Slow (?) HW-Transcoding with I5-11400 on Proxmox + Jellyfin via Docker - bentrades - 2025-01-02
Hi all,
I'm facing an issue with Jellyfin on my spouse's Android phone (S23) running Jellyfin app 2.6.2. Any content she watches gets transcoded, unlike when viewing via:
- Chromecast with Google TV (official Jellyfin App)
- Apple TV 4K (Infuse)
- iPhone (Streamyfin/Infuse)
I have 2160P HEVC content that gets transcoded to MP4 H264 AAC at 26.5 Mbps due to unsupported container and audio codec. My setup includes an i5-11400/UHD 730, showing 35 FPS during transcoding. I'm unsure if this is expected or a misconfiguration.
Here's my current setup:
- GPU Passthrough via Proxmox with /dev/dri in docker-compose
- intel_gpu_top in VM shows 70-80% utilization
- CPU (12 threads assigned via CPU Type: host to the VM) shows roughly 50% utilization
- Hardware Transcoding enabled for Intel QuickSync Video
Thanks for any insights!

RE: Slow (?) HW-Transcoding with I5-11400 on Proxmox + Jellyfin via Docker - TheDreadPirate - 2025-01-02
You didn't enable hardware transcoding. It is still software transcoding. Share screenshots of Dashboard > Playback > Transcoding
Code:
Stream #0:0 -> #0:0 (hevc (hevc_qsv) -> h264 (libx264))Also, is the Android phone using the web player or integrated player? Settings > Client settings. The integrated player will have better codec support.

Thanks for the quick reply, from what I think I have Hardware Transcoding activated. Find attached the Settings Screenshot.
Okay will take a look in the app, thanks for pointing me towards it!
edit: Changed it to integrated player like you said. Transcoding stopped <3
RE: Slow (?) HW-Transcoding with I5-11400 on Proxmox + Jellyfin via Docker - TheDreadPirate - 2025-01-02
You did not check the box "enable hardware encoding". You can also check "allow encoding in HEVC format" and both tone mapping boxes.

If I do this my transcoding from a different content fails, below is the ffmpeg log which kinda gives me the feeling i still have misconfigured it yet.

RE: Slow (?) HW-Transcoding with I5-11400 on Proxmox + Jellyfin via Docker - TheDreadPirate - 2025-01-02
I see that you enabled low power encoding. Did you install and setup the GuC and HuC firmware?
https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/#low-power-encoding
Those two settings are optional, btw. You can disable them if you don't want to bother setting up the firmware.
RE: Slow (?) HW-Transcoding with I5-11400 on Proxmox + Jellyfin via Docker - bentrades - 2025-01-02
I did the driver activation but are unable to get it working with both low power encoders checked.
However I was able I think to set up Hardware Based Transcoding and are now at 41 FPS when transcoding a HEVC 10bit SDR with 16 mbits to 15. And now really the CPU is just idling around how I expected it to be. Assuming i have reached the right configuration.
