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 simply ignore any constraints they're unfamiliar with.
Syntax
var width = MediaTrackSettings.width;
Value
An integer value indicating the width, in pixels, of the video track as currently configured.
Example
See Example: Constraint exerciser in Capabilities, constraints, and settings for an example.
