Quoting: ShmerlAlso, I wonder what's the method in the Wayland session where x11grab is not an option. I suppose there must be some ffmpeg / Pipewire integration for that?

kmsgrab as mentioned in the thread previously, skips those nasty roundtrips to the CPU.

That doesn't sound like a good method - it requires some explicit permissions access that's not on compositor level. The proper way would be something like pipewire and access controlled by the compositor. For less trips, it can be using DMA-BUF.
