Within the getDisplayMedia permissions dialog, the user gets to choose whether they share the whole screen or just a window.
To stream just part of the screen, you could copy the video to a canvas element and crop it there, then export the canvas back to a MediaStream using the captureStream method.
As for streaming to RTMP, that is not something built into the browser. You’ll need to stream to a server using webRTC or web sockets and then have the server turn it into a RTMP stream.

getDisplayMediaas I show in this post on desktop capture in Edge. This works for Chrome now too, though you used to need an extension. Firefox supports desktop capture, but with an non-standard methods.Once you capture the media stream, you can use the
MediaRecorderjust like in this post.ok i got my response for the specific window capture
Maybe you will know this too so !
