No support for codec h264

Plex Media Server NAS & Devices
1

Server Version#: 1.41.3.9314
Player Version#: 4.141.0

After many days of waiting for items to arrive and digging through guides across the web, I finally have my plex installation completed…or so I thought. For the record, I’ve had plex working just fine on my TrueNAS jail for many years now but for a few reasons, one of them mainly wanting GPU transcoding, I moved the installation over to a docker container on a Proxmox VM (Ubuntu). Everything is moved over and plex is working fine. As of this writing, I have 2 people streaming direct.

I was able to install my ASRock Arc A310 card on my Supermicro X10DRC-LN4+ motherboard with E5-2640 v4 CPU and a crap ton of DDR4 ECC RAM.

Ive followed this guide to get my card passed through to the VM. On the host, I see

Kernel driver in use: vfio-pci

On the VM, I see:

01:00.0 VGA compatible controller: Intel Corporation DG2 [Arc A310] (rev 05) (prog-if 00 [VGA controller])
        Subsystem: ASRock Incorporation DG2 [Arc A310]
        Physical Slot: 0
        Flags: bus master, fast devsel, latency 0, IRQ 42
        Memory at 80000000 (64-bit, non-prefetchable) [size=16M]
        Memory at 380000000000 (64-bit, prefetchable) [size=256M]
        Expansion ROM at <ignored> [disabled]
        Capabilities: <access denied>
        Kernel driver in use: i915
        Kernel modules: i915, xe

My compose.yml looks like so:

---
services:
  plex:
    container_name: plex
    privileged: true
    image: plexinc/pms-docker
    restart: unless-stopped
    devices:
      - /dev/dri:/dev/dri  # Pass the entire /dev/dri directory
    environment:
      - TZ=America/New_York
    network_mode: host
    volumes:
      - /home/dangerisgo/plex/config:/config
      - /mnt/plex/transcode:/transcode
      - /media:/media
      - /photos:/photos

I can see the card in plex and select it but plex does not use the card for transcoding. Looking through the logs, I see this snippet:

I’m not sure what “No support for codec h264 profile 100.” means but after doing some google searching, its essentially came up with nothing. Any help would be awesome!

As an update, I also tried installing it directly on the VM with the official installer, not running through docker, and I get the same results.

There is no H.264 profile 100.
The highest is 5.1

If you have h.264 identifying it’s level 100 then whoever touched it last doesn’t know what they’re doing.

recommend replacing the file.

Thanks for your reply Chuck. I’ve tried multiple files from various release groups all with the same result.

No support for codec vc1 profile 3.

Is another one I got on a different movie. I also got the h264 profile 100 on several other movies.

When trying to play a 4k HEVC movie, I got the following:

No support for codec hevc profile 2.

As a follow-up, there is a profile 100 in h.264: Advanced Video Coding - Wikipedia

Let’s get a big hammer :smiling_imp:

  1. Stop Plex
  2. In the terminal, get into the “Plex Media Server” directory
  3. Now go into the “Codecs” directory
  4. You’ll see subdirectories for the codecs – DELETE THEM
  5. –DO NOT– delete the .device_id file. This is your license key.
  6. Restart PMS

As for what to expect from your CPU:

  1. I have the E5-2690 v4 and 256 GB ECC RAM
  2. It will NOT do any hardware transcoding . The CPU doesn’t have it.
  3. What you’re showing me is that you have an ARC GPU.
  4. Plex doesn’t support them
  5. If you want to use it, it’s your responsibility to install Intel’s VAAPI drivers for the card.

I tried your big hammer steps but unfortunately, they did not work :frowning:
Do you have any other suggestions? Perhaps a bigger hammer??

Here’s more: I got a P400 off ebay today and put that in my system. Deleted the intel drivers and installed the official NVIDIA drivers. No go. Here is a snippet of the log:

Kernel driver in use: nvidia

Before the nvidia official drivers, I tried the ubuntu repository nvidia drivers. Same output as above.
I disabled secure boot on this most recent try since the official drivers complained about it, but that didnt affect the outcome.
I’m seriously at my wits end. I’m not sure what else to do.

My OS is Ubuntu Server 24.04.01 (non-minimized). Proxmox is 8.3.2. I completely took docker out of the equation at the moment, its the native app.

Did you do the GPU passthrough to the VM?

https://pve.proxmox.com/wiki/PCI_Passthrough

I must also ask,

  1. Why are you using Docker in a Ubuntu VM on Proxmox ?
    – You’re making it more difficult with the container in a VM

  2. Proxmox has the ‘tteck’ helper scripts which create Plex VMs very nicely .
    – I use that on my JasperLake box.

Within H.264, profiles are signaled in the Sequence Parameter Set, in a Profile Indication Field.

  • 66: Baseline profile
  • 77: Main profile
  • 88: Extended profile
  • 100: High profile
  • 110: High 10 profile
  • 122: High 4:2:2 profile
  • 244: High 4:4:4 profile

100 is just High profile, super common. My reaction at seeing 100 in the error message is that error messages are terse and something went wrong initializing the hardware for decode, not that anything is weird about the file.

I can’t help with the troubleshooting, you can trust Chuck. :slight_smile:

Yes, I did everything on that list.

And 1. I do use docker but not for these testing. All of this testing has been native. I do docker because I found it easier to update and work with. I know immediately where the data dir is, and very easy to move it around if/when I have to
2. I have never heard of that before. I’ll look into it!

As another update, I tried creating a new VM of Windows 10 following this guide and I’m getting Error 43 in device manager with the newest drivers. I uninstalled and went back to 451 drivers from 2020 but now my system failed to boot, so I need to wipe and start again. I guess my thought process was if I can get nvidia-smi working on ubuntu (I cannot) or the card working in windows, then I would be on the right path to getting it working with plex. (When I run nvidia-smi in Ubuntu, it shows “no devices were found”)

10

I use the vetted 550 drivers from Ubuntu

sudo apt install nvidia-driver-550

If those aren’t in the Ubuntu 20 list then look what is there.

apt list | grep nvidia-driver

the sequence here is:

  1. Pass the physical GPU through to the VM (Proxmox doesn’t touch it)
  2. Let Ubuntu install the host drivers in the VM
  3. Confirm the drivers see the card (nvidia-smi)

That output shows the Nvidia is not being passed into the VM.

It should also show this way:

The ASPEED is the IPMI from the SuperMicro. It can’t be used for any of this.

When in the VM, dpkg -l | grep nvidia shows nothing installed ?

I had a problem with my drivers once and I had to completely remove everything and start fresh with it

I’m not passing the ASPEED to the VM, so I shouldn’t have to worry about it, right?

16

550.120 is correct.

No, don’t worry about the ASPEED. We only use it for the IPMI console.

There is something stupid happening with ProxMox not passing it.

This is where my ability to help ends. My Proxmox system is a 4x4" mini PC nuc which I purchased to try and help

17

What has your experience been with installing plex in an LXC? A quick google search said people have to install the nvidia drivers on the host. Thoughts on that route?

What about any sort of isolation with a VM, like how one debugs with bad components?

18

I use LXCs extensively.

  1. Install the Nvidia drivers on the host (from a terminal / console window )
  2. Add the GPU to the LXC

For me, it’s as simple as this (I wrote a script I do it so much)

[chuck@lizum lxc.2002]$ cat add-gpu

#
# Argument #1 is LXC container to add

[ -z "$1" ] && "Error: missing container name" && exit 1

if [ "$(lxc list | grep "$1")" == "" ]; then
  echo "Error: Unknown container name '$1'"
  exit 2
fi

# Make certain /dev/dri/renderD128 exists
if [ ! -e /dev/dri/renderD128 ]; then
  echo Error:  This host does not have hardware transcoding ability /dev/dri/renderD128
  exit 3
fi

Gid="$(stat -c %g /dev/dri/renderD128)"

# Add it
lxc config device add "$1" gpu gpu gid=$Gid
[chuck@lizum lxc.2003]$

The only thing left to do is get the UID/GID alignment of the container for media and HW alignment

  1. I create a username on the host
  2. I add that username to the group which owns /dev/dri (all the nodes in it)
  3. I then set that username as the UID/GID for the container
[chuck@lizum lxc.2005]$ cat SetUser 
#!/bin/bash
# set uid and gid for container

# specified a container name  ($1)
[ -z "$1" ] && echo "Usage: $0 ContainerName Username " && exit 1
[ -z "$2" ] && echo "Error: Username missing" && exit 2

# Confirm container
if [ "$(lxc list | grep "$1")" == "" ]; then
  echo "Error: Unknown container name '$1'"
  exit 2
fi

# make sure user exists
if [ "$(id "$2")" = "" ]; then

  echo \"$1\" is not a valid username
  exit 1

fi

Uid=$(id -u "$2")
Gid=$(id -g "$2")

# Now set for container ($1)
if [ "$(lxc list | grep "$1")" = "" ]; then
  echo \"$1\" is not a valid container name
  exit 2
fi

echo Setting  "uid $Uid 0\ngid $Gid 0" in container $1

printf "uid $Uid 0\ngid $Gid 0" | lxc config set "$1" raw.idmap -

echo Restarting container
lxc restart $1
19

Which nvidia drivers on the host to install? Ubuntu’s or NVIDIAs?

Is that first script ran on the host or the CT?

20

Install the Ubuntu vetted drivers.

The Nvidia .run file is difficult to manage when it comes to upgrading.
