Photoprism transcoding Intel QuickSync /dev/dri

[chicungunya]

Hello,
I had the passtrough of my /dev/dri

This is my conf file of my LXC :

arch: amd64
cores: 4
features: keyctl=1,nesting=1
hostname: photoprism
memory: 8192
mp0: /lxc/data,mp=/mnt/data
net0: name=eth0,bridge=vmbr0,gw=192.168.1.1,hwaddr=BC:24:11:13:7D:BB,ip=192.168.1.112/24,type=veth
onboot: 1
ostype: debian
rootfs: local-lvm:vm-112-disk-0,size=8G
swap: 512
tags: proxmox-helper-scripts
unprivileged: 1
lxc.cgroup2.devices.allow: c 226:128 rwm
lxc.cgroup2.devices.allow: c 29:0 rwm
lxc.mount.entry: /dev/dri dev/dri none bind,optional,create=dir
lxc.mount.entry: /dev/dri/renderD128 dev/renderD128 none bind,optional,create=file

When I do ls -l /dev/dri in my PVE I have this :

root@pve:~# ls -l /dev/dri
total 0
drwxr-xr-x 2 root root 80 Feb 21 12:37 by-path
crw-rw---- 1 root video 226, 0 Feb 21 12:37 card0
crw-rw---- 1 root render 226, 128 Feb 21 12:37 renderD128

And in my container :

root@photoprism:~# ls -l /dev/dri
total 0
drwxr-xr-x 2 nobody nogroup 80 Feb 21 12:37 by-path
crw-rw---- 1 nobody nogroup 226, 0 Feb 21 12:37 card0
crw-rw---- 1 nobody nogroup 226, 128 Feb 21 12:37 renderD128

I miss something right?

But how to tell to Photoprism now? I don't know if the HW transcoding is working? In the log of Photoprism I have : 2024-02-23 12:23:24 INFO libx264: created Name.mpg.avc [5m46.261050656s] I'm pretty sure it is software transcoding right?

In my /opt/photoprism/config/.env file I put :

PHOTOPRISM_FFMPEG_ENCODER='intel'
PHOTOPRISM_INIT='intel tensorflow'

Thanks a lot!
