@ -80,7 +80,6 @@ Support "screen" (all monitors) capture on wayland. This should be done by getti
Support pipewire screen capture?
Support screen rotation in amd/intel/nvidia wayland.
Support wlroots dmabuf screen recording, because it doesn't require root access unlike kms grab.
Capture cursor on amd/intel wayland without xwayland.
When nvidia supports hardware cursor then capture the cursor. Right now the cursor is captured because it's a software cursor so it's composed on the dma buf.
CPU usage is pretty high on AMD/Intel/(Nvidia(wayland)), why? opening and closing fds, creating egl, cuda association, is slow when done every frame. Test if desktop portal screencast has better performance.
