QuickSync Transcoding issue with Intel Alder-Lake (UHD Graphics 770)

[rbjtech 5284]

Hi,

@softworkz

I'm reporting that there appears to be an issue with the default ffmpeg hardware transcoding configuration (on Emby release 4.6.4.0) when using a 12700K Alder-Lake with the UHD Graphics 770 (quicksync).

I've managed to get it working by removing the offending statement in the ffmpeg line using the Diagnostic Options - please see the attached logs for all the details.

I'm planning on doing a lot more testing this week now I have the server built - but this was an initial finding from a quick play.  I'll also test the Beta.

Intel Driver was 30.0.100.9928

Thanks.

Thanks for the report. 

You could have also moved all non-D3D11 QSV hw codecs to the top instead of using the diag option...

The question is - how does it look when it fails with DX11 (which your log doesn't cover)?

Ah, that's from the release version. Could you try with the latest beta?

Thanks,
