I'm trying get screen capture through a SSH connection. In this SSH connection, I'm using the root user.
I found that after executing this command:
screencapture -t jpg -S /test.jpg
the jpg file I got is all black. If I do this in the normal way (not through SSH), then I can get the screen capture successfully.
What could be causing this?
There's a command line client for the OS X screen capturing? Gosh, didn't know that.
I wonder what the man page says…
SECURITY CONSIDERATIONS
To capture screen content while logged in via ssh, you must launch screencapture in the same mach bootstrap hierarchy as loginwindow:
PID=pid of loginwindow sudo launchctl bsexec $PID screencapture [options]
