... and put them into new nvcodec plugin. * nvcodec plugin Now each nvenc and nvdec element is moved to be a part of nvcodec plugin for better interoperability. Additionally, cuda runtime API header dependencies (i.e., cuda_runtime_api.h and cuda_gl_interop.h) are removed. Note that cuda runtime APIs have prefix "cuda". Since 1.16 release with Windows support, only "cuda.h" and "cudaGL.h" dependent symbols have been used except for some defined types. However, those types could be replaced with other types which were defined by "cuda.h". * dynamic library loading CUDA library will be opened with g_module_open() instead of build-time linking. On Windows, nvcuda.dll is installed to system path by CUDA Toolkit installer, and on *nix, user should ensure that libcuda.so.1 can be loadable (i.e., via LD_LIBRARY_PATH or default dlopen path) Therefore, NVIDIA_VIDEO_CODEC_SDK_PATH env build time dependency for Windows is removed.
