MediaTrackSettings: width property

View on MDN ↗

The MediaTrackSettings dictionary’s width property is an integer indicating the number of pixels wide MediaStreamTrack is currently configured to be. This lets you determine what value was selected to comply with your specified constraints for this property’s value as described in the width property you provided when calling either getUserMedia() or applyConstraints().

If needed, you can determine whether or not this constraint is supported by checking the value of width as returned by a call to getSupportedConstraints(). However, typically this is unnecessary since browsers will ignore any constraints they’re unfamiliar with.

Value

An integer value indicating the width, in pixels, of the video track as currently configured.

Examples
