AssembyScript MPEG-2 Video Decoder

I've been meaning to take a deep-dive into WASM for a while now, and it seems like picking up AssemblyScript would be a fun ride. I've written a basic-profile MPEG-2 decoder in the past… Actually, a few times; most recently in Go. But I think it might be a fun learning exercise to do it targeting the web. It's most definitely not practical, in terms of performance or usability, however there are ton of fun algorithms to explore and understand in the domain of video decoding.
