ffmpeg-metadata

What problem does it solve?

ffmpeg-metadata automates the tedious process of applying and updating metadata, chapters, and cover art across common media containers using FFmpeg, reducing manual editing and ensuring consistency.

Core Features & Use Cases

• Set container and per-stream tags with ffmpeg metadata flags, including per-stream language and track titles.
• Create and apply chapters either from an ffmetadata file or via inline timestamp entries.
• Embed cover art, attach fonts to MKV, and manage dispositions to control playback behavior.
• Strip metadata and chapters for privacy or clean handoffs, while preserving the rest of the media.
• Manage Matroska edition entries and maintain language tagging across streams.

Quick Start

Provide an input media file, specify the desired metadata or chapters, and the skill will compose and run the appropriate ffmpeg commands to update the file in place or generate a new tagged output.
