Yeah for Safari support I'm using polyfills; it sucks.

- libav.js for AudioEncoder/AudioDecoder. - QMux over WebSockets for WebTransport.

Both are NPM packages if you want to use them. @kixelated/libavjs-webcodecs-polyfill and @moq/qmux

26.4 removes the need for both so there's hope!

Thanks!

Any idea what Firefox is waiting for? To me those lines I quoted seem entirely arbitrary, and a skim through bugzilla didn't help.
