Support "screen" (all monitors) capture on wayland. This should be done by getting all drm fds and multiple EGL_DMA_BUF_PLANEX_FD_EXT to create one egl image with all fds combined.
Support pipewire screen capture?
@@ -83,4 +81,4 @@ Support screen rotation.
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.
-Fix cursor offset in kms_vaapi when capturing with multiple monitors. \ No newline at end of file
+Capture is broken on amd on wlroots. It's disabled at the moment and instead uses kms capture. Find out why we get a black screen in wlroots. \ No newline at end of file
