MediaTrackSettings: width property
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.
