frameRate property
The MediaTrackSupportedConstraints dictionary's frameRate property
is a read-only Boolean value which is
present (and set to true) in the object returned by
MediaDevices.getSupportedConstraints if and only if the supports the
MediaTrackConstraints.frameRate constraint.
If the constraint isn't supported, it's not included in the list, so this
value will never be false.
The frameRate constraint can be used to establish acceptable upper and
lower bounds on the video frame rate for a new video track, or to specify
an exact frame rate that must be provided for the request to succeed.
Checking the value of this property lets you determine if the user agent
allows constraining the video track configuration by frame rate. See the
example to see how this can be used.
