Failed to enable hardware acceleration in docker

[lyphix 0]

Hi guys, I am having trouble with the hardware acceleration in docker. I'm using the integrated graphics card of the Intel N100 and the system is Ubuntu server 22.04 LTS. 

My emby is  4.7.14.0

With the commands:

getent group video | cut -d: -f3, I got 44

getent group render | cut -d: -f3, I got 109

So Here is my docker compose:

emby:
    image: emby/embyserver:latest
    container_name: emby
    environment:
      - UID=1000
      - GID=100
      - GIDLIST=44,109
      - TZ=Asia/Shanghai
    volumes:
      - /root/emby/config:/config
      - /root/emby/cache:/cache
      - /root/media:/media
    devices:
      - /dev/dri:/dev/dri
    ports:
      - 8096:8096
    restart: unless-stopped

After emby started, I found several errors in hardware_detection:

Devices": [
        {
            "DeviceIndex": 0,
            "DeviceInfo": {
                "VendorName": "Intel Corporation",
                "DeviceName": "Alder Lake-N [UHD Graphics]",
                "SubsytemVendorName": "Intel Corporation",
                "VendorId": 32902,
                "DeviceId": 18129,
                "SubsytemVendorId": 32902,
                "SubsytemDeviceId": 29296,
                "DevPath": "/sys/bus/pci/devices/0000:00:02.0",
                "DrmCard": "/dev/dri/card0",
                "DrmRender": "/dev/dri/renderD128",
                "IsEnabled": 1,
                "IsBootVga": 1,
                "Error": {
                    "Number": -1,
                    "Message": "Failed to initialize VA /dev/dri/renderD128. Error -1"
                }
            }
        }
    ],

I also tried:

ffmpeg -hwaccel vaapi -hwaccel_output_format vaapi -i input.mp4 -vf 'format=nv12|vaapi,hwupload' -c:v h264_vaapi output_VAAPI.mp4

It works in Ubuntu

but not in Docker:

Could you give me any advice?

Hi, are you able to try the 4.8 beta server and see how that compares? Thanks.
