That's an orthogonal issue to the dictionary, but I addressed it later in
my message --- I think we should use MIME types.

I think the key feature of stream recording is that it exposes the encoding
side of codecs to the Web, including codecs implemented with hardware
support. We could try to lever that into media processing APIs but I can't
see a good reason to.

“You have heard that it was said, ‘Love your neighbor and hate your enemy.’
But I tell you, love your enemies and pray for those who persecute you,
that you may be children of your Father in heaven. ... If you love those
who love you, what reward will you get? Are not even the tax collectors
doing that? And if you greet only your own people, what are you doing more
than others?" [Matthew 5:43-47]
