About:
Yamdi is a command-line utility that inserts metadata into FLV (Flash Video) files. It creates a proper onMetadata tag which is essential for streaming servers and players to correctly handle video duration, keyframes, and other properties. This ensures compatibility and enables features like seeking for server-side recorded streams.
Key Features:
  • Inserts comprehensive onMetadata tags into FLV files
  • Adds cue points for keyframes to enable seeking
  • Supports server-side recording workflows
  • Lightweight and fast command-line interface
Use Cases:
  • Preparing FLV files for streaming with Wowza or Red5 servers
  • Fixing missing metadata in recorded Flash video streams
  • Batch processing FLV files for web video platforms
Alternatives:
  • flvtool2 – Similar FLV metadata manipulation tool, but Yamdi is often preferred for its simplicity and reliability
  • ffmpeg – More comprehensive video tool that can also modify metadata, but Yamdi is specialized for FLV
