aspectRatio property is a double-precision floating-point number indicating the aspect ratio of the
MediaStreamTrack as currently configured. This lets you determine what value was selected to comply with your specified constraints for this property's value as described in the
MediaTrackConstraints.aspectRatio property you provided when calling either
If needed, you can determine whether or not this constraint is supported by checking the value of
MediaTrackSupportedConstraints.aspectRatio as returned by a call to
MediaDevices.getSupportedConstraints(). However, typically this is unnecessary since browsers will simply ignore any constraints they're unfamiliar with.
var aspectRatio = MediaTrackSettings.aspectRatio;
A double-precision floating-point number indicating the current configuration of the track's aspect ratio. The aspect ratio is computed by taking the track's width, dividing by its height, and rounding the result to ten decimal places. For example, the standard 16:9 high-definition aspect ratio can be computed as 1920/1080, or 1.7777777778.
