DesktopCapturerSource
Properties
An icon image of the application that owns the window or null if the source has a type screen. The size of the icon is not known in advance and depends on what the application provides.
A unique identifier that will correspond to the id
of the matching Display returned by the Screen API. On some platforms, this is equivalent to the XX
portion of the id
field above and on others it will differ. It will be an empty string if not available.
The identifier of a window or screen that can be used as a chromeMediaSourceId
constraint when calling navigator.getUserMedia
. The format of the identifier will be window:XX:YY
or screen:ZZ:0
. XX is the windowID/handle. YY is 1 for the current process, and 0 for all others. ZZ is a sequential number that represents the screen, and it does not equal to the index in the source's name.
A thumbnail image. Note: There is no guarantee that the size of the thumbnail is the same as the thumbnailSize
specified in the options
passed to desktopCapturer.getSources
. The actual size depends on the scale of the screen or window.
