hevcencode test code produces corrupted output on Tiger Lake

[GreystWdR]

Executing hevcencode test sample produces corrupted /tmp/test.265 output on TigerLake CPU.
Environment: ubuntu 23.10 + intel-media-va-non-free package.

Fresh build on similar environment on SkyLake CPU produces expected readable bitstream.
h264encode produces expected result on both CPU.

Fresh build ffmpeg execution with codec hevc_vaapi produces expected output.

hi GreystWdR,
Could you please share your command line?
And could you please dump driver follow this wiki https://github.com/intel/media-driver/wiki/Decode-and-Encode-Debug-Tool-and-surface-dump and share here?
Thanks.

Hi,
Running the sample with default arguments is enough to reproduce the pb so the command was simply ./hevcencode .
My guess is the the problem come from the initialization part in hevcencode sample as I was able to make the encoder work flawlessly with a recent ffmpeg build. I have tried to find the differences in the initialization code without success.
For now, I don't have access to a TigerLake platform anymore to generate the driver dump. I'll keep you updated if manage to get my hands on it again.
Cheers.
