So this is the debug output on my Jellyfin LXC container:

this will be a bit trial and error, but from the logs it seems it's down to libmfx not working as expected with this cpu. 12th gen is in an interesting spot where it's supported by both the older libmfx and the newer libvpl. try passing INTEL_MEDIA_RUNTIME=ONEVPL to the container

I just have seen it happens inside the LXC container already. Let me debug that first why it happens already at that stage. The LXC has the same config as the jellyfin one.

jellyfin-ffmpeg6 = does not work. jellyfin-ffmpeg5 = works Let me downgrade it in the microservices container.

svenger87OP•2y ago

@sogan works lol

I used this release. https://github.com/jellyfin/jellyfin-ffmpeg/releases/tag/v5.1.3-4 Don´t know if it makes sense to raise an issue in the repo.

Okay. But this seems to have an Issue with iPhone HEVC videos. Asking in the jellyfin discord. I was able to strip this down. Only 240fps SloMos are failing with QSV now. Thats an case where one could live with. But are you able to downgrade jellyfin-ffmpeg6 to 5.13?

13th gen cpus require libvpl which is shipped in 6.0. if it’s working with 5.1.3, i’m thinking that it’s because it’s using libmfx without any ambiguity

Bug #1970637 “ffmpeg depends on libmfx-gen1.2 on Alder Lake for ......

On Intel 12th gen CPUs (Alder Lake), ffmpeg requires package libmfx-gen1.2 to use QSV hardware decoding/encoding, but it's not marked as a dependency and therefore not installed with ffmpeg. As stated on https://github.com/Intel-Media-SDK/MediaSDK#media-sdk-support-matrix, ADL-S, ADL-P and future Intel CPUs are not supported by libmfxhw64.so.1....

svenger87OP•2y ago

Seems like a known bug

sogan•2y ago

that dependency caught my eye in the article you shared as well. can you try installing libmfx-gen1.2 to see if that works?

svenger87OP•2y ago

No. Doesn´t work.

Same issue here. Seems like there is no proper fix for ffmpeg6 yet.

sogan•2y ago

yeah at that point i'm running low on suggestions 😅 you could maybe try INTEL_MEDIA_RUNTIME=MSDK?

svenger87OP•2y ago

Tried. No difference.

sogan•2y ago

your best bet in that case is to just stick with the ffmpeg5 release you have installed. hopefully they release a fix for this

svenger87OP•2y ago

But that requires me to edit the container after every reboot and Immich update. Maybe I edit my systemd script to do that for me.

sogan•2y ago

you could make a dockerfile with the release as the base image and add the command to install jellyfin-ffmpeg5. not ideal, but it will at least make it less manual.

I extended ,my systemd startscript for immich. Pretty hacky but does what i need 😄
