A Rust implementation of the Moblin remote control assistant server. This server allows Moblin streamers to connect via WebSocket and provides remote control functionality.

• WebSocket server for Moblin remote control protocol
• Connection setup with challenge-response authentication (SHA256-based)
• Identification using password hashing with salt and challenge
• Ping/pong keep-alive mechanism
• Twitch chat ingestion and forwarding to Moblin
• YouTube live chat ingestion and forwarding to Moblin

cargo build --release

Start the server with a password:

cargo run -- --password my-secure-password

Or specify a custom port:

cargo run -- --password my-secure-password --port 2345

For release builds:

./target/release/moblin-assistant --password my-secure-password

The server uses env_logger for logging. You can control the log level using the RUST_LOG environment variable:

# Show only important events (info level)
RUST_LOG=info cargo run -- --password my-secure-password

# Show all debug information
RUST_LOG=debug cargo run -- --password my-secure-password

# Show everything including trace
RUST_LOG=trace cargo run -- --password my-secure-password

By default (without RUST_LOG set), the server runs silently. The logging levels used are:

• info: Major events like server startup, connections, authentication success, and Twitch channel joins
• debug: Detailed operational information like message exchanges and protocol details
• error: Error conditions like authentication failures and connection issues

The server implements the Moblin remote control protocol:

1. Hello: Server sends authentication challenge and salt
2. Identify: Client sends hashed password for authentication
3. Identified: Server confirms authentication status
4. Ping/Pong: Keep-alive mechanism
5. TwitchStart/YouTubeStart: Streamer requests external chat bridge setup
6. Chat Messages: Assistant forwards Twitch/YouTube messages to the streamer

1. Start the server:

   cargo run -- --password test123

2. Connect your Moblin app to the server using the IP address and password

3. Start Twitch and/or YouTube chat from the app and incoming messages are forwarded to Moblin
