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
