Movie corruption when plex decodes 4K HDR

you have two methods:

(IF ffmpeg is installed) this is a 30 second sample

ffmpeg -i filename.ext -c:v copy -c:a copy -c:s copy -t 00:00:30 output.ext

‘ext’ is the file extension … keep the same for both input and output filenames.

-OR-

this is a 50 MB sample
dd if=input_filename.ext of=output_filename.ext bs=1M count=50

Why is there no news?

Expired soon, download soon

I’m sorry. Personal life does sometimes take priority.
I work only part-time. I do best i can.

Can you re-link?

I have now switched to LXC, but a decoder error has been prompted. I am very angry about this. I spent a lot of money to obtain Plex Pass Lifetime, but I have had a very bad experience. The official casual attitude makes me feel offended.

Got it. Thank you.



I needed to use a different test file which runs longer (the hardware transcoding was too fast for 30 seconds of video.

Do you have the Intel Compute Runtime libraries or Beignet installed on your machine?

If you do, they aren’t needed for Plex and should be removed.

I don’t have the Intel library installed, but it’s clear that it transcodes properly (errors usually occur immediately after decoding).

Is there anything you need in my newly provided logs?

At this point, there is nothing more to do except wait for me to understand ProxMox better.

I am learning it so I can try to help everyone. ProxMox isn’t officially supported but, if I can, I’ll figure it out.

I’m at the point now where it looks like I need to customize the PVE config to blacklist a whole bunch of drivers and change the grub config.

Does that sound familiar ?

Can we continue this question in discord? Posting in the forum prevents me from responding to you quickly.

Please.

I do not have discord account.

What IM software do you have?

@Sh_Cby

I’m sorry, I do engage in personal IM. Work is work and personal is personal.
Thank you for understanding.

Never mind, we can continue to communicate in this thread.

This is the way to reproduce my installation environment (please ensure that the environment is a host machine, not a virtual machine).

1.Please update the proxmox kernel to 6.1.6-1 first

apt install -y pve-kernel-6.1.6-1-pve pve-headers-6.1.6-1-pve

2.Pull code from this github repository:

3.Edit the dkms.conf and install the module

4.You should see multiple UHD 730 in the lspci after the step is completely completed.

5.Modify the /etc/default/grub file to

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on i915.enable_guc=7"

6.The installation tool modifies the sys parameter

apt install sysfsutils -y

echo "devices/pci0000:00/0000:00:02.0/sriov_numvfs = 7" > /etc/sysfs.conf

7.Don’t forget to update-grub and update-initramfs

These steps should require a lot of rebooting, which I’m sure you know better than I do.

I just searched for an article that should explain in more detail.
