vaapi gpu hw intel accellaration in docker

You have to map device drivers into the container, and it should work fine, like this docker-compse.yml:

version: "3"

services:

nextpvr_amd64:

container_name: nextpvr

volumes:

- ./config:/config

- ./videos:/recordings

- ./videos:/buffer

restart: unless-stopped

ports:

- 8866:8866

- 16891:16891/udp

image: nextpvr/nextpvr_amd64:stable

devices: # import drivers for HW accel

- /dev/dri/card0:/dev/dri/card0

- /dev/dri/renderD128:/dev/dri/renderD128
