Screen Share Web App

This project is a Flask-based web application designed to provide a live screen-sharing feed with an interactive command console. Users can select a screen to share, view the feed, and enter commands to be executed on the server.

Features

• Live Screen Feed: View a real-time feed of a selected screen on the server.
• Screen Selection: Choose between available screens to stream live.
• Command Console: Execute shell commands directly through the web page.
• Responsive Interface: A dark-themed, responsive web interface with a left panel for screen feed and a right panel for the command console.
• Kill session with /kill page: Easy exit without popup.

Libraries Used

Flask

Flask is used as the main framework for serving web pages and handling requests. The application uses Flask's routing, templates, and JSON responses.

• Flask: The core web framework.
• Flask-Bootstrap: For Bootstrap integration, providing a consistent layout and responsive design.

PIL (Python Imaging Library)

PIL is used to capture and manipulate screen images, converting them into JPEG format for efficient web streaming.

• Pillow: The modern version of PIL, used here to handle image capture and conversion.

mss

mss is a cross-platform library for capturing screen data. It allows for efficient screen grabbing, essential for creating the real-time feed.

Subprocess

The subprocess module is used to run shell commands from the web console and capture their output.

Other Utilities

• Threading: Manages continuous screen capture without blocking other processes.
• Base64: Encodes the JPEG screen feed as a Base64 string to be served as an image source in the web interface.
• Signal: Used to gracefully shut down the server on demand.

Web Page Settings and Recommendations

Layout

The web interface is divided into two main sections:

1. Left Panel (Screen Feed): Displays the live screen feed with a dropdown and a button to select the screen. The selected screen updates dynamically every 0.2 seconds (5 FPS).
2. Right Panel (Command Console): Contains a console area to view command outputs and a text input for entering commands. The background is black, with white text for improved visibility and readability.

Styles and Interactivity

• Dark Theme: The page has a dark theme for easier viewing in various environments.
• Responsive Design: Adapts to different screen sizes, with CSS ensuring the layout remains flexible.
• Clear Command: Users can type clear or cls in the console to reset the command output.

Recommendations

• Security: Update the app.secret_key with a secure, unique key to protect session data.
• Usage in a Controlled Environment: This application should only be used in a secure, local network. Running shell commands from a web interface poses significant security risks if exposed to untrusted networks.
• Screen Refresh Rate: The screen capture FPS is set to 60 by default to balance performance and update speed. Adjust if needed for your system's capabilities.

Running the App
