I am looking for a way to stream a single window from the laptop screen to a connected projector. Really only one window should be streamed, all others should only be displayed on the laptop itself.
I am using Fedora 36 with GNOME, the beamer is connected via VGA/HDMI.
My Laptop is an old Thinkpad X201, so OBS Studio would be too heavy for that
Thank you for the help but this is not what I mean.
I mean, that a window, which is on the desktop of the built-in Display should be ALSO visible on the projector.
The command ffplay -video_size 1200x800 -framerate 15 -f x11grab -i :0.0+0,0 -fs captures the built-in display and shows it in fullscreen mode, but on the built-in screen.
If there would be an option to specify the screen, on which the fullscreen-playback should be done, it would be perfect.
Sadly ffplay doesn’t know an option like -screen 2 as mplayer does.
Mplayer on the other hand knows the -screen 2 option, but I coudn’t do, that mplayer uses x11grab.
Is there a way to bring the fullscreen playback of the built-in display to screen 2 (=projector)?
