these i18n var names should be camel case. Also, please keep it consistent
whether "mediastream" is one word or two (looks like it should be two:
mediaStream)

I realize that much of this file fails to follow this advice, but it should.

I checked the naming style for the existing code, but could not find any one
camelcase, and I use mediastream because of similar case like mouselock. Could
you please confirm it?

In case mediastream is a bad name anyway, I can consider changing it to media.

examples of i18n-content="camelCase" in this file: L293, L288, L284, L273, etc.

mouselock is bad, it should be mouseLock. It's not uncommon to have
inconsistencies like this (SpellCheck vs. Spellcheck, AutoFill vs Autofill,
etc.), but they are all terribly annoying. I don't really care between
MediaStream/mediaStream/media_stream and Mediastream/mediastream/mediastream,
but it should be consistent.

Thanks for pointing out, this file is indeed misled, and hard to find a
consistent style. I changed them to camelcase, please double check.
