Traffic/Webcam Viewer

Overview

This variant of vPlayer is designed to display live webcam or traffic images on a TFT screen. Instead of playing local videos from the SD card, the device periodically downloads and decodes JPEG images from specified URLs. It still relies on an SD card, but only for configuration rather than local video storage.

Key Features

Wi-Fi Connectivity Automatically connects to the network using credentials in /settings.txt.
Dynamic Image Retrieval Periodically fetches JPEG images from multiple URLs, allowing you to rotate through live webcams, traffic feeds, or any image-based stream.
Configurable Settings A simple file on the SD card (settings.txt) stores:
- Wi-Fi SSID and password
- Refresh interval (in milliseconds)
- List of up to 50 image URLs
Adaptive Scaling The JPEG decoder scales large images to fit available memory and optimize performance.
Potential for OTA/SD Updates Includes a placeholder function to check for firmware updates at boot (checkAndUpdateFirmware()), which you can expand for over-the-air or SD-based updates.

Getting Started

Prepare the SD Card Create a settings.txt file with the following (each entry on a new line):
```
YOUR_SSID
YOUR_PASSWORD
5000
https://example.com/image1.jpg
https://example.com/image2.jpg
```
- The first two lines are Wi-Fi credentials.
- The third line defines the refresh interval (in milliseconds).
- Each subsequent line lists a URL pointing to a JPEG image.

Note

While this variant of vPlayer doesn’t play videos, it’s perfect for low-bandwidth surveillance, traffic monitoring, or displaying live stills from your favorite webcams.
