Media Capture and Streams defines MediaTrackCapabilities

dictionary MediaTrackCapabilities {
  ULongRange width;
  ULongRange height;
  DoubleRange aspectRatio;
  DoubleRange frameRate;
  sequence<DOMString> facingMode;
  sequence<DOMString> resizeMode;
  ULongRange sampleRate;
  ULongRange sampleSize;
  sequence<boolean> echoCancellation;
  sequence<boolean> autoGainControl;
  sequence<boolean> noiseSuppression;
  DoubleRange latency;
  ULongRange channelCount;
  DOMString deviceId;
  DOMString groupId;
};

This dictionary is extended in the following specifications:

• MediaStream Image Capture

  
  
  partial dictionary MediaTrackCapabilities {

    MediaSettingsRange   pan;
    MediaSettingsRange   tilt;
    MediaSettingsRange   zoom;
  
    sequence<boolean> torch;
  };
