I'm currently using libavcodec and I have specified x11grab.
When running normally, I can even capture 60 FPS, but when I switch to a 3d application full screen (i.e. game running with Vulkan or OpenGL), the famebuffer is basically empty.
Again, not asking about encoding with nvenc or vaapi, but is there any other source I should specify instead of x11grab?
I would be looking at something similar to what OBS does when you specify the option Window Capture. What does OBS use in this case?
