[Bug]: AMD DX12 video encode driver bug?: Error using new FFMPEG HEVC D3D12 encoder support in Intel cartwheel repo..

[oscarbg]

Hi,
first sorry as this site is for reporting AMF video dec/enc bugs but found some issues using new HEVC D3D12VA encoder support in “Ffmpeg intel cartwheel github repo” and Intel engineer says no issues on Intel HW so can be a AMD driver bug and to request help from AMD guys..
Don’t know where to ask contact AMD DX12 team responsible for dx12 video encode decode apis so just asking here..
Please, can pass info of the bug to dx12 video team : intel/cartwheel-ffmpeg#311
These d3d12 encode patches should be in next ffmpeg 7.1 release so hope fixed before then..
Also I know building ffmpeg for windows with the d3d12 encode patches can be a bit of work so can provide a windows binary (ffmpeg.exe) if needed..
Thanks..

Describe the bug

New ffmpeg d3d12 hevc encoder fails on AMD using latest drivers on a Zen4 igpu..

To Reproduce

Steps to reproduce the behavior:

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

Setup (please complete the following information):
