Fatal error with playback when hardware accelleration is enabled. - rob bindels - 2025-02-23
This is the situation:
Data is on a Qnap nas.
Jellyfin is installed on a N150 device, with Windows 11.
Jellyfin version is 10.10.6.
As the CPU is at 100% for playback, I thought to activate Transcoding.
I did select QSV. And then under Hardwarecoding I selected all, I could. And that works.
It even seems, that the GPU is now being used a bit (10/25%) and the CPU is still at 100%.
But it works.
As soon as I select under Options for hardwaredecoding: Hardwarecoding switch on, I get a fatal error.
This is for instance the Media info from one of the movies I tried:

Thanks ahead for any help.
As I am the only viewer of the system, Hardware accelleration is maybe not a needing thing, but if I read that others have 10 streams 1080, or 2 streams 4k, I wonder how to do that, if I am instantly on 100% cpu.

Can you share the ffmpeg logs of the failed playback attempt?

This is from the last movie, I tried.

RE: Fatal error with playback when hardware accelleration is enabled. - Efficient_Good_5784 - 2025-02-23
Looks like the iGPU can only decode AV1, not encode it.
Go into your dashboard, then to transcoding settings and disable the AV1 encoding option.
RE: Fatal error with playback when hardware accelleration is enabled. - rob bindels - 2025-02-23
That is it. Thank you.
CPU is now 70% and GPU 50% +/-.
Can we also see, why I am, if I translate that to the amount of streams, I am still getting to 1. Maybe 2, and it is only HD. Why do others get more? Or is it to difficult to say?

RE: Fatal error with playback when hardware accelleration is enabled. - Efficient_Good_5784 - 2025-02-23
The usage reported doesn't scale linearly for HWA. You can test out how many streams you can transcode at once by opening multiple browser tabs and forcing a transcode on each one.
RE: Fatal error with playback when hardware accelleration is enabled. - rob bindels - 2025-02-24
In the end I tried 3 streams, and that worked.
What I have noticed is that the CPU stays at 100% and the GPU went up to 75%.
And I have the idea that when you start a movie, that Jeffyfin starts working very, and processes the video faster then the duration of the movie. Lets say, movy of 2 hours, processed in 1 hour. And the CPU is then at 100% at work, and done after 1 hour.
Is my assumption correct?
Thanks foor the help.

RE: Fatal error with playback when hardware accelleration is enabled. - Efficient_Good_5784 - 2025-02-24
The transcode will be handled as fast as it can be by the hardware.
You can see the actual speed in the playback info tool from the video player.
It will tell you how much fps your transcode is running at and the actual speed ratio.
So if your video runs at 24fps and the transcode is happening at 48fps, Jellyfin will show this: "48fps (2.0X)"
In this example, "2.0X" means that the transcode is happening twice as fast which you can extrapolate to mean the transcode will finish in half the time it takes to watch the video.
Videos are transcoded into small chunks and are stored on the transcode folder.
These chunks get sent to the client that started the transcode.

Thank you for the explanation.
