Hi

I'm new to proxmox but not to linux
I followed the tutorial https://forum.proxmox.com/threads/plex-hw-transcoding-lxc-and-jasper-lake-igpu-passthru.116163/ , but I can't get hw transcoding working

I'd love If anybody could help me get it working or at least tell me what I did wrong or what I'm missing

Before I tried proxmox, I had working my plex server directly with docker. Right now everything is working (nfs, remote access, etc) except hw transcoding

I fixed I few things but the output was the same

I even tried ubuntu just in case the driver/implementation was different, but apart from the render group number everything was the same

--

in the line below I missed the directory dri on the second argument (was dev/renderD128)
Code: 
lxc.mount.entry: /dev/dri/renderD128 dev/dri/renderD128 none bind,optional,create=file

added in debian
Code: 
lxc.hook.pre-start: sh -c "chown 0:106 /dev/dri/renderD128"
and in ubuntu
Code: 
lxc.hook.pre-start: sh -c "chown 0:108 /dev/dri/renderD128"
to fix the group assigned (sgx in debian and ssl-cert in ubuntu)
 
couldn't find the way, so I tried with a VM (debian) and everything worked fine
 
This is great! After hours of research and try-and-error I found your post and it worked like a charm! Thank you!
 
Thank you so much! I was having the same issue and had discovered the sgx group being set and changing it to render solved it but on a reboot it would revert the change. Setting it in the lxc conf file now keeps it as render on reboots!
