Hi,
I tried to use wayland plugin, but it crashes. Can I provide any info to help with the issue? I use fedora 30/gnome/wayland. The crash ahppend on downloaded plugin and on locally build as well.

You say you're using GNOME, but wlrobs was written for wlroots based compositors (sway, wayfire, etc.) so it won't work on GNOME. It requires features wlroots allows for that GNOME doesn't support, unfortunately.
As cloud pointed out you cannot use wlrobs under gnome. wlrobs does screen capture using the wlr-screecopy protocol which mutter, the gnome compositor, does not implement. Without support for that protocol the only change I could make to remedy this would be to print a nice pretty error message and make the plugin return black frames as a no op so that it doesn't crash OBS. Making the plugin work under gnome currently isn't possible.
Also, next time could you please put this in a code block. The numbers in front of every line caused sr.ht to reference every single issue in this bug tracker.
