I can see this is a GitHub repository for an M3U8 proxy server designed to handle CORS errors when streaming HLS (HTTP Live Streaming) files. Let me create a Next.js implementation of an M3U8 proxy server that can handle CORS issues for streaming media.

I've created a Next.js implementation of the M3U8 proxy server based on the GitHub repository you shared. This application provides:

Key Features:

1. CORS-Free M3U8 Streaming: Proxies M3U8 playlist files and handles CORS headers properly
2. User-Friendly Interface: Clean web interface to generate proxy URLs
3. URL Processing: Automatically converts relative URLs in M3U8 files to absolute URLs
4. Segment Proxying: Additional endpoint for proxying video segments if needed

How it works:

1. Main Proxy Endpoint (/api/proxy): Fetches M3U8 playlist files and adds proper CORS headers
2. Segment Proxy Endpoint (/api/segment): Can proxy individual video segments if needed
3. URL Processing: Automatically handles relative URLs in M3U8 files by converting them to absolute URLs
4. Web Interface: Provides an easy way to generate proxy URLs

Usage:

1. Enter your original M3U8 URL in the input field
2. Click "Generate Proxy URL" to create a CORS-free version
3. Use the generated proxy URL in your video player or application
4. The proxy will handle all CORS issues and serve the content properly

The server adds all necessary CORS headers and processes M3U8 content to ensure compatibility with web-based video players that would otherwise be blocked by CORS policies.
