kmsgrab is a method of "zerocopy" screen capture, video stream will not copying between cpu and gpu so it can reduce latency. ffmpeg and a obs plugin has already implemented this. some discussion can be found at https://github.com/kokoko3k/ssh-rdp/issues/2 and https://obsproject.com/forum/threads/experimental-zero-copy-screen-capture-on-linux.101262/ it also working under wayland, https://github.com/loki-47-6F-64/sunshine/issues/44 can be resolved at same time.
