NvCodec Decode crash on L4

I am having a strange issue on the L4. I have a video pipeline that is decoding H264 using NvCodec version 12.2.72 and it works just fine on an RTX 1070 for example but seems to be crashing on the L4 inside the NvCodec API,
-here to be exact:
in NvDecoder::Decode()
NVDEC_API_CALL(cuvidParseVideoData(m_hParser, &packet));

It does not throw an exception either.

It processes a number of packets before crashing, but never it never produces a frame.

Anyone have any ideas on how to debug this?
thanks!

Could you try with the latest driver. If the issue still persist, can you provide a reproducer with exact steps to reproduce this problem.

Hi Mandar,

I resolved the issue. It was a Microsoft problem with binary compatibility issues between vs2019 and vs2022 with respect to the std::mutex code. Upgrading the client machine to the latest Microsoft distributable binary for vs2022 solved the issue. NVDEC uses std::mutex which crashes because of this problem.
Thanks for getting back to me!
