Hi, can you send me a link to the sample code, I am confused as to why gstreamer is being called? I guess its because you don’t have FFMpeg. Unfortunately FFMpeg is required to parse the incoming bitstream, so cudacodec::VideoReader won’t work without it.
From your build it looks like you are building cudacodec, but NVDEC is not shown on the below line in your output,
YES (ver 11.4, CUFFT CUBLAS FAST_MATH)
this could be because FFMpeg isn’t present or it could be that you haven’t passed the location of the libnvcuvid.so to cmake
-DCUDA_nvcuvid_LIBRARY=<STUB_OR_DRIVER_LOCATION>/libnvcuvid.so
