nvdec,nvenc: Port to dynamic library loading ... 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. 2019-05-17 13:27:50 +00:00			`nvcodec_sources = [`

nvcodec: Introduce NVIDA CUDA helpers New object and helper functions can remove duplicated code from nvenc/nvdec. Also this is prework for CUDA device context sharing among nvdec(s)/nvenc(s). 2018-11-23 13:01:41 +00:00			`'gstcudacontext.c',`

nvcodec: Add H264 stateless codec implementation Introduce GstH264Decoder based Nvidia H.264 decoder element. Similar the element factory name of to v4l2 stateless codec, this element can be configured with factory name "gstnvh264sldec". Note that "sl" in the name stands for "stateless" For now, existing nvh264dec covers more profile and formats (e.g., interlaced stream) than this implementation. However, this implementation allows us to control lower level parameters such as decoded picture buffer management and therefore we can get a chance to improve performance in terms of latency.
