    Hi,

    I am having similar issues with my setup:

    Host OS: Proxmox 9.0.11
    Container: Docker Container inside Proxmox VM (Debian 13, latest) running Jellyfin (4 vCPU / 12GB RAM)
    Hardware: N150 Mini-PC, 16 GB RAM, SSD
    Storage: RAID-1 NAS 1Gbit

    Logs and intel_gpu_top proof iGPU passthrough is working fine.
    Symptoms are pretty much the same as OP: Startup Jellyfin, play any kind of media and the Transcoding works perfectly fine, for a very short time. I have up to 10x transcoding ratio, but shortly after it drops to <1x and it ultimately results in stuttering playback.

    I have tested both, QSV and VAAPI, but my own benchmarks show QSV a little more performant.
    I observe high RAM usage, that also not really drops lower, at least according to the Proxmox Monitoring UI.
