+## ⚡ FFmpeg 8.0 Enhanced
+Now with FFmpeg 8.0+ support featuring hardware acceleration and performance improvements!
+- **5-10x faster encoding** with NVIDIA, Intel, or AMD GPUs
+- **Docker-ready** with Linux builds
+- **Configurable options** for different scenarios
+- 📖 **[See FFMPEG_SETUP.md for detailed setup instructions](FFMPEG_SETUP.md)**
+
 ## Requirements
 - [Python 3](https://www.python.org/downloads/)
 - [Streamlink](https://github.com/streamlink/streamlink)
+- [FFmpeg 8.0+](https://ffmpeg.org/download.html) (see [FFMPEG_SETUP.md](FFMPEG_SETUP.md) for platform-specific versions)
 ## Getting started
 1. Install Python 3.x
 2. Install Streamlink 5.1.x
