  handleMetadata: true,
  metadataCallback: (metadata) => {
    if (metadata.type === 'tool_call') {
      console.log('Tool call received:', metadata.content);
      // Here you would handle the tool call and send back results

});

Advanced Usage

Steganography with LLM-Generated Algorithm

Use an LLM to dynamically generate steganography algorithms:

import { processAIStreamToStegRtp } from 't140llm';
import OpenAI from 'openai';
import { readFileSync } from 'fs';

// Initialize OpenAI for algorithm generation
const openai = new OpenAI({
  apiKey: process.env.OPENAI_API_KEY,
});

// Load some cover media (in this example, image files)
const coverMedia = [
  readFileSync('./cover-image-1.jpg'),
  readFileSync('./cover-image-2.jpg'),
  readFileSync('./cover-image-3.jpg'),
];

// Generate a steganography algorithm
const prompt = `Create a steganography algorithm in JavaScript that:
1. Takes a data Buffer and cover media Buffer
2. Hides the data within the cover media
3. Returns the modified cover with hidden data
4. Includes a corresponding decode function
5. Uses pure JavaScript with no external dependencies`;

// Get the algorithm from OpenAI
const response = await openai.chat.completions.create({
  model: "gpt-4",
  messages: [{ role: "user", content: prompt }],
  temperature: 0.5,
});

const algorithm = response.choices[0].message.content;

// Create a streaming request from Claude or any other LLM
const textStream = await claude.messages.create({
  model: 'claude-3-sonnet-20240229',
  max_tokens: 1000,
  stream: true,
  messages: [{ role: 'user', content: 'Tell me about steganography techniques' }],
});

// Process the stream with the LLM-generated steganography algorithm
const transport = processAIStreamToStegRtp(textStream, '192.168.1.100', 5004, {
  steganography: {
    enabled: true,
    encodeMode: 'llm',
    algorithm, // Use the LLM-generated algorithm
    coverMedia,
    seed: 'unique-random-seed-123'
  },
  enableFec: true, // Enable Forward Error Correction for reliability
});

Custom Steganography Transport

Create a custom steganography transport with advanced features:

import { StegTransport, createT140RtpTransport } from 't140llm';
import OpenAI from 'openai';

// Create a custom steganography transport that extends the base StegTransport
class EnhancedStegTransport extends StegTransport {
  constructor(innerTransport, config) {
    super(innerTransport, config);
    this.stats = {
      packetsEncoded: 0,
      bytesHidden: 0,
      avgBitChanges: 0
    };
  }
  
  // Override the encode method to add statistics
  encode(data, cover) {
    console.log(`Encoding ${data.length} bytes into ${cover.length} bytes cover`);
    this.stats.packetsEncoded++;
    this.stats.bytesHidden += data.length;
    
    // Call the parent encode method
    const encoded = super.encode(data, cover);
    
    // Calculate bit changes for statistics
    const changes = this.countBitChanges(cover, encoded);
    this.stats.avgBitChanges = 
      (this.stats.avgBitChanges * (this.stats.packetsEncoded - 1) + changes) / 
      this.stats.packetsEncoded;
    
    return encoded;
  }
  
  // Helper to count how many bits were changed during encoding
  countBitChanges(original, modified) {
    let count = 0;
    const len = Math.min(original.length, modified.length);
    
    for (let i = 0; i < len; i++) {
      const xor = original[i] ^ modified[i];
      for (let bit = 0; bit < 8; bit++) {
        if ((xor >> bit) & 1) count++;
      }
    }
    
    return count;
  }
  
  // Add a method to get statistics
  getStats() {
    return { ...this.stats };
  }
}

// Generate some cover media
function generateCoverMedia(count = 5, size = 10240) {
  const media = [];
  for (let i = 0; i < count; i++) {
    const buffer = Buffer.alloc(size);
    for (let j = 0; j < buffer.length; j++) {
      buffer[j] = Math.floor(Math.random() * 256);
    }
    media.push(buffer);
  }
  return media;
}

// Create a custom pattern-based algorithm
const customAlgorithm = `
function encode(data, cover) {
  // Ensure cover is large enough
  if (cover.length < data.length * 10) {
    throw new Error('Cover media too small for data payload');
  }
  
  // Create a copy of the cover
  const result = Buffer.from(cover);
  
  // Store data length in first 4 bytes
  for (let i = 0; i < 4; i++) {
    result[i] = (data.length >> (i * 8)) & 0xFF;
  }
  
  // Embed data using pattern-based approach
  const patternSize = 4; // 4 bytes per bit
  const patternCount = Math.min(data.length * 8, Math.floor((cover.length - 32) / patternSize));
  
  for (let i = 0; i < patternCount; i++) {
    const byteIndex = Math.floor(i / 8);
    const bitIndex = i % 8;
    const bit = (data[byteIndex] >> bitIndex) & 1;
    
    // Position in cover
    const coverPos = 32 + (i * patternSize);
    
    // Apply pattern change for bit
    if (bit === 1) {
      // For '1' bit, make gradient ascending
      for (let j = 0; j < patternSize - 1; j++) {
        if (result[coverPos + j] >= result[coverPos + j + 1]) {
          result[coverPos + j + 1] = result[coverPos + j] + 1;
        }
      }
    } else {
      // For '0' bit, make gradient descending
      for (let j = 0; j < patternSize - 1; j++) {
        if (result[coverPos + j] <= result[coverPos + j + 1]) {
          result[coverPos + j + 1] = Math.max(0, result[coverPos + j] - 1);
        }
      }
    }
  }
  
  return result;
}

function decode(stegData) {
  // Extract data length from first 4 bytes
  let dataLength = 0;
  for (let i = 0; i < 4; i++) {
    dataLength |= stegData[i] << (i * 8);
  }
  
  // Validate data length
  if (dataLength <= 0 || dataLength > (stegData.length - 32) / 32) {
    throw new Error('Invalid data length in steganographic content');
  }
  
  // Create result buffer
  const result = Buffer.alloc(dataLength);
  
  // Extract data using pattern detection
  const patternSize = 4;
  const patternCount = Math.min(dataLength * 8, Math.floor((stegData.length - 32) / patternSize));
  
  for (let i = 0; i < patternCount; i++) {
    const byteIndex = Math.floor(i / 8);
    const bitIndex = i % 8;
    
    // Position in stego data
    const stegPos = 32 + (i * patternSize);
    
    // Detect pattern
    let ascending = true;
    for (let j = 0; j < patternSize - 1; j++) {
      if (stegData[stegPos + j] >= stegData[stegPos + j + 1]) {
        ascending = false;
        break;
      }
    }
    
    // If pattern is ascending, the bit is 1
    if (ascending) {
      result[byteIndex] |= (1 << bitIndex);
    }
  }
  
  return result;
}`;

// Create a simple logging inner transport
const loggingTransport = {
  send: (data, callback) => {
    console.log(`Sending ${data.length} bytes of data`);
    if (callback) callback();
  },
  close: () => {
    console.log('Transport closed');
  }
};

// Create an enhanced steganography transport
const coverMedia = generateCoverMedia();
const stegTransport = new EnhancedStegTransport(loggingTransport, {
  enabled: true,
  encodeMode: 'fixed',
  algorithm: customAlgorithm,
  coverMedia,
  seed: 'custom-steg-example'
});

// Create an RTP transport using our custom steg transport
const rtpTransport = createT140RtpTransport('192.168.1.100', 5004, {
  customTransport: stegTransport,
  payloadType: 96,
  ssrc: 12345
});

// Use the transport with an AI stream (example)
const openai = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
const stream = await openai.chat.completions.create({
  model: "gpt-4",
  messages: [{ role: "user", content: "Tell me about steganography." }],
  stream: true,
});

// Process the AI stream
await processAIStream(stream, null, {
  transport: rtpTransport
});

// Log stats at the end
console.log('Steganography stats:', stegTransport.getStats());

Separate Transports for Reasoning

You can use separate transport channels for text and reasoning data:

import { processAIStreamToDirectSocket } from 't140llm';
import { EventEmitter } from 'events';
import * as fs from 'fs';

// Create two separate socket paths
const textSocketPath = '/tmp/llm-text.sock';
const reasoningSocketPath = '/tmp/llm-reasoning.sock';

// Clean up any existing sockets
if (fs.existsSync(textSocketPath)) fs.unlinkSync(textSocketPath);
if (fs.existsSync(reasoningSocketPath)) fs.unlinkSync(reasoningSocketPath);

// Create a separate socket for reasoning data
const reasoningSocket = processAIStreamToDirectSocket(
  new EventEmitter(), // Empty stream to initialize socket
  reasoningSocketPath
);

// Create custom reasoning metadata handler that sends to separate socket
const handleMetadata = (metadata) => {
  if (metadata.type === 'reasoning') {
    reasoningSocket.write(JSON.stringify({
      type: 'reasoning',
      content: metadata.content
    }) + '\n');
  }
};

// Process the main text stream with the reasoning handler
const textSocket = processAIStreamToDirectSocket(
  llmStream,
  textSocketPath, 
  {
    handleMetadata: true,
    metadataCallback: handleMetadata
  }
);

// This allows different clients to connect to each socket:
// - One client can show the final LLM text output
// - Another client can show the reasoning process

Forward Error Correction (FEC)

The library includes built-in Forward Error Correction to recover from packet loss during transmission. Enable it by setting enableFec: true in your RTP configuration:

await processAIStreamToRtp(stream, remoteAddress, remotePort, {
  enableFec: true,
  fecInterval: 5, // Send FEC packets every 5 data packets
});

Backspace Processing

Some LLMs might emit backspace characters during text generation. The library can handle these automatically:

await processAIStream(stream, websocketUrl, {
  processBackspaces: true,
});

Rate Limiting

You can control the transmission rate of packets:

await processAIStreamToRtp(stream, remoteAddress, remotePort, {
  rateLimit: 30, // Limit to 30 packets per second
});

Redundancy

For improved reliability, you can enable packet redundancy:

await processAIStreamToRtp(stream, remoteAddress, remotePort, {
  redundancy: 2, // Send each packet twice
});

Custom RTP Configuration

You can customize various RTP parameters:

await processAIStreamToRtp(stream, remoteAddress, remotePort, {
  payloadType: 98,     // Custom payload type (default: 96)
  ssrc: 12345678,      // Custom SSRC (default: random)
  sequenceNumber: 100, // Starting sequence number (default: random)
  timestamp: 0,        // Starting timestamp (default: current time)
});
