Re: CfC: Should WebCodecs be exposed in Window environments?

I support exposing VideoEncoder, AudioEncoder, VideoDecoder, and
AudioDecoder in Window contexts at this time

1. It is much easier to learn and adopt new APIs when they are available on
Window. You can play around with it a lot more easily, particularly, inside
dev-tools.
2. Debugging code outside a Worker is a lot easier. For Video.js, we have a
process that inlines our Worker code to allow for easier debugging. This
won't be an option if WebCodecs won't be available on Window. If the
tooling around debugging in a Worker were better, I'd put this at a lower
priority, but given the current state, this is a huge one for us.
3. Workers increase latency where you need to shuttle things between the
main thread and the worker. Particularly in low latency scenarios. Since we
already do some work in the main thread, needing to shuttle things between
workers will add a lot of overhead.
4. Making Worker and Window contexts similar is helpful.
