Lastest AMD GPU does realtime encoding with AV1. It has directly an ASIC block for that. Just mmap the video engine command circular buffer, get some dma buffers, get a interrupt circular buffer, and you are good to go (I think the dma-buffer sync framwork between drivers and user space is still a WIP, and I dunno how the interrupt circular buffer is handled).
