422 conversion not working in 4.08

[wwaag76]

When trying to render a file which is 10bit 422 using the following command line:

qsvencc64 -i "H:\TestFootage\Panasonic S1-vlog\P1000045.MOV" --codec h264 --cqp 23 --quality fastest --colorrange tv --fps 60000/1001 --avsync forcecfr --audio-codec aac --audio-bitrate 128 --output-res 1920x1080 -o "C:\Temp\Test\Panny422.mp4" 2> “C:\Temp\422PannyError.txt”
I get the following error:

---

C:\Temp\Test\Panny422.mp4

Currently yuv422 surfaces are not supported by d3d9/d3d11 memory.
Switching to system memory.
Failed to initialize encode session. : undeveloped feature.

QSVEncC.exe finished with error!

Please advise. Thanks.

Would you share your system information?
YUV422 feature support is from Haswell Gen CPU/GPU or later.

It's an i8700K which I believe is CoffeeLake. Here's info from a successful Nvenc render.

Is your Intel GPU enabled?

[wwaag76]

Yes. Qsvenc works just fine with 420.

As I were not able to reproduce the issue in my IceLake, KabyLake or Haswell environments (all without dGPU), I think it might be related to an environment with dGPU.

As there is no way to test this on my environments, I decided to avoid this issue by a workaround, switching the GPU based YUV422→YUV420 conversion which seems to be causing this issue to the CPU based one in QSVEnc 4.09. Please have a try.

[wwaag76]

Works great. Thanks a lot.

[rigaya]

Thanks for confirming, nice to hear it works!
