This sample demonstrates CUDA-NvMedia interop via NvSciBuf/NvSciSync APIs. Note that this sample only supports cross build from x86_64 to aarch64, aarch64 native build is not supported. For detailed workflow of the sample please check cudaNvSciNvMedia_Readme.pdf in the sample directory.

Download and install the CUDA Toolkit 12.0 for your corresponding platform. Make sure the dependencies mentioned in Dependencies section above are installed.
The Linux samples are built using makefiles. To use the makefiles, change the current directory to the sample directory you wish to build, and run make:
$ cd <sample_dir>
$ make
The samples makefiles can take advantage of certain options:
-
TARGET_ARCH= - cross-compile targeting a specific architecture. Allowed architectures are aarch64. By default, TARGET_ARCH is set to HOST_ARCH. On a x86_64 machine, not setting TARGET_ARCH is the equivalent of setting TARGET_ARCH=x86_64.
$ make TARGET_ARCH=aarch64
See here for more details. -
dbg=1 - build with debug symbols
$ make dbg=1
-
SMS="A B ..." - override the SM architectures for which the sample will be built, where
"A B ..."
is a space-delimited list of SM architectures. For example, to generate SASS for SM 50 and SM 60, useSMS="50 60"
.$ make SMS="50 60"
-
HOST_COMPILER=<host_compiler> - override the default g++ host compiler. See the Linux Installation Guide for a list of supported host compilers.
$ make HOST_COMPILER=g++
