Would be cool to see something client side using ffmpeg in browser, like https://github.com/ffmpegwasm/ffmpeg.wasm Found a previous post from someone using that lib https://news.ycombinator.com/item?id=26580333

Looks to be using https://github.com/ffmpegwasm/ffmpeg.wasm In the future https://www.w3.org/TR/webcodecs/ may allow for a native API to do this.

Ffmpeg can run in any browser now… https://github.com/ffmpegwasm/ffmpeg.wasm Maybe can package that up and monetize but… maybe hard to corner a market

In What xAAS (x-As-A-Service) would you like to build?

Funny to see this mentioned. Just this morning I was struggling to get ffmpeg-wasm working on Firefox. It should theoretically be possible with HTTPS and configured headers: Cross-Origin-Opener-Policy: same-origin Cross-Origin-Embedder-Policy: require-corp Related links: Does not work in Firefox 79+ because SharedArrayBuffer is undefined - https://github.com/ffmpegwasm/ffmpeg.wasm/issues/106 SharedArrayBuffer: Planned changes to shared memory - https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe...
