How do you decode video from a data channel?

Getting encoded video bytes from a buffer onto the screen while using hardware video decoding and without a multi-second lag I haven't been able to do in either safari or chrome - any tips?

wasm ffmpeg -> canvas

Granted, not tested on Safari

Can you do 1080p60 video on mobile with wasm ffmpeg? I'd imagine it to have severe performance issues, since WASM is pretty bad for vector and bit twiddling operations heavily used in video codecs, and writing to a canvas on every frame requires the javascript (main) thread rather than being possible to do on the compositor thread (where videos normally decode and run) which means it'll end up janky if any other javascript runs at all.

Even basic canvas animations on the main thread like the dinosaur game (chrome offline page) are pretty janky, and they aren't doing much per frame at all.
