NVdec supported format on Ada

I have hevc/h265 422 10bits and h264 422 10bits videos I am trying to decode with nvdec.
It seems to fail at (nvdecoder.cpp:196):

if (!decodecaps.bIsSupported)
{
	NVDEC_THROW_ERROR("Codec not supported on this GPU", CUDA_ERROR_NOT_SUPPORTED);

Can someone confirm wether those formats are supported or not or if I am doing something wrong with nvdec ?

regards

Hi @Gatchan, welcome back.

Chek out Video Encode and Decode GPU Support Matrix | NVIDIA Developer

I am afraid 422 10bit is not listed.

Thanks. Indeed, it’s not listed for h265, but nothing is listed for h264, does this mean that all 8/10/12 and chromas subsampling are supported ?

For h265, why 422 would not be supported but 420 and 444 yes, it’s supposed to be intermediate subsampling ?

422 is not suppprted at all on Nvidia
