Absolutely. Audio extraction, format conversion, loudness normalization are all there. If you have a specific TTS pipeline in mind the raw FFmpeg mode should handle most of it.

WASM SIMD is 128-bit wide as dtf noted, so AVX-512 won't apply here. Longer term, WebGPU could be a more interesting path for compute acceleration in the browser than SIMD widening.

~4x slower than native for encoding, which is acceptable for clips under 5 mins. No hardware encoding -- WASM is CPU-bound, for now. WebCodecs could bridge that gap in future.

It already does -- trim, crop, concatenate, picture-in-picture, side-by-side, subtitle embedding. What would you add? Let's make it happen.

Fair. The emojis are a style choice -- I find them useful as visual anchors when scanning a long feature list. The code is in docs/ either way.

The browser-as-runtime has one property nothing else has: zero install on every OS. For sensitive files for medical, legal, personal. It's also the only architecture where you can verifiably prove data never left the device. My persona

This is a great addition! You can use the raw ffmpeg mode to do this currently if you know the flag syntax

Whisper.cpp for local speech transcription and WebLLM for in-browser LLM inference follow the same pattern. We're calling this the Web-CLI architecture. A paper is in progress.

Thank you. This works entirely offline. I work in a univ setting where I cannot easily install software for classes. This can be used as a regular app once installed as a PWA. Even the ffmppeg lib is cached. Once installed it looks like any

Go here for live demo: https://tejaswigowda.com/ffmpeg-webCLI/ Thanks for all the comments. Changed upload icon to floppy disk to make it clear that all data stays local.
