable and add the path to the script:

@reboot sudo sleep 8 && cd /path/to/project && sudo chmod +x path/to/script.sh && path/to/script.sh >/dev/null 2>/dev/null

# recommended
@reboot sudo sleep 8 && cd /path/to/project && dos2unix ./script.sh && sudo chmod +x ./script.sh && ./script.sh >/dev/null 2>/dev/null
