LGTM3
At a higher level, it would be great for AV1/VP9 encode to end up in
something like Interop. It makes me sad to be adding a vote here to
enable a closed format when open ones are better.

<https://wpt.fyi/results/mediacapture-record?label=master&label=experimental&aligned&q=mp4>
are the relevant tests. LGTM assuming all of these tests pass with
MediaRecorderEnableMp4Muxer enabled. If that's not the case, is
there some functionality that won't be supported initially?

Yoav,
in WebRTC land "we have a sample for that"

Discovery currently happens
with isTypeSupported but it seems the WG just
decided to deprecate that:

(not sure how I feel about that, I'd rather
nuke MediaRecorder entirely in favor of
WebCodecs + IndexedDB)

Thanks! That's very useful! :)
What's the feature detection story? How
can developers know which formats are
supported?

Could you maybe write a short

what it is that we want to ship,
what it would help developers
achieve, how we envision them
using this feature, etc.?
