Re: [mediacapture-main] How is adaptive frame rate to be handled?

Agree.

> getUserMedia({video: { frameRate: { min: 20 }}}) should succeed if 
the camera's presently sending 30.

At the time gUM is called the camera isn't necessarily sending 
anything, is it? Are you saying how the camera *would* perform under 
present lighting conditions is observable without turning on the 
camera (and the light)?

> MediaSettings should return what the camera's drivers are currently 
giving. (I assume this is observable)

Is a live measurement expected here (and if so over what amount of 
time), or is there some internal driver attribute I'm missing? In 
[this firefox fiddle](http://jsfiddle.net/3hk82d31) which measures it 
in JS over time the frame rate seems to fluctuate a little bit.
