I built typed-ffmpeg, a Python package that lets you build FFmpeg filter graphs with full type safety, autocomplete, and validation. It’s inspired by ffmpeg-python, but addresses some long-standing issues like lack of IDE support and fragile CLI strings.

What’s New in v3.0: • Source filter support (e.g. color, testsrc, etc.) • Input stream selection (e.g. [0:a], [1:v]) • A new interactive playground where you can: • Build filter graphs visually • Generate both FFmpeg CLI and typed Python code • Paste existing FFmpeg commands and reverse-parse them into graphs

Playground link: https://livingbio.github.io/typed-ffmpeg-playground/ (It’s open source and runs fully in-browser.)

The internal core also supports converting CLI → graph → typed Python code. This is useful for building educational tools, FFmpeg IDEs, or visual editors.

I’d love feedback, bug reports, or ideas for next steps. If you’ve ever struggled with FFmpeg’s CLI or tried to teach it, this might help.

Thanks! — David (maintainer)
