Qsv errors on Windows Intel Core i5-1235U

immausername

Hello,

I'm in the process of migrating over from a MacOS build to a Windows build. I've tried a few of the Hardware Acceleration options, I'm assuming I want to use Qsv since I have a processor that should be able to use Quick Sync. I keep getting errors like this:
ERR] HLS process for channel 13 has terminated unsuccessfully with exit code 1: [AVHWDeviceContext @ 0000022e524f3d40] Error creating a MFX session: -9.
Device creation failed: -1313558101.
Failed to set value 'qsv=hw:hw,child_device_type=dxva2' for option 'init_hw_device': Unknown error occurred
Error parsing global options: Unknown error occurred

Any ideas on how I can resolve this? I am logged in as the primary user on the machine and running ErsatzTV directly from there.

If it makes any difference this is the machine I'm setting up: Beelink Mini PC, Sei12 Intel 12th i5-1235U(Up to 4.4GHz, 10C/12T), Intel lris Xe Graphics
I've also tried using the latest version of FFMPEG.

To follow up, I've installed the latest intel drivers, ensured tone mapping was off, went into bios and directly enabled iGPU, updated windows to the latest version, searched through the intel software for any clues but to no avail. I also installed docker / WSL and tried to get things up and running that way, there I can at least select a device in the FFmpeg Profiles section, but I was unable to figure out how to get mapped drives to work inside of docker on windows to test and see if it works. Should I cut my losses and install Ubuntu / setup a dual boot system?

I can reproduce this on my Windows machine with Intel Iris Xe Graphics; will work on a fix.

I have the 1240P and am getting the same error

I'll get my Arc setup on Windows again and see how it behaves with QSV.

Please try the latest Windows develop build from https://github.com/ErsatzTV/ErsatzTV/releases/tag/develop - switching to Direct3D 11 for QSV accel in ffmpeg fixed things for me.

That works! thanks for that!

I'm having consistency issues now with it and i'm not sure whether it's my ffmpeg settings. I've tried default settings but some channels will work, others won't.

Looking through logs it comes up with this error "Unexpected pixel format null may have playback issues".

If I turn off HW acceleration it works but obviously smashes the cpu. I've tried the default settings and tweaked them too but can't seem to get it right. Any ideas?

nrage Can you clarify what you mean by "consistency issues"? What are the symptoms that something is behaving incorrectly?

The pixel format warning is always expected from Plex libraries since it doesn't return the pixel format from its API, and it can safely be ignored.

I will clarify my setup, I am using this through the plex live tv. ffmpeg settings are set at your default but I've also tweaked to try get it stable but with no success. any tips would be great.

Some channels will play, others won't. I think it's dependant on the show that's playing and this was both through plex and vlc. I seem to have just gotten it stable, auto deinterlace and normalise audio and keep it to h264 and 8bit. I'll keep an eye on it and report back any weirdness.
