How to build

  • Install the NVidia CUDA SDK

  • Clone NVidia NvPipe

  • webrtc requires static linking, so we must patch NvPipe

    • Change the cloned CMakeLists.txt to include:

      foreach(flag_var
        CMAKE_CXX_FLAGS CMAKE_CXX_FLAGS_DEBUG CMAKE_CXX_FLAGS_RELEASE
        CMAKE_CXX_FLAGS_MINSIZEREL CMAKE_CXX_FLAGS_RELWITHDEBINFO)
   if(${flag_var} MATCHES "/MD")
      string(REGEX REPLACE "/MD" "/MT" ${flag_var} "${${flag_var}}")
   endif(${flag_var} MATCHES "/MD")

endforeach(flag_var)

add_compile_definitions(_HAS_ITERATOR_DEBUGGING=0)
add_compile_definitions(_ITERATOR_DEBUG_LEVEL=0)

    • make the cuda_add_library static:

      cuda_add_library(${PROJECT_NAME} STATIC ${NVPIPE_SOURCES})

  • Also see the example CMakeLists.txt in this repo.

  • Then build and install the cmake project as usual, and copy the include and libs

  • You might want to update the static CUDA libraries too
