Hardware transcoding weirdness with differing clients. - A-Gift-Of-Flame - 2025-04-30
My issue/ the issue I have found, is hardware encoding, both Nvenc, and Quicksync, fail to start media only when connecting to a hosted website, tested so far with Brave, Chrome, and Firefox.
This does not appear to be a codec issue, as h.264, and HEVC, were both tested.
When using Jellyfin Media Player, both work fine.
Starting off my server deployment is a Proxmox LXC, on a razer laptop with specs.
PROX HOST:
OS: Proxmox VE 8.4.1 x86_64
Host: Blade 15 Base Model (Early 2020) - RZ09-0328 5.04
Kernel: 6.8.12-10-pve
CPU: Intel i7-10750H (12) @ 5.000GHz
GPU: Intel CometLake-H GT2 [UHD Graphics]
GPU: NVIDIA GeForce RTX 2060 Mobile
LXC :
OS: Ubuntu 22.04.5 LTS x86_64
I don't know if this is helpful, necessarily since it works on JMP but I thought it best to lay it all out there.
This issue is easily replicable by logging into the web client.
I hope this is not me being a dumdum, any and all conversation surrounding hardware encoding issues seem to be with the setup itself, and not the web client, so I thought it best to make this post.
### Reproduction Steps
0? Use Jellyfin server LXC
1. Log in to Jellyfin web client
2. Enable hardware encoding
3. start any video media
4. Fails
### Expected/Actual behaviour
1. Enable hardware encoding
2. start any video media
3. successful start
### Logs
Quicksync

I am fairly certain this is actually a bug, however I got denied on github and told to go to troubleshooting.
So, here I am.
