I’m starting to get more and more HDR content, and I’m noticing an issue with my Jellyfin server. In nearly all cases, it’s required to transcode and tone map the HDR content. All of it is in 4k.
My little Quadro P400 just can’t keep up. Encoder and decoder usage hovers around 15-17%, but the GPU core usage is pinned at 100% the entire time, and my framerate doesn’t exceed 19fps, which makes the video skip so badly it’s unwatchable.
What’s a reasonable upgrade? I’m thinking about the P4000, but that might be excessive. Also, it needs to fit in a low-profile slot.
Edit: I’m shocked at how much good feedback I received on this post. Hopefully someone else will stumble on it in the future and be able to learn something. Ultimately, I decided to purchase a used RTX A2000 for just about $250. It’s massively overkill for transcoding/tone mapping 4k, but once I’m brave enough to risk breaking my Proxmox install and setting up vGPU, I’m hoping to take advantage of the Tensor cores for AI object detection in my Blue Iris VM. Also, the A2000 supports AV1, and while I don’t need that at the moment, it will be nice to have in the future, I think.
Final Edit: I replaced the Quadro P400 with an RTX A2000 today. With the P400, transcoding 4k HEVC HDR to 4k HEVC (or h264) SDR with tone mapping resulted in transcode rate of about 19fps with 100% GPU usage. With the A2000, I’m getting a transcode rate of about 120fps with around 30% GPU usage; plenty of room for growth if I add 1 or 2 users to the server. For $250, it was well worth the upgrade.
I’ve got a 1070 that I use for transcodes and some tonemapping where necessary and I don’t have GPU related issues (My ISP causes their own problems). I can usually run a few small streams at once, and I have a PC that I use to handle files too large to reliably stream to my Chromecast with Google TV over WiFi.
What kind of issues do you have with your ISP? I live in a rural area, so my options for ISP are limited; I have a VDSL connection supplemented by Starlink. Starlink uses CGNAT, so I can’t really host anything there unless I use something like Zerotier to Tailscale, but my VDSL connection works pretty well as long as I make sure to drop the bitrate to something that fits in my 4MBit upload. I have anything that accepts incoming connections behind an Nginx reverse proxy, and my routing policy is set up so that Nginx is forced onto the DSL connection.
Not really related to my original post, but I’ve spent way too much time tinkering with my network, so I was curious.
I guess compared to your situation, they’re fantastic. I have a static IP and copper connection, but they don’t offer any symmetric plans. I’m stuck with 200down/15up and the best up they offer is 500down/25up.
