MediaStreamTrack: getCapabilities() method
The getCapabilities() method of
the MediaStreamTrack interface returns a
MediaTrackCapabilities object which specifies the values or range of
values which each constrainable property, based upon the platform and user
agent.
Once you know what the browser's capabilities are, your script can use
applyConstraints() to ask for the
track to be configured to match ideal or acceptable settings. See Capabilities, constraints, and settings for details on how to work with constrainable properties.
