screencast stops in 30 seconds
I can start the screencast with Control-Shift-Alt-r key in gnome-shell. However there is the recording limitation of the 30 seconds. It can be changed by gsettings 'max-screencast-length' setting in 'org.gnome.settings-daemon.plugins.media-keys'.
I think the 30 seconds limitation is too short to take the screencast and I didn't think it's the designed limitation. Probably I think it would be more useful for the users if the limitation could be noticeable more clearly on GUI. E.g showing a progress popup window.
Or I guess the hard-coded limitation might be deleted during getting a CPU usage.
I don't know which component is the better for this issue.
