MediaTrackSettings: width property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2017.
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 MediaTrackConstraints.width property you
provided when calling either getUserMedia()
or MediaStreamTrack.applyConstraints().
If needed, you can determine whether or not this constraint is supported by checking
the value of MediaTrackSupportedConstraints.width as returned by a call
to MediaDevices.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
See the Constraint exerciser example.
