    This is a HEVC videos 1080p (x265) maybe the Raspi HW HEVC decoder is not working. The Pi4 has a hardware HEVC decoder and must be enabled. See the Jellyfin documentation Hardware Acceleration

    Maybe this post is helpfull: Jellyfin Hardware Acceleration with docker

    Hello and thanks for the help!!

    In the "Hardware Accelearation" page, I read:

    Configure VAAPI for your system by following the relevant documentation. Verify that a render device is now present in /dev/dri, and note the permissions and group available to write to it, in this case render:

    $ ls -l /dev/dri
    total 0
    drwxr-xr-x 2 root root 100 Apr 13 16:37 by-path
    crw-rw---- 1 root video 226, 0 Apr 13 16:37 card0
    crw-rw---- 1 root video 226, 1 Apr 13 16:37 card1
    crw-rw---- 1 root render 226, 128 Apr 13 16:37 renderD128

    And when I try the same I get (in Portainer):

    root@OMV5:/# ls -l /dev/dri

    total 0

    crw-rw---- 1 root video 226, 0 Jan 4 13:12 card0

    crw-rw---- 1 root 107 226, 128 Jan 4 13:12 renderD128


    So, no "render" group. In the "relevant documentation" webpage I can not find the right way to configure it on RPI.

    In Portainer I get:

    root@OMV5:/# vainfo

    error: XDG_RUNTIME_DIR not set in the environment.

    error: can't connect to X server!

    libva info: VA-API version 1.4.0

    libva info: va_getDriverName() returns -1

    libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)

    vaInitialize failed with error code -1 (unknown libva error),exit


    Am I in the right direction? I Think that if I can config that group I can do the rest of the steps below:

    1. Add the Jellyfin service user to the above group to allow Jellyfin's FFMpeg process access to the device, and restart Jellyfin.
      sudo usermod -aG render jellyfin
      sudo systemctl restart jellyfin
    2. Configure VAAPI acceleration in the "Transcoding" page of the Admin Dashboard. Enter the /dev/dri/renderD128 device above as the VA API Device value.
    3. Watch a movie, and verify that transcoding is occurring by watching the ffmpeg-transcode-*.txt logs under /var/log/jellyfin and using radeontop or similar tools.

    Thanks a lot.

    Hello everyone,

    Lately I haven't been able to watch some films on Jellyfin. It is interrupting and unresponsive.

    Checking the system information, despite having an RPI 4 (8mb), I see that the processing is constantly at 100% with Jellyfin open. And when I try to see the film described in the attachment, I see that in the processes, FFMPEG is at 400% CPU usage.

    Is it a problem?

    Thank you for your help.


    Does the backup plugin allow you to create two scheduled jobs (one weekly and one daily) in different folders?

    My idea is to create a weekly backup (with the option to keep "0" copies) and through "duplicati" make a copy in the cloud.

    The daily backup (with the option to keep 3 copies) would be made a local backup.

    I tried to do what I wrote above but it didn't work. The two scheduled jobs wrote in the last selected folder.

    Thank you.

    Hello everyone,

    I would like to use an RP4 as a bluetooth receiver connected to a music distribution center (RCA input).

    Does anyone know of a project, preferably in a container?

    So I can use the same RP4 for a pi-hole server

    Thank you.

    Well, OMV is not only for RPi. And amd64 can use a lot of more energy.

    And one of the options is "reboot". Some people like to reboot their machine every now and then.

    Yes, I understand, but with these heavier and energy-hungry machines, wouldn't it make more sense to switch off at times when there will be no use?

    I think this comes from the legacy of the years using QNAPs.

    Thanks again.

    Did you test the sdcard Backup?


    I imported the file "ddful.gz" to the mac and flash it directly with Belena etcher.

    Everything worked almost perfectly.

    Plex initially opened, but did not find the files when trying to watch a movie. After restarting the container everything returned to normal.

    A few moments ago I installed some system updates and restarted OMV. Everything now is working fine, including Plex.

    I use duplicati on mac to backup documents to "". I will see the installation through the docker.

    I didn't know this pCloud. The 500gb lifetime access is very interesting, but I will test it with a free account.

    Did you test the sdcard Backup?

    Not yet. I ordered new SD cards, which are on the way and I will do a test.

    But I don't have Linux machines, only MacOS.

    I also ordered another 8mb RP4 to be a headless linux box so I can learn linux. After everything is ready I test the restore on a USB SDcard reader.

    You are missing off-site backup. Either in the cloud or on a portable drive that you store in another place.

    You might consider also replacing step 2 and 3 by using rsnapshot instead of rsync. Rsnapshot is easy to set up, but you need to think a bit how to restore (selecting the correct snapshot and how to copy the data back).


    I tried to put the 128gb USB card in the free usb3 port (the two 2T WD-REDs are in a single USD3 port) but the system failed to recognize the two main disks. I imagine that there is a limitation in the number of storage units, as it would be the fifth. After I disconnected the USB card everything went back to normal.

    Regarding the cloud, which one do you suggest and where can I see more information? Due to the size of the Backup folder, how would it be possible to choose the oldest backup (4 days) of 32gb? I could also possibly create another weekly backup of the system in a remote folder, but I have to learn how to do this (fresh noob here).

    I'm going to study rsnapshot, thanks for the tip.


    I am very happy with my OMV5 + Plex running on RP4 (8mb) after my second QNAP broke. I set up the whole system for the price they asked to fix it.

    I have the RP4 connected to a SATA-USB3 box with 2 WD-red of 2T. And two more 1T external USB hard drives.

    My current backup settings are:

    • Daily system backup (DD full). Option to store 4 days.
    • Weekly backup of the entire 2T disk to the second 2T sata disk, as instructed in the OMV5 installation guide, without the "--delete" argument, including the system backup folder.
    • Monthly backup of all 2T disk, as in the weekly one above, but WITH the "--delete" argument.
    • Weekly backup of all shared folders (movies, docs, system backup, etc.) individually for the two 1T disks (divided according to the folder size), without the "--delete" argument.

    I feel it could be safer if the system backup was not on the 4 hard drives connected to the RP4, but due to the size of the backup folder (128gb) I couldn't find a better option.

    Any thoughts?

    Thank you.


    I have received notifications of daily backups (DD full) and other RSYNC jobs in "scheduled jobs" (under "system").

    But I have not received notifications of system updates or RSYNC jobs scheduled in "services" and not in "scheduled jobs".

    I also notice that the outputs in the "syslog" of "rsync jobs" disappear. I see them when I manually perform a backup, but they disappear at the next system login.

    Thank you.
