This is awesome! Just so I understand, you've compiled ffmpeg into wasm and run it in-browser?

yes! This is all in browser. It's literally just ffmpeg compiled into wasm.

The wonder of Javascript right?

This is beautiful!!

Do you have a write-up or any details on how you did it? There's quite a few things I'd like to apply said treatment to :D

there's a guy's github that did most of the work for me. It's open source, google around for ffmpeg wasm.

what are the things you wanna do?

The one I'm trying to do most recently is to compile bitcoin's bx[1] to wasm, so it can be run in the browser. It's not a crypto-related project, I primarily need the mnemonic generation code so I can generate mnemonics from passphrases for more general-purpose reasons.

Two reasons I'm thinking of getting it done in WASM: First is of course, not to roll my own crypto. Second is that if you're asking someone to generate a private key to use themselves, sending ANY information to a server is a big no.

Honestly I'd appreciate any thoughts or advice anyone has, I'm open!
