Re: [mediacapture-record] Add keyframe interval support. (#216)

> To my understanding most encoders configure keyframe intervals in number of frames, not based on time.

On macOS/iOS you have the choice.
In many case, there is the possibility to mark a specific frame to be encoded as key frame (see https://www.w3.org/TR/webcodecs/#dictdef-videoencoderencodeoptions for instance).

For what is worth, WebKit is doing the following: a key frame every 2 seconds or 60 frames, whichever comes first.
I wonder whether we could provide suggestions to implementors for the default value, as a non normative statement for instance.

Getting a better sense of the use case to go with either time or/and frame count would be good.
