Attempting hardware acceleration, ffmpeg -init_hw_device says "No device found" - guiniveretoo - 2023-07-21
I have all these lovely movies and shows that are 10-bit and the poor cpu just can't keep up with them, they stutter and jitter, on the computer, on my phone, on the TV (via Roku).
Ubuntu 22.04.2 LTS, Jellyfin 10.8.10, ffmpeg version 5.1.3-Jellyfin
We recently installed a Radeon 270, hoping that it would help. I'm not sure it was installed correctly, I'd love help diagnosing that if it's relevant. I'm trying to go through the steps here: https://jellyfin.org/docs/general/administration/hardware-acceleration/amd
I'm stuck on step 6:
Code:
$ sudo /usr/lib/jellyfin-ffmpeg/ffmpeg -v debug -init_hw_device opencl=ocl:.0,device_vendor="Advanced Micro Devices"

Jellyfin's documentation says you should be using VAAPI, but the documentation implies that it only works for Vega and newer? Otherwise use AMD AMF, but then you are dependent on the built in hardware decode/encode engine. UVD 4.0, the engine in the 270, only supports decoding H264 (assuming 8-bit). No H264 encoding support, meaning no accelerated transcoding. And no HEVC acceleration at all.

So basically, I'm SOL until I upgrade my hardware, is what I'm hearing? Thank you.

If your playback hardware supports your media natively, you can direct play without transcoding. No problem. But it sounds like that is not the case, which means you probably are SOL.
If you do decide to upgrade, let us know your budget and we can give suggestions. Look at my specs in my signature. It really doesn't take much hardware to have a good Jellyfin experience. It's just a matter of choosing the right hardware for your media (videos codec mostly).
For the record, what CPU do you have?

Old as shit, I know. It's an old desktop machine that was picked up from craigslist when someone was cleaning out their office. At this point, I'm not really expecting it to be good for much except the case, and maybe not even that. If we upgrade the GPU, we have to upgrade the motherboad essentially, and also the power.
I'd love recommedations for minimum GPUs that would run everything I'm wanting to watch. We don't have a 4k anything nor are we planning on getting any, I'm aiming for 1080p everything if I can. I don't have any specific upper limit (yay disposable income), just would prefer to stay on the lower end of the budget if possible (byebye disposable income).

You really don't need much to have a good Jellyfin experience (see the modest specs in my signature). It's all about matching the codecs your library is stored in with the right hardware. It's really a matter if you have AV1 media already or want to encode your library with AV1. If you don't care about AV1 at the moment, just about any 8th gen Intel CPU and newer will serve 5-10 users if transcoding. More users if there is no transcoding (don't count on this).
If you do care about AV1, any 13th gen Intel CPU will do. Or any CPU + Intel Arc A380.
I've posted this before in other threads, but here are the three tenants of a smooth Jellyfin exper
1. Know what server and playback hardware you have
2. Know what your server and playback hardware is capable of
3. Know your media library
When your library (mainly videos codecs) lines up with what your server GPU hardware can decode you will have a smooth transcode experience. When your library lines up with what your playback hardware can decode you will have a smooth direct play experience. When your library doesn't line up with your hardware's capabilities, you're going to have a bad time.
