SOLVED: Hevc

[crick3t]

Hi everyone, I'm very new to anything other than Windows (and even there I've never particularly touched the terminal) and taking advantage of the start of the Christmas break I decided to venture into the world of homelabs, with pretty much the sole purpose to use if for Jellyfin.

I installed debian 12 and casaOS on an old laptop equipped with an i7 4720HQ and an NVIDIA 950M. From casaOS I then set the shared folder to which I linked Jellyfinn and everything works fine... If it weren't for the hardware acceleration for transcoding.

I installed the nvidia drivers and they appear correctly, I tried running the

Code:

nvidia-smi

command while transcoding a video and ffmpeg5 appears in the processes, so that should work too.
The only thing I couldn't do, which I guess is the cause of my problems, was to insert jellyfin into the render and video groups. I tried following the various online guides to do this but every time I do

Code:

ls -l /dev/dei

jellyfin doesn't appear in the groups.

I no longer know what to do, and my inability makes everything slower and more frustrating, if anyone can help me I would be extremely grateful.

PS. It's also the first time I use a forum actively, so if I did anything against the rules I'm sorry in advance

It depends if your laptop is setup to only enable one GPU at a time. /dev/dri is where your INTEL iGPU would appear. Not the Nvidia GPU.

Of the GPUs available to you, I'd use the GTX 950M over the Intel iGPU in the 4720HQ. If your Nvidia GPU is setup and shows up with nvidia-smi I would just call it a day and proceed with our Nvidia hardware acceleration guide.

Also, neither the Intel iGPU nor the Nvidia GPU can encode or decode HEVC.

It does show up with nvidia-smi, but I'm not sure if I have enabled correctly hardware acceleration. Are you sure the 950 doesn't support HEVC? It looks to me like it does support HEVC 4:2:0 up to 10bit (https://developer.nvidia.com/video-encod...matrix-new)

For encoding, yes. But, for some reason, not decoding. The check boxes at the top of the Playback dashboard are for decoding.

Thanks, I didn't understood that! A bit of a bummer but it's not the end of the world
