... mediastreamtrack.readonly read only returns a boolean value with a value of true if the track is readonly (such a video file source or a camera that settings can't be modified), false otherwise.

MediaTrackConstraints.cursor - Web APIs
see how constraints are defined in capabilities, constraints, and settings for an explanation of how to define constraints.
... usage notes you can check the setting selected by the user agent after the display media has been created by getdisplaymedia() by calling getsettings() on the display media's video mediastreamtrack, then checking the value of the returned mediatracksettings object's cursor object.
... for example, if your app needs to alter the stream by inserting a representation of the cursor position if the stream doesn't include the rendered cursor, you can determine the need to do so by using code like this: let insertfakecursorflag = false; if (displaystream.getvideotracks()[0].getsettings().cursor === "never") { insertfakecursorflag = true; } following this code, insertfakecursorflag is true if there's no cursor rendered into the stream already.
...in addition, see example: constraint exerciser in capabilities, constraints, and settings for a complete example showing how constraints are used.

MediaTrackConstraints.displaySurface - Web APIs
see how constraints are defined in capabilities, constraints, and settings for an explanation of how to define constraints.
... usage notes you can check the setting selected by the user agent after the display media has been created by getdisplaymedia() by calling getsettings() on the display media's video mediastreamtrack, then checking the value of the returned mediatracksettings object's displaysurface object.
... for example, if your app needs to know that the surface being shared is a monitor or application—meaning that there's possibly a non-content backdrop—it can use code similar to this: let mayhavebackdropflag = false; let displaysurface = displaystream.getvideotracks()[0].getsettings().displaysurface; if (displaysurface === "monitor" || displaysurface ==="application") { mayhavebackdropflag = true; } following this code, mayhavebackdrop is true if the display surface contained in the stream is of type monitor or application; either of these may have non-content backdrop areas.
...in addition, see example: constraint exerciser in capabilities, constraints, and settings for a complete example showing how constraints are used.

Using the Screen Capture API - Web APIs
there are three new constraints added to mediatrackconstraints (as well as to mediatracksupportedconstraints and mediatracksettings) for configuring a screen capture stream: cursor indicates whether or not to capture the mouse cursor, and if so, whether to do so all the time or only while the mouse is in motion.
... function stopcapture(evt) { let tracks = videoelem.srcobject.gettracks(); tracks.foreach(track => track.stop()); videoelem.srcobject = null; } dumping configuration information for informational purposes, the startcapture() method shown above calls a method named dumpoptions(), which outputs the current track settings as well as the constraints that were placed upon the stream when it was created.
... function dumpoptionsinfo() { const videotrack = videoelem.srcobject.getvideotracks()[0]; console.info("track settings:"); console.info(json.stringify(videotrack.getsettings(), null, 2)); console.info("track constraints:"); console.info(json.stringify(videotrack.getconstraints(), null, 2)); } the track list is obtained by calling getvideotracks() on the capture'd screen's mediastream.
... the settings currently in effect are obtained using getsettings() and the established constraints are gotten with getconstraints() html the html starts with a simple introductory paragraph, then gets into the meat of things.
