Slow transcoding intel N5095 - superGoby - 2024-11-13
Hello, recently i got an intel n5095 mini pc and installed ubuntu sever 24. I followed the guide on how to activate hardware acceleration and it works fine but the problem is the transcoding is very slow. i wait 1s to watch 2s and sometimes i wait even more.
i use quick sync ( i tried VAAPI too and got the same results) and i'm not using tone mapping
here is the transcoding logs: (attached the full log below)
Code:
Stream mapping:
Stream #0:0 -> #0:0 (hevc (native) -> h264 (h264_qsv))
Stream #0:1 -> #0:1 (aac (native) -> aac (libfdk_aac))Also when i check intel_gpu_top i see the video in the gpu at 70/80% and also the cpu are at 100%
is this a hardware limit? or am I missing something?

It is transcoding faster than real time, so the issue is either client side or with the network speed. What client are you using?

Thank you for responding, i'm using jellyfin on the browser

Are you using the same PC you are running Jellyfin on as the client?

No i'm not, i installed jellyfin on my mini pc (not using docker) and i access it through the local IP on my browser

Can you do speed tests on both the server and client? The video in question is transcoding at over 100fps for a 24fps video. So the limitation is 1) the server can't serve the files fast enough due to resource starvation, 2) the server has a slow or inconsistent network connection, even though the video has a pretty low bit rate, or 3) the client has a slow or inconsistent network connection.

Hello again, Thank you for the reply, indeed the transcoding is working fine as you said i even tested it by throttling the transcoding and i see the cpu goes back to idle and the video still buffering. it is a network issue apparently
