Error using new ffmpeg HEVC D3D12 encoder support.. (on both NV and AMD GPUs)

Hi,
built FFMPEG on Windows and simple testing fails on NV 3070 GPU..
I verify:
>Enabled encoders:
>d3d12va_encode

and ffmpeg -encoders:
>V....D hevc_d3d12va D3D12VA hevc encoder (codec hevc)

running:
>ffmpeg.exe -hwaccel d3d12va -hwaccel_output_format d3d12 -i c:\av1\input.mp4 -c:v hevc_d3d12va -acodec aac output.mp4

```

```

Start by reproducing the exact Windows command with the reported hevc_d3d12va encoder and review the Encode failed 16 and Invalid argument logs. Compare behavior on the reported NVIDIA and AMD GPUs; done means the command completes successfully without encoder errors.
